2010 Toyota Prius - Excessive Oil Consumption

Issue Status: Discussion

I own a Toyota 2010 Prius that is using excessive oil. The dealer put the vehicle through an "Oil Consumption Test". After 1103 miles, the vehicle had consumed 3/4 qt which translates to 6.35 qt between oil changes. I have an extended warranty to 100K. Current miles: 89100. The dealer informed me that "Normal" was 1.1 qt/600 miles and would not honor the extended warranty. I opened a case number with Toyota America who also refuses to deal with the issue. I have owned three previous Toyota vehicles and several other cars through the years and NOT a single company would consider 1.1 qt in 600 miles as "normal".

This is on a 2010 prius with the 2ZR-FXE engine. I bought the car new in 2010.

At 30k miles, dealer found an oil leak. Okay no problemo, dealer took care of everything. This was with factory warranty. It ended up needing a head gasket replacement.

Around 79k miles, I would get a hazard light come up but then disappear very quickly. Usually when I was braking or cornering. I was able to see it was the low oil pressure light. I took it in immediately to the dealer for the 80k mi service. The tech noted that my oil was low.

Then around 82K miles, the same thing started happening again and I noticed my car was low on oil by about 2 quarts. I googled this problem and saw many reports of this issue with Gen3 models starting around 80k miles.

I immediately took the car to get a oil consumption test done with the dealer and they said it is burning 1 quart every 1000 miles. I have a platinum care 100k/7yr extended warranty. Toyota Financial (the people who sell toyota extended waranties) tell me that regardless of a pass or fail on the test, they would not authorize the dealer to diagnose my issue. I had to put money down upfront to do a teardown of the engine, if and only if, the dealer found a defective part (and not just "normal" engine wear), would the warranty cover anything. So at this point, extended warranties are pretty worthless, b/c you're liable up front, and unless you're damned 110% sure something is an issue, you are SOL.

The same issue with excessive oil consumption with a 2010 Prius. The problem started just outside of warranty period at around 90,000 to 100,000 miles. Same problem with Toyota not owning the issue.

My 2010 Toyota Prius is using a quart of oil every 500 miles now. It has 112,000 miles on it. The dealer commented on the oil consumption the last time I brought it in for an oil change just under 100,000 miles. It only had 8,000 miles on it from the last oil change. I anted it checked out before the warrantee ran out.

2010 Prius 62,000 miles failed oil consumption test. Car is currently at the dealership. The mechanics at the dealership used a scope to look inside the engine and discovered that the valves, seals, and rings are bad. Service Manager Mike stated that the pistons are probably bad as well. He said that he will call Platinum Care to find out if the extended warranty will cover the fixes. I got a phone call from the dealership stating that Platinum Care wants a complete tear down to look at the "head" and wants an inspector to look at the engine before declaring the problem as a warrantable fix. I was warned by the dealership that if Platinum Care determines after the tear down that it is non-warrantable then I am responsible for the tear down bill, which is between $1,000-$1,600. I am so frustrated with this whole process. My car started having issues when it turned 58,000 miles. I have been dealing with this failed oil consumption test for over 6 months and am running out of patience. If this problem is not fixed by Toyota at their expense I don't know what i'd do. This will be my last Toyota regardless of the outcome. This sucks big time.

I also have a 2010 Prius with the high oil consumption problem. I have always had the oil changed at Toyota dealerships, on time, and with synthetic oil. My increased oil consumption started at about 150K, I have about 180K on it now and was hoping for 250K+ as I am accustom to performance like that from Toyota vehicles... I've been told the acceptable consumption rate is 1 qt/600 miles! It would smoke like a diesel at that point! It's very disappointing to say the least.

I am also a 2010 Prius Owner in Chicago. I've been experiencing the excessive oil consumption for over a year. I am at 108K miles on the car. On Jan 2, 2000 miles short of my next scheduled oil change, I had to add three quartz. I did not get the oil warning light until it was almost empty. I had the dealership do one of those oil consumption tests a year ago, and they told me it was natural for a car as it aged to start experiencing this problem. I was at the dealership yesterday and registered the same complaint. They offered to do another oil consumption test.

My 2010 toyota prius with 99k miles is burning a little more than 1 quart / 1000 miles. At around 92k miles, 3k after an oil change, I had to add 3 quarts of oil just to see oil on the dipstick. At this point, I've been adding 1 quart of oil every 2 weeks. Of course the dealership says they haven'the heard of any oil consumption issues with 3rd gen priuses and that I would need to pay for any repairs associated with this out of my own pocket. My loyalty to Toyota is over.

I am having the same problem with my 2010 toyota prius. It started burning excessive oil at 93,00 miles. The low oil pressure light came on and went off so fast it took me more than a week to be able to read that it said. I added some oil and took it in. They said there was a small leak near the steering column which they fixed and I thought all was well. Less than 3,000 miles later when I went to get the card smogged, no oil was registering on the stick. They were alarmed. I drove back to Toyota with no oil registering on the stick as they instructed me. Now they made me get yet another oil change and go through an oil consumption test. It burned 3/4 of a quart of oil in less than 1300 miles and they sent me away. I spent the day on the phone getting no help frpm Toyota or the warranty people. What are they waiting for? People to die in seized up cars that burn to make right on faulty pistons and valves? Is that cheaper than nipping the problem in the bud? Or do we really have to wait for disaster to react to make things right Toyota? You are going to lost some very long term customers and pay dearly when this boils down to yet one more law suit? Where can we we sign up to be included in the next Toyota lawsuit? Please let me know.

I have a 2012 Prius that started consuming oil at around 100K miles. My wife drives the car and I'm gone most of the time. The engine oil light started coming on and by the 10,000 mile interval there was nearly no oil in the engine. Now the car has 140K miles and the condition has worsened to every 5000k miles there is no oil in the engine. All I have from the dealership is wanting to do a consumption test. Nothing from Toyota admitting that there is an issue with the prius engine. Makes no since to have a motor that is in perfect working condition that goes from no consumption to complete consumption nearly over night.

Dealing with the same issue. 2010 Toyota Prius with 99,000 miles on it. This issue has been happening since I bought the car in Sept with 94,000 miles on it. I just completed an oil consumption test with the Toyota dealer. I burned 3 qts in 1100 miles. There is a bulletin out by Toyota (Nov 16, 2016) that is effective for this issue on 2010-2014 Prius, 2012-2014 Prius V, and 2010, 2012-2014 Prius PHV. The failure level is 1 quart in 1100-1300 miles. They will only pay half of repair cost ($3000) because my prius is outside of "5 years or 60,000 miles" warranty limit. Seems to me this is a known issue, the 2010 prius wouldn't even be applicable for this warranty because it is inherently older than 5 years, and Toyota appears to be admitting fault yet refusing to pay the full cost. Was told that apparently the last two cases like mine had only been asked to pay $250 for repairs, which is why they guessed it would be that much. Very frustrated with the customer support Toyota is offering regarding this matter.

Myself as well, 2010, approx. 2 qt every 10K miles. Spoke with"Toyota Experience Representative" at 1 (800) 331-4331( Choose Recall). Recieved case number, however rep indicated "zero support" available. No more TOY-ota purchases by me! I should probable pay for a oil consumption test myself just in case TOY-ota admits that they're combustion engine design for these model/years is flawed.

Similar oil usage issue on my 2010 Prius. Car purchased new and serviced at Toyota dealership every 10,000 miles using 0-20W synthetic oil. At around 106,000 miles I noticed the display flashing something but could not, at that time, read what the warning was. It seemed to happen going around curves, turning etc. Finally, at maybe 107,000 miles, the warning stayed on long enough to see the low oil warning. Took the car in at 108,000 (no oil on dipstick at that point) and the service department checked for leaks and found none. I was lightly admonished by service for driving without oil. Fair enough, I thought at the time. I was slightly chagrined as I have always religiously had my oil changed (or changed it myself) on all my cars at the recommended intervals with no signs of a problem. The Toyota service department recommended that I monitor oil usage. I did, and to my surprise 2,500 hundred miles later, I had to add a full quart. Then 1950 miles later, another quart. Yesterday, another quart at 1048 miles. Very disappointed as the car has been without problems until now. Have not discussed this with the dealership, but am not encouraged by the tenor of comments posted here regarding Toyota stepping up and accepting responsibility. I see no need, at this point, to pay to have an oil consumption test done by the dealership as the car is obviously using an excessive amount of oil.

I have similar oil consumption issues that started around 90K miles. Now I monitor it routinely and find it needing a quart about every 1200 miles. At the last change, I went from 0W20 oil to 5W20 which seems to have reduced consumption in my case by some. Dealer and Toyota are useless. They will not be seeing me in their showrooms ever again.


Jeff B. said

Given that all this oil is burning and heading out the tail pipe, it seems unlikely that the vehicles are meeting their emission specs. Given what happened with VW Diesels, perhaps its time to contact the EPA. Maybe an EPA investigation with the potential of $Billion+ fines would get Toyota's attention.

My 2010 Prius consumes a lot of oil I regularly check and fill it. Last night I started my car and it was very very rough it sounds like the engine is going to fall out. My vehicle was also one of the ones that had recall work done for engine noise that I believe was due to some kind of computer problem?
I believe there are many many complaints internet wide on this engine/oil issue.

My wife's 2010 Prius is consuming oil at 110k miles. It was 2+ quarts low when I noticed the warning light flashing briefly while braking and turning right. I haven't discussed with the dealership yet. What is different on the 2010 Prius that makes it burn more oil than the other years? Or is it happening on all of them? If the engine rebuild is the solution, does it correct the problem or is the problem going to happen again in X number of miles?

My 2010 Prius started having oil issues right after about 110K miles. I drive a LOT - over 2K miles a month, so this is very problematic. When I talked to Toyota about it, all they said to me is "yeah, some Priuses burn oil". Not really an acceptable answer

2010 Prius
At 149 k miles, flickering oil light, not recognized immediately because liglt flickered off as fast as it flickered on. Finally I saw it was oil light on, checked and no oil on dipstick! Took it in immediately and it was down at least 4 quarts. Never had forewarning of this problem, the onset of wasting oil came on suddenly. Have changed my oil religiously because I had always felt a Toyoto would last forever (more than 300 k miles) if taken care of. Was advised by Toyota dealer "oh yea "Prius' do this". My brother's Prius doesn't do this. I now replace my oil at least one time over between oil changes, one quart every 500 miles and I buy it by the gallon. Is it still necessary to go in for routine oil changes? Class action lawsuit, count me in

My problem began at 125K a month after an oil change(maybe 1000 miles) with my low oil pressure light coming on. I take it in assuming the dealership made a mistakr this time under filling. They told me it was dry, near 0 oil in it, if they did fill it correctly it ate over 3 quarts in 1000. 2 weeks later the full oil change refill(500-700 miles later) is gone again, I took it upon myself to put in a quart, 2 days, ~150 miles later, dry dipstick. At this point I spend more on oil than gas, something is definitely wrong with these engine and it seems whatever went wrong with mine at 125K went real wrong. I assure you Toyota will be held responsible due to the hundereds of noted cases and the sudden severity of my problem. A quart a month sure, a quart a week(which is burning by the way, I saw my first faint smoke near my headlight today) is inexcusable and inoperable. That means I can't trust it for a road trip, a 2010 model in 2017 non-road ready is rediculous. Toyota will be hearing from me swiftly and abruptly in this coming week. I expected ~250K of drivability from my $27,000 investment and I will be getting it.
By design 4 quarts of their synthetic is suppose to run 7-10,000miles though I myself stick to the 7,000, in my cars current trend 4 quarts would last me 1,500-2,000 and risk siezing, unacceptable.

2010 Toyota Prius started drinking a couple quarts per 1000 miles when the odometer hit just over 120k miles. It is getting worse and won't even make it between oil changes before the engine is bone dry. Also have the same issue with low oil pressure lights flashing every time you take a turn. Toyotas new automatic oil change feature is not in the manual. I appreciate the thought but I really don't mind changing the oil. I would've never thought this would be an issue with Toyota or the Prius. I also can't believe I traded my cadilac cts for this trash because I thought the Prius was more "reliable" and cheaper to fix. I will never buy another Toyota product again in my life unless this is resolved.

Same problem here. 2011 prius, 2 qts per 1000 miles. So, that's 20 quarts between oil changes. 5 GALLONS of oil burning between changes. Toyota Customer Care said do the oil consumption test so I did. Obviously it failed. I call the, back and tell them it failed and they reply with too bad, so sad. Not sure why they told me to do it since regardless of the outcome they said my car isn't covered so any fix is at my expense. Bought based on rave reviews, high mpg, and low maintenance. And so much for it being green since it's pumping gallons of oil out the tailpipe every year. Had i known this would occur I never would have bought it. Can't even sell it without feeling guilty. Toyota sold me a ticking time bomb. Shame on them.

My 2011 Toyota Prius is currently just over 108K miles. About a week ago I noticed during wide turns a light coming on, but it would come and go so fast that I was unable to read it. Eventually I saw it was flashing low engine oil pressure. I take it in to the shop I normally get my oil changes and they let me know my car is not leaking oil but instead the engine is burning oil. They notify and let me know that this is a manufacturing issue that the dealership is responsible for fixing. So I call the Keyes Toyota dealership in Van Nuys and they let me know that since I am 8K miles over my extended warranty I would roughly be paying around $3500 for repairs out of pocket. I don't know what the warranty has anything to do with is if this is a manufacturing error that Toyota should be held responsible for fixing. I call another Toyota Dealership and they schedule a mileage test for me, which is tomorrow morning. But I'm already dreading the experience just by everyone else's experience with the SAME EXACT ISSUE. We need to get together and file a class action lawsuit so we can get a recall going on! This is not my first bad experience with Toyota and after this I don't think it's very likely I'd ever buy a Toyota again. Has anyone had their car fixed? Please let me know! What did everyone do after not getting it fixed through the dealership?

So happy to have found this! I thought I was going crazy! I've been told it's 'normal' and that 'since the engine is little, it doesn't hold much oil'.....I drive back and forth to AZ from CA on a regular basis and now have to constantly check and refill my oil. I carry extra oil in the car just in case! I just had to have my catalytic converter replaced due to it being 100% clogged....I'm absolutely convinced that the burning oil contributed to this. My car has 168,000 miles on it.... so frustrated! I'm all in for a class-action suit; it sounds like many of us are in the same boat. I want my money back.

I am in the same boat as everyone else here. My 2010 Prius is burning about 1.5 qts every 1000 miles. I was told my engine needed to be replaced and my catalytic converter also needed to be replaced because it was so clogged nothing is coming out of the tail pipe. I am appalled that Toyota is not dealing with this issue and would also like to join a class action if one is started.

Same problem here. 2010 Prius 100,000 miles the warning light came on as I was braking and going around a corner. Did an Internet search and found the low oil issue. Checked the oil, and had to add 2.5 quarts! Will have to watch oil consumption for the next month or so to see how much it is burning.

Took it to Toyota and they want to do an oil consumption test. They mentioned the TSB for other models but nothing for Prius. They "documented the issue" in case Toyota adds the Prius to the list of models with this problem.

Has anyone had any luck replacing PCV valve to remedy (at least partially) this issue?

Would be interested in joining a class-action if one happens.

I also have a 2011 Prius that is using one quart of oil every 600 miles. I have had it checked by two mechanics for a leak and neither could find any evidence of a leak.

Toyota TSBs for this problem are 0168-16 for test and 0169-16 for repair.
This bulletin applies to vehicles produced BEFORE the Production Change Effective VINs shown below.
MODEL PLANT PRODUCTION CHANGE EFFECTIVE VIN
Prius 2ZR-FXE JTDKN3DU#E1791355
Prius V JTDZN3EU#EJ001475
Prius PHV JTDKN3DP#E3055768

My Brother has this problem with his Prius and his car is burning oil.
It looks like Toyota diagnosed the problem and came up with a fix years ago.

Such bad customer service on a car I planned on driving past 300k :(

Yep. Same issue. 2010 Prius, serviced regularly and only at dealer where purchased, in Auburn, CA. Had the 120,000 mile service done a tad early, last month, at 118,689 miles, as warning light and beeping sound when braking/turning was happening. They said it was the oil, replaced it, told me older car needs oil more frequently, blah, blah, blah.... Took it back today because I was getting warning signals again, after only 121,867 miles, and there was pretty much zero oil in it; it took 3 1/2+ quarts! I was given the same spiel as others, and told to check the oil at every other fill up. I am not a car expert, but I know that the Prius uses synthetic oil which is supposed to last for longer than normal car oil, and I have never had any kind of car that went through oil this quickly.

My 2010 Prius just developed the same oil consumption problem at 160,000. All of a sudden is burned 3.5 quarts of oil in 2,500 miles. I just replaced the hybrid battery for $3,000 last month and now this. I paid $32,000 for this car and feel robbed. I never could have imagined that a Toyota I bought new and had serviced religiously at the dealer would not last 8 years! So much for the green reputation of Prius. Burning that much oil I feel like I should be driving a hummer. Toyota offered me their condolences but said they had never heard of this issue.

I have a 2010 Prius at 175,000 and it was occasionally flashing a warning light. I finally looked into it today and the oil was WAY LOW. So low that it took 2 quarts just to get to the minimum marker on the oil stick. Haven't done an oil consumption test, but it sounds identical to many of the above. I want to drive this car to 250,000 miles, I hope. So this is bad news.

I also have a 2010 Toyota Prius that is burning excessive oil!!! I drive ALOT (back and forth between Ohio/Tennessee) and I have to check EVERY time, that means EVERY week adding oil!!! It is getting ridiculous.

2010 Prius here, 92000 miles, burning oil, about 2 quarts for 2500 miles. Extremely dissapointed after researching that this is a highly common problem, Ive lost faith in my Prius, I can see the future of this car and its going to become a nightmare, I just know it. Time to sell it off.

After reading all of these posts, I owe my service garage mechanic an apology. Had my oil changed at 97,500 miles, he gave me a look at the dip stick to show the current levels both before and after the oil change.
Six weeks later I started getting a beep and a flash of a warning light on my dash that was to quick to make out. Researched it on-line and found lots of other people had this with their 2010, 2011 & 2012 Prius's. Turns out it's Low oil!!
Added 2 quarts and drove to my service garage and chewed them out for not tightening the oil plug or oil filter. They would not let me into the pit under the car to see where the leak was because of insurance reasons. They did take a picture to show me there was no oil leakage signs. Because of my demeanor they added one more quart of oil to top it off. That meant the motor was 3 quarts low in less than 5,000 miles of driving. The tech pointed out that he noticed around 100k miles this series of Prius started having oil usage issues. I had an attitude and told him it was a typical CYA response.
When I returned home I researched it. Sure enough, I found many dozens of posts dealing with 2010, 20111 and 2012 Prius cars that around 90,000 to 110,000 miles they started to consume excessive amounts of oil. I still own my first 2002 Prius with over 230,000 miles on it. No issues at all. This leads me to believe this is defiantly a materials type design flaw. So many cars in the same range starting to fail. If anyone know of a class action law suite taking place, I am in!!

I have 2010 Prius and it is using excessive oil. Over 1qt every 1000 miles and getting worse. Currently at 128,600 miles. Took it to the Toyota dealer and they said that the issue is weak Piston rings, but that there is no TSB or recall on the Prius. They said Toyota considers that level of consumption normal!!! I have 4 other brands of cars not Toyota and never have to add oil to any of them and they have a lot of miles as well. Toyota not owning up to a design flaw.

Its a joke, I've called Toyota on the issue and they refer you to the dealers for an oil consumption test and stand by the 1qt per 500 miles being poor but then all the repairs are out of your pocket and not covered. They have sold almost 1 million Prius since 2010 and it seems like all the engines take a shit after 100k miles...that is crazy for nothing to happen. But us regular people with no money and lawyers.....guess we have to just deal with it or sell the cars.

Simply, yes Toyota, Toyotas and their dealers suck. I have a 2010 Prius that burns more boil than 1978 Ford V8 with 400000 miles. Iwould do anything to stick it to these greedy f__ks. I will never personally by another Toyota as they are crooks. I will forever tell anyone I can to avoid Toyotas - all of their cars and trucks, you just can't ever expect them to do the right thing. They are all scumbags. The Federal and state governments should sue them as well for knowingly producing vehicles that are sold as "green" vehicles but are some of the worst polluters on the road.

Very well known issue, my 2010 is on it's second gas motor @ 304 K miles. Oil consumption is now an issue again, as it was on the first gas engine and this engine now has about 100 K on it.
It is a design defect for this engine.

I have this issue as well. I have right about 120K miles on my 2011 Prius and am burning a quart of oil every 1000 to 1500 miles. I changed the PCV valve to see if that helped, but it doesn't help if your power bar is full. At lower throttle settings, it seems to consume very little oil, but that is still a mechanical problem. You should be able to use full throttle without having to worry about sucking oil into your intake. I removed my intake to replace the PCV valve and found the intake ports covered in carbon deposits and liquid oil on the intake gasket.

I have 2010 Prius that uses 7 quarts of oil every 10,000 miles. I had 2 oil consumption tests and failed both according to Toyota. My Prius needed an oil change so I took it to a private garage. They only work on Toyota and Honda vehicles and have 5 star rating. I shared my problem with them and they gave me the info in the below link. The fix will cost $2,850-3,000. Toyota determines the definition of excessive oil consumption.

2011 Prius bought new. Massive oil consumption since 50000 miles. Probably before that but, since Toyota recommends 10000 oil changes I didn’t notice.
Was told this is acceptable and not warrantied. Rediculous.now have 155000 on the car. Change oil every 5000 miles and always put at least 4 quarts in between changes. Rediculous Toyota.

I own a 2010 Prius. 1rst experience of low oil was Around 112000 miles. Since then I have been adding oil between oil changes. After going through Toyota oil consumption test, Toyota service writer and tech advised 1/2 court per 1100 miles was good. Which would add up to 2qts/4400 miles. They advised it was normal for an older car to burn more oil. They also stated 1qt/600 miles was normal according to Toyota’s Vehicle manual. Which is basically, legal verbage to justify the overconsumption of oil with the model year Prius’s having the mechanically defective issue. I was also told by toyota customer care and the dealership,” they’ve not received ally of complaints “. Bullshit! I currently have 160000 miles.

My 2001 Mitsubishi doesn’t burn oil and I have 178000 miles on it.

I am currently having SAME issue with my 2010 Prius. Ours is just shy of 142,000 miles. We bought certified pre-owned with less than 20k miles. I kept getting the flashing warning ⚠️ light when I would make a sharp turn or quick stop, thought it was related to needing 2 new tires. My oil change was not due for another 400miles (per my mechanics 6,000 sticker. (Another selling point for me was that the hybrid could go 7,500 between oil changes). Saw the ‘low oil oressure’ Alert flash quickly and checked my oil. It was no existent. Didn’t even show on dip-stick! I drive far for work and this could ha e left me stranded on horrible highways. Spoke with my mechanic who recently saw this problem with another Prius and said same as above, carbon build up on rings that make them not function properly- oil then splashed up and out and burns. He stared Toyota’s fix is to replace rings but not a real viable option when it comes to cost. Seems Toyota isn’t taking responsibility for what’s seems a a manufacturing problem. What a waste on so many levels. The point of a hybrid is to be eco-friendly, point of always buying Toyota is quality. Well no-more. Scam and laziness on such a grand scale. I’m furious. There has to be something we can do to change this problem w/o breaking our bank.

My 2010 Prius had the same burning oil problem a few weeks ago. When the yellow warning light flash long enough for me to see the "Low Engine Oil Pressure" sign, I took it to the Toyota dealer, whom I bought the car, as well as doing my regular maintenance. I can tell they know the problem because they told me that my engine is burning oil, even before they pop open my hook. They have to add 3.8 quart of oil (I only drove about 800 miles since my last regular maintenance. They told me they can rebuild my engine but it will cost me $4,950 before tax. Obviously, I am not going to spend this amount of money for a 7 years old, 109,000 miles car. I will just keep driving and add oil until it dies. I have told all my friends about this problem and warn them that Toyota is not as reliable as many had thought. Personally I will never buy another Toyota myself.

Same issue here as most others. At a little over 100k miles I started experiencing the oil light coming on in between oil changes and when I would check it, it would be quarts low. Of course Toyota doesn't want to take responsibility for this issue. The problem with the oil burning is so bad it clogged my catalytic converter and I had to replace that.

This car sucks. Right after the 100,000 mile warranty runs out it starts burning about a quart of oil every 600 miles. At the 191,000 mile mark it finally gave up and I had to purchase another engine but I'm sure when this one hits 100,000 it will do the same thing. You can bet I will never buy another Prius, which sucks because I loved this car.
