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.

I have experienced the ultimate problem with my 2009 Toyota Corolla and now the engine is not operable due to an engine knock... Where is the class action law suit I want to join?

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.

My 2011 Prius is burning about 1qt of oil every 1500 miles. It has 95k miles on it. The dealer and mechanic have said this is "normal for older prius engines". This is ridiculous. Very disappointed in Toyota.

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.

2010 Prius owner here. Started excessive oil burn at 80K miles. Now at 175K miles and burning a quart every 1,300 miles!!!

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 2010 Prius which I bought new. All my services have been done with Toyota dealerships. At 120K miles I started the issue of extreme oil consumption. Any case open to resolve this issue?

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.

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.

At 100,000 miles my 2010 prius started consuming about 1 qt. every 1000 miles. Now, they are suggesting that I need to replace the engine. Show me the class action lawsuit.

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?
