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.
