2010 Toyota Prius - Excessive Oil Consumption
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".
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.
