Nine problems related to engine burning oil have been reported for the 2012 Toyota Prius. The most recently reported issues are listed below.
This vehicle has been burning oil for the past 10,000 miles. Vehicle has had all services and synthetic oil changes done from day 1 at the dealership. Oil changes every 5,000 miles since day 1. At 90,000 miles the car started burning oil excessively. Complaints and diagnostics were attempted at Toyota franchise dealerships but they failed to find the issue. Finally at 100,000 miles the engine failed due to head gasket failure. This vehicle is classified as a partial zero emission vehicle and it is registered in a state that follows California air resource board regulations and is being serviced in a state that follows as well. Under the pzev regulations, Toyota warranties emission related components for 15 years or 150,000 miles. Under Toyotas warranty guide it states seals and gaskets are covered. The manual does not clarify any further leaving the coverage level vague and questionable. Upon trying to get Toyota to replace the engine, they gave us a week of no responses and finally declining the claim even when the manual states it should be covered. The oil burning issue with this motor is a big problem that Toyota has been trying to cover up. Toyota is quoting $13,000 for engine replacement. They have a service bulleting regarding the oil burning because it's a known issue, but they only honor claims under the 5 year 60,000 miles power train warranty.
Vehicle has been consuming oil to the point where the vehicle needs monthly oil changes. Was told many Toyota Prius models have had an oil consumption issue and that I should file a complaint.
The engine went stalled in the middle of the highway. Lucky enough, I was able to stop the car safely without any collusion. Brought the vehicle to a mechanic and diagnosed with excessive consumption of engine oil. The engine had catastrophic damage and needed a replacement. I spoke to piercey Toyota service director ken johnson and he stated there is no active recall for the vehicle and do not believe it is the vehicle issue. I do not believe that is the case, further investigation is needed to prevent other same model drivers from a deadly engine stalling crash.
Bought this car brand new in 2012 and have always performed maintenance on time. Between the last oil change and this oil change the Prius is burning oil and I am having to add at least two quarts of oil before it is back on the dipstick. I am noticing this is a problem with the 2010-2014 Prius and that Toyota has done nothing to solve it. I do not want to be on a long trip and burn through oil and lock my engine up causing harm to myself or others.
My car is burning excessive oil.
My car has started to burn oil at an alarming rate: 2 quarts between oil changes at 5,000 miles. This does not seem normal. There does not appear to be a leak.
My pruis is burning oil at a faster rate than it should be.
Excessive oil consumption started 70,000 miles. Burn oil 1qt every 1000 miles getting worse.
Excess oil consumption.
