Seven problems related to engine burning oil have been reported for the 2008 Toyota Prius. The most recently reported issues are listed below.
Son was driving car on city street going around 35 mph, then 20 brakes went out completely until parked. Started with a loud beep noise, lights on dash then brakes no longer worked. He had to push as hard as he could to try and at least slow car down not to hit car in front of him, pulled into bike lane to avoid crash as car would not stop. Turned car off and left in parking lot. I went to get car to drive home and then brakes were working. However scared to let him drive it in case issues happen s again. Have not taken to dealership yet. The other issue is since we purchase the car burns oil, car has around 130k miles and before 3000 miles up have less then quart of oil and no. Lwaks in drive way therefore feel it must be buring oil. Add ouk at each gass fill up to avoid no oil.
Defective engine required replacement prior to 139k miles (due to cylinder malfunction and excessive oil consumption), at a cost of $3700 for a used one. This has also damaged the catalytic converter, quoted at $900. At 149k miles, the hybrid battery has failed as well, which has a quoted replacement cost of $2400. While slightly outside of warranty, the engine and hybrid battery are both core components that are expected to last significantly longer. In carb states, Toyota even warrants the hybrid battery for 150k miles. The cost of replacing them exceeds the kbb value of the car, which is unacceptable for a 10 year old vehicle with average mileage that was properly maintained. I contacted both the dealership and manufacturer, and neither will accept any ownership in the matter, or provide assistance on repair costs.
Excessive oil consumption. One quart down every 1500 miles. First noticed Jan 5, 2018.
Car burns a quart of oil every 1000 miles which started at 150k. This is an ongoing problem that cant be fixed.
Toyota has excluded the Prius in advising their owner about excessive oil consumption but included the camry, corolla, seqoiua etc. It burns/not leaks 1 quart every 1,000miles. No warning light on the Prius just have to keep checking it. Dealer says no fix except eventually put in a new engine. On the Prius chat forum many people have noted the same problem with no assistance from Toyota.
Burning oil and clogged injectors at 90000 miles despite have all oil changes at prescribed intervals as advised by Toyota. An engine rebuild and injector replacement have been recommended. No satisfaction from Toyota despite known problem.
I have had my 2008 Prius since it was new and I have taken meticulous care of the vehicle with documentation to prove it. The vehicle is burning oil to the extent that I have to put a quart of oil in every 700 miles. My local dealership confirmed it is an issue with the vehicle but Toyota USA said they won't do anything about it because there "has not been enough complaints". However, the Toyota Prius chat website has numerous complaints about oil consumption. Toyota did an extended warranty for the corolla and camry but refuses to do anything for the Prius. Numerous attempts have been made with Toyota USA to correct this issue but they refuse to do so. They did say they corrected the issue in the newer models . . . But yet don't want to acknowledge that is it an issue! so, they corrected an issue that they currently don't acknowledge is an issue!! second to this issue is that the back window can only be closed by the driver's window button and will not close for the person sitting at that window in the back.
