Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My car consumes about two quarts of oil per 1000 miles. Mechanics have told me that it doesn't appear to be leaking, it could be being burned though. I keep my car running with frequent oil changes and go through a good amount of oil every month in between. Many other TC drivers have told me they have this same issue also.”
NHTSA complaint #10691005, filed 2015-02, 80,000 miles“I change my oil every 3000 or less miles with full synthetic amsoil 5w-20. I have to put in 1/2 a quart of oil for every gas fill up. I'm a highway driver that sets cruise control at 75. I don't dive crazy. 2007 has an extended warranty, where is the one for 2006?”
NHTSA complaint #11092673, filed 2018-05, 180,000 miles“This car is constantly burning oil. My oil pressure light never fails to turn on somewhere between 1000-2000 miles after each oil change, and I have to refill to stop the light from coming back on.”
NHTSA complaint #10936209, filed 2016-12, 100,000 miles“Oil consumption!!! I've owned my 2006 Scion TC for about 5 years and have recently been experiencing a huge oil consumption issue. It didn't phase me at first, although now I need to set my odometer to zero and refill my oil every 800 miles. I believe it is certain internal parts that are causing this problem, such as the pistons and the piston rings . I've noticed that this has been an ongoing problem for a lot of Scion TC's lately, which has been taken care of through an extended warranty program for the model years of 2007-2009. …”
NHTSA complaint #10884153, filed 2016-07, 110,000 miles“Engine has sever oil consumption to where we are adding a quart or more every 1000 miles or so in between oil changes. Worries me to were I check every week just to make sure there is enough oil. I should not have to worry about that sort of thing. While driving om streets or highways, happens every where, as you shift at a certain RPM (about 1500-2500-3000 ect) the car will hesitate for a few seconds. We originally thought it was from the A/C since I bought the car in the summer time but once the A/C is off the car still hesitates. …”
