What 2006 Scion TC owners say
Most recent owner complaints, unedited.
Excessive oil consumption between oil changes, I need to check the level every month and add oil if needed. When I turn on the vehicle, the radio turns on alone or turns itself off, without pressing the button. These 2 complaints have been going on for more than two years.
Oil consumption
Engine block bolts are attached to an aluminum body of the engine causing bolts to become loose with time and can not rethread. Causing coolant to leak from bolt area
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?
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.
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. I'm trying to prove that issue is also affecting the 2006 model year too, and would greatly appreciate it if I could receive some help concerning this issue. I will upload a photo of an old piston that shows this exact problem.
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. We have noticed we are not the only ones with this issues but we are the only year that is reporting them. What is going on with my engine and fuel system?! Please help!!!!

Leaking engine coolant from back of cylinder head. Took car in to have head gasket changed was told the gasket was not the problem. The problem was the engine block that the threads in the engine block were stripped. Was told by toyota that it was a big problem and it would cost between 1500-1700 to fix the head bolt threads. Consider the number of cars trucks and suvs with this engine there should be a recall or some type of owner assistance for this problem.
