Hey guys, I was wondering if anyone might have some insight or experience with a problem that popped up last night. On my drive to class, the car throws a check engine light (solid, not flashing) and shortly after, throws a TRAC OFF message. The car is a 2016 IS300 AWD with just over 1k miles. The only "mod" is an Invidia axle back. I did some research and came up with anything from a VVT problem to a vacuum leak. Could it have something to do with the exhaust? I have a service appt tomorrow but I'm curious as to what this could be.

 

after your service appointment, let us know. without a code, it's just a guess

 

The car fired up fine this morning with no codes shown and out of limp mode. After all of that, it just turned out to be a batch of bad gas. The code was in correlation to an injector fault. The dealer said its nothing to worry about. Hope this helps someone in the future
