Please tell me about these codes.
I’m not sure which interior light stays on since this is my sons car, however, he just had an oil change yesterday and he says the light still stays on. I will ask him today which light it is. Also, the steering wheel seems to pull while driving. He also has a muffer problem when he hit a pothole.
