“The paint of the body is defective”
“have a 2013 Scion IQ (auto/cvt). I had the 'check engine' and 'trac control' lights come on a few years ago.. I was driving on city streets. All I noticed was that the car didn't respond as it should when I gave it gas. ( nothing drastic ) I ran the codes. It said the gas pedal was the problem. I removed the pedal assembly. (it's easier to unplug it that way. I unplugged it and looked at the inside of the plug. All looked fine. Plugged the pedal back in and all was good then. (I'm sure I avoided a $500 bill ) Same problem just occurred a few years later. I didn't bother running the codes. I just unplugged/re-plugged the pedal. Saved another $500. Here's a scary one. I was driving the car the first light snow of the year. On a city street, going slow on level road. Just maintaining speed..... not slowing ..... not speeding up...... not turning. All of a sudden”
