“Recurrent accelerator pedal failure (drive by wire) with check engine light warning. Occasionally, when accelerating, the check engine light comes on and the pedal depressing action initially has no effect for several depressions and then it works minimally. This may last for a while or for just a short period. It has happened several times. I did a search online and other people are having the same problem.”

“I was driving home from work when the battery light came on when I pulled into my drive way. I smelled something burning and there was smoke coming from under the hood of my 2007 Yaris. I popped the hood and the alternator was on fire. I poured water on it to put it out and disconnected the battery. It was still making an odd sound so I poured some more water on it and it started smoking again.”

“Passenger side of vehicle has a leak when the air conditioner is used. Took to the dealer and was charged approximately $200 to fix said problem. Less than a month later the issue is happening again. Seems to be more than one issue of this occuring.”
