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

I GOT INTO 2 ACCIDENTS IN 3 DAYS WHILE PARKING INTO OR OUT OF A PARKING SPACE. THE FIRST ACCIDENT 07/04/2020, MY CAR WAS PARKED IN A PARKING LOT. I PLACED THE CAR IN REVERSE AND SUDDENLY IT ACCELERATED AND THE BRAKES FAILED TO WORK. MY VEHICLE ONLY STOPPED AFTER CRASHING INTO THE CAR BEHIND ME. THE SECOND ACCIDENT HAPPEN 7/7/2020 WHILE PULLING FORWARD INTO A PARKING SPACE, THE CAR SUDDENLY ACCELERATED AND BRAKES FAILED TO WORK AGAIN. I CRASHED INTO A CEMENT POLE WHICH STOPPED MY VEHICLE. I COULDN'T FIGURE OUT WHY THESE 2 DANGEROUS ACCIDENTS OCCURRED? MY VEHICLE WAS JUST REPAIRED OVER A WEEK BC THE CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHT CAME ON. THE MECHANIC SAID THE PROBLEM WAS FROM A CATALYTIC CONVERTER THAT WAS CLOGGED, SO HE REPLACED IT WITH A NEW OEM PART. THE AIR CONDITIONER WAS BLOWING HOT ALSO, SO THE MECHANIC REPLACED THE AIR COMPRESSOR IN CAR AT THE SAME TIME. I WISH TO FILE A REPORT BASED ON THE "SUDDEN UNINTENDED ACCELERATION" DANGER.

WHEN COLD THE CV TRANSMISSION IN THE IQ WILL NOT ALLOW THE VEHICLE TO PULL AWAY UP A STEEP HILL. THIS HAS HAPPENED SEVERAL TIMES AND REPRESENTS A SERIOUS SAFETY CONCERN. THE ISSUE ONLY HAPPENS WHEN THE CAR IS COLD, IT WILL PULL THE SAME HILL WITH NO PROBLEM WHEN WARM. THE IQ HAS A CV TRANSMISSION AND IT FAILS TO ADJUST TO A HIGH ENOUGH RPM TO PULL AWAY UP A STEEP (10%) GRADE. THE PROBLEM MANIFESTS AS EITHER NO OR VERY SLOW FORWARD PROGRESS (LESS THAN WALKING SPEED) EVEN WITH THE ACCELERATOR HARD DOWN. THE DEALERSHIP SERVICE REP SEEMED UNCONCERNED ABOUT THE ISSUE. *TR
