“My 2009 Toyota yaris experiences a loss of power, and has weird pedal habits whenever I use my radio/cd player/aux port. Other yaris owners are claiming that this is also happening to them. When I am using the radio/cd player or aux, the car is totally different. It is almost a safety hazard because the car acts differently.”
NHTSA complaint #10327814, filed 2010-04, 10,340 miles“My 2009 Toyota yaris needs to be placed upon the recent recalls with Toyota. My accelerator pedal is beginning to get harder to push down, my brakes are mushy and are sometimes hard to stop the vehicle, when I have my defrosters on, the car wants to keep going and braking is harder. My radio randomly switches to am radio when its off, or on a different station. This all sounds electrical, and I have taken it to the dealer twice and been told no problems. I have an appointment next week to have it looked at again. …”
