Example complaints

“Engine dash lights ABS, traction control and engine light came on then off then back on will in motion. Also while in motion, an RPM surge occurred which almost caused me to rear end the car in front of me. This surge has occurred twice in the last day so have parked the vehicle for fear of having an accident that could result in bodily harm.”
NHTSA complaint #11056333, filed 2017-12, 59,000 miles“All the electronics in my steering wheel went out, the horn stopped working, and my airbag no longer works. Some of my warning lights on the dash even stopped working. The fm/am radio also no longer works. I took it to the dealership and they said my clock springs went out. I am very worried about my airbag not deploying in a crash. None of these work, whether the car is moving or stationary.”
NHTSA complaint #11256551, filed 2019-09, 75,000 miles“Driving home every light on my dash started blinking, no RPM, no speedometer. Blinkers did not work. When I turned into my driveway, parked and I turned the key but Jeep did not turn off. I was able to take my key out and the Jeep stayed running for a minute then turned off. Jeep would not restart.”
NHTSA complaint #11287737, filed 2019-12, 141,000 miles“My vehicle clock spring has gone out. My vehicle has 45000 miles and is a model year 2012. Other years, specifically 2008-2011 have been recalled for the very same thing. Also 2012 rhd models have been recalled for the very thing. My airbag light chimes and is illuminated when driving the vehicle, whenever I turn left, right or stop or accelerate.”
NHTSA complaint #10927471, filed 2016-11, 45,000 miles“The tipm unit went out, causing lots of issues. The issues we're aware of are: the doors wouldn't lock, shifter was stuck in park, radio/cd/bluetooth wouldn't work, and the front headlights wouldn't turn off leading to a complete drain of the battery. Thankfully, the vehicle was parked and this didn't happen while we were driving it (it could have been very dangerous if it did). …”
