Example complaints

“Reduced engine power light comes on intermintently while driving had the throttle body and accelerator pedal replcaed twice after I bought the car with 75000 miles on it. Still the reduced engine power light comes on. Just yesterday I was unable to start my car. Throttle problems light came on in window”
NHTSA complaint #11233963, filed 2019-07, 130,000 miles“Two different outcomes but stem from the same issue. While trying to start my vehicle I get a click and care won't start at all. Sometimes after several tries it does fire up. Also when it does start it will sometimes stall. Most recently while traveling didn't the interstate it stalled going 75mph leaving me to coast and disrupt 4 lanes of traffic.”
NHTSA complaint #10891806, filed 2016-07, 105,000 miles“Rear door locks, defrost, trunk lid stopped working. Noticed smoke on my passenger side while driving in town. I took it in and was shown that it melted the wires together and melted the rear body harness connector. ( I kept the part if needed) this is a danger to drivers. The fire can start at any time while driving! I believe this should be a recall. After researching I see this is happening to many of these cars.”
NHTSA complaint #11256486, filed 2019-09, 160,000 miles“While wife was driving at normal speed car went into limp mode many times over last few months causing accelerator pedal sensor codes.we have since changed this pedal sensor 6 times and same issue and codes pop up. We also changed throttle body w sensor and connector pigtail.I think there is corrosion in ECM and all these items have failed. These items should have been recalled as manufacturer defects in my opinion.we are still having problems same codes and im not the only one!”
NHTSA complaint #11395348, filed 2021-02, 120,000 miles“I have been having a problem with the AC vent trying to close when I shut off the car. It makes a loud sputtering clunking sound after the car shuts off. I was told it is the vent trying to close and would have to replace a motor for $2-300 plus labor. Anytime I start the car up, it makes a high pitch squealing sound under the hood and stops when I back out of park.”
