“I was traveling to north carolina and pulled over to change my tire, my car would not start.leaving me stranded on the interstate. Again I arrived on north carolina and the will not start after staying at a friend's for the night. I cannot get back to connecticut. I researched and seen that this is an ongoing issue that is not being rectified.”
NHTSA complaint #11373602, filed 2020-11, 120,000 miles“My vehicle was running superior, no warning signals or straining when powering on. Parked car then an hour later tried turning vehicle on and will not turn on for any reason just radio worked. Found out it was steering module needed to be replaced for a hefty $1100. Had the car for only 3 months and barely used it. I believe it's a recall on these issues.”
NHTSA complaint #11115027, filed 2018-07, 73,000 miles“Steering wheel locked in garage. Remove key from ignition is message on instrument cluster. Car will not start. This car has less than 64k miles. Car was stationary in my garage. Now I have to pay a tow company to somehow get it out of garage, as it is front end in oriented (pulled in instead of backed in), and tow to dealership, and prepare for an overly inflated repair cost.”
NHTSA complaint #11183311, filed 2019-02, 63,690 miles“My right tail light keeps dimming and going back bright. I thought I needed a bulb but but it gave me a message today for everything on the right side but then the message went away. Last night someone told me the right light was dim then it got brighter. I've been smelling a faint burning smell but today it was kind of loud. I checked and it looks like the plastic and wire is melting on rte right tail light.”
NHTSA complaint #11172381, filed 2019-01, 119,700 miles“Came home parked the car and after 5 mins. Had to go somewhere try to start the car , no power at all , ignition wont start . Radio works , lights work remote key works opens and locks the doors . But will not start . And steering is locked also , I did a little research and found out a lot of people having the exact same issue. I believe it should be covered by recall .”
