My concern is who is going to pay for the damage to my car? I initiated a claim with Hyundai due to my car malfunctioning at a stoplight, the light turned green and I gently pressed the accelerator and it lurched forward and smashed into the car in front of me. I had taken my car in multiple times telling them the accelerator sticks and hesitates. Each time they told me nothing was wrong with it. I researched online and I found many people were having this same issue with the accelerator in the 2017 Hyundai Tucson. I was also told there is a software update available to help with this. The service department at the Dealership said there is not one. I have an appointment with the Hyundai service department on 12/20, I need to know who is going to pay for my car.
