    I went to start my car and it would not turn over. All the lights were on, the vehicle wouldn't move out of park, and the security system kept going off. The last time this happened I had the starter replaced and the neutral safety switch and it was fine for a bit but now it's happened again. This is at least the 3rd time I've had this issue. Please help! I know I'm not the only one. I had to have AAA come and pick my car up and bring it to a garage.

    A while ago the airbag light starting coming on intermittently and I originally thought it was the sensor detecting weight in the passenger seat or not and perhaps the sensor was a little off but did not investigate. Over time the light become on constantly but I didn't notice this shift until the horn stopped working recently too. After some troubleshooting of the fuse and relay, an independent shop determined that the clock spring is the issue. After researching online I…

    I complied with Hyundai's voluntary recall of my 2012 Elantra, supposedly designed to deter theft with some sort of software update. Four weeks after this, four teenager rolled up to my house in a stolen Hyundai Sonata. One of them jumped out of the car, smashed my car's back window, and stole my car. This whole process took place in broad daylight, in front of multiple witnesses, over approximately 30 seconds. I contend that Hyundai's "voluntary recall" was 1) fraudulent,…

Since the week of Thanksgiving 2022, I've had several instances of my vehicle stalling without warning before engaging the transmission; for example, my car once stopped moving completely on the freeway while entering the onramp at 55 mph. Since then, the problem has only gotten worse, stalling up to seven or nine times per week. Because of…

    I received notice of Safety Recall Number 193 from Hyundai Motor America. I contacted the service department at 2 local dealerships - Hyundai Fairfax and Hyundai Springfield - about a month ago to try to schedule this preventive maintenance but neither location replied to my inquiry. I don't know if recalls are optional for dealerships but I don't know what else to do. I was informed in an online chat that I could submit this dealership complaint through your website. I hope…
