NHTSA complaint #11065510, filed 2018-01, 60 miles“I bought the car used from a scam dealership. I had no idea that there was an engine recall in january until it turned off and on just one week after leaving the lot. I brought it back to them, obviously, they said it wasn't their problem. I then took it to college park Hyundai to have them update the knock sensor and diagnose the issue. After an extended road test, it was decided that my problem was an isolated incident. Yet I took it to other dealerships, and pretty much everyone says the same. …”
