NHTSA Complaint #11452085 — 2017 HYUNDAI ELANTRA

In June 2021 (41600 miles), my car cut off 3 times without service engine light coming on. When I stopped at lights and/or idle, the shuts off without warning. This is extremely dangerous for anyone on the highway or at traffic lights. The reason for the car shutting down is that the car's cylinder 2 misfired. I had to take my car twice, just for the dealership to say nothing is wrong with my car. I had to use my T-Mobile Sync Up to get the code and relay that message to the dealership. They would not fix it until I had a code. (What if I didn't have the Sync Up in my car to diagnose the problem. Once the dealership had the code, then the cylinder 2 ignition coil was replaced. I have an invoice. In February 2022 (44000 miles), the same thing happened at traffic lights and when my car was about to stop for parking. No advance "check service light" came on. The car just shuts off. This time T-Mobile Sync Up states that it was cylinder 4 misfired. But, when I took it to the dealership, they say nothing is wrong. They don't believe me unless it is in the car's system's history. But, T-Mobile Sync Up determined the problem before the dealership can find it. I don't have an invoice yet of the problem. This is a safety hazard and I spoke with a representative at my dealership and she stated that a lot of vehicles were having this safety issue. Someone could of ran in back of me. It's a good thing I didn't have kids in the car!! All of the cylinders' ignition coils need to be RECALLED. THIS IS A MAJOR SAFETY ISSUE!!!
