NHTSA Complaint #11479708 — 2021 HYUNDAI SANTA FE

This car since 6/7/22 has been plagued with issues where is starts cutting out and stalling followed by the check engine light coming on flashing. This has happened many times and just happens while driving down the road. It is a very dangerous condition as you can not predict when it's going to stall out. The car has been in the dealership 3X for this problem and spent over 40 days there. Hyundai replaced the fuel injectors claiming that was the problem. It was over 35 days to get the back ordered parts. They were replaced and the car seemed to be running OK. I drove it for about 150 miles and it ran like new. Then on 8/13/22 while driving in traffic on NH Highway US1, it started doing it again. I went into the Hyundai dealership since was right there. I brought the technician out and showing him my running car with the running car with blinking CEL. They pulled into into the shop and ran a scan on it. They said there was no active codes. I asked to leave the car with hem so it could be investigated and there response we "we don;t have a car for you until next Tuesday". I was forced to drive off in a confirmed dangerous car. I pulled out into traffic on US1 and the car immediately lost power and started cutting out and the CEL was back on and blinking. I turned around on the very next street, turned the car off and back on and the CEL cleared. I pulled back onto US 1 and the car immediately lost power and started cutting out and the CEL was back on and blinking again. This very nearly caused a 2nd accident as ad zero power to accelerate. My concern is Hyundai has no idea what the problem is. They know there is a dangerous problem. The service manager drove the car/confirmed himself there is a serious issue. My other concern is the Hyundai dealership knowingly sent me away in a car they had confirmed for themselves was unsafe nearly causing a accident on the highway. I had to speak with the General manager to get a loaner to leave my defective car.
