2017 Hyundai Ioniq Hybrid: check engine light

Filed Aug 31, 2026 · Electrical, Transmission · GA · fire · 1 injury

I was driving my two young daughters (ages [XXX] and [XXX]) to school, in clear conditions, when we suddenly heard a static-like noise. Instantly, the car's check engine light and check EV battery light came on, and I realized I could no longer accelerate. I immediately pulled off to a safe shoulder and turned the car off and then back on. The car would not move. I exited the vehicle and THANKFULLY left my car door open. I walked around the vehicle and immediately called my husband for help. Within seconds, my [XXX] daughter, who was sitting directly behind me in the rear driver's seat, told me she saw smoke. I went to open her door and realized it was locked. My key fob and door lock would not unlock her door. I reached through my seat to open her door and instantly saw the smoke coming from a vent just to the left of her legs. I unbuckled her and pulled her out, and climbed through the vehicle to get my [XXX] unbuckled and safely out of the vehicle. I cannot stress enough how grateful I am that my car door was left open because I don't believe I would have been able to break the glass to get my daughters out. The could have easily died. Within a minute of the smoke starting from my daughter's vent, the flames began from the same vent. I got both daughters away from the vehicle asap. While trying to grab what I could from the vehicle, my fires on my right hand were caught in the fire. The vehicle became fully engulfed in fire and was a total loss. Two volunteer fire departments responded. I have both the fire incident report as well as the police incident report. The police report only mentioned one daughter but witnesses can attest that I had to get BOTH daughters out. Following the incident, I went to the doctor to receive care for my burns and received a chest x-ray due to smoke inhalation. My [XXX] daughter has been traumatized and keeps thinking something is wrong with her. She told me her bottom felt very warm just before I pulled her out.

As I was driving home from work, my vehicle jerked a couple of times and was speeding up and slowing down by itself. As I was driving the check engine light appeared and did not go away at all. Although, my car was accelerating and slowing down by itself, it was struggling to go past 20mph. When I got home and parked my car, I was unable to reverse my car, even though it was in reverse. Luckily, there was no one behind me or in front of me or else I'm sure there would've been a crash. On top of this, the car has only 1700miles on it and was barely 3months old and this problem appeared, I'm super disappointed and the company hasn't even told me what was wrong with the car yet.

Purchased vehicle on november 4th, 2017. It is now december 1st, 2017. Problems shortly followed after leaving dealer. Vehicle hesitates, shudders, and jerks while gas engine is engaged while in motion. Also, sometimes almost loses power while in motion using the gas engine. While running in EV mode, no issues or occurrences. Vehicle now has 1822 miles. Vehicle has been in the service department three times. No resolution for problem, as well as being misdiagnosed each time. Check engine light illuminates, diagnostic message reads "a problem has occurred with your engine control system." as well as "multiple conditions have occurred with your vehicle." hyundai service is aware that other vehicles have had similar issues, resulting in cylinder head being replaced. Hyundai service team has exhausted efforts to fix my vehicle without changing the actual cylinder head, which in turn, left me on the side of the road. Blue-link representatives were friendly, but forgetful of the task at hand. They have replaced my fuel injectors twice as well as oxygen sensor twice, each time saying the problem is "fixed." after second time in the shop, vehicle nearly died in the middle of a major roadway with me and would not exceed 35-40mph or accelerate safely. There are multiple people on online forums complaining of the same problem with the same misdiagnosing's. (faulty fuel injectors as well as bad oxygen sensor.) I just want to drive my brand new, hyundai ioniq hybrid, limited... But I cannot drive it safely or drive it at all when it is in the service departments hands. Have had these recurring issues 11/6/2017 - to present 12/01/17.
