Filed Jul 8, 2026 · Electrical, Engine · GA · fire

Starter wiring burned and caused a small, localized fire in the engine compartment of the vehicle. Replacement of the starter assembly along with related engine wiring harness is necessary for vehicle operation. After mechanic review, it was determined the vehicle will catch fire upon attempt to start the vehicle. The vehicle was parked near our home when the internal burning and subsequent small fire started. The problem was reported to our nearest Hyundai dealership and the car was evaluated by the dealership to confirm the above. The car was inspected by Progressive insurance as well at the dealership and it was determined it was not included in TSB 24-01-057H recall for this VIN for the 2015 Hyundai Genesis. For this specific issue, there was zero indication this was a possibility.

My car has previously been reported for having issues with electrical problems that I have had to fight the manufacturer to get repaired unsuccessfully.I am constantly experiencing and smelling burning in my dash when I crank the car. Car is no longer under warranty, so therefore, I cannot afford to continue to go in and report the same problem over and over again.My turn signal bulbs are constantly blowing, and I'm having to replace them at a rate that is not normal.I'm sure this is all related.

So there are TWO main points of concern on this vehicle, number 1 being the steering racks. Many other people have had the same issue as myself. Steering rack completely shut down about a year ago on the freeway, rendering my steering completely useless which was extremely dangerous. 8K repair bill that Hyundai will not acknowledge. Now that comes to my 2ND point, the oil pressure sensor switch. It’s more common than the steering racks. Many owners are reporting it as low at 40-50K miles, yet there’s an open recall in Korea for this exact problem. But the USA does not get any acknowledgment for it??? Yet another costly repair due to defective engineering. Might I add as well, the transmissions Prior to 2018 no matter if you’ve had them replaced, they end up failing and people get absolutely 0 help with them. It’s ridiculous and these issue can eventually cost someone their life some day.

After Hyundai performed a recall service on my vehicle, the radiator hose burst while I was driving on the highway, causing the engine to fail completely. Smoke came from the engine compartment, and I had to pull over immediately with my family to avoid a serious accident. Before the recall, the vehicle had no issues and ran perfectly for three months after purchase. The problem occurred only a few days after the recall service, which included work on the ABS module. Hyundai refused to take responsibility, even though this failure happened right after the recall repair. The dealership and manufacturer did not inspect the vehicle properly and made their decision based only on a phone conversation. This is a severe safety concern because the engine failed suddenly on the highway. I believe this failure is directly related to the recall work performed under the federal safety agency Recall #21V160000, which is still listed as incomplete on the federal safety agency records.

I just purchased a 2015 Hyundai Genesis 3.8 4 door sedan 1/10/2025. Randomly lately the car does a slight jerk and the screen goes black, that happened about 5 times in just a few weeks. twice the car shutoff and back on at slow speed coming to a stop, and then entering into a parking lot. same day at 65-70 mph on the freeway it jerked hard and the engine turned off and on. Very scary and dangerous!! I did not see anything on recalls that would pertain to this happening. All recalls have been done on this car, that's what it indicated. Service guy wasn't sure. this is a random thing. I could leave my car with them but they'd have to drive it a lot for long periods before it might actually happen again.
