The vehicle came to a complete stop filling cabin with smoke and wouldnt start in a bend on road blocking entrance ramp. Its available for inspection but at dealership. My safety was put at risk for collision as well as health with cabin filling with smoke. The dealer still has vehicle going on 3rd day without answers. The vehicle had warning come on for hybrid system failure appearing shortly before dying completely with smoke filling cabin.

I am submitting this formal safety complaint regarding a structural defect in my 2023 Hyundai Santa Fe Hybrid that I believe poses a safety concern and warrants federal investigation under the National Traffic and Motor Vehicle Safety Act (49 U.S.C. § 30101 et seq.). The vehicle exhibits a persistent and recurring structural creak originating from the pinch weld area adjacent to the hybrid battery storage compartment â specifically at a metal-on-metal contact point above the rear driver-side wheel well. The noise presents most prominently at low speeds over uneven surfaces, driveway transitions, and speed bumps. The root cause, as identified by service documentation and owner community…

Own a 2023 Hyundai Santa Fe Hybrid and have experienced the following issues over the past year and a half. Beginning after maybe 40,000 miles we pulled out onto a roadway and the engine immediately lost power and started flashing a glaring red warning that the hybrid system was failing and to pull over. We luckily were able to and turned the car off and waited. I tried to turn it on and it came back to life as if there was never an issue? We drove off. it left no warning code or did not update my Bluelink App. I took it to the dealership and they could not find any issues. Fast forward another 5 or 6 months and it happens again. Take it to the dealer and they keep it a week to go over it…

One two separate occasions while driving the car has lost the ability to accelerate. There is no acceleration power even when completely flooring the gas pedal. The dash displays a red circle warming that states "Check Hybrid system. Stop Safely". I have had to coast to the side of the road and then the car shuts off. It has taken several minutes before it can start again, and then displays a warning "Park with engine On to charge battery" before being able to shift the car into drive. I immediately took the vehicle to the dealership at which I had purchased the car. They have run a diagnostic on it and did not find any error codes stored in the computer. I picked up the vehicle from them…

On September 4, 2025 as I pulled on to Interstate I-70 my car suddenly lost power. Gas engine died. Loud attention sound started. Instrument cluster started flashing red with message "EV system failure, stop immediately" EV battery showed full depletion although a moment before it showed about 75% power. There was only enough propulsion to keep moving slowly. Since this was a construction zone the shoulder was blocked off and roadway was reduced to only one lane. I had no where to go. A large truck narrowly avoided rear ending me. I was scared and felt helpless. Eventually I was able to pull off and shut off the car. It was able to be re-started immediately with no warning indicators and EV…

I am reporting a serious and recurring safety defect with my 2023 Hyundai Santa Fe Hybrid, purchased new in January 2024. The vehicle has suffered from over 30â40 sudden hybrid system failures, including loss of acceleration, âStop Vehicleâ warnings, and check engine lights. These incidents happen without warning, including while driving at legal speeds (40â70 mph), on residential streets and highways. Most recently, the car failed twice in two days, while my teenage son was driving within all road laws, including once with a friend in the car. The vehicle simply stopped accelerating in the middle of traffic, endangering them and everyone around them. These failures have happened at…

We were driving in Montana down [XXX] and heard a very large âpopâ sound above us. Our vehicle was traveling alone in the area at the time, no other vehicles were around ours. There was no debris on the road or flying in air at the time, either. At this point the panoramic roof glass was closed but the interior cloth cover was open and there was no evidence of any damage. When we stopped for gas, the front glass panel covering behind the windshield and before the panoramic roof glass, was completely shattered. The weather was the same as it had been, 80F with minimal cloud coverage. There was no sudden change in weather/driving conditions.
