2025 Hyundai Santa Fe Hybrid

Our car had 2149 miles on it. Engine started to stalled on [XXX] on [XXX] from OKC to Tulsa. We made it to Tulsa. The car was towed to Tulsa Hyundai dealership on 12/25/2024. After diagnostic on 12/26/24, we were told the car had bad gas. The dealership performed the necessary work including replacing 4 fuel injectors in order to fix the problem. It cost $3991.52 and it took a week. We were told since this was not a manufacturer problem that we are responsible for the repair. We paid for the repair. We always get our gas from Costco. So we filed a report with Costco stating that we got bad gas from them. Costco turned it into their adjuster at Gallagher Bassett. He investigated and told us that his findings indicated that Costco did not have bad gas in the month of December according to their quality reports. No other cars filed complaints regarding gas issue. Our claim was denied. The question remained where the bad gas came from. Was it truly a bad gas problem or did the car have fuel injector issues and that bad gas was a cover up. We bought a new car, we purchase gas from a reputable company and we ended up with this problem that we were responsible for through no fault of our own. We are filing a report to see whether there are other cars of this model that had similar issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

[XXX] - On re-entering the highway, after getting gas. accelerating slowly on ramp (passing 35-40 mph) - I crossed a patch of snow, the brakes locked up briefly! (Fraction of a second) I was about 2/3 up the ramp. No other vehicles near. 1000 miles on 2025 Sante Fe. Arriving home and searching on line I find others have experienced similar brake events on a range of Hyundai products. 29 degrees light snow, some slush, mostly clear road. Cruise control had been on prior to stop. I didn’t notice status during ‘event’ but noticed it was on when I was back on the highway. Lane keep and centering indicators on. Adaptive cruise was not on. No other events in the 20 miles home. No prior similar incidents INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When you stop the car , you cannot lock- unlock the car with keyfob. Nothing happens when you press these buttons on keyfob. And Media screen inside the car is still ON. But the car is OFF for sure. After few minutes only, keyfob works fine and you can lock-unlock, remote start etc. So for 5 minutes, you cannot do anything like locking the car, which is a safety hazard.

The contact stated that the vehicle independently accelerated, and the contact depressed the brake pedal and the vehicle responded as needed. The vehicle was not taken to an independent mechanic or dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 133,000.

Hi Hyundai- my 2025 Santa Fe calligraphy HEV, with around 900 miles wasn’t turning on and only able to start with a jump. After parking, it was unable to maintain a charge to start up again even after driving 1-2 hours. The dealer wasn’t sure why, replaced the 12v battery first and recharged it overnight. Unfortunately it also drained. Finally diagnosed that the hybrid starter generator needed replacing. More bad news, after replacing they discovered what the service manager said was a defective relay pack of some sort had fused. And the kicker is the part is unavailable until January. I am not sure how widespread or rampant this issue is, but I am concerned there might be more or further issues identified.
