2022 Hyundai Santa Fe

The horns stopped working, and this is a safety item since it’s the only way to notify another vehicle or pedestrian if they will be hit by my car. Another day, a car came out of the parking lot and almost hit my car. I was only able to avoid that accident because I reversed quickly. I took my car to the dealership, and it was confirmed that the horns are not working. To fix this issue, I need to replace them. But since my car is out of warranty, I will need to pay for this service. On 07/14/2025, I called Hyundai (Case number 4117-7538) to request the application of an extended warranty that they started to offer for the 2021-2025 model year Elantra (Z03). Since my car is the 2022 model year Santa Fe, they did not accept my request. I noticed that on several websites, Hyundai car owners are complaining about their car horns. Just the fact that Hyundai started to provide an extended warranty for a different model, but in the same year range as my car, confirms that they are having issues with this part. I just know about this extended warranty because I also have an 2024 elantra hybrid, that is covered by it (as you can see on the uploaded letter).

The Vehicle Trim is "Calligraphy" which comes with an 8 Speed Dual Clutch Transmission. This Transmission is Faulty and i already swapped 4 Transmissions under warranty under 55k Miles. (3 refurbished last one Brand new all having same issue) The Manufacturer *does not* want to admit that this is a Manufacturing Defect. (i opened a ticket #[XXX] with Hyundai Corporate office) The Vehicle surges forward when in "Park" which should not happen and I'm afraid it might result in a bigger risk. There are no fault codes or errors. It is a documented issue with multiple owners and discussed on Forums. This issue is unique to this manufacturer as no other DCT's (some of witch i owned in the past) experience such an issue (as far as i know).

A few days before the complete engine failure the car became very jerky on the throttle response I would slowly add throttle and the car would jump all over the place with RPMs and felt extremely jerky when shifting gears. At one point the engine downshifted past redline when decelerating off the highway. The day of the engine failure I was accelerating up hill after leaving a stop sign. Around 25 mph the throttle stopped responding and the engine went to idle around 800 rpm. The car started violently shaking and sounding like it was running on 3 cylinders. I tried the throttle again and nothing happened. At this time I was slowing to a stop on the hill while still in lane being unable to get out of lane to the shoulder. Upon coming to a stop the vehicle continued to shake and eventually the engine stalled while keeping the electric on. At this point there was never any lights on the dash board to indicate a fault. Upon attempting to restart the engine it turned over 3 times and eventually started all while violating shaking and eventually stalling again. The third time attempting to start it did not turn over. At this point I was stuck in lane and needed to call the police to come and assist me because I was unable to move the vehicle under its own power putting my life in danger. Upon taking getting it towed to a dealership they said it was a fuel injector fault.

The contact owns a 2022 Hyundai Santa Fe. The contact received notification of NHTSA Campaign Number: 24V879000(Back Over Prevention); however, the part to do the repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The contact had not experienced a failure. Parts distribution disconnect.

Description of problem: The Transmission will disengage while driving, allowing the car to 'coast' as if in neutral. The problem sometimes occurs at red lights, where the vehicle remains stationary for a brief period and then corrects itself as if nothing happened. I noticed the "D" character flashing on the dashboard when the issue occurred, indicating a problem. The engine will rev, but the car will not move. The vehicle spent about two weeks at the dealership (Hyundai of New Port Richie, FL), but they were unable to find an issue after conducting over 80 miles of test driving. The last incident occurred on June 8, 2025, only days after I had removed the vehicle from the repair shop due to this problem. When pulling into my son's driveway, the car's engine revved to about three thousand RPM, and the vehicle rolled backward, out of his driveway, and into crossing traffic. Luckily, the pickup truck on the street was able to stop before hitting my vehicle, which was now sitting in his lane of traffic. I looked down at the dashboard, and the car was still in "D" but would not move forward. After a few seconds, the transmission re-engaged and moved forward again as if nothing had happened. I DID NOTHING AND THE CAR RECOVERED BY ITSELF! I returned the vehicle to the dealership for further investigation on June 9, 2025, and am driving a rental. Summary: This car is unpredictable and unsafe in this condition. Someone could drive this car for days without experiencing an issue, but it does happen when you least expect it! I use this vehicle for local travel only, about twenty-mile trips.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while her son was driving 20 MPH, the vehicle failed to accelerate as needed. An unknown warning light was illuminated. The vehicle was towed to the dealer, who determined that the fuel injectors needed to be replaced, but the parts were on backorder. The vehicle was then towed to a second dealer, AutoNation Hyundai Mall of Georgia (3445 Buford Dr, Buford, GA 30519), who determined that the fuel injectors needed to be replaced and informed the contact that parts were still on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

While driving the car keeps Jenkins, and on the dash board it cane up have your power train checked. My vehicle has been in the shop 4 times since February over 30 days twice. My vehicle is still currently in the shop at the dealership. They refuse to check my power train area, and keep telling me 2 of the cylinders are backfiring
