2021 Hyundai Santa Fe

I was about to turn into a 2 lane road and a warning came on my dash, "shifter system malfunction service immediately " my vehicle was in Drive I was unable to move my vehicle, unable to shift into any other gear. It was sudden with no warning or loss of power prior to the warning and loss of movement.

When I try to open the fuel cover it wont' open. I have to lock and unlock my car, sometimes up to 10 times, to get the fuel fill door to open. This eventually is going to leave me stranded somewhere stranded. Some of my same year and model are covered under recall for this issue by when I call Hyundai my VIN is not covered. I would like it to be covered and repaired.

My horn stopped working. Not under warranty but I believe it is a safety issue. A replacement horn is not available and not under warranty. Online search revealed this is a common issue

Replaced horns a couple times, after doing research, this seems to be a deeper and ongoing issues with this car ok a larger scale. Horns die out or stop completely, causing multiple replacements.

The dealership I bought it from (Vineland Hyundai) I have had trouble with before where they say they fix things and they don’t. Last year there was a recall for the back camera not working. I took it in and supposedly they fixed it. Well, a few months later, the camera does not work at all and the problem issues with it is exactly what the recall says. I contacted the Better Business Bureau and the dealership and even though they have it in the system as completed clearly it was not done or it would not done correctly and right now I have no back camera. They refuse to help. I seriously doubt this was done at all being I’ve had issues with service said they did things before and did not. I even asked Hyundai if I could get this done at a different dealership that is more trustworthy and they refuse to help. I’m hoping you may be able to intervene and have them actually do this recall correctly.

-shift lever in transmutation stopped working so car would go into auto shut off and then would not drive once I took my foot off the break. Would not switch gears or drive. Had to shut car off then turn back on to get it to switch gears. -safety was put at risk majorly. Car did that in 5 lanes of traffic with me and kids in car and couldn’t drive. We almost got hit. -dealership said no issues found until I took it in a second time for the same issue then they said it was the translation shift leaver. -Briggs Kia inspected it -no warnings at all -This happened MULTIPLE times. Put the most current date

Vehicle has now had several incidences of completing losing all acceleration power while driving at both high and low speeds, resulting in need to turn on hazards and abruptly pull to side of road. Pushing on gas pedal does nothing and vehicle will even roll backwards if I pull over on a hill and take my foot off the brake. I have to put vehicle in park and turn off. Sometimes I have to restart the vehicle a few times before it will drive forward after putting it back into drive. The vehicle does not lose electrical power and will sometimes display the master warning light on dashboard and other times have no dashboard indicator of a problem. This is an extremely dangerous situation and my VIN is not listed under safety recall 22V-746 despite exhibiting the same behavior. I have contacted my local Hyundai dealership service in past and they recommended a transmission flush which did nothing to alleviate the issue. It is now happening frequently so we are reaching out to the local Hyundai dealer service center again.

Horns stopped working entirely. Car was crossing into my lane and I attempted to honk horn and no sound. No warning lights or messages on dash. Is available for inspection. No inspections conducted currently.

Was coming off an exit on the interstate and started slowing down. My brakes act like they didn’t want to work. Grinding and the pedal was twitching under my foot. The car stopped thankfully, but then all Linda of lights came on the my dash and will not go off. And 3 warning come up!

Horn stopped working due to the same issue other Hyundai horns stopped working.

The contact owns a 2021 Hyundai Santa Fe. The contact stated that while driving approximately 20 MPH, the vehicle experienced hard shifting while attempting to change gears, and the vehicle hesitated, and the check engine warning light illuminated. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired; however, DTC: P1C2D03 was retrieved. The vehicle was then taken to a dealer, where the same diagnostic trouble code was confirmed. The dealer diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 99,700.

Car misfiring symptoms like rough or shaky idle, hesitation and loss of power during acceleration, stumbling, unusual popping/backfiring noises, poor fuel economy, and a lit Check Engine Light. Felt vibrations / heard sputtering sounds, as if the engine skipped a beat, often becoming more noticeable under load or when accelerating. Sometimes, the issue goes away after restarting the engine.

On 1/1/26 while traveling on the highway with no traffic in front of or right of my vehicle the ADAS emergency brakes applied themselves and slowed the vehicle nearly causing my vehicle to be rear ended. Vehicle is available for inspection. Faulty assistance nearly caused a rear end collision along the highway. Not aware of ADAS being tested inspected although multi-point inspection was done 10/2025. No warnings prior to incident.

Horns assemblies are Failing repeatedly. Since ownership of the vehicle (2023 and a CPO Platinum Wrap), I have had to replace a single horn, or both horns three times with local Hyundai dealerships. mostly the right horn would fail, then the left. I am currently making efforts to have my vehicle’s horns serviced for the fourth time as they are not working. I have been to my dealership on Dec 16, 2025 & Jan 15, 2026, to have the horns repair to no avail. In December, a diagnosis was performed with no action. Yesterday, one part (horn) was not available, and I was quoted a fee of $400 to perform the task. This is extremely concerning as this is not a consumable part or fluid. This is a required vehicle safety item. There are TSB's for other models in the Hyundai line with similar failure of horns ( TSB's: 24-BE-018H & 25-BE-005H). These failures have not been covered under the Santa Fe line or the other remaining Hyundai models of similar years of production and experiencing like failures of horn assemblies as of this date.

Code P1C2D03 is popping up on my 2021 Hyundai Santa Fe after the dealership "fixed" the recall in 2023. My car is going into limp mode, failing while driving, and unsafe. Dealership and corporate won't help me. The transmission was never replaced with the recall and they are claiming they aren't relatable and can't do anything unless a recall is reopened.

My transmission failed, even after the #236 recall in 2022. My car was recalled for Recall #236 in 2022. My car was updated and "fixed" and now in 2025 is showing the p1c2d03 code and requiring a new transmission. The same recall, without the fix.The car is in great health and never had issues until I was going 60 miles per hour on a busy highway and it reduced to 26 miles per hour during busy traffic. Causing me to almost get rear-ended multiple times and people swerving off the highway to miss me. My car was not going, even with the gas pedal down. I had no warnings, it happened out of nowhere.

While traveling Interstate 75in Florida en route to Venice Hyundai for routine oil change at 65 mph, vehicle rapidly slowed to 40mph, driver pressing on gas pedal but vehicle would not accelerate( while being tailgated by semi that was flashing warning headlights at me). There was burning smell while this was happening. Pulled onto shoulder and called Hyundai service for assistance tow truck brought me in. Vehicle inspected by Hyundai Venice technicians ran through computer tests all ok, tech drove vehicle not able to reproduce problem. Oil changed tired rotated. Instructions included not able to do any repair because cannot find anything wrong with vehicle please contact us if problem recurs. I have had several conversations with service advisor voicing serious safety concerns regarding driving this vehicle and informing him that what occurred was my car went into failsafe/limp home mode which is what happens when there is serious problems with vehicle and should not be driven till repaired. And cannot repair until computer finds a code signifying problem.

The contact owns a 2021 Hyundai Santa Fe. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 24V879000 (BACK OVER PREVENTION), but the failure occurred. The contact stated that the back over prevention camera displayed a distorted image or a black screen occasionally while the vehicle was in reverse(R). The failure obstructed the driver's visibility, which prevented the driver from safely operating the vehicle. The dealer was contacted, and the contact was informed that there was no record that the vehicle had been taken to the dealer. The contact found the paperwork provided by the dealer when the recall repair was completed. The vehicle was not taken to the dealer or an independent mechanic for the most recent failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 50,667.

For a few month now the light of ABS have been turning on. At the beginning there was no diagnosis specific, cause kept turning off. Two or three months ago again turn on and gave code of back caliper on the left and was changed. An now yesterday August 5, 2025 the diagnosis its need of change of the SBS module whole.

The horn on my 2021 Hyundai Santa Fe has completely stopped working. This is a severe safety hazard. I recently attempted to warn another driver who was drifting into my lane but was unable to, forcing me to swerve and nearly resulting in a head-on collision. The horn failed without any warning. After researching online, I have found that this appears to be a known issue with the Santa Fe model and Hyundai vehicles in general. I am requesting a diagnostic and repair as this is a safety feature failure that could lead to a serious accident. Please let me know if this issue qualifies for a recall. Thank You
