2018 Hyundai Santa Fe Problems

See attached letter for complaint

My wife was driving the vehicle by the left lane on route 9A northbound on elmsford at a speed around 35 mph. The vehicle suddenly came to stop completely while driving. My wife tried to start it but it didn't start. We called the police to come help us due to the ongoing traffic while the towing was on its way. Our mechanic told us the engine was seized and needs a replacement. The vehicle is a 2018 and has only 118000 miles. We do oil changes periodically every 3000 miles.

On April 13, 2026, I arrived home and parked the vehicle, engaging the traditional shifter into the "Park" position and turning off the engine. After exiting and standing on the ground to retrieve a purse from the cabin, the vehicle spontaneously and rapidly began reversing. ​As the vehicle gained momentum, I was struck by the driver-side door, which knocked me down and resulted in the vehicle running over me. The vehicle only stopped its rearward movement once it collided with a neighbor's parked car. Only after the vehicle began moving did the horn begin blaring, indicating a delayed rollaway alert. ​This incident resulted in a fractured ankle that required surgical intervention. Despite the traditional shifter being placed in "Park" and the engine being off, the vehicle failed to remain stationary, representing a catastrophic failure of the parking pawl or transmission engagement.

At 118,000 miles Downhill brake, transmission and 4 wheel drive were damaged from the hyundai dealership not fullfilling warranty. They disconnected my tow hitch and my transmission was burning .. smelled like a bon fire. Took me 1 year to repair and have transmission changed through warranty but they didnt change the other components that were damaged due to negligence from the hyundai dealership. The dealership was very rude and didnt dedication their attention or care to truly finding what was wrong with my vehicle.

In September 2024, my 2018 Hyundai Santa Fe experienced an unexpected engine lock-up while driving, creating an immediate safety hazard. Vehicle lost power, began smoking, and posed a potential fire risk. Fire department responded to prevent the engine from catching fire and had to spray the engine compartment with high-pressure water. Following this incident, vehicle remained in Hyundai’s possession for ~9 months for engine-related repairs. When we picked up the vehicle after the prolonged repair period, front-facing camera had completely stopped functioning. This camera has always worked prior to the engine lock-up and was functioning the day of the incident. This was reported to the dealership, Hyundai Motor America. A case manager (Nemesh) took the case. Very supportive, helpful and provided a thorough process for investigating the situation. However, all the sudden case was assigned a new case manager (Bryan) and the process immediately changed and the claim was denied. Given the timing and circumstances, the camera failure appears to be the result of electrical or component damage caused during the engine failure/fire-prevention event. The dealership also confirmed that no independent inspector ever assessed the vehicle for secondary damage despite my repeated requests. Hyundai later denied responsibility without conducting any physical inspection of the damage. This sequence of events — sudden engine failure, required fire-response intervention, prolonged repair, and subsequent electrical component failure — raises significant concerns about safety and the potential for related electrical or wiring issues caused by the engine incident. I am reporting this because the underlying engine failure and fire-risk conditions represent a serious safety defect, and related component failures may indicate broader issues with damage resulting from these events. Also Hyundai not letting the independent inspector assess gives me great concern something was missed.

I have noticed for the past year that my steering column feels loose. It makes a popping noise and really makes noise on rough pavement. I feel like the steering wheel is just gonna come off into my hands. It's very loose to turn and you can feel the pops within the steering wheel. I took my car to local repair shop and they told me there was a recall and that I should take to dealer. I called dealer but my Vin # is not listed within the actual recall. However I read the recall itself and that is what is happening to my Hyundai. It makes no sense that my exact Vin # would not be included in recall since I am having that problem.

I was driving going around 50 and put on my brakes after that the abs light Epb light and cruise control lights all came on and my car wouldnt stop unless I preessed very hard on brakes. and other lights on my dashboard came on then the next day I was driving to work and almost wrecked and my car wouldn't stop I had it towed in to cooks automotive and the seals had exploded on the master and cylinder and the booster.also the abs motor would not turn off and my cruise control went out I paid over 1300.00 to get my car fixed but the mechanic informed me that it should have not happened and there was a recall on my year hyundai. Now after almost paying and loosing a weeks worth of work because of malfunction in the vehicle.

I stepped on the brakes and all the aeb warning collision warning went on and I turn my car off and it still sounds like something is running

My airbag light came on 1000 miles over the warranty mileage while on vacation. Had the issue checked and it was a 'pre tensioner', driver side, that shorted out and in turn shorted out the airbag module. This is a huge safety problem and should not happen. It should also be covered, due to no fault of my own. I have tried to resolve the issue with Hyundai customer care, but no help from them. I had to, because I'm not driving unprotected, get the car fixed on my own. I'm retired, a veteran and on a fixed income. $2300.00 is a lot to absorb. I've asked Hyundai for help, but no response.

The contact owns a 2018 Hyundai Santa Fe. The contact stated that while driving at 30-35 MPH, the contact was rear-ended by another vehicle, hit on the driver's side by a truck, and rear-ended again; however, the air bags failed to deploy. The contact sustained injuries and received medical attention. A police report was filed. The vehicle was not deemed totaled. The vehicle was towed to the tow yard. The manufacturer was made aware of the failure. The approximate failure mileage was 42,000. The VIN was not available.

The oil pressure switch has a faulty seal causing oil to leak out onto the engine block. This causes oil on the underbody and ground, smoke amd smell from oil on got surfaces, knocking noises from the engine, reduced power or hesitation, illumination or the check engine light and oil pressure light, high speed stall, and will also cause fire in the engine compartment resulting in death or sever injury. I have taken my car to the Red McCombs Hyundai dealership in San Antonio TX for repair and they have confirmed that it is the oil pressure switch seal that failed. The oil leak has also damaged electrical components causing a malfunction in the dash cluster and steering wheel control.

Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: Two fuel injectors on bank 2 are failing intermittently causing the engine light to flash and stay on (P0300 errors) and the car loses power.  Q: How was your safety or the safety of others put at risk? A: Driving to Newark airport on [XXX] the car suddenly lost power and was quickly coming to a halt. LUCKILY I was was in the middle lane and was able to get to the shoulder without incident. This also happened to my daughter when she was in WA state, driving to work on the highway (the car was serviced but the fuel injectors were not replaced - see attached receipt). Q: Has the problem been reproduced or confirmed by a dealer or independent service center? A: Yes. An independent service center performed a injector value load test which determines the amount of blocked pressure the injector is performing under load. The values and the math show that more than 1 injector on bank 2 are failing. Q: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A: I had the vehicle in the Hyundai dealer but they did not do the injector load test and only wanted to replace all the coil packs and plugs. I had two other independent service facilities confirm the issue is with fault fuel injectors. Hyundai has the parts on hold and is not releasing any due to this issue. I do NOT understand how this is not a recall circumstance. I am fortunate that in both instances an accident did not occur. Q: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A: Yes, the engine light comes on - at first blinking, then steady.

The contact owns a 2018 Hyundai Santa Fe. The contact stated that while the vehicle was parked, the contact became aware that there were holes underneath the front driver’s and passenger’s side seats. The vehicle was taken to a dealer and the seats were removed; however, the seats were not replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 140,000.

THE DRIVER'S SEAT APPEARS TO BE SET TOO LOW AT THE BACK OF THE SEAT. THE SIDES OF WINGS OF THE BUCKET SEAT ARE TOO HIGH NEAR THE REAR OF THE SEAT. DUE TO THE POOR DESIGN IT CAUSES THE DRIVER TO POSITION THEMSELVES AWAY FROM THE LEFT SIDE WING EITHER FORWARD OR FORWARD AND TOWARDS THE CENTER CONSOLE. I WORRY THAT DUE TO THE POOR SEAT DESIGN SITTING PROPERLY POSITIONED WITHIN THE SEAT IS NOT POSSIBLE BECAUSE YOU CAN NOT SIT COMFORTABLY. IT APPEARS ONLINE THAT MANY COMPLAIN ABOUT THE DRIVER'S SEAT. DURING AN ACCIDENT I BELIEVE GREATER PERSONAL BODILY INJURY COULD OCCUR TO A DRIVER BECAUSE OF THE POOR SEAT DESIGN AND NOT BEING PROPERLY SEATED IN THE SEAT. I HAVE RIDDEN IN THE PASSENGER'S SEAT AND IT DOES NOT APPEAR TO HAVE THE SAME ISSUE. IT MIGHT BE THE OUTER PLASTIC SHROUD ON THE LEFT SIDE OF THE DRIVER'S SEAT THAT CAUSES THE IMPROPER SEATING WITHIN THE VEHICLE. I WORRY FOR MY SAFETY, MY FAMILY'S SAFETY AND OTHER DRIVER'S SAFETY BECAUSE OF THE POOR SEAT DESIGN.

DRIVING A RENTAL CAR AT 4:30 A.M. ON COUNTRY ROAD ATTEMPTING TO CATCH OUR FLIGHT BACK HOME. AFTER DRIVING APPROX. 20 MINUTES, HEADLIGHTS WENT OUT AND DASHBOARD LIGHTS. WE HAD NO VISIBILITY, ATTEMPTED TO STOP VEHICLE, LEFT PAVEMENT AND STRUCK A TREE. DURING OUR WEEK RENTAL OF THIS VEHICLE WE DID HAVE ISSUES WITH SUV LOSING POWER WHEN CLIMBING A HILL, BUT NOT A STEEP ONE AT ALL. SUV WOULD DROP AT LEAST 10 MPH WHEN DOING SO. NOT SURE IF THESE TWO ISSUES ARE RELATED AT ALL.

LED HEADLIGHTS PARTICULARLY ON UNLIGHTED ROADS PRESENT A DARKEN SHADOW ON THE TOP HALF OF THE WINDSHIELD WHILE CAR IS IN MOTION. NARROWING VIEW IS A SAFETY HAZARD AS ONE IS UNABLE TO SEE APPROACHING TRAFFIC OR PEDESTRIANS. DEALERSHIP AND HYUNDAI CUSTOMER SUPPORT STATED THAT HEADLIGHTS MEET SPECS. SERVICE MANAGER DROVE CAR AT NIGHT AND TOLD ME THAT HE SEES THE ISSUE BUT HAS NO FIX. HYUNDAI CUSTOMER SUPPORT SAID IT WAS NOT A WARRANTY ISSUE, BUT A DESIGN ISSUE AND I COULD MODIFY THE HEADLIGHTS AT MY EXPENSE AND BREAK THE WARRANTY. I WILL ATTACH A PICTURE AND CAN BRING THE VEHICLE TO AN INDEPENDENT AGENT TO VALIDATE.
