2022 Hyundai Santa Fe

While driving, my vehicle displayed “Shifter System Malfunction! Service Immediately.” Immediately after, I was unable to shift the vehicle from Drive into Park, Reverse, or Neutral. The only way to park the vehicle was to turn the engine off while it was still in Drive, restart it, and then shift into Park. This is an extreme safety hazard. A driver who cannot change gears can lose control of the situation during an emergency, be unable to safely park, reverse, or place the vehicle in neutral if needed. Having to shut the engine off while the transmission is still in Drive is unsafe and not how the vehicle is intended to operate. This issue first occurred around 45,000 miles while the vehicle was under warranty, but it temporarily resolved on its own. It has now returned in June 2026 at approximately 65,500 miles, after the warranty expired, and is happening repeatedly. After researching online, I found many Hyundai owners reporting the same “Shifter System Malfunction” with identical symptoms, indicating this may be a widespread defect. I request that NHTSA investigate this issue, as it poses a serious risk to driver and public safety.

Vehicle: 2022 Hyundai Santa Fe | Current Mileage: 140,000 Description of Safety Defect: While operating a 2022 Hyundai Santa Fe at speed, the vehicle suffered a sudden, complete, and catastrophic loss of motive power in the middle of a live, active roadway without any prior warning or dashboard indicator lights. The transmission abruptly dropped out of gear and the engine shut down entirely, trapping the driver and three young children in active traffic and creating an immediate, life-threatening highway safety hazard. The vehicle was towed to Sport Durst Hyundai in Durham, NC, where technicians confirmed a total internal transmission failure where the gears fail to engage. This exact mechanical failure mechanism directly mirrors the severe engineering defect detailed in NHTSA Campaign Number 22V746000 (Hyundai Safety Recall 236) for electric oil pump failures causing a sudden loss of drive power. Hyundai Motor America Corporate Case Management has issued a flat denial of all safety and goodwill repair coverage based strictly on the vehicle's 140,000 miles, claiming that mileage absolves them of product liability for a catastrophic drivetrain safety defect that endangered three young children. Furthermore, the franchise dealership is actively withholding the GDS diagnostic failure scan codes from the consumer, calling them "internal documents" to actively suppress federal evidence of this safety failure. Further, the authorized Hyundai dealership engaged in deceptive practices by refusing to put anything in writing, and refusing my request for any diagnostic information, including any report indicating diagnostic error codes, technician summary, etc.

Beginning on 04/17/2026, my vehicle began displaying multiple safety-related dashboard warnings simultaneously, accompanied by audible alerts. The warnings included the Forward Collision Safety System, Blind-Spot Monitoring, Electronic Parking Brake (EPB), Stability and Traction Control, Lane Keep Assist, and AUTO HOLD — all activating at the same time. These warnings reappeared on several occasions and were photographed with date and location data embedded in each image. My vehicle was brought to Burlington Hyundai dealership, where a repair order was opened and a loaner was provided. The car was returned without the issue being fixed. Within days, the same warnings reappeared and the situation worsened. On multiple occasions, the engine shut off completely and the transmission shifted into neutral on its own while my vehicle was being driven at approximately 20 to 40 mph. On at least one occasion, the parking brake engaged automatically without any input from the driver. A dashboard photo clearly documents the message "Engine Off! Shift to N, then start engine." These failures are a serious danger to everyone on the road. When the engine shuts off while driving, normal steering and braking ability is lost. When the parking brake engaged on its own, the car stopped abruptly with no warning. Any one of these incidents could have caused a serious accident or injury. My vehicle was returned to the dealership for a second repair visit and a second loaner was provided. The dealership confirmed via text that the car was still in the shop but never followed up with a diagnosis or timeline. When the dealership was called directly, no update was provided. As of 06/04/2026, my vehicle has been at the dealership for at least 30 days across two visits — 11 days for the first and at least 19 days for the second — with no confirmed root cause, no completed repair, and no clear communication.

This vehicle has experienced: • Multiple roadside breakdowns • Three fuel injector system failures • 2 complete transmission failures and replacements • Loss of propulsion • Fuel and chemical odor safety risks • A cumulative total of over 60 days out of service, currently at dealer since 4-15-26. SUMMARY OF SAFETY-RELATED FAILURES AND REPAIR HISTORY Incident #1 — May 20, 2022 (Mileage In: 4,899 | Mileage Out: 4,909) Vehicle broke down roadside in an unsafe, unlit area, requiring towing.

when vehicle accelerates from stopping position motor immediately increases rpm's from 700 to about 4,000 and increases and decreases with jerking motion. sometimes much difficulty controlling speed and controlling car when there are approaching vehicles. the transmission does not perform safely there is the same problem when passing other vehicles and travelling uphill , sometimes 50 to 75 mph. the selling dealer informed me this may be this transmission's way of learning how to accelerate.I don't believe this. I am [XXX] old, never a ticket with two safety classes in my first 30 years of driving heavy vehicles for my employer. the selling dealer was unable to completely reproduce problem. I have this problem when vehicle is first activated in the morning as I begin driving also. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Took my 22 Sante fe to the Hyundai dealership to have the blower motor checked since I have no air flow in my car. Dealership informed me that the engine harness needs replaced and that it melted the fuse box under the hood. So, I am not able to replace my blower motor at this time due to the melted fuse box. Dealership also advised that they have seen the same problem in multiple 22 Sante Fe. and that there is likely more with the same issue within the United States. I have been noticing a melting/hot smell in the car before the airflow quit and I took it to the dealership to be diagnosed.

Ever since I bought by car in 2022 brand new the car has been shaking when I press on the brakes going around 70 mph. I took the car multiple times to the dealership and all they do is resurface the rotos. One time they refused to even look at the car so I called corporate and they got the dealership to do the same thing as before. But still the car shakes. I called corporate and they said to take to dealership to once again get the rotos resurfaced (how many times are they planning to resurface the damn rotors?) I took to dealership because the car was saying it was overheating. They ended up changing the thermostat or something related to it. And I asked them to once again look at the rotors because of the issue. The guy came back and said “we didn’t look at your rotors but you need brakes and that’s $500”. They refused to guarantee me if doing the break job will fix my issue. And I’m fed up. I looked online and as it turns out, the Santa Fe’s have a lot of possible manufacture defects. Such as: -Breaking System (Shudder / Vibration Common Issue) -Cooling System (Common Failures) - Suspension & Steering Components -AWD / Drivetrain (If AWD) -Electronics & Software - TSB (Technical Service Bulletin) Audit - Turbo oil-supply pipe crack / oil leak risk -Fuel-system pipe / fuel-rail hose leak (on certain turbo models -Transmission oil-pump / transmission-system recall (power-train issues) -Rear-view / backup-camera defect (visibility / electronics issue) (this actually did happen to me and they fixed it, but they denied it was a recall when I asked if this was common. So they lied) -Trailer-hitch wiring harness fire-risk recall And possibly more issues I’ve yet to come across other owners having. These are pretty serious issues. Some causing even the car to catch fire. This is extremely worrisome and I need peace of mind. Please help me out Thank you for your time
