2022 HYUNDAI SANTA FE Complaints

2022 Hyundai Santa Fe Plug-in Hybrid, confirming the exact symptom “the gasoline engine continues running after the vehicle is switched off.” the vehicle is on and your burn fuel and if the fuel tank is full then some major issue may occur.

The vehicle has suffered a catastrophic structural manufacturing defect involving a transmission case half seal failure. The transmission is actively seeping/leaking fluid directly from the factory-mated case assembly line seal. This presents a severe, progressive safety hazard. Transmission fluid leaking from the case half migrates along the underbody of the vehicle and directly coats hot exhaust and powertrain components during highway operation. This creates an immediate risk of under-hood smoke, thermal degradation, component stalling, or a potential vehicle fire at high speeds. Certified diagnostic inspection confirms this is a factory assembly defect (defective RTV sealant application or improper factory bolt torque) and not mechanical wear-and-tear or driver neglect. The vehicle currently has 88,000 miles, but the structural failure was first physically documented by a licensed facility at 59,870 miles. The manufacturer (Hyundai Motor America) has currently refused to honor the powertrain failure, forcing the vehicle to remain on the road with an active powertrain fluid leak risk.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while pulling out of the driveway and approaching a stop sign, the message "Check Transmission Oil Immediately" was momentarily displayed. The dealer was contacted and informed the contact that the vehicle could not be diagnosed unless the message was displayed. The contact stated that the failure recurred while driving approximately 35 MPH the following day, and the engine power was reduced. The check engine warning light was illuminated. The driver contacted Bluelink and was advised to pull over safely. Bluelink and the dealer advised the driver to tow the vehicle to the dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact associated the failure with NHTSA Campaign Number: 22V746000 (POWER TRAIN); however, the VIN was not included. The manufacturer was notified of the failure and offered to cover half the cost of the repair. The failure mileage was approximately 74,900.

This email serves as a formal dispute of the warranty denial issued by [Lester Glenn Hyundai Toms River NJ] regarding the Supplemental Restraint System (SRS) passenger airbag sensor in my 2022 Hyundai Santa Fe.The dealership has refused coverage, attributing the failure to "water damage." I strongly dispute this finding and am formally requesting a Corporate Goodwill Repair Exception or a tier-two engineering review of my vehicle due to the safety-critical nature of this component.

I did a navigation update as requested by the infotainment system on the Hyundai. After the update, the air conditioner would not turn on when the ac button was depressed . I took the vehicle to my local Hyundai dealer and they found the ac blower and ac button working intermittently. After further inspection, the mechanic found the multi fuses that sit on the PCB bloc had one burnt fuse that did not blow and was still hot and the PCB block had melted around where the fuse connected to it. ( Hyundai stated that they required the damaged PCB fuse, the PCB block and the harness). I'm concerned that the electrical short discovered by the Hyundai mechanic could have progress and burnt my car or my house since I keep my car in the garage. The Mechanic working for the Hyundai dealer found the burnt fuses and PCB block and kept them after replacing them with new parts. The ac was working fine until I did the navigation update and there were no warnings whatsoever.

The airbag sensor is on in the car. When I told the dealership they stated that the sensor is not covered under the warranty even though it was over by a fe hundred miles. None of the airbags will deploy if there is an accident. I don't see why a safety issue is not covered by the warranty. For the dealership to fix it, it is going to be over $800.

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.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while driving at various speeds, the automatic emergency braking system engaged while there were no objects or vehicles near the vehicle. Additionally, the contact stated that the pre-collision message was displayed while the vehicle was parked or was idling. The vehicle was taken to dealer on several occasions; however, the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was contacted and informed that the dealer assessment was most important. The failure mileage was unknown.

I have videos of these two incidents and others that I could not upload. While driving on the PA Turnpike at 4:25PM on 5/22/26 75 mph my accelerator pedal stopped responding, my front collision warning light, engine, EPB, and numerous other lights came on across my dashboard despite there being no contact with any object and my speed rapidly dropped. The front camera came on as if there was an object too close. I was in the middle lane. While I was trying to move to the shoulder there were tractor trailers behind me and to my right that began flashing their lights because my speed drastically dropped and was unable to safely stay with the flow of traffic in the heavy rain. While still in Drive car started changing through notices on my digital screen "Check Blind-Spot Safety system" "Check Forward Safety system" with the car crash icon, and "Check Driver Attention Warning (DAW) system." Then I began trying to press the accelerator pedal again and the car would not move at all but the tachometer was going to 2x1000rpm. When I turned the car off and turned it back on again the engine light was still on, but the accelerator pedal was responsive. About an hour later when the tow truck driver from AAA attempted to drive the car on to the flat bed the accelerator pedal was unresponsive again. This was at least the fifth time my vehicle had lost propulsion without warning. Every prior time Bowser Hyundai had different reasons for the failure, made a repair, and said it was safe to drive. Another incident occurred 4/7/2026 using cruise control at 84 mph when the car unexpectedly lost propulsion. The accelerator was again unresponsive, I was on the turnpike with two children in the vehicle. I steered towards the shoulder and the car slowed to a stop. After that incident, Bowser Hyundai replaced the transmission on the car. They notified me on June 18 that they believe they fixed the problem again but I don't feel the vehicle is safe for my family and worry it will be deadly

Child opened the back hatch (as instructed). The child then pressed the button to close the back hatch. Fingers were trapped at the bottom of the hatch, and the hatch “clamped” into position. The interior hatch release was not sufficiently intuitive for the chiller to remove the trim and slide the tab, resulting in the child being trapped for 10-15 minutes before help arrived.
