2024 Hyundai Tucson

I have a 2024 Hyundai Tuscon SLE that I purchased new and several months ago there was a recall on the trailer hitch wiring. I took the car to Hyundai and they removed the wiring harness hitch due to a fire danager. Todate I have not received a replacement hiring harness, so my vehicle is now useless for pulling a trailer for several months. (The spring and summer months are when I use this the most and have not been able to.) All I hear from Hyundai is that they do not have a cure for this. I notice that the 2025 and 2026 models have a wiring harness on them that do not need replacing. I need something done ASAP regarding this matter. Why has NOTHING been done regarding this replacement? It has been MUCH TOO LONG! Is there ANYONE at your organization that can help me with this matter ASAP!!!! Thank you.

The air conditioning system in my 2024 Hyundai Tucson has never adequately cooled the cabin during high outdoor temperatures, since I purchased the vehicle. The vehicle is parked outdoors in direct sunlight daily, as I have no garage or carport access, and the issue is most severe and consistent during hot weather. This creates a heat exposure risk while driving, particularly on hot days when cabin temperatures remain uncomfortably high despite the AC running and set to the coldest setting. Prolonged exposure to excessive cabin heat can pose a safety risk, including impaired driver alertness and general heat-related discomfort/health risk. I brought the vehicle to CMA's Hyundai of Lynchburg on July 9, 2025 to report this issue; the dealership found no fault and stated the AC was working correctly. I brought the vehicle in again on August 11, 2026 with the same complaint; the dealership again reported the AC was blowing air at the correct temperature, with no fault identified. The vehicle has been inspected and is available for further inspection upon request. There were no dashboard warning lights or messages associated with this issue. The problem has been consistent since I've owned the vehicle, and is worse specifically in hot weather.

On 7/29/2026, the vehicle experienced a critical safety failure involving the electronic transmission shift-by-wire system, resulting in an unintended rollaway after the ignition was turned off. While parked on an incline, the driver depressed the brake pedal and pressed the Engine Start/Stop button while the vehicle was still positioned in Drive (D). The engine shut off completely. According to factory safety design and vehicle specifications, cutting the ignition in this state is engineered to automatically trigger an electronic command to shift the transmission into Park (P). However, the vehicle failed to execute this electronic fail-safe. The electronic parking pawl did not engage, and the vehicle effectively defaulted into an un-geared Neutral state. Upon the driver releasing the brake pedal, the unanchored vehicle immediately rolled down the incline with the engine completely powered off. No audible warning chimes or dashboard fault lights were activated prior to or during the event to alert the driver that the transmission had failed to secure the vehicle.

This has happened twice now. When going at a low speed, once in traffic, once while performing a U-turn, while braking, the car is trying to accelerate. I have to practically stand on the brake pedal to avoid the car lurching forward. I saw no warning lights on the dashboard. I haven't yet brought the vehicle to a dealer or service center, but it will be.

Center rear buckle fails to latch. Plastic case separated after normal operation of closing/folding down the rear seat. Buckle case separated from buckle latch. Buckle would latch with plastic cover missing, however would be a considerable risk, as a the retaining bar feature is not captive to the buckle and would separate in use, if used. As well as a pinch hazard. The center buckle was only use a handful of times and is free from contamination/debris. A safety buckle shouldn't fail under normal operation of folding a seat as designed. The seat folding action caused the buckle casing to pop off and separate.

Some Palisade (LX2), Tucson (NX4), and Tucson Hybrid (NX4 HEV) vehicles may experience battery drain due to continuous operation of the cooling fan after vehicle ignition has been turned off, potentially resulting in a no-start condition. The continuous cooling fan operation is caused by a stuck relay in the engine room PCB block. This bulletin provides instructions to replace the engine room PCB block to ensure the proper operation of the cooling fan.
