2024 Hyundai Tucson problems

EXTERIOR LIGHTING

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.

ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM

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.

VEHICLE SPEED CONTROL

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.

SEAT BELTS

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.

TRAILER HITCHES

The contact stated that the vehicle was taken to the dealer for repairs unrelated to a recall but recall repairs were completed unbeknownst to the contact for NHTSA Campaign Number 25V893000 (Trailer Hitches). The dealer removed the wiring harness which rendered the tow hitch inoperable. The manufacturer was notified of the issue and informed the contact that the removal of the wiring harness was the fix for the recall repair. The contact stated that he purchased the specific XRT model due to the specific feature of the tow hitch and now it is inoperable. The approximate failure mileage was 49200

VISIBILITY/WIPER

On Wednesday, May 13, 2026, I turned off the highway and came to a stoplight. While preparing to accelerate as the stoplight turned green, I heard what sounded like a gunshot and saw that my entire rear window had spontaneously shattered. There was no external impact which caused this to occur. I have photos of the incident. Although my one year old son was not in his rear facing car seat at the time, if he had been, he would have been at risk of injury due to glass fragments. I was at risk as the sound startled me into breaking when I should have been accelerating with the rest of traffic and it left my interior exposed to the elements. I am scheduled with Safelite repairs through my insurance company to repair the window on Monday, May 18th. There were absolutely no messages or any symptoms prior to the spontaneous shattering of my window. After researching, according to Chimicles Schwartz Kriner & Donaldson-Smith LLP, there is currently an investigation for a potential class action lawsuit regarding an alleged defect of my make and model causing spontaneous rear window shattering.

TRAILER HITCHES

Hyundai Recall 290 was performed on my vehicle by an authorized dealer. Because Hyundai has not manufactured or supplied the necessary extension cable connecting the new module to the hitch, the remedy is incomplete, and my factory-purchased towing equipment is now entirely inoperable. The Dealer has stated "CAMPAIGN COMPLETE" and has no plans to get the necessary cable.

VEHICLE SPEED CONTROL

The Manual Speed Limit Assist, or MSLA, feature unintendedly activated while I was driving, nearly causing a collision. I was initially unable to deactivate this steering-wheel based feature, as: (1) I did not intentionally press any buttons to activate it, and: (2) I had to balance the need to visually monitor other vehicles on the highway to avoid a collision and simultaneously figure out how to cancel this feature, which places a limit on the speed that the vehicle can travel. Instead of claiming that this feature malfunctioned, I am claiming that it is an egregiously, poorly designed and dangerous feature. The button to activate it is located on the steering wheel; consequently, a driver can easily activate it without meaning to do so. This inadvertent activation happened to me twice, each time impeding, however briefly, my ability to safely navigate a busy road. This feature was not identified when I purchased the vehicle; however, earlier this year Hyundai belatedly sent a letter to its customers titled "Understanding Manual Speed Limit Assist (MSLA) Feature," pointing out how to activate and disengage the feature (and providing a link to a website for a tutorial with more information: [XXX] .

SEAT BELTS

(NHTSA Tracking Number 11726105) I am updating my existing complaint regarding my 2024 Hyundai Tucson (NHTSA Tracking Number 11726105) for an ongoing safety concern involving an intermittent warning chime while driving. This issue began shortly after I purchased the vehicle in Nov 2025 and has been reported to the dealership multiple times over several months. The warning chime occurs randomly while driving without any visible warning message or dashboard alert. This creates uncertainty because I do not know what the vehicle is trying to warn me about, which is distracting and creates a safety concern while driving. The dealership previously replaced both front seatbelt buckle assemblies after identifying intermittent high resistance as a possible cause. However, after that repair was completed, the warning chime occurred again while I was driving to the dealership for a follow-up visit. This confirmed that the issue was not fully resolved. I immediately returned the vehicle to the dealership, and they are now performing further diagnosis. I was advised that if the issue reoccurred, the next possible areas for diagnosis could involve the instrument cluster or the control module, both of which are safety-related systems connected to warning alerts and seatbelt functions. In addition, during this same visit, the dealership confirmed there is an actual oil leak requiring repair. This is significant because when I first raised this concern after an outside inspection in December 2025, I was told it was likely leftover residue from a prior oil change. The dealership has now confirmed it is a real leak and kept the vehicle for repair while providing a loaner vehicle. Because this vehicle was sold as Certified Pre-Owned and these safety and mechanical concerns continue shortly after purchase, I remain concerned about the reliability and safety of the vehicle.

POWER TRAIN

While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. The vehicle was later inspected by an authorized dealership, which confirmed severe internal engine damage, including cylinder damage and engine misfire requiring major repair or replacement. No clear root cause has been provided. There were no prior warning signs or symptoms before the incident. WARNING SIGNS PRIOR TO FAILURE: NONE OBSERVED. The vehicle is available for inspection upon request. DEALER CONFIRMATION: YES. MANUFACTURER INSPECTION: UNKNOWN.
