2024 HYUNDAI TUCSON Complaints

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.

On February 25, 2026 the car was brought to the service department where it was determined that a front tire had a separated belt which caused vibrations and failure to accelerate . On June 16, 2026 the car was brought to the service department for the same thing. Again a tire had a separated belt again 235/55R19101H

Automatic emergency braking stopped the vehicle because another vehicle in front turned right.

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

The contact owns a 2024 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 25V893000 (Trailer Hitches); however, the part to do the recall repair was not yet available. The contact stated that the dealer had exceeded a reasonable amount of time for the recall repair. The contact stated that a recall repair appointment was scheduled with the dealer and the vehicle was taken to the dealer for the recall repair; however, the dealer informed the contact that parts were not yet ordered.

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.

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.

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] .
