2024 Hyundai Tucson Problems

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.

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

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.

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

The same incident has occurred 4 times ( [XXX] While driving on the freeway in light traffic and no vehicles in front. The forward collision sensor triggered dropping the vehicle in speed approx 30 mph almost instantaneously. This is San Diego so no snow, rain or sleet and we were driving eastbound each time with the sun at our back. Hyundai kept the car for a week for diagnostics and found nothing. We have since escalated to corporate and are going in for another round of diagnostics. We have been exceptionally fortunate that we were not rear-ended. We have since installed a dash-cam to record the next event INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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. The contact was concerned about the fire risk warning associated with the recall. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

Seatbelt is not fastening in the rear center seat

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.

I was in a car accident, and air bags didn't deploy.

My wife and I purchased a 2024 Hyundai Tucson in June.  Since February 28, 2025 the SRS indicator lights have come on twice. Hyundai replaced the airbag twice.  In March, the emergency brake system red lights illuminated, and the car came to an abrupt stop.  Luckily, there were  no Cars behind me.  Seconds later, the car resumed, and the lights disappeared. Hyundai dealership took the car in and returned it in two hours noting they could not duplicate. Several days ago, the same thing happened with the emergency brake system. Driving at approximately 40 mph the car slammed on brakes and the dash illuminated again.  No cars behind me. The dealership returned the car once again, noting they could not duplicate.   The car has less than 8000 miles.  I won’t allow my wife to drive more than 10 miles alone.  It’s unsafe. The manual states the car is not to be driven with any of the sys indicators on and to do so would cause serious injury or damage to the car.   I will send attachments of invoices, NHTSA complaints and Hyundai manual info about unsafe condition.

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.

My car was parked, without any trees or other objects that could possibly damage my car near by, and the glass on my front windshield cracked for absolutely no reason. It starts where the glass attached to the car and spreads to the middle of my windshield. I believe there is an installation defect because this car is only 2 years old and has never had any damage to it. I also read that this is a common problem with other Hyundai models.

While sitting in stopped traffic on the interstate in the dark in the rain on 11/25/2024 my car was in drive; my foot was on the brake. Twice the car rolled away despite my attempts to brake or put the car in Park (I shoved the shifter into Park and the car continued to roll). I rolled into the back of a semi because I could not get my vehicle to stop. This had already been noted as a problem with 2024 Tucsons, yet your search engine tells me there are 0 unrepaired recalls for my car. I want to call this out as an unrepaired recall. I have left it with the Hyundai dealer at the moment. They tell me if they cannot make the problem happen for them they won't do anything to fix my car. This is a dangerous situation for me and for anyone with a Tucson that may have the same problem.

Headlights get covered with slush and snow while driving causing you to lose vision of the roadway at night. You are not able to see creating a safety risk to you and others on the road, potentially causing an accident that would cause serious injuries or death. Yes, it can be inspected upon request. Notified our dealer and was advised that this has never been brought to their attention as a problem from any other buyer. During our last vehicle service at our dealership when notifying them of the concern no issues with the vehicle were found. Warning lamp (obstruction) appears while driving. When the warning lamp illuminates, we need to pull over (sometimes not in a safe environment), wipe the slush/snow off of the headlights and proceed traveling. After wiping the headlights off, warning lamp on dashboard returns to normal operations.

The contact owns a 2024 Hyundai Tucson. The contact stated while driving at an unknown speed, the icons on the dashboard and radio went dark; however, no warning light was illuminated. The vehicle was driven to a dealer; however, the dealer had not provided a diagnostic result. The dealer suggested that the icons on the dashboard appeared to be dark due to the dashboard cover. The contact informed the dealer that the icons on the dashboard appeared dark prior to the placement of the dashboard cover on the vehicle. The vehicle was not repaired. The manufacturer was notified of the issue and opened a case. The contact was also referred to the NHTSA Hotline to report the failure. The failure mileage was 7,260. The VIN was not available.

A service bulletin for windshields leaking into 2024 Santa Cruz and Tucson vehicles was issued on 11/02/23 from Hyundai, causing passenger side flooding.The length of time these models were exposed to or held water could pose these safety risks: 1 Corrosion of various mechanical and electrical parts from water entry for months that could cause safety risks at a later time. Ex. Certain Hyundai vehicles were recalled in 2006-2015 for fires originating from the ABS system due to liquid leaks and corrosion caused by failing seals and leaking water. The electric systems could short out, spark, and cause a fire, posing a risk even when the car was not in operation. 2 The possibility of the presence of invisible mold spores that grow quickly inside a closed car environment is a serious health risk for those who have a high allergy to mold, allergic asthma, COPD or other lung problems. 3 Some vehicles also experienced water entry from a firewall separation from the windshield. If the firewall is part of the unibody construction and protection for components and passengers, this is concerning. 4 Inadequate or improper repair instructions cause new owner concerns regarding the integrity of their vehicle. A. Hyundai only authorized dealers to “...insert sealant in the area that has been improperly sealed.” An auto water leak tech reported such windshield leaks require a glass company for repairs. The dealer reported around eight other vehicles have experienced the leakage at their shop. I know of no inspections by Hyundai or other service techs but is available. I did not know my car had water in the passenger side for the two months I had it. These models have been exposed to water entry from their manufacture date from this defect that somehow slipped through inspection and quality control. A Hyundai forum reported that some models experienced windshield leaks back in 2020. I am very concerned that this continues to be a cost cutting practice passed on to consumers.

Serious Safety Hazard: 2024 Hyundai Tucson Power Steering Failures I have had numerous power steering failures while this driving vehicle. During these incidents, the steering wheel is extremely difficult to turn. This is a serious safety hazard which could lead to a severe accident and loss of life. During each incident occurrence, I noted a red steering wheel with an exclamation point was displayed on the dashboard. The power steering function is restored once I have found a safe location to pull the car off the road and then I reset the car by switching it off completely and then starting it again. My local dealer has not been able to duplicate the problem nor determine the root cause. The dealership has escalated the issue to Hyundai America for technical assistance. I currently have an open case with Hyundai Motor America National Consumer Affairs. I have noted similar power steering failure incident reports posted on the NHTSA website for earlier model Hyundai Tuscon vehicles.

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
