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.

Vehicle Information: 2024 Hyundai TucsonComponent: Service Brakes, Hydraulic: Foundation Components: Disc: RotorComplaint Text:I am writing to report a severe, premature manufacturing defect regarding the braking system on my 2024 Hyundai Tucson. At approximately [Insert Your Mileage, e.g., 12,000] miles, the vehicle began experiencing violent shaking and vibration in the steering wheel and brake pedal when applying the brakes.Upon inspection, it was determined that all four factory brake rotors had warped. Shaking of this magnitude during braking compromises vehicle control and poses a distinct safety hazard, especially during high-speed or emergency braking maneuvers.Hyundai is fully aware of this defect. They previously issued Technical Service Bulletin TSB 23-BR-004H detailing an identical "brake judder" engineering flaw for 2022–2023 models. Despite the 2024 model utilizing the exact same braking architecture, Hyundai has not extended the TSB coverage to the 2024 model year. As a result, the dealership classified this premature failure as normal "wear and tear" and forced me to pay out of pocket for resurfacing all four rotors.A vehicle should not suffer total, four-wheel rotor warping at this low mileage. This is a systemic material defect that Hyundai is actively forcing consumers to pay for. I am requesting a formal safety investigation.

All four rotors warped with 7,209 miles it still had 8mm of metal and the dealership is saying it for hard braking which just about impossible!!

I purchased this vehicle brand new in December of 2023 - It has an oil consumption issue which started on May 13, 2024 - I have had the vehicle to the dealership for repairs to resolve the issue 13 times so far - Vehicle is currently at the dealership and has been for 7 days and they have not done anything to rectify the issue - Dealership says they are waiting on Hyundai to give them the approval to proceed - They have not provided me with a loaner vehicle - I have had to rent a car so I can get to work - The vehicle only has 28,388 miles on it - The issue started in May of 2024 with only 5,412 miles on it - I filed a complaint with Hyundai Case # 40508090 but they have failed to repair the vehicle or buy the vehicle back from me - I need help with this issue and I don't know what else to do

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 unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the remedy to be available. The vehicle was taken to the dealer, and the trailer wiring harness was removed, and a dust cap was installed over the wiring receptacle. The dealer had not replaced the tow hitch electrical harness. The contact stated that because the tow hitch electrical harness was not replaced, the vehicle was no longer able to be used for towing. The manufacturer was made aware of the issue, and a case had been opened. The manufacturer confirmed that the tow hitch electrical harness would be replaced but could not provide a time frame for when the part would be available. The failure mileage was approximately 68,000.

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

On 6 occasions over the last 2 months when coming to a stop the engine will increase rpm to 1600 forcing much extra brake pressure to stop, forcing me to shutoff the engine. No codes or indicators and the dealer can't duplicate. I mentioned to the dealer that the car will accelerate while holding down the brake thinking that as a clue as to what's wrong and the service tech told me that is normal but as far as I know it isn't normal. I don't know what to do.

Rear, middle seat belt will not latch. Upon the first need, June 2026, of having to have five people in the 2024 Tucson we discovered that the rear, middle seat belt would not latch. This created an unsafe situation of driving in downtown Houston with an occupant being unable to be safely restrained in the rear, middle seat. Dealer has confirmed a defective rear, middle seat belt, but will not repair under warranty. Dealer claims the seat belt was damaged by the folding down rear seat.

Seatbelt is not fastening in the rear center seat

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 6 occasions over the last 2 months when coming to a stop the engine will increase rpm to 1600 forcing much extra brake pressure to stop, forcing me to shutoff the engine. No codes or indicators and the dealer can't duplicate. I mentioned to the dealer that the car will accelerate while holding down the brake thinking that as a clue as to what's wrong and the service tech told me that is normal but as far as I know it isn't normal. I don't know what to do.

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.

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.

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.

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

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.

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.
