2024 Hyundai Tucson Complaints

(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...

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 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)

Component: Engine/Powertrain/Electrical System Incident Description: I am reporting a recurring, life-threatening "Loss of Motive Power" (Dead Pedal) in a 2024 Hyundai Tucson (Alabama-built). On multiple occasions, the vehicle has failed to respond to throttle input during high-risk maneuvers, specifically while merging into 45+ MPH traffic. The vehicle "chugs" and stalls, refusing to exceed 15 MPH despite full accelerator depression. This defect leaves the vehicle and its occupants stranded and defenseless in the path of oncoming high-speed traffic. Technical Context: This vehicle is currently subject to NHTSA Recall 23V-526 (Hyundai Campaign 246) for electronic controller damage that can cause "CAN communication disruptions." I believe the "Dead Pedal" failure is a direct result of these communication disruptions between the engine and transmission control modules. Furthermore, Hyundai has issued TSB #24-AT-001H-1 for "Hesitation when accelerating," yet the authorized dealer (Ed Voy...
