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.

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.

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.

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.
