2024 Hyundai Tucson brakes problems

Filed Nov 2, 2026 · Brakes, Engine · VA

The vehicle suffers from a severe, unresolved manufacturing safety defect causing an intermittent loss of propulsion during highway operation. On multiple occasions under highway acceleration, the engine RPMs spike high but the vehicle completely fails to respond or accelerate, causing a dangerous power drop down to 65 MPH in active traffic lanes. To regain throttle response, the driver is forced to execute an emergency lane merge to the highway shoulder, turn the ignition completely off to clear the system, and restart the motor. The vehicle simultaneously exhibits an progressive powertrain defect path, including severe drivetrain binding where shifting into reverse gear triggers a violent physical thud and blocks the rear axle from backward movement until excessive throttle is applied. The vehicle also has a documented history of chronic Cylinder 1 engine misfires paired with an active loss of interior cabin heat at an engine idle, which indicates an internal combustion cylinder block or head gasket breach. The authorized franchise dealership has continuously failed to execute a physical component teardown to resolve the underlying structural root causes. Instead, service drive personnel cleared stored error codes on a stationary vehicle while falsifying vehicle road-test odometer metrics on the final invoice. This vehicle is actively utilized for commercial child transportation and nanny services, and the manufacturer has had formal notice of these recurring, un-remedied safety defects under active corporate case files well within full warranty windows. An independent federal safety review into these drivetrain tracking parameters is requested.

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!!

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)

There has been an urgent safety recall with no fix for 4 months. I need the issue to be resolved so that my vehicle is no longer a safety hazard, but both the dealership I purchased it from and the manufacturer have stated that it's not a big deal.

I am reporting a repeated brake system issue on my 2024 Hyundai Tucson involving premature rotor warping and brake failure at very low mileage. On April 30, 2025 (11,007 miles), I first noticed significant vibration and shaking when braking. On May 29, 2025, Colonial Hyundai diagnosed the issue and resurfaced the brakes under warranty (Hyundai case #40826529). The issue persisted immediately after repair, and on June 13, 2025, I was informed that both front and rear brakes and rotors needed replacement. On June 19, 2025, all brakes and rotors were replaced under warranty, resolving the issue temporarily. Less than 8 months later, on February 12, 2026 (under 10,000 additional miles), the same braking vibration returned. The original dealer attributed the issue to driving behavior. At Hyundai’s direction, I sought a second opinion on February 26, 2026 at Piazza Hyundai of West Chester. They confirmed that the brakes and rotors again required replacement and indicated this was unusual for such low mileage. On March 16, 2026, despite the dealer’s findings, Hyundai Corporate declined to cover the repair under warranty. This vehicle has now required three brake-related repairs within a short period and low mileage, including resurfacing and full rotor replacement, followed by another failure. This pattern suggests a potential defect in the braking system, materials, or related components, rather than normal wear. Component/System Failed: The failure involves the braking system, specifically repeated warping/failure of front and rear brake rotors and premature brake wear. The vehicle and components are available for inspection upon request. When braking, the vehicle experiences significant vibration and shaking in the steering wheel and chassis, which affects braking smoothness and control. This condition can reduce driver confidence, increase stopping distance, and may lead to loss of control during braking, particularly at highway speeds or in emergency stop.

Driving to work, going into a turn with no obstructions my car frequently alerts to a "collision warning" that is not there. Additionally, I have been driving on the highway, with no obstructions in front of me and my car emergency brake despite an emergency not being present. In both instances, it is extremely distracting and induces anxiety as I am alerted of a threat that is not there. Further at highway speeds (65-70 mph) on the highway, and braking despite having no emergency nearly caused an accident. I was able to push further down on the gas to force the car to keep going to not stop on the highway. The collision warning has been an issue since purchase of the car in June 2024, the emergency brake occurred in February 2026.

I was driving on the highway with no one in front of me. The car suddenly slammed on the brakes and flashed "emergency breaking system" on my dash. My car went from about 75 mpg down to 50. The car behind me almost rear-ended me. He then proceeded to pass me and brake check me because he thought I had deliberately brake checked him. This incident caused the man behind me to get road rage and react dangerously to me. I hit the gas and it finally stopped breaking and let me gain speed up again. It was terrifying. This is not the first time this has happened but it was the first time in the highway. It has happened several times on side roads for no reason either. I have an appointment with Hyundai to figure out what they can do because I don't feel safe driving this car.

At high speeds above 40 MPH vehicle automatically brakes with no vehicle or objects in front while vehicle is in operation. Very concerning when driving on interstate.
