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.

The failure pattern owners describe
Buyer takeaway: A 2024 Tucson in this cluster shows two serious patterns: repeated rotor warping at very low mileage (requiring multiple warranty replacements, then denial) and unintended emergency braking triggered by faulty forward-collision sensors, some resulting in rear-end crashes. Brake squealing and erratic lane-keep/cruise control also reported.
Owners report two main brake-system problems: premature rotor failure and unintended emergency braking.
One owner experienced rotor warping and brake vibration at 11,000 miles, had them resurfaced, then required full rotor and pad replacement at 19,000 miles. Within eight additional months, the same failure occurred again—all at unusually low mileage for such wear. Hyundai covered the first two repairs (case #40826529 through Colonial Hyundai) but denied the third, attributing it to driving behavior. A second dealership independently confirmed the pattern was abnormal.
Multiple owners report the forward-collision warning system and emergency braking engaging without cause—no cars ahead, clear roads, rural areas, or highways with light traffic. The vehicle drops speed 20–30 mph almost instantly, triggering dash alerts. One owner was rear-ended; another required medical attention after an intersection collision caused by unintended braking. Several owners report near-misses and note the issue occurs in cruise control and normal driving alike. Hyundai kept one vehicle a week for diagnostics and found nothing.
A separate complaint describes continuous brake squealing from near-purchase onward; the dealership refused service, blaming moisture. Another owner reports unintended lane-keeping assist and cruise control activation at low mileage, causing abrupt swerving.

Failure modes owners describe
Premature rotor warping and brake wear
Front and rear brake rotors warp and fail repeatedly at very low mileage (11,000 miles and recurrence within 10,000 additional miles). Owner reports significant vibration and shaking during braking; dealership resurfaced brakes, then replaced all front and rear brake rotors and pads under warranty. Failure recurred less than 8 months later. Second dealership confirmed the pattern was unusual for such low mileage. Hyundai Corporate ultimately denied warranty coverage on the third occurrence.
When: First reported at 11,007 miles (April 30, 2025); recurred at under 20,000 miles (February 12, 2026)
Symptoms owners cite: Significant vibration and shaking in steering wheel and chassis when braking; Reduced braking smoothness and control; Potential for increased stopping distance and loss of control at highway speeds
Repairs/costs cited: First occurrence: brake resurfacing (May 29, 2025); second occurrence: full replacement of front and rear brake rotors and pads (June 19, 2025); third occurrence: recommended replacement denied by Hyundai Corporate (March 16, 2026)
Recalls/TSBs owners mention: Warranty case #40826529 (Colonial Hyundai, May 29, 2025). First two repairs covered under warranty; third repair denied by Hyundai Corporate (March 16, 2026). Dealer attributed third occurrence to driving behavior despite independent confirmation of unusual pattern.
Unintended emergency braking activation
Forward collision detection system and emergency braking engage without cause. Vehicle automatically brakes hard with no vehicles, obstructions, or pedestrians present. Occurs at highway speeds (40+ mph, including 65-70 mph) and in light traffic or rural areas with clear road conditions. Has resulted in near-miss rear-end collisions and at least one confirmed rear-end crash causing injury to owner. Events occur both in cruise control mode and during normal driving. Hyundai diagnostics (one week of investigation) found no defect.
When: Reported as early as purchase (June 2024 for one owner); recurring incidents through February 2026; multiple owners report at very low mileage
Symptoms owners cite: Sudden hard braking with no traffic or objects ahead; Speed drops 20-30 mph almost instantaneously (75 mph to 50 mph, or 45 mph to 15 mph); Red 'emergency braking system' alert on dashboard; False 'collision warning' alerts; Vehicle attempts to apply brakes while owner's foot remains on accelerator; Near-miss rear-end collisions due to unexpected braking; One confirmed rear-end collision causing injury
Codes mentioned: Forward collision warning system malfunction, Emergency braking system malfunction
Repairs/costs cited: Hyundai kept vehicle for one week of diagnostics; no defect found and no repair attempted. Multiple owners report dealer inability to diagnose or resolve issue.
Recalls/TSBs owners mention: Hyundai diagnostics inconclusive (no defect found after extended investigation). Escalation to corporate mentioned by at least one owner; no resolution documented. Owner speculation suggests potential recall opportunity given multiple reports of same issue across various model years.
Brake squealing
Persistent squealing noise when applying brakes. Occurs continuously throughout the day, every day, particularly at stop signs and traffic lights. Dealership service manager blamed moisture and refused replacement, stating it is not a defect. Owner and independent mechanics consulted characterized the squealing as indicator of brake malfunction rather than normal wear.
When: Reported about one month after purchase (new vehicle)
Symptoms owners cite: High-pitched squealing noise during brake application; Continuous occurrence multiple times daily; Occurs when applying brakes at stop signs and traffic lights
Repairs/costs cited: Dealership refused to replace brakes despite owner request and complaint.
Recalls/TSBs owners mention: Allstar Hyundai (Baton Rouge) service manager attributed to moisture and declined service; no warranty action taken.
Unintended lane-keeping assist and cruise control activation
Hands-free lane-keeping assist and cruise control engage without driver input, causing vehicle to swerve abruptly to the right. Owner had hands on wheel and was able to correct, but owner expresses concern about risk on mountain roads.
When: Reported on highway; vehicle has less than 4,000 miles at time of incident
Symptoms owners cite: Lane-keeping assist activated without engagement; Cruise control activated without engagement; Abrupt rightward swerve of vehicle; Loss of expected driver control responsiveness

While driving in light traffic, speed at 45 mph, my Tucson alerted me with a beep, steering wheel vibrated and a red alert on the dash was present for about 3 seconds then the speed automatically slows down to 15 mph all on its own while my foot is still on the accelerator. This has occurred at a minimum 6 times. I purchased this vehicle brand new and driving it off the lot it had 22 miles on it.…
Two incidents while driving on the highway. 1. Emergency braking activated on its own. No cars around me. It was a rural area. The red emergency braking activated light showed up and my car braked but resumed driving. This is a new car with less than 4k miles on it. 2. The hands free assist and cruise control were activated. My care swerved to the right abruptly. My hands were on the wheel…
I brought my vehicle in to Allstar hyundai in Baton Rouge about a month after purchasing it. I told the service manager my brakes are squealing through out the day. He drove it nothing. He stated it is because of moisture. Not true. Squealing brakes means the brakes will go out. They refused to change them out. It has continued to happen multiple times each and everyday. I would love to have this…
Sudden hard breaking for no reason. It's happened 3 times when in cruise control. If a car had been close behind it would have caused a wreck. I've had the vehicle just over a month
