My vehicle has been in for service 4 times for the front brake rotors warping. The dealer/manufacturer is not able to fix nor diagnose the root cause of the issue. They have replaced the rotors twice and turned/resurfaced the rotors twice - all in 26000 miles. The dealer has all but given up on the issue - and has referred me to Hyundai Customer Care (Corporate) where I have logged a case. In…

The failure pattern owners describe
Buyer takeaway: 2023 Tucson brake complaints include unintended emergency braking at highway speeds, complete brake failure, recurrent rotor warping, and parking brake failure. Dealerships have been unable or unwilling to diagnose and repair these issues, with some customers reporting the manufacturer is also aware but has not provided a remedy.
Owners of 2023 Hyundai Tucsons report eight distinct brake system issues. The most common involves the forward collision avoidance or automatic emergency braking system activating without a legitimate threat—drivers report the system engaging at highway speeds with no vehicle in front, causing sudden hard stops and putting them at risk of rear-end collision. Several owners state the dealer could not diagnose the problem without illuminated warning lights.
Other owners describe complete brake failure—one vehicle would not stop at 20 mph despite brake pedal application; another continued accelerating with the pedal fully engaged, requiring a tree collision to stop. A separate incident involved the brake pedal sinking to the floor with loss of pressure, which the dealership initially claimed was normal after checking a demonstration vehicle.
Brake pulsation and rotor warping appear widespread. One owner had rotors replaced and resurfaced twice within 26,000 miles; the service manager acknowledged "half a dozen" other vehicles with the same issue. Owners report the problem recurs even after service.
A parking brake failure caused the vehicle to roll backward out of park onto a public street twice. Multiple owners report emergency braking deploying randomly on highways with no visible cause. One vehicle displayed a cluster of warning lights (ABS, check engine, low oil pressure, forward collision avoidance) at 6,200 miles but was not yet diagnosed.

Failure modes owners describe
Overly aggressive emergency braking (collision avoidance system)
Forward Collision Avoidance System (FCAS) or automatic emergency braking triggered without legitimate threat, causing sudden hard stops. Incidents report system activating when no vehicle was in the path or threat distance, causing passengers to be thrown forward and creating rear-end risk.
When: Various speeds (35–75 mph); reported within first months of ownership
Symptoms owners cite: Sudden hard braking without warning or justification; Vehicle jerked to a stop on clear highway with no traffic ahead; Sequence of beeps prior to braking; Passengers thrown forward; seatbelts engaged sharply; Risk of rear-end collision from following traffic
Codes mentioned: Forward Collision Avoidance active
Repairs/costs cited: Owner stated intention to have dealer deactivate system; one owner reported dealer unable to diagnose without warning lights illuminated
Brake pedal sinking (loss of pressure)
Brake pedal gradually sinks to the floor during braking without full stopping power. Dealership initially dismissed as normal; condition mirrors master cylinder seal failure but owner was told it was not a defect.
When: 1,700 miles after new purchase (January 2023)
Symptoms owners cite: Brake pedal sinks gradually and goes completely down after stopping at red light; Reduced or loss of braking force; No warning lights
Repairs/costs cited: No repairs made; dealership stated behavior was normal after comparison with newer demo vehicle
Brake pulsation and shaking on braking
Vibration and shaking felt through pedal and vehicle during braking, especially at higher speeds and on downhill grades. Rotor and pad replacement provided temporary relief but condition recurs. Owner reports this is a recurring issue across multiple 2023 Tucson owners.
When: Approximately 4 months after lease start; recurred after rotor/pad service
Symptoms owners cite: Vibration and shaking when braking; More pronounced at higher speeds and downhill; Reduced control during braking; No warning lights
Repairs/costs cited: Brake pads replaced temporarily; rotor replacement/resurfacing performed but issue recurs. Service center confirmed problem was physical and verifiable.
Brake failure (complete loss of stopping power)
Total loss of braking function; brake pedal unresponsive and vehicle continued to accelerate despite releasing accelerator and pumping brakes. Vehicle could not be stopped and required collision with tree to prevent pedestrian impact. Vehicle was totaled.
When: 22,600 miles; one incident at low speed (20 mph)
Symptoms owners cite: Brakes do not respond when pedal is depressed; Vehicle continues to accelerate even after releasing accelerator; Pedal pumping has no effect; No warning lights illuminated; Vehicle will not stop even in neutral
Repairs/costs cited: One incident involved steering onto grass and shifting to neutral to stop; another resulted in collision with tree. First incident at 20 mph—dealer refused diagnosis without warning lights.
Warped front brake rotors
Front brake rotors warp repeatedly despite multiple service attempts. Rotor replacement and resurfacing have not resolved the underlying cause. Dealer service manager acknowledged other vehicles with same issue; condition is documented as known problem in Hyundai owner forums.
When: Occurring within 26,000 miles of ownership
Symptoms owners cite: Brake vibration and pulsation; Reduced braking effectiveness
Repairs/costs cited: Rotors replaced twice and resurfaced twice within 26,000 miles. Dealer unable to diagnose root cause and referred customer to Hyundai Corporate Customer Care. Service manager stated awareness of 'half a dozen' similar vehicles.
Recalls/TSBs owners mention: Corporate case logged with Hyundai Customer Care; no resolution provided. Known issue in Hyundai owner forums; manufacturer response or remedy not documented.
Parking brake failure (vehicle roll-back)
Vehicle rolls backward out of park on slight incline despite engaging parking brake. Occurred twice in succession, creating risk of collision with street traffic and children.
When: Not specified; early in ownership period
Symptoms owners cite: Vehicle rolls backward when parked on slight incline; Occurs even after engaging parking brake
Randomly activated emergency braking on highway
Emergency braking system engaged without warning or threat while driving highway at steady speed. Activation caused sudden jarring stop with no apparent trigger, repeated on multiple occasions.
When: Multiple occasions; no mileage specified
Symptoms owners cite: Emergency brakes deployed randomly while traveling on highway; Vehicle came to abrupt jarring stop with no justification; Repeated occurrences; Created dangerous condition for following traffic
Repairs/costs cited: Dealer unable to assist due to intermittent nature of fault
Warning light cluster (ABS, check engine, low oil pressure, forward collision avoidance)
Multiple warning lights illuminated simultaneously, indicating possible broader system failure affecting brake and engine control.
When: 6,200 miles
Symptoms owners cite: ABS warning light illuminated; Check engine light illuminated; Low oil pressure warning light illuminated; Forward Collision Avoidance warning light illuminated
Repairs/costs cited: Vehicle taken to dealer but not yet diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer not notified

What owners are reporting 2 most recent
On multiple occasions, my new Hyundai Tucson randomly deployed emergency brakes while traveling on highway. This created a dangerous condition as my vehicle started braking without reason which prompted vehicle following my vehicle to slam on their brakes.
