NHTSA Complaint #11688691 — 2024 HYUNDAI PALISADE

Since early ownership, my Palisade’s ABS activates improperly on bumpy/uneven surfaces like railroad tracks, construction zones, causing brake pedal pulsing, vibrations, and significantly longer stopping distances. Braking feels ineffective, as if the brakes “don’t catch,” unlike my wife’s new SUV, which brakes normally on similar surfaces. This occurs at low to moderate speeds (10-40 mph) on dry, rough roads like potholes or gravel, but not on smooth pavement. I believe the ABS/traction control system misreads wheel speed, reducing braking efficiency and posing a safety risk. The issue occurs 2-3 times weekly crossing railroad tracks near my home and daily on my highway commute through construction zones. I must maintain extra following distance (4-5 car lengths at 40 mph) to compensate, which is challenging in traffic. This defect nearly caused two collisions. In both, braking on rough surfaces at ~30-40 mph (with 2-3 car lengths ahead) extended stopping distances, forcing me to swerve into the breakdown lane to avoid rear-ending vehicles. This endangers my family and contradicts Hyundai’s safety ratings, a key reason for my purchase. I reported this to Branfon Hyundai in East Haven, Connecticut at my 7,000-mile oil change around November 2024 and was verbally told it was fineand again at 14,000 miles and asked them to document it April 2025. Both times, they documented my complaint but claimed it was “normal ABS behavior” and felt typical, offering no repairs or diagnostics. After another recent incident today I research the issue and the [XXX] v. Hyundai lawsuit (filed May 2025, CA) confirm similar ABS issues in 2023-2025 Palisades. Please investigate this ABS defect for a recall to fix braking performance. My family relies on this vehicle’s safety and was the main reason I bought it and most people who have families are sold at this safety award. I can provide service records or videos if needed.
