NHTSA Complaint #11715284 — 2024 HONDA CR-V

While driving under normal conditions on a dry road (no snow or ice), the vehicle experienced a sudden loss of braking performance while in motion. The vehicle was traveling approximately 10–15 mph and approaching an intersection with a red traffic light. A warning message appeared stating: “Brake system problem. Brake performance may be reduced. See your dealer.” Immediately after this message, braking performance was significantly reduced. Multiple attempts to slow the vehicle using the brake pedal resulted in minimal deceleration. The stopping distance was much longer than expected for the speed and conditions. The vehicle only came to a stop after the brake pedal was pressed with full force. Shortly after the initial brake warning, multiple additional safety-related systems went offline, including collision avoidance and other braking-related driver assistance systems. Approximately five to six warning messages appeared, indicating a cascading failure of safety systems while the vehicle was still in motion. The driver was able to slowly maneuver the vehicle to the side of the road and park safely. No collision occurred. However, shortly before this incident, the vehicle had been driven on a highway. If the same failure had occurred at higher speeds or in traffic, it could have resulted in a serious crash or injury. The vehicle is relatively new (approximately two years old, low mileage) and has been routinely maintained. There were no prior warning signs before this event. The vehicle is currently available for inspection at a dealership. A preliminary dealer explanation suggested a possible low or discharged battery; however, the cause of the braking failure has not been clearly established. This incident involved loss of braking performance while the vehicle was in motion, presenting a significant safety risk.
