2024 Honda CR-V Hybrid

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.

The contact owns a 2024 Honda CR-V. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the power-reduced error message was displayed. The contact stated that the vehicle was driving abnormally sluggish and failed to exceed 18 MPH. The vehicle was driven to the shoulder of the road and turned off. The contact waited for a while before restarting the vehicle. The vehicle was driven to the residence. The vehicle was taken to the dealer, where it was diagnosed with a hybrid battery failure. The contact was informed that the hybrid battery needed to be replaced. The vehicle was repaired. The contact stated that the failure had started shortly after the vehicle was purchased. The vehicle was taken to the dealer several times; however, the failure was not duplicated. The contact was relieved that the vehicle was repaired; however, the contact was fearful that the failure could recur. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was unknown.

October 10, 2024 at about 1200 hours, the entire dashboard display and the upper center console display unexpectedly went black with no visible readout after having drivin 1-1/2 hours on the highway. Pulling off the road, we were able to reset the brightness to maximum and just able to see the readout. This event continued to be repeated several times during the course of the day. We had less than 9000 miles on the odometer at the time. I have checked the fuses, battery, and battery connections-all are in order. This event again repeated itself two weeks later on our return trip. In addition, the fuel gage has failed to fully up date on the display after being reset at the pump. I'm concerned about the possibility of the computer being the problem. We have less than 12,000 miles on the CRV Hybrid. The danger to us and others is that we had no idea of our speed, fuel amount, safety warnings, turn signals, nor what other safeguards were not working. The car is available for inspection upon request. We felt that this safety issue was serious enough to report it nationally before taking it to the dealers, which we will now do along with the other safety recalls on it. At this time, it has not been inspected by manufacturer, police, insurance representatives. Upon completing our first aforementioned long trip, we have not seen the electrical problem repeat within the short distance we drive. Possibly related, the Lane Departure Warning has been activated for no apparent reaason.
