Open the full vehicle complaint log (all categories)The contact owns a 2022 Land Rover Discovery. The contact stated that while driving at an undisclosed speed, the vehicle jerked, and several unknown warning lights were illuminated. The vehicle was pulled over to the side of the road and turned off. The contact waited before restarting the vehicle; however, after driving for several miles the failure reoccurred. The contact stated that on a separate occasion, the vehicle jerked, and the vehicle failed to accelerate as intended while depressing the accelerator pedal before the vehicle stalled. The message "Emergency Braking Assistance Not Available" was displayed. The contact was able to coast to the side of the road. The contact called for assistance and another driver arrived the scene and followed behind the vehicle back to the residence. The vehicle was taken to the dealer, where it was diagnosed that the ground studs were not connected and had failed to function as intended. The vehicle remained at the dealer unrepaired. The contact stated that before the electrical failure, the message "Check Coolant" was displayed. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 21V457000 (ELECTRICAL SYSTEM); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 76,000.
Car displayed a warning noting of an “an electrical fault” but was still running fine otherwise. Drove straight to service center roughly 5 miles away. About a half a mile away from service center the car experienced a cascading number faults in quick succession. First it was safety systems, then air suspension, followed by transmission and finally steering, which point the car was able to roll and some steering though required significant effort. This occurred during traffic, where luckily i had just gotten off the highway. I was able to coast the car into the middle of a shopping center parking lot where it became immobile. A fortunate timing of intersection traffic lights being green likely helped avoid a collision or hitting a pedestrian as all vehicle systems shut down. Towed vehicle to factory service center. Dealer confirmed a a failed DC-to-DC Converter (48V to 12V in mild hybrid system) led to vehicle shutdown and damaged auxiliary 12V battery. Requires a new DC to DC converter but is on backorder for weeks with no ETA available. Car remains immobile until a new part is received.
The DC/DC converter had failed after the recent software upgrade by JLR right in the middle of the road. Barely made to their shop. It has been a month since. No updates on the status of the fixing my car. Had call many times, no response. The car is in the JLR diller in Hunt Valley, Maryland.
