ELECTRICAL SYSTEM

3 complaints

While driving my 2021 Land Rover Discovery (MHEV) in active traffic, the vehicle suddenly displayed an “Electrical system fault – Stop safely” warning. Immediately after the warning, the vehicle lost power and shut down, leaving me stalled in traffic with no ability to safely move the vehicle out of the roadway. There was no prior warning, no gradual degradation, and no driver-caused condition. The shutdown appeared to be related to the 48-volt mild-hybrid electrical system, possibly involving the DC-DC converter or battery management system, which disabled critical vehicle functions. This failure created an immediate safety hazard. I was at risk of being rear-ended and had limited ability to safely exit traffic. The vehicle became effectively inoperable without warning, which is unacceptable in real-world driving conditions. What is especially concerning is that: •The warning instructed me to “stop safely,” yet the vehicle did not allow time or power to do so •There were no visible issues beforehand •The issue appears consistent with known Land Rover MHEV electrical failures •Software updates were present, but did not prevent the failure A sudden electrical shutdown in traffic poses a serious safety risk to drivers, passengers, and others on the road. This issue should be investigated for potential defect, recall, or mandatory repair, as it compromises safe vehicle operation.

I own a 2021 Land Rover Discovery with VIN [XXX] , and I am experiencing issues that align with the national recall for the MHEV battery. My vehicle’s start-stop functionality fails intermittently, and the system is in an “offline state,” disrupting communication and critical functions. Additionally, due to these MHEV battery errors, my vehicle cannot receive over-the-air updates provided by Land Rover, further impacting its performance and reliability. I request that my vehicle be reviewed for inclusion in the recall and that the necessary repairs be covered. This ongoing issue presents a significant inconvenience and safety concern.

This is an update to Complaint Number 11436854, submitted on 10/14/2021, 5:53:21 PM Additional service has been performed on the vehicle to identify and correct random electrical faults interrupting the safe operations of this vehicle. Service record generated by Land Rover Boise, ID (RO Number 520844) is attached as an uploaded file. This RO indicates the third repair by Land Rover dealers that have serviced this vehicle (Lynnwood, WA; Flatirons, CO and Boise, ID) regarding the Ground Stud Update, and now provides the documentation of another ground fault in the Locking Actuator (door locks are randomly actuating w/driving).

This vehicle should be considered as a "drive at your own risk" vehicle. Engine randomly fails to start using push button start in coordination with pressing on the brake pedal. Dash and gages indicated all electrical systems were on and no warning symbols were displayed. Repeated attempts by owner to start vehicle failed. Attempts using remote start app erroneously indicated that the vehicle was already in operation. Fail-to-start generally existed for 2-4 hours before the vehicle would randomly start. Failure to start and stranding owner repeated 4 times over the next 8 days, including while the vehicle was in service shop of Dealer. Dealer service could not identify source of the problem and produced records that the safety recall for the battery ground stud issue had already been performed. Dealer service records (attached) recommended against driving vehicle due to "what seems to be intermittent high speed power train communications fault". Owner has requested Dealer By Back due to this repetitive and unresolved safety problem. Refusal from Land Rover to buy the vehicle back places this consumer safety issue back into owners hands which triggered the moral obligation to submit this information to the NHTSA as a safety problem.
