2020 Land Rover Defender

The contact owns a 2020 Land Rover Defender. The contact stated that while starting the vehicle, the check engine warning light illuminated. The following day, the contact’s spouse started the vehicle, and the message “High Voltage Shutdown Not Possible – Live System” was displayed. The contact stated that after an inspection, DTC: P0A7B was retrieved. The contact received notification of NHTSA Campaign Number: 26V248000 (Electrical System); however, the part was not yet available. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The approximate failure mileage was 48,000.

My 2020 Land Rover Defender 48V Mild Hybrid Electric Vehicle (MHEV) experienced a check engine light and hybrid electrical failure. Diagnostics by an authorized Jaguar Land Rover dealer confirmed code P0A1F-96 (Battery Energy Control Module / BECM internal component failure). This failure relates directly to an active, global safety recall issued by JLR (NHTSA Campaign 26V248 / JLR Recall D126) regarding DC-DC converter failures in MHEV vehicles. According to JLR recall documentation, a microchip failure in the DC-DC converter causes a total loss of 12V system charging, leading to electrical warnings and a sudden loss of motive power/propulsion while driving. CHRONIC CHARGING SYSTEM FAILURE: This vehicle has suffered from unresolved, long-term 12V charging system degradation caused by this MHEV subsystem defect. This chronic lack of proper charging has directly destroyed three (3) primary 12V main batteries and the emergency telematics (SOS) backup battery over a 4-year period. Replacing these auxiliary batteries failed to fix the underlying issue because the MHEV system/DC-DC converter continuously fails to maintain adequate charging across vehicle systems. This continuous voltage collapse eventually triggered the permanent BECM hardware lockout code (P0A1F-96). SAFETY HAZARD: A sudden loss of 12V system charging and subsequent loss of propulsion on public roads or at highway speeds presents a severe crash hazard to occupants and other motorists. STATUS & DEALER REFUSAL: An authorized JLR dealer confirmed code P0A1F-96 and documented "Pending Recall Campaign D126ADM2" on the official service invoice. Despite this being an acknowledged, safety-related defect in the MHEV system leading to loss of drive power, JLR North America and the dealer refuse to repair or grant goodwill coverage under the active safety recall framework, quoting over $3,400 out-of-pocket. The vehicle is available for inspection.

I own a 2020 Land Rover Defender and have experienced a failure of the LED halo ring/daytime running light within the headlight assembly. The LED ring stopped functioning even though the headlight assembly has not been damaged, modified, or involved in any accident. This failure affects the vehicle's visibility and appearance and may create a safety concern because the daytime running light is no longer operating as intended. I contacted the dealership regarding the issue, but I was informed that the repair is not covered under warranty, despite similar LED halo and DRL failures being reported by other Defender owners. I am requesting that this issue be investigated, as it appears to be a defect in the headlight assembly rather than normal wear and tear.

The DC/DC converter is failing on the vehicles regularly. This results in the vehicle losing power and shutting down while driving. I own this vehicle and while it hasn’t happened yet, I constantly fear that it will. With the common knowledge and frequency of this occurrence, Land Rover should fix as a recall to ensure the safety of all customers. Please push for this. Thank you.

While using the heated steering wheel function on my 2020 Land Rover Defender, the steering wheel began to overheat significantly after being turned on for a short time. The surface temperature became so hot that it burned and discolored the leather, releasing a strong burnt smell. This overheating poses a serious fire hazard and could easily burn the driver’s hands during operation. This issue compromises driver safety because the steering wheel is an essential control part of the vehicle. If the driver’s hand is burned or the leather catches fire, it could result in loss of control of the vehicle. There were no warning messages or lights before or during the incident. The problem has occurred multiple times and can be reproduced when the heated steering wheel function is activated. The vehicle is available for inspection upon request. I believe this is a critical safety defect that should not occur under normal operation and could potentially affect other vehicles of the same model.

My car does not fall under the VINs specified in recall N599 but is exhibiting the same unsafe conditions. At a rolling stop in traffic the car asks me to manually select a gear (while in Drive) and then shuts off the engine. The engine then will not restart and I am in unsafe conditions in intersections. I have brought the car to the dealership several times to resolve this and it continues to worsen. It has become a daily event and is now back at the delaership where they have told me it is not affected by this recall but clearly exhibits the same issue as described in that recall. This is a MAJOR SAFETY issue! The car shuts off without warning and wont restart. This is engine electrical system and transmission related. It drains the battery and leaves the car inoperable

Engine light came on while at a stop light, engine faltered completely and car stalled. Would not restart. Shifted car into Park and tried multiple times to restart, finally got it restarted. Rolled forward per the flow of traffic and engine died again in the middle of the intersection putting me directly in harm’s way. Multiple lights including engine light and dash warnings appeared. Pictures attached. This is a major safety issue, the car died and I could not move it forward. I was almost hit and could not get the car restarted, not once but twice. I have owned the car for less than one week, and it’s been back in the shop now twice. The first time ( Wednesday) was also for electrical issues, including sensor issues.
