Electrical System Problems of Land Rover Discovery - part 1

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 went out in December. The vehicle has 53,000 miles on it, so it is just out of warranty. I live 100 miles from the nearest dealership so I had it towed to a local shop. I was originally told the part was on back order until mid-February. I was told yesterday, they think it may not be available until may 2026. If this is such a big issue that they can not keep up with the part, why is this not a recall item?.

Water began leaking into car from front windshield while driving on 11/25/2025. Air whistling noises present also. Safety risk of injury from windshield failure. Repair person says risk for windshield coming off when driving or if involved in collision. Possibly related to recall n221 Land Rover Discovery se 2018. Had koch 33 perform assessment and they reproduced water and air leak and determined windshield is loose and not adhered. Erie insurance says not covered and it is "wear and tear. " no warning lamps or other symptoms prior to failure. Fearful of windshield coming loose/off if involved in crash and fearful that the water may be affecting the electrical system of internal lights and sunroof/moonroof. Available for inspection upon request.

This vehicle has an active water intrusion from the headliner above the windshield due to windshield bonding and body seal failure. Water is dripping down and entering the dashboard area and shorting electrical control modules behind the media/glove box and media console. Each time the media/glove box is opened, the hvac system shorts and forces the defrost system to activate involuntarily. The vehicle also exhibits park brake fault warnings, delayed and intermittent no-start conditions, brake fluid loss, and electrical instability. This is an active electrical short inside federally regulated safety systems, making the vehicle unsafe to operate. The defect is progressive and continues to worsen.

The windshield seal failed at the top of the windshield, allowing significant water intrusion into the vehicle cabin. The windshield had previously been replaced under a manufacturer recall/service action, but that repair failed. Water intrusion caused failure of the occupant restraint control module (rcm), impairing airbag system functionality. Water also damaged the audio amplifier and other electronic components. Interior flooring and insulation are saturated and require removal and remediation. The defect was confirmed by an authorized Land Rover dealer, who identified the source of the leak as a defective windshield seal. Warning messages related to vehicle systems appeared after the water intrusion was discovered. The vehicle is no longer safe to operate due to compromised safety systems. This is the second Land Rover Discovery I have owned that has experienced catastrophic windshield sealing failure resulting in extensive water damage. The manufacturer declined responsibility and advised filing an insurance claim.

Defect summary: repeated water intrusion (windshield, roof rails, rear door latch) leading to electrical damage. Electrical failures resulting in sudden loss of power, lighting, and infotainment. Critical safety system failures including: sudden loss of steering assist and brake assist while in motion. Vehicle stalling with the engine running but no drivetrain response. Gear shifter malfunctions leaving the vehicle stuck in gear. Notable incidents: July–August 2025 (61,000 mi): multiple events of complete power loss while driving, including loss of steering and braking control on a public roadway. September 11, 2025 (post-repair): after dealer-replaced battery and gear-shift module, the vehicle failed catastrophically within 450 feet of leaving the service center, jolting violently, losing all electrical power, and leaving steering and brakes stiff. An edison police officer witnessed the event and assisted in traffic control. Safety concern: these recurring failures present a clear and ongoing danger of crash, injury, or fatality. The pattern demonstrates a systemic design or manufacturing defect related to water ingress and electrical integrity.

There is a safety recall for the 2019-2020 Land Rover Discovery models. 414-01 safety recall: startup battery ground stud - insufficient ground contact Land Rover tech bulletin dated 09 Dec 2020 on July 25 my 2017 Land Rover Discovery lost power, instrumentation went haywire, and steering limp as I was making a turn onto us-90. On August 5 it would not start. Eventually jump started it, as the battery did not seem to register to the vehicle. On August 6 it again lost power, drive train went limp, all warnings lit up, and steering died as I was getting onto I-95 on August 7 jlr of jacksonville informed me they found arching burn marks on the battery ground stud. They knew this as a common issue from the previous tech bulletin. The 2017&2018 have the same design as the 2019&2020, why are the 2017&2018 not included in the recall?.

Vehicle electronics began going crazy. The instrument cluster and gages just started flashing and pulsating. The transmission and mode selection cluster lit up like a christmas tree. The engine power and steering went limp. The transmission eventually stuck in drive. This occurred twice while driving on the roadway. The second time I had it towed to the dealership. The dealership found the m6 ground stud to be arching. This same issue is a technical bulletin for the 2019-2020 models, but 2017-2018 which are of the same design and build were left off the recall.

The contact owns a 2019 Land Rover Discovery. The contact stated that while driving at 20 mph and entering the highway, the vehicle shut off. While driving at 45 mph, the vehicle shut off and restarted. The vehicle coasted after stalling. The vehicle was shifted into park and then into drive to continue driving. There were no warning lights illuminated. The contact linked the failure to NHTSA campaign number: 20v694000 (electrical system) and 19v040000 (engine). The contact received notification of NHTSA campaign number: 23v393000 (electrical system, latches, locks/linkages). The local dealer was contacted, and confirmed there was a cyberattack on the computers, and they would be down until October 2025. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 65,000.

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.

Driving down the highway at night in the rain and car died completely. . . All electronics shut off, car shut off and had no power to steering or breaks or anything. Would not start once it was pulled over and had to be towed to dealer. At the dealership I was told the leaking windshield had eroded the wiring throughout. They could not start or power the car at all. They removed the complete interior and have had the car for 45 days with no estimate of when it is drivable again.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Front parking aid sensors do not alert me to objects in front of me when parking forward. I have to first backup two feet to get it to work, then it picks it up once I put in forward motion again. The dealer stated that they have no recalls for this problem even though my vehicle is in warranty.

Complete loss of all electrical power (while driving, although incident occurred at a stop-light) due to ground stud failure. Component previously subject to a recall in 2021. Appears that the manufacturer fix implemented as part of the recall failed.

Driving down the highway, the vehicle all the sudden started smoking, forcing me to pull over. Upon pulling over, I found it was a fire under the left front hood based on the smoke pouring out. I called 911 immediately. I attempted to save some belongings, including my $200k boat, but failed to save anything as the fire rapidly grew forcing me to step far away. I then watched my car, boat and belongings all perish to nearly nothing before the fire department arrived and put out the fire. While I am lucky to be safe and have adequate insurance, others may not fair so well when their Land Rover Discovery 5 petrol catches fire.

I was in a parking lot adjusting settings via the touch screen when the vehicle suddenly deactivated the key fob rendering the vehicle useless. The only option was to get the spare key to start the vehicle. This presents a safety issue for all occupants if the vehicle is disabled because of a malfunction with the key, potentially leaving people stranded in a unsafe environment.

I was completely stopped at a red light. I have just left work and was 2 miles down the street. My rear window completely exploded. Glass flew everywhere. The noise was so loud that it caused ear pain. I have requested a complete inspection from the dealership along with a review of the edr system and sdr. This happened on Wednesday 3/15. I am concerned this was electrical given the car had only been turned on for 3 minutes and I was at a complete stop with zero impact. I am concerned for this to happen again with my children in the car or for the possibility of a short circuit affecting the airbags, additional window, breaks, anything else. I have submitted videos and photos to the dealership to review and as you can see the points are at the electrical boxes on the left and right side of the window. I would like this reviewed for safety concerns.

The contact owns a 2019 Land Rover Discovery. The contact stated while reversing and when the contact shifted the vehicle into park, the warning light illuminated stated that the vehicle was in driver. The contact turned shutting down the vehicle, but the vehicle would not shut down, the contact disconnected the battery, and the vehicle was able to operate normally. The vehicle was taken to the dealer and the dealer stated that they believe it was the shifting box needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and the manufacturer stated the vehicle warranty had run out. The failure mileage was 70,000.

Windshield replaced three times faulty seal, tires defected fell apart within two years less than 10,000 miles on vehicle.

Windshield leak cause water to drain into floor boards and accumulate until electrical connectors were affected. The dash and display screen went completely black when driving, as well as the car refusing to start.

Vehicle warning lights come on including traction control and engine warning. Vehicle stops running after halting and then quits running completely. I had the vehicle towed 80 miles to the nearest dealer in columbia, SC they reported that it was a loose ground wire on the battery and told me it was resolved. Less than a month later the same thing happened again and all 4 wheels locked up requiring the towing company to drag it onto the flat bed two truck. It was towed to the local dealer in hardeeville, SC for repair last Friday and am waiting on a notice that they are working on the vehicle. I did report the issue to the local dealer prior to the latest event and was told that the earliest available appointment was a month out. I was not told of any recall by either dealer but was told that they are having the same issue with “so many cars” the first event was on September 13th and the second on October 14th.

The car will go dead. Had battery replaced at dealer on 5-28-22. 2 days later the car was dead and will not start. After messing with the negative cable where it’s connected to the chassis was able to start the car. After the car was running for about a minute the negative cable was very hot to the touch. This has been an ongoing problem with this car. After see other recalls for this battery cable issue am afraid the car could die while driving it. Our VIN is not associated with any recall. We feel the car is unsafe to drive and can also leave was stranded.
