Electrical System Problems of Land Rover Discovery - part 1

The contact owns a 2019 Land Rover Discovery. The contact stated that when attempting to back out of a parking space, the shifter was moved to reverse; however, the shifter failed to release from reverse. The vehicle was shut off, then restarted to reset the transmission, and at which time the shifter was able to be moved. The next day, while driving at highway speeds of approximately 55 mph, entering on an on-ramp, the vehicle began to lose power and suddenly decelerate, then the vehicle shifted to neutral. The contact coasted to the side of the road. The vehicle was towed to a certified mechanic, who diagnosed that the engine needed to be replaced and there were failures with the gearbox and other computer systems. The vehicle was repaired. The next morning, the shifter failure and start failure occurred again. The next day, the instrument panel began to illuminate the messages, "proceed with caution" and "gearbox fault detected. " the liquid crystal display (lcd) would black out, restart, and black out again. The failure would occur while idle, at which time they would have to place the vehicle in park, shut off, then restart it. The vehicle returned to their home and parked. The contact completed some research and found their experienced failure related to NHTSA campaign number: 26v248000 (electrical system); however, their VIN was not included. The manufacturer was informed of the issue. The manufacturer referred the contact to the NHTSA hotline to file a complaint. The failure mileage was approximately 116,000.

The gearbox failure warning light was illuminated. The vehicle decelerated, and the steering wheel seized. The contact stated there was an abnormal ticking sound coming from the vehicle. The failure had occurred while driving on a busy highway. The vehicle was driven to the shoulder of the road, where the engine seized. The vehicle was taken to a local goodyear where it was diagnosed with battery failure. The contact was informed that the battery needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to goodyear where it was diagnosed with a failed negative ground terminal sensor. The contact was informed that the negative ground terminal sensor needed to be replaced and reprogrammed. The vehicle was repaired. The contact was made aware of NHTSA campaign number: 20v694000 (electrical system); however, the VIN was not associated with the recall. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA hotline to report the failure. The failure mileage was approximately 65,489.

The car would not respond, yet the battery was charged. Our local auto shop identified the issue as an electrical malfunction in which the entire driver's side was affected, meaning the lights nor car would turn on or activate in any way.

This is a report of a failed remedy for safety recall n321 (recall #19v293). Records confirm that this vehicle had the recall repair performed on 12/09/2020. That repair has now failed. A certified technician at the dealership has confirmed via video that the windshield bond has detached, leading to significant water intrusion. This flooding has ruined safety-related electronic modules (cameras/audio) and caused significant mold growth in the interior, which is a biohazard health hazard. The manufacturer is admitting the failure but is refusing to provide a 100% covered remedy for this failed safety recall, offering only a 40% 'goodwill' contribution. The vehicle is currently dismantled and unsafe to drive. A failed windshield bond compromises the structural integrity of the vehicle in a rollover and prevents the proper deployment of the passenger airbag. Furthermore, the active electrical failures in the safety-related camera systems and the respiratory risk from mold growth make the vehicle unsafe for occupancy technician diagnosis summary technician name: skyler (Jaguar/Land Rover certified) date of diagnosis: March 23, 2026. Dealership: Land Rover parsippany, NJ key findings from skyler's video: direct admission of failure: "so what we have going on is the windshield is leaking. The windshield is leaking so we’re going to have to get the windshield resealed for you. " extent of water damage: "inspect the carpets and they are very wet all the way around on the vehicle. . . The vehicle does have like a mildewy smell. " safety/electrical failure: "initially when I pulled the vehicle in, the surround sound cameras were not working. . . It's possible that one of the modules had water in I opened a case with Land Rover corporate (case #[xxx]), which they have since closed after refusing to provide a 100% covered remedy for this safety failure. They offered only a partial 40% 'goodwill' contribution and refused further assistance despite the confirmed safety hazard. Information redacted pursuant to the freedom of inform.

Water coming from top part of the front windshield. This was previously fixed but after few years problem persists and started causing electrical issues. I already had to replaced computer out of my pocket even it was under warranty cause did not wanted to fix it.

Our DC converter caused an electrical malfunction which is apparently such a big problem that our dealership can not get the necessary parts to fix the problem. We are being told we are number 21 in line.

Dc DC converter failed while driving. Car shut down and rolled to a stop. Could jump start the car but would only work for 10 seconds or so to move it out of traffic. 1-2 month part delay.

3rd time the vehicle has experienced a electrical fault and renders the car undrivable and will shut down while driving regardless of where you are. Each time the vehicle has stopped while driving on an interstate.

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.

I purchased my 2024 Land Rover Discovery new in March of 2024. In October of 2025, I found a large amount of water leaking through my windshield. Land rover had my vehicle from October 2025 until April 2026. When it was returned to me it had mold in that had to be remidate3d and now my screen is starting to short. I am concerned of the safety of this vehicle and the amount of water that went into the electrical system.

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.

Mhev vehicle is offline; car completely shut down, resulting in loss of power on the road.

Supplement / update to prior NHTSA complaints regarding my 2021 Land Rover Discovery mhev (VIN: [xxx] y prior complaints, Jaguar Land Rover has issued recall 26v248 for DC/DC converter failure leading to loss of propulsion in 2021–2024 Land Rover Discovery mhev vehicles. My vehicle experienced the same real-world failure condition: sudden loss of propulsion in traffic with my children in the vehicle. Jaguar Land Rover corporate has stated my VIN is not included in the recall population despite my vehicle being a 2021 Discovery mhev and experiencing the same defect condition. I am submitting additional documentary evidence from Jaguar Land Rover portland showing that during the repair process: * I was advised the vehicle would only run while connected to external jumper power and would shut off once that external power was removed. * two days later, I was advised the installed battery would only charge to 6 volts and that another battery was needed to continue testing. These communications raise concern that this failure event involved broader electrical consequences and further support that my vehicle experienced the same defect condition described in recall 26v248. The dealership ultimately completed repairs and charged me for the failure, while jlr maintains my VIN is excluded. I am requesting NHTSA review whether my VIN was improperly excluded from the recall population and whether the affected vehicle population should be expanded.

I am filing a safety complaint regarding a sudden and complete loss of power event while driving my 2021 Land Rover Discovery. The vehicle experienced a DC-DC converter failure with no warning, resulting in a sudden shutdown. The engine lost power, critical systems went offline, and I was unable to shift the vehicle into neutral. The vehicle became immobilized in active traffic, creating a dangerous situation. This incident occurred without warning and left me with no ability to safely move the vehicle out of traffic or rely on normal emergency functions. This presents a serious safety hazard to both the driver and others on the road. The vehicle has been at the dealership since mid-January 2026. The dealer has stated that the DC-DC failure caused additional component failures. However, no root cause has been identified beyond “internal failure,” and I have not been provided confirmation that the system has been properly tested or that the issue will not recur. I am concerned that this failure can cause cascading electrical issues, including loss of the 12v system, impacting multiple critical vehicle functions at once. The lack of a clear diagnosis and verified repair raises concerns about reliability and safety. Given the sudden loss of power, inability to move the vehicle, and absence of a confirmed root cause or validated repair, I am formally requesting that the national highway traffic safety administration open a defect investigation into the mhev/DC-DC system. This failure creates a significant safety risk, including vehicles becoming immobilized in active traffic without warning. The risk of recurrence without a defined cause is especially concerning and may indicate a broader issue.

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.

The contact left the vehicle on the side of the road. The vehicle had not been diagnosed or repaired by a dealer or independent mechanic. The manufacturer was not informed of the failure. The failure mileage was 106,331.

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.
