The contact owns a 2020 Land Rover Discovery. The contact stated that after his wife had started the vehicle, the "Charging System Malfunction" warning message illuminated. The contact stated that the driver had previously experienced intermittent loss of motive power for short periods while driving. The dealer was contacted and advised that once the warning message illuminated, the vehicle could shut off after approximately 22-30 miles. The vehicle was driven to the residence and was then towed to the dealer. The dealer diagnosed that the alternator had shorted due to an oil leak from the upper and lower timing covers, which required replacement. The manufacturer was notified of the failure, but no assistance was provided. The vehicle was not repaired. The failure mileage was approximately 44,836.

NHTSA complaint #11748240 — an unverified report by a vehicle owner.
2021 Land Rover Discovery 48V mild hybrid (MHEV). Recurring 12V system failures: repeated depleted/dead 12V batteries and no-start events. The 12V battery has failed and been replaced three times during my ownership (two documented at a franchised Land Rover dealer and an independent shop), plus a prior replacement under the previous owner per the vehicle history report. Symptoms: the vehicle will not start without a jump, repeated low-battery and SOS/telematics warnings, blank infotainment display, and full battery depletion after the vehicle sits unused for as little as 3 days, even with a battery maintainer in use. Dealer cloud diagnosis confirmed two contributing faults. First, elevated parasitic/quiescent current draw from control modules not entering proper sleep state, measured at 1.6A versus a normal value near 0.01A. Second, inadequate 12V charging. The dealer replaced the 12V and telematics backup batteries and applied software updates to multiple modules (including TCU and BCM), yet the failures recurred. This VIN has an open safety recall on MHEVs (NHTSA 26V-248, manufacturer D126) describing a DCDC converter internal fault that causes loss of 12V system charging and a "Stop Safely, Electrical Fault Detected" warning, with potential loss of motive power, coasting to a stop, and loss of exterior lighting. The remedy is not yet available. Safety risk: loss of 12V charging and battery depletion can cause stalling, loss of motive power in traffic, no-start and stranding, and loss of lighting, all of which increase crash risk. On one occasion the vehicle barely started after sitting at an airport lot, nearly leaving my family stranded. The problem has been reproduced and confirmed by both a franchised dealer and an independent service center. The vehicle and the failed batteries are available for inspection on request. Warning messages first appeared before the current failure and have recurred across multiple battery replacements.
NHTSA complaint #11742136 — an unverified report by a vehicle owner.
The contact owns a 2019 Land Rover Discovery. The contact stated that the vehicle had been experiencing electrical failures. The contact stated that the vehicle had failed to start or unlock, requiring the owner to manually unlock the vehicle with the key. Tand and exterior lights independently flashed while the vehicle was parked in the middle of the night. The vehicle was taken to the dealer on several occasions, but the failure could not be duplicated. The vehicle was taken back to the dealer, where it was diagnosed that the AC condenser was leaking on the tow hitch cable, shorting out the electrical system. The dealer performed an unknown repair; however, the failure persisted. The manufacturer was notified of the failure, and a case was filed. The contact referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 69,000.

NHTSA complaint #11738751 — an unverified report by a vehicle owner.
I was driving home from work late at night in December 2025. A Signal came on that said pull to safety or something like that and then I lost power steering and brake control and my entire dash in my vehicle went pitch black. I was in the middle lane on route 290 and I was very lucky not to hit any other vehicles, but it was incredibly scary because I had no control of my vehicle and there were many cars and trucks on the road around me. I coasted off slowly to the side and I had to sit in 15° temperatures for an hour while I waited for AAA to come and tow my vehicle. They towed it to my home and were not able to get it off the ramp so they had to tow it to the dealership because the battery had died. The vehicle for a couple weeks before was slow to start, which I did not realize at the time was a sign that the battery was being drained. It was brought to the dealer and discovered that the DC DC converter and the BECM was the issue. My vehicle is open for inspection if you need it. The converter and BECM have been replaced after fighting with the dealer and with Landrover. Landrover is aware of the situation because they had to work with the dealer on their systems.Unfortunately, I am out almost $1000 because they made me pay for the replacement of the battery ( and the towing ) . Honestly I am having PTSD every time I drive past the area where I almost crashed. Landrover did not even want to accept responsibility, but the dealer did as we have purchased two vehicles from them that we also maintain meticulously.

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.

NHTSA complaint #11737455 — an unverified report by a vehicle owner.
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.

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.

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

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.
NHTSA complaint #11733653 — an unverified report by a vehicle owner.
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.
