2022 Land Rover Defender electrical complaints
Page 2 of 2: complaints 11 to 29 of 29, newest first, as owners wrote them.
The DC converter on our 2022 Land Rover Defender 110 failed. We received some electrical fault notices that would come and go inconsistently a few days before the incident. Land Rover told us to drive the car to the dealer to get repaired, even when we asked whether that was safe. On the way to the dealer, the car completely turned off in the middle of traffic and became a brick and had to be towed in negative degree weather to the dealer where it has sat for a month today. The car shutdown/lost control on Rt 1 in Massachusetts and was fortunately able to steer off the road into a parking lot before it became a brick in the middle of a parking lot, not in a spot or anything. The dealer expects this is a DC converter problem but the car is a complete brick and cannot turn on or be moved around at the dealer until the part arrives. We've been told the part is on back order for months and there is no timeline for when it will be repaired.
DC to DC Converter failed, rendering vehicle dead. No parts available to repair. Forced to wait for months.
DC to DC converter failure that displays a RED warning indicator that says "Stop Safely Electrical Fault Detected" with a red battery indicator symbol displayed simultaneously. I called the dealer as this is the 3rd time I have experienced similar electrical issues that have left me stranded since my purchase of this truck new Jan '22. The dealer brushed me off the first time telling me I didn't drive the vehicle enough, 2nd time they replaced the battery, now they said they had a bulletin (1 month prior) from Land Rover of known DC-DC converter failure with no ETA for parts. I was told by the dealer the steering could lock up and/or the vehicle could have brake failure. I had it towed 1 hour to the dealer. There are 10 other vehicle sitting at this one dealer awaiting the same part replacement and they never notified me of this issue when they were aware of the safety concerns a month prior to my 3rd incident. This is a now known nationwide issue with Defenders and I have a claim in for it to be covered under the factory warranty since my factory warranty had just expired 9 days prior especially given my prior record of electrical issues with this particular vehicle. This is still not resolved and it has been at the dealer for 18 days as it is not safe to drive and still awaits a part with no estimated time for repair.
Electrical fault detected - pull over safely error message appeared while driving, and when vehicle was shut off, low battery warning appeared. Started vehicle and attempted to put in drive and failed with drivetrain error, then suspension error and power steering error. Replaced 12V battery next morning and still received electrical fault error. Towed to dealer and diagnosed with DC-DC converter failure.

Factory warranty remaining 31 months or 31,905 miles. 1/8/2024 26,536 miles, L Headlight failure, electric door lock malfunction, air suspension failure. Headlight = warranty replacement. Service Department = no solution, diagnostic code or replication of electric lock or suspension issue. 3/26/2024 30,285 miles, R Headlight failure, Low Battery notification. Tested Battery- passed. Headlight- warranty replacement. 4/30/2024 32,175 miles, Low Battery notification. Tested Battery- failed. Battery replacement and battery reset module = warranty replacement. 11/7/20205 58,812 miles, Turbo Coolant O rings failed- mechanical. Service writer advised this is common for these engines in the V6 defender models. Repair estimate $642.77. Dealership - provided good faith discount. Customer agreed to and paid a negotiated repair totaling $377.30. Despite all repairs, electrical warnings continued off and on with Low Battery notifications, that would appear and disappear. 1/31/2026 (62,105 mi), electrical issue, Low Battery notification, then “STOP SAFELY – ELECTRICAL FAULT DETECTED” notification. Caused vehicle failuer & shut down. Required towing. "STOP SAFELY – ELECTRICAL FAULT DETECTED" notification – electronic fault affects: Power delivery, Steering, Braking, Stability systems. Dealership Diagnosed fault code P0D33-11, failed DC/DC converter and batteries. Replacement Cost +$2,467.38. DC/DC Convertor OEM Parts are on national backorder. 1-2 months lead time. QTY 15 units waiting. Low battery warnings & P0D33-11 code are related. Weak 12V battery = stress the DC/DC converter, fault codes, conversely, a failing DC/DC prevent the 12V battery charging. These repeated low-battery warnings and electrical failures are directly related to DC/DC converter failure and represent an ongoing electrical defect that originated during the warranty period, not normal wear and tear.
On January 25, 2026, while driving my 2022 Land Rover Defender 110 in Colorado on Interstate 70, the vehicle suddenly and completely lost power with no warning. There were no dashboard alerts, warning lights, or messages prior to the failure. The vehicle abruptly became disabled while traveling at highway speed, creating an immediate and serious risk of a crash, severe injury, or death to myself and other motorists. I was extremely fortunate to be able to safely maneuver the vehicle out of traffic and exit the highway. Given traffic conditions on I-70, this failure could easily have resulted in a major accident. The vehicle was undrivable and had to be towed to Flatirons Land Rover in Colorado on January 25, 2026. On January 26, 2026, after I had to repeatedly follow up with the dealership, I was informed that the failure was caused by a defective component related to the battery/electrical system. Although the repair is covered under warranty, the required part is on backorder, and I was advised the vehicle will be out of service for approximately six weeks. The dealership stated they cannot provide a loaner vehicle, leaving me without transportation. They said the dcdc converter and I don not understand and they did not explain well A sudden loss of power without warning at highway speeds represents a serious safety defect that puts drivers and the public at risk. I am concerned this defect may affect other vehicles and could lead to serious injuries or fatalities if not addressed.
The battery recharging system failed causing the entire vehicle to shut down. The suspension, gearbox, and starter all stopped working without warning.
Lost all power due to failure of DC/DC Converter, Part # 433123464 (or LR131043). This problem is widespread and the replacement parts are on backorder. Land Rover cannot provide an ETA for delivery of parts to dealerships as of 1/30/2026. This failure occurred immediately and the vehicle came to a complete stop while driving.
Safety Complaint – DC-to-DC Converter Failure Causing Vehicle Shutdown I am submitting this complaint to report a DC-to-DC converter failure that rendered my vehicle inoperable. The authorized Land Rover service department diagnosed a failed DC-to-DC converter. This component is part of the vehicle’s electrical system and its failure caused a loss of vehicle functionality. I was informed the replacement part is on national back order, with an estimated repair time of up to two months. Based on owner reports and service discussions, this appears to be a common failure affecting Land Rover mild-hybrid vehicles. Many reports describe sudden loss of electrical power, warning messages, and vehicle shutdown. This issue presents a potential safety risk, as failure of the DC-to-DC converter can result in loss of vehicle systems and may occur without warning, including while the vehicle is in motion. The vehicle is currently unusable. It is concerning that a critical electrical component with safety implications is failing at relatively low mileage and that replacement parts are not readily available. I am requesting the federal safety agency review this issue for potential investigation, recall, or other corrective action.
Vehicle display provided warning of Electrical Fault and shorty thereafter the vehicle "bricked" ie. became entirely inoperable. I was able to jump start the engine but as soon as the vehicle was disconnected from the jumping power source the vehicle's engine shut down. The vehicle was towed to the dealership. The tech with the towing truck jump started the vehicle and noted the problem appeared to be with the alternator (ie. excessive draw on the power source). The dealership has tentatively diagnosed the problem as the DC-DC converter which serves as the alternator in this vehicle. The part has been back ordered for quite some time. The failure of this component seems to be a widespread issue with a number of Land Rover models.
On [XXX], while driving approximately 30 mph, my vehicle displayed the warning “STOP SAFELY – ELECTRICAL FAULT DETECTED.” I immediately pulled over and restarted the vehicle, but the warning reappeared. Due to safety concerns and proximity to my home, I cautiously continued driving. Two blocks from my residence, I stopped briefly and received a message stating “BATTERY LOW – PLEASE START ENGINE.” After restarting and turning the vehicle off again, the original warning cleared; however, the vehicle has been completely inoperable since [XXX]. The SUV was towed for battery replacement and then towed again after diagnosis confirmed a failed DC-DC converter. The dealership has advised the earliest availability of the replacement part is February 19, 2026, resulting in over two months of total vehicle downtime. I have received minimal updates during this time. I reported this issue to Land Rover/JLR but have not received follow-up or resolution. Based on my research, DC-DC converter failure is a known safety issue, and JLR has prior awareness of this defect. This failure presents a serious safety concern due to loss of electrical function while driving, possibly emergency brake issue, along with unreasonable repair delays related to a known issue. I am requesting acknowledgement of this safety concern, clear communication regarding my case, and appropriate assistance due to the extended downtime and still having to pay a monthly car payment/insurance and manufacture warranty just expiring at the 50,000 miles. Thank you for your time, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
DC/DC Converter went out and car had to be towed away. Part is on back order for several weeks.
System electrical failure due to a faulty part (DC/DC Converter). This essentially prevents the charging system so the battery dies and the car becomes undriveable. When this occurred to us, the car was in the middle of the road and could not start or move impeding traffic. This is a growing problem among owners of this vehicle and so much so that the part is currently backordered due to so much demand. A warning message was displayed stating "Drive Safely: Electrical Fault Detected".
The car had electrical Warning- literally the vehicle in totality shut down and I needed a tow to dealership- after diagnosis an electrical part-DC CONVERTER PART # 433123464. The part is unavailable anywhere. I called tri-state area in my own attempts for my car to be repaired. I was advised my the dealer that EVERY DEALERSHIP IS WAITING ON 5-10 of the same part!! I was currently advised the part is being manufactured in the UK -shipping estimate date mid January 2026. If this is infact the situation -I would like someone to look into a recall- the $700 part expires with my warranty!!! In February 2026. The vehicle in dead-without the DC converter
My 2022 Land Rover Defender was equipped with a factory-spec winch (a WARN Xeon Platinum 10-S, with Land Rover-supplied surrounds, etc.) installed immediately upon delivery by a JLR dealership. The winch is setup for a wireless winch remote, which intermittently loses pairing to the actual winch control unit. Due to the design of the Land Rover mounts, however, the winch’s controls (necessary to reset and reconnect the remote) are entirely inaccessible. The truck has to be taken to a JLR dealer every time the winch remote disconnects, the bumper and winch surrounds must be removed, and the controls thereby accessed to reset the system. So, several days’ worth of work every time the remote happens to disconnect, which is not a workable design. I have had the unit examined and serviced four times by dealerships and none are able to address the issue as the issue is with the factory design itself. There are third-party solutions (from WARN) available to reroute the winch controls to an accessible location, which the dealership has recommended I undertake just to get the factory design to function sustainably. This will likely run me $3,000 out of pocket, just to address design issues with the original $6,000 factory accessory. I have already contacted JLR customer service, who offered me a $300 voucher for future dealership service. After many discussions about the insufficiency of this voucher, they suggested that I file a the federal safety agency complaint.
There were two separate issues. First was the battery dying once 4 months after purchase and again about 12 months after purchase. Both times we were lucky we were not out and about 4 wheeling like we normally do. Second is very recent about 18 months after purchase. Both the coolant feed and return lines to the turbo were leaking bad. O2 sensor came up faulty, as well as PCV diaphragm. This about the 4th serious issue we’ve had with this car. I expected this upon purchasing but got one anyways to try it out for off-roading. More to come soon!
I purchased a 2022 V8 after waiting about a year to get the vehicle. It mostly has been a good car until recently. I was pulling into my garage, which has a downhill grade, and there was ice on the surface of the driveway and subsequently slid into the corner of my garage going no more than 3-5 mph. Quarter size dent on the bumper, no big deal… I thought. Tried to reverse away from the garage and the car wouldn’t move. All of the warning lights appeared. I was able to finally get it to reserve but every time I would put it into drive from there, the parking brake would turn on and the brakes would lock up. I had it towed to a Land Rover dealership and apparently the entire ABS module has faulted. They ordered a new one and installed it only to find out that it still isn’t working properly. Land Rover says this isn’t covered by warranty as it isn’t a manufactures defect. I’ve now had to spend $10k and still don’t have a fully functioning vehicle. How could a $110k “off road machine” be put to a stand still due to a quarter size dent incident in the bumper, let alone the ABS module is located in the engine bay! Incredibly frustrating and can’t wait to get it fixed and sel it; if I can even get it fixed properly. I am taking it to another Land Rover dealership in town as the other one seemed incapable of figuring it out. Land Rover USA has been horrible to work with and I am now driving a vehicle with a vibrating sensation in the brakes and maybe 50% of the normal braking power.
My vehicle had been at the Land Rover South Bay Service department from 11/3/21 to 11/10/21 because the suspension fault indicator had come on the prior week and the air suspension had temporarily failed. In addition, it occasionally does not start when I press the start button with my foot depressing the brake pedal and the key is in the car. It is a brand new vehicle with about 1,750 miles. On 11/11/21 I was driving the vehicle down a hill at approximately 40-45 MPH when the automatic emergency braking system self activated for no reason. The vehicle came to a rapid, abrupt stop and the closest vehicle in front of us was at least 20 yards ahead. There were no obstacles in the road. Luckily, there was no vehicle following me or we would have been rear-ended. There was a red hazard signal with a red exclamation mark that appeared on the display near the speedometer and an audible alarm sounded. I immediately brought the vehicle back to the Land Rover Service department and they did a "scan". They informed me that they did not detect any faults or any history of a problem. I love this vehicle but I am now obviously concerned about driving it. I informed the dealership that if this happens again I will return the vehicle and request a refund.
