2020 Land rover Defender

Our 2020 Defender's halo light on the driver's side has become inoperable & poses a safety hazard. After researching this issue, it appears that this has been reported widely online. This malfunctioning halo light renders overall lighting very dim at night, creating a safety hazard for my vehicle & other drivers on the road. While looking online this is a rampant problem with this model, with the dealers wanting to charge & exorbitant cost of $4K+ I am writing to request that the manufacturer assume full responsibility & costs for repairing this safety related lighting defect at a local dealership. Properly functioning exterior lighting is an essential safety feature of any vehicle. This malfunction affects my visibility. We purchased this vehicle with the reasonable expectation that critical safety equipment would function properly & that the manufacturer would stand behind defects involving safety issues. I believe it is unreasonable for me to be expected to bear the cost of diagnosis, parts or repair as this is an inherent lighting system issue. I am therefore requesting that the manufacturer cover 100% of all costs. This is a safety issue, not a cosmetic concern & I strongly urge the manufacturer to treat it accordingly. The halo light has been out for a few weeks; there were no warnings that the light was out just noticed dim lighting & neighbor while passing on the road mentioned it.

I own a 2020 Land Rover Defender 110 HSE, and both of the vehicle’s daytime running lights (DRLs) have failed. The first DRL failed at approximately 63,000 miles, and the second DRL failed at approximately 68,000 miles. This appears to be a known and recurring issue with the DRL/signature lighting system on 2020 Land Rover Defenders, yet these failures commonly occur outside of the vehicle’s original warranty period, leaving owners responsible for extremely expensive repairs or replacement of an entire headlight assembly for what appears to be a failure of a small electronic component. This is a safety concern, not simply an aesthetic or convenience issue. When one of the signature DRLs fails, the lighting appearance of the vehicle can make it appear as though a headlight or other required exterior light is not functioning properly. This can make the vehicle less conspicuous to other drivers and can also result in confusion or concern from law enforcement. A vehicle with one side of its DRL signature illuminated and the other side completely dark can appear to have a lighting malfunction, potentially resulting in the driver being pulled over or cited. The fact that both DRLs on my vehicle have now failed independently at approximately 63,000 and 68,000 miles is particularly concerning and suggests a recurring component or design defect rather than an isolated failure. Owners should not be expected to replace an entire headlight assembly at significant expense because of a predictable failure of the DRL electronics. I am requesting that NHTSA investigate the frequency and cause of DRL failures on 2020 Land Rover Defenders and determine whether a safety-related defect exists and whether Land Rover should be required to provide a permanent remedy, particularly given that these failures can occur after the original warranty has expired. I am also concerned about the potential impact of this recurring failure on vehicle inspection and registration requirements.

Driving and the steering assistance warning goes off cuts off my cruise control and my lane keep assistance causing my car deceleration on highway promptly while going 70 mph.

The contact owns a 2020 Land Rover Defender. The contact stated that while operating the vehicle, the check engine warning light illuminated, and the vehicle was driving roughly. The contact stated that the vehicle hesitated while accelerating and the vehicle felt as if the brake pedal was being depressed. The vehicle was taken to the local mechanic, and the contact was informed that the coolant hose attached to the radiator and the coolant pipes needed to be replaced. The vehicle was repaired; however, the failure reoccurred approximately one month later. The front driver’s side headlight had failed and was replaced by the local dealer. The contact stated that one month later, the front passenger’s side headlight failed. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 40,000.

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.

Daytime running lights on my car gave out. This has been an issue with 2020+ Defenders as the LED module burns out overtime due to a lack of sufficient cooling. Land Rover quoted over 5000 dollars for headlight replacements just for a simple LED bulb. This needs to be addressed.

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 driver-side headlight assembly failed unexpectedly on my 2020 Land Rover Defender 110. This appears to be a known and recurring issue with this vehicle model involving the headlight or related electrical/control system. The failed component and vehicle are available for inspection upon request. The failure significantly reduced nighttime visibility and made the vehicle less visible to oncoming traffic and other drivers. Operating the vehicle with only one functioning headlight created a hazardous driving condition, especially during nighttime driving, adverse weather, and on poorly lit roads. This increased the risk of an accident for myself, passengers, and other motorists. The issue was reproduced and/or confirmed by the dealership/service center after inspection. The failure appears consistent with similar complaints reported by other Defender owners regarding headlight malfunction issues. The vehicle/component has been inspected by the dealership/service center. No inspection has been conducted by police or insurance representatives at this time. There were no warning lamps or messages prior to the failure.

While I was driving, the vehicle shut down unexpectedly. I was sliding sideways across the road on ice on the side of a cliff and luckily was able to stop the vehicle before going off the side of the mountain. I had to entirely restart the vehicle to begin driving again.

I am reporting a systemic failure of exhaust manifold retaining bolts on the 2020 Land Rover Defender (L663, P400 engine). While removing the engine skid plate, I discovered a fractured exhaust manifold bolt that had fallen down. The bolt head had separated, leaving the threaded portion in the cylinder head. There are I believe 12 manifold bolts securing the integrated exhaust manifold/turbocharger assembly, & multiple owners have documented similar failures, including cases with multiple broken bolts on one vehicle. The exhaust manifold is integrated with the turbocharger and is part of the emissions control pathway. This assembly operates at extremely high temps. Based on the pattern of failures, repeated thermal cycling and inadequate fastener material appear to cause bolt fatigue and fracture. When bolts break, proper clamping force is lost and hot exhaust gases escape directly into the engine compartment rather than remaining sealed within the manifold/turbo assembly. This presents serious safety concerns: Fire risk: Escaping exhaust gases from a turbocharged engine can exceed 1,000°F. These gases are released near wiring, plastic components, insulation, and other materials. Loss of sealing increases the risk of localized overheating and engine compartment fire. Exhaust gas intrusion: Exhaust leaks at the manifold can allow exhaust gases to enter the passenger compartment. Emissions defect: As this leak occurs upstream of emissions control components, unmetered exhaust gases escape before entering the emissions system, affecting federally regulated emissions compliance. This costs thousands to fix and owners are going to ignore it due to cost & unawareness. Multiple vehicles across varying mileages have experienced this issue, suggesting a systemic design or material defect rather than normal wear. Exhaust manifold fasteners should not fracture under normal operating conditions on a vehicle with 30,000 miles.

We have had our vehicle for 3 years and had to replace our windshield twice from random cracks starting from the exterior windshield where it meets the body of the care. It has happened on its own, twice, which impact from any object. The cost of the windshield, as installed is over $2000 each time, and it is repeated occurrence with owners.

The DC to DC converter for the Hybrid 48v Electrical system has failed. This puts the vehicle at risk of a fire. The part is backordered for a significant amount of time, and there are many others in this situation.

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.

The Daytime Running Lights (DRL) stopped working. The biggest hazard of DRL failure in a 2020 Defender is reduced daytime visibility to other drivers, which increases accident risk, especially in marginal light conditions. Also, in the Defender, DRLs are LED-based and integrated into the front lighting assembly. A failure could point to wiring, control module, or fuse issues. If ignored, these could eventually affect other lighting systems. The issue has been reported to JLR and I will be taking the car to the dealer for formal diagnostics and report.

Mileage at time of failure: ~27,500 miles The signature LED headlamp assembly on my 2020 Land Rover Defender 110 X has experienced a failure of the integrated Daytime Running Light (DRL) module. The DRL has gone completely dark and is no longer functioning. This failure occurred shortly after the expiration of the factory warranty and affects a key visibility and safety feature of the vehicle. The only available repair, according to the dealership, is full replacement of the headlamp assembly at a cost of over $3,000. The DRL cannot be serviced independently. This is an unreasonable cost for a low-mileage vehicle and a safety-critical component. This appears to be a widespread issue affecting 2020–2022 Defender models, with numerous reports online from other owners citing identical DRL failures. This suggests a systemic design or quality defect in the headlamp assembly. A DRL failure undermines the vehicle’s visibility to other drivers and reduces safety during daylight driving. Given the high cost of repair and the frequency of reported failures, I believe this defect warrants investigation and potential recall action.

The LED daytime running light failed on my vehicle and the dealer needed to replace the entire headlight unit. The manufacturer wanted to charge $2,500 for the replacement. There must be something faulty in the design of these headlights as out of 156 people I surveyed with Defenders, I’ve heard of 55 who have had this same issue, 7 who have had their daytime running light and headlight fail, 87 who have not had the daytime running light issue yet, and 7 respondents do not have the LED headlights and have not had their daytime running issue. This seems to be a manufacturer defect.

The daytime running lights which also dim the overall lights at night, also known as the halo LED light continues to malfuction. I bought this car (2) years ago and I'm now on the second set up LED running lights. There are numerous other reports of this malfunctioning across owners. multiple online forums. this overall poses a large saftey hazard as the light is very dim at night from it not running, also including the daytime light casuing saftey issues for other cars.

2020 Land Rover Defender with air intake snorkel was detached from the vehicle driving down the highway during a windy day. I see that Land Rover has recalled the snorkel for 2023 and 2024 models for that very reason. The recall should include 2020 models as well! I've noticed that there are many Land Rover Defender owners talking about this same issue online.

This is a 2020 Land Rover Defender 110. The daytime running lights on the headlamp need replaced. I had replaced the passenger side a few months ago at the Land Rover dealership while the car was still under warranty at 49,500 miles. Now, the Land Rover has 55k miles and the driver side has gone out and the Land Rover Dealer has quoted me 3K to fix this. This is a common problem and many owners with the years 2020-2023 are experiencing the same problem. This should not be happening with LED lights with such low mileage on the Defenders. This is a safety issue and this model should be recalled. Yes, the dealer has confirmed the problem with the daytime running light on the headlamp. There were no warning lamps or messages with this failure.
