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.

Daytime running light failure. Making vehicle difficult to see. Dealer lists and a knows issue and and flagged as a safety concern. But refuses to repair or rectify the problem. And wants to charge over $4000 for a safety item.

My car does not fall under the VINs specified in recall N599 but is exhibiting the same unsafe conditions. At a rolling stop in traffic the car asks me to manually select a gear (while in Drive) and then shuts off the engine. The engine then will not restart and I am in unsafe conditions in intersections. I have brought the car to the dealership several times to resolve this and it continues to worsen. It has become a daily event and is now back at the delaership where they have told me it is not affected by this recall but clearly exhibits the same issue as described in that recall. This is a MAJOR SAFETY issue! The car shuts off without warning and wont restart. This is engine electrical system and transmission related. It drains the battery and leaves the car inoperable

The rear backup camera is foggy and it is not possible to see clearly while backing up. It is foggy in any weather condition, during the daylight, and at night. There are halos around lights at night in addition to the general fogginess.

Daytime running lights stopped working with no warning signs or notifications, reducing visibility.. Has been confirmed by independent service center. Circuitry in headlight is known to fail causing the daytime running light to stop without warning

2 windshields cracked within a 2 month period. Second windshield cracked about 45 days after installation with no evidence of any impact causing it. One morning I came out to my vehicle and there was a 6-8 inch crack starting at the bottom of the windshield. Have driven the same roads for 30 years and have never had issues with windshields and now 2 in a couple of months.

Windshield cracking for no reason Many occurrences in owners forum. Class action lawsuit filed. Manfature doing nothing. Windshields need to be redesigned .

Large clunking sound with shuddering of the vehicle during a turn at low speeds. Inspection revealed cracked transfer case and differential damage which could lead to loss of control of vehicle. Had part repaired at Land Rover, again malfunctioned after 1000 miles with shuddering and "skipping" of rear tires during turns. Aware of two other malfunctions of transfer case with instability during turns.
