2023 Land Rover Defender Exterior lighting Problems

I am reporting a suspected systemic safety defect involving premature failure of the integrated LED daytime running lights (DRLs) on 2020–2026 Land Rover Defender (L663) vehicles. The DRLs reportedly fail at relatively low mileage, frequently around 50,000 miles, during normal vehicle operation. The suspected cause is overheating and premature deterioration of the integrated LED driver electronics due to inadequate thermal management. The precise cause requires investigation. This failure eliminates an important daytime vehicle conspicuity feature, reducing visibility to approaching motorists, pedestrians, and cyclists, particularly during rain, overcast weather, and transitional lighting conditions. Some owners report no dashboard warning when the DRLs fail, potentially leaving drivers unaware of the malfunction. Jaguar Land Rover has known about this issue since at least 2021. Its Special Service Message SSM 75479 specifically acknowledges DRL failures on 2020–2021 Defenders and documents an engineering investigation. Similar failures have subsequently been reported by owners of later model years, suggesting a potentially unresolved design defect. Because the DRL electronics are integrated into the sealed headlamp assembly, dealerships generally require replacement of the entire assembly, costing approximately $3,000 per headlight or $6,000 for both. Land Rover reportedly provides goodwill replacements selectively while requiring other owners to pay out of pocket. I request that NHTSA investigate the entire 2020–2026 Defender population, examine JLR’s engineering records, warranty claims, component failure rates, and headlamp design revisions, and determine whether a safety recall and manufacturer-funded corrective action are warranted. This is a recurring failure of a factory-installed safety-related lighting system, not simply an ordinary maintenance or warranty concern.

I own a 2023 Land Rover Defender 110 X. The passenger-side daytime running light halo is completely inoperative. On November 2, 2026, an authorized Land Rover dealer inspected the vehicle and advised that the entire passenger-side headlamp assembly must be replaced. The quoted repair cost was approximately $3,255, plus applicable taxes and fees. The dealer also advised that the vehicle cannot pass Hawaiʻi’s required safety inspection because of the lighting failure. The original headlamp has not yet been replaced and remains available for inspection. There has been no crash, fire, injury or death associated with this failure. I believe the DRL has failed prematurely on a relatively new vehicle. Because the DRL is integrated into the sealed headlamp assembly, the failure requires replacement of the entire assembly rather than an individual bulb or serviceable lighting component. I am concerned that this premature exterior-lighting failure reduces the vehicle’s daytime visibility to other drivers and prevents the vehicle from passing its required safety inspection. I am submitting this complaint so NHTSA can document the failure and evaluate whether similar DRL failures are occurring in other Land Rover Defenders.

A warning sign appeared stating the battery was not charging (something like that). When I turned off the car, another warning said to keep the car turned on the battery was low. I kept the car on and began to drive home, very quickly more warnings appeared, power was diminished, so I pulled into a parking lot and the car completely stopped. Tried to turn engine back on to get it into a parking spot, It would not start. Could not put the care in neutral to push it out of the way. Tried to put my hazard lights on, but they would not turn on. Had it towed to a shop, they told me it was a recall, towed it to JLR (Flatirons), and there it sits. Called JLR USA, they told me not to drive it until the recall repair is made, and it looks like January 2027 is the date there will be a fix.

Without warning, the driver's side front Daytime Running Light (DRL) signature halo ring suffered a complete electrical failure while driving. The low-beam projector and high-beam lamps continue to function, but the primary forward signature DRL element is completely inoperative due to what appears to be an internal circuit/LED driver board failure within the factory sealed headlamp housing. This malfunction compromises vehicle safety by significantly degrading front-end conspicuity and visibility to oncoming traffic, cyclists, and pedestrians during daylight hours, twilight, and inclement weather. It also creates an asymmetrical forward lighting profile that can confuse oncoming drivers regarding vehicle width and lane position. Prior to the failure, there were no warning chimes, cluster warning lamps, or diagnostic messages displayed on the instrument panel or infotainment screen indicating an exterior lighting malfunction. The failure was abrupt and total. The vehicle and headlamp component have been presented to an authorized franchised retailer for diagnostic verification and confirmation of the internal circuit failure. The vehicle and original headlamp assembly remain intact and are available for inspection upon request.

My 2023 Land Rover Defender 130 X Dynamic is less than four years old and recently passed its 50,000-mile new-vehicle warranty limit. A LED daytime running light (DRL) should not fail this early. The integrated front daytime running light "halo" LED module inside the sealed premium headlamp assembly failed and is completely dark. Low/ high beams and turn lights still work, but it's not a replaceable component; the LED module's built into the sealed housing, so repair at the dealer means replacing the entire headlamp, while 90% still functions, costing ~$3,000 USD. DRLs exist to make the vehicle more visible to other drivers in daylight, dusk, rain, and glare. A burned-out halo DRL makes the front of the vehicle look uneven and can be mistaken for a headlamp that is out. There is no dash warning or message when the DRL fails, so the condition can continue unnoticed. Other drivers may not see the vehicle as soon or may misjudge its position. Inoperable DRLs can also cause a failed state safety inspection. Reduced conspicuity increases crash risk for other road users. The local Land Rover dealership service center inspected the vehicle and confirmed the premature DRL/halo LED failure, and stated they have seen a surprisingly large number of these same premature burnouts require replacement. After reviewing NHTSA records, this matches a pattern already known to the agency and to Jaguar Land Rover (JLR) NHTSA’s TSB/SSM database includes Jaguar Land Rover Special Service Message SSM 75479 (NHTSA document MC-10199802-0001), titled “Front Daytime Running Light(s) Are Not Working / Intermittent Operation.” This is not ordinary wear because LED DRLs should last far longer than 3.5yrs; that widespread pattern, plus JLR’s own internal SSM asking dealers to return failed headlamps for engineering analysis, indicates a recurring manufacturing or design problem in the sealed DRL LED module—not random bulb wear.

The front light **What component or system failed or malfunctioned, and is it available for inspection upon request?** The front passenger-side (right) headlight failed completely on my Land Rover Defender. The headlight assembly, including the bulb and/or associated electrical components, ceased functioning without any prior indication of a problem. The vehicle is available for inspection upon request. **How was your safety or the safety of others put at risk?** The sudden loss of a front headlight significantly reduced visibility while driving at night, creating a serious safety hazard for myself, passengers, and other road users. Reduced lighting also diminishes the vehicle's visibility to oncoming traffic, pedestrians, and cyclists, increasing the risk of a collision. **Has the problem been reproduced or confirmed by a dealer or independent service center?** Yes. The failure was confirmed by an authorized Land Rover dealership, which inspected the vehicle and verified that the front passenger-side headlight had failed. **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others?** The vehicle was inspected by an authorized Land Rover dealership, which confirmed the headlight failure. No inspection has been conducted by police or insurance representatives at this time. **Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear?** There were no warning lamps, dashboard messages, flickering, dimming, or any other symptoms prior to the failure. The headlight failed suddenly and without any advance warning, providing no opportunity to anticipate or respond to the malfunction before it occurred.

Daytime running lights have both failed within the last 79 days. Passenger side failed at ~32660 miles o/a 05 Mar 26. It was replaced under warranty. Driver side failed around 36234 miles on 22 May 26 (5-days out of warranty). It is pending a shop appointment for replacement. This is not a “wear and tear” issue, it is a product quality control issue. It is not a simple plug and play repair. It is a costly repair due to the design of the headlamp assembly. I have owned vehicles since 1988 and last changed a headlamp or taillight bulb in the early 2000’s and that was on a MY93 vehicle. I have also owned two other Land Rovers MY07 LR3 from 2008-2011 and MY14 LR4 from 2014-2022 and did not have to replace a single bulb in the vehicle. Point is that technology and quality have improved over the years and these headlamp/DRL assemblies should not fail with less than 36500 miles on the vehicle. This is a known issue that warrants further investigation. Jaguar Land Rover has issued a Special Service Message 75479 concerning the known issue with the Defender DRL. My DRLs failed in similar fashion described in the SSM. Inoperable DRL reduces safety due to lower visibility since they should operate during normal driving conditions. This issue is dangerous since there is no indication on the dashboard or other warning unless the headlights are manually inspected while the vehicle is operating. Additionally, inoperable DRL leads to a failed State vehicle safety inspections.

This vehicle is equipped with the "Interactive Driver Display" (IDD), which is a full digital dash. Myself and several other members of enthusiast forums have reported that with recent software updates (PIVI 4.0), this display autodims entirely too dim to see. This happens in bright, full-sun, and half-sun cloudy conditions which prevent the driver from seeing the dashboard. This presents a major safety issue, as there is way to see the speed, tachometer, fuel gauge, warning lights of any kind (including pressure, safety warnings, engine temperature, etc.).
