2023 Land Rover Defender

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.).
