Example complaints

“Driving along when electrical warning light came on and car died. Coasted into safe parking space. Would not start. Dash controls would not respond. This is the day after we bought it. It had been on trickle charge at the dealership and drove fine the evening we bought it. It was fine driving in the morning. So the battery should have been fully charged.”
NHTSA complaint #11765553, filed 2026-09“My instrument cluster will dim to a nearly unreadable level at random times during the day. This appears to be a common and documented issue with Land Rover Defenders. I have seen a multitude of forum posts going back several years about this issue. There are no settings in the system that allow me to adjust this or prevent it from happening.”
