NHTSA Complaint #11714705 — 2023 LAND ROVER DEFENDER

I own a 2023 Land Rover Defender 130 that I purchased brand new. Since buying it, it has been back to the dealer many times for serious issues. The vehicle has had repeated cooling system failures, including replacement of all upper coolant hoses. Most recently it was at the dealer for coolant loss / no coolant, and the dealer diagnosed failed O-rings going into the turbo and repaired it. I was told this is a common issue but there has been no recall. Shortly after getting the vehicle back, while traveling with my family, I received a dashboard warning: “Stop safely – electrical fault.” Immediately after this warning, the vehicle lost power and died in the street with my family in the car, creating a major safety hazard and risk of being hit by traffic. The vehicle had to be towed. I am currently stranded in NY (away from home in MA) and the vehicle is now at a dealer here. It has been difficult to even get it seen by a technician, and we are supposed to return home tomorrow (Sunday). I have learned many other owners are experiencing similar “Stop safely” failures and it appears related to the P400 DC/DC converter. There have also been incidents where the steering wheel would not turn, and the only way to restore function was disconnecting the negative battery terminal to reset the vehicle computer, which is extremely dangerous. Additionally, the heated steering wheel overheated and burned a hole through the steering wheel and burned my hand while driving. The dealer replaced it under warranty, but the repair notes suggested the damage caused the heater issue, when the damage occurred because of the overheating/burn. This vehicle has had repeated safety-related defects involving the cooling system, electrical system, steering, and heated steering wheel, including sudden shutdown in the roadway with passengers. I request NHTSA investigate for a potential recall.
