2020 Land Rover Defender Complaints

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 pres...

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.
