2022 Land Rover Defender

1) Exhaust Manifold Studs are loosening and/or breaking on I6 engine causing potential CO2 exposure to passengers in the cabin and/or engine bay fire risk. 2) Potentailly yes via CO2. 3) Yes - out of factory warranty therefore had independent service center replace all studs 4) No 5) Not in my case but others on JLR Automotive Forums have heard rattling noises and found broken bolts that fell onto the skid plate directly below engine. *) In attached images below the final picture is of the repaired studs

Headlight- warranty replacement. 4/30/2024 32,175 miles, Low Battery notification. Tested Battery- failed. Battery replacement and battery reset module = warranty replacement. 11/7/20205 58,812 miles, Turbo Coolant O rings failed- mechanical. Service writer advised this is common for these engines in the V6 defender models. Repair estimate $642.77. Dealership - provided good faith discount. Customer agreed to and paid a negotiated repair totaling $377.30. Despite all repairs, electrical warnings continued off and on with Low Battery notifications, that would appear and disappear. 1/31/2026 (62,105 mi), electrical issue, Low Battery notification, then “STOP SAFELY – ELECTRICAL FAULT DETECTED” notification. Caused vehicle failuer & shut down. Required towing. "STOP SAFELY – ELECTRICAL FAULT DETECTED" notification – electronic fault affects: Power delivery, Steering, Braking, Stability systems. Dealership Diagnosed fault code P0D33-11, failed DC/DC converter and batteries. Replacement Cost +$2,467.38. DC/DC Convertor OEM Parts are on national backorder. 1-2 months lead time. QTY 15 units waiting. Low battery warnings & P0D33-11 code are related. Weak 12V battery = stress the DC/DC converter, fault codes, conversely, a failing DC/DC prevent the 12V battery charging. These repeated low-battery warnings and electrical failures are directly related to DC/DC converter failure and represent an ongoing electrical defect that originated during the warranty period, not normal wear and tear.

Safety Complaint – DC-to-DC Converter Failure Causing Vehicle Shutdown I am submitting this complaint to report a DC-to-DC converter failure that rendered my vehicle inoperable. The authorized Land Rover service department diagnosed a failed DC-to-DC converter. This component is part of the vehicle’s electrical system and its failure caused a loss of vehicle functionality. I was informed the replacement part is on national back order, with an estimated repair time of up to two months. Based on owner reports and service discussions, this appears to be a common failure affecting Land Rover mild-hybrid vehicles. Many reports describe sudden loss of electrical power, warning messages, and vehicle shutdown. This issue presents a potential safety risk, as failure of the DC-to-DC converter can result in loss of vehicle systems and may occur without warning, including while the vehicle is in motion. The vehicle is currently unusable. It is concerning that a critical electrical component with safety implications is failing at relatively low mileage and that replacement parts are not readily available. I am requesting NHTSA review this issue for potential investigation, recall, or other corrective action.

There were two separate issues. First was the battery dying once 4 months after purchase and again about 12 months after purchase. Both times we were lucky we were not out and about 4 wheeling like we normally do. Second is very recent about 18 months after purchase. Both the coolant feed and return lines to the turbo were leaking bad. O2 sensor came up faulty, as well as PCV diaphragm. This about the 4th serious issue we’ve had with this car. I expected this upon purchasing but got one anyways to try it out for off-roading. More to come soon!

The engine cut out whilst going 90kmph on a four lane freeway. I had about 10 seconds to react before it rolled to a complete stop - it wouldn't connect the gas at all. Extremely unsafe situation, other cars beeping their horns in panic as they swerved past me. Lucky to not have caused a serious collision and die today. I ended up in between the third lane and the fourth lane exit. Waited there for 2 mins with cars going past me at full speed. Restarted and was able to take the exit where it continued to stall and eventually the vehicle was towed to the dealership. I've had the vehicle 48 hours at 325km total.

Several times while waiting at a red light, the engine just died, feels like it's connected to the hybrid engine not functioning properly. service said it had to do with battery and they fixed it. It still happened 2 more times after they serviced. Also now car is not drivable, because the steering wheel does not budge/move. Waiting for service to return my call. Is this something that could happen whilst driving? It is very scary when the brand new car keeps failing unexpectedly.
