2020 Land Rover Range Rover problems

Sun roof drains failed flooding the car and destroying electronics in the passenger wheel well. This is a problem that happens with every single L405 ever produced and the manufactures answer for it is a complete replacement of the sunroof and insert. The cost of the repair will mechanically total a vehicle that's as little as five years old. The actual solution is 3.5 hours of labor and less than $100 of parts but its not acknowledged by Land Rover simply because every L405 in existence will eventually have this exact failure that is due to a poor design with dissimilar metals in a wet environment creating electrical current and causing rapid deterioration of the less noble metal (Drain Tubes). The first module to get destroyed is the audio amplifier located under the passenger seat. This part is constantly on Back Order due to the number of people experiencing this issue and is $1500. The labor to replace this item is going to triple the cost. All due to two small defective drains that they refuse to acknowledge are poorly designed.

I own a 2020 Land Rover, VIN [XXX], which is affected by the federal safety agency Safety Recall 26V‑248 / Jaguar Land Rover Recall D126. I brought the vehicle to an authorized Land Rover dealership after the check-engine light illuminated. While the vehicle was at the dealership, I requested that the open D126 safety recall also be performed. The dealer informed me that they could not perform the recall software update because my 12-volt battery is “almost failing” and told me that I would first have to pay out of pocket to replace the battery. I am concerned about this because Recall 26V‑248 specifically involves the vehicle’s DC-DC converter and insufficient electrical load balancing. According to the recall, a failure of the DC-DC converter can result in loss of 12-volt system charging and can ultimately cause loss of motive power and exterior lighting I did not bring the vehicle to the dealership because of a dead battery or because the vehicle would not start. I drove the vehicle to the dealership because the check-engine light had illuminated. The dealer is effectively requiring me to purchase a 12-volt battery before they will perform the open safety-recall remedy. I have asked for documentation showing the battery test results, the diagnostic trouble codes associated with the check-engine light, and the manufacturer procedure explaining why the existing battery prevents the dealer from performing Recall D126. I am concerned that the condition of the 12-volt battery could potentially be associated with the charging-system defect that is the subject of this recall. I do not believe I should be required to pay for a component potentially affected by the recalled charging-system condition simply in order to obtain the federally mandated recall remedy. I am requesting that the federal safety agency review whether Jaguar Land Rover and/or its authorized dealer may require an owner to purchase a replacement 12-volt battery as a condition of performing Recall 26V‑248, particularly whe INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

**Component/System:** 48V Mild Hybrid Electric Vehicle system, including the DC/DC converter subject to JLR recall D126, MHEV battery/Battery Energy Control Module, starter generator/alternator system, 12V charging system, telematics control module, and related vehicle communication/electrical modules. The vehicle and components are available for inspection upon request. **Description of Complaint:** My 2020 Land Rover Range Rover P400 MHEV, VIN [XXX], experienced serious electrical and high-voltage/MHEV system failures involving the 48V mild-hybrid system and DC/DC converter system. Before the original failure, the vehicle displayed the warning message **“High Voltage Shutdown Not Possible — System Live.”** The warning would appear on the instrument cluster while driving. The vehicle later displayed **“Stop Safely — Electrical Fault Detected.”** The vehicle then shut down while in operation, and steering assist was lost/steering became locked or extremely difficult to control. This created a serious safety risk because the vehicle lost power/drive functionality and steering assistance while being operated. The vehicle was taken to Jaguar Land Rover Parsippany for the D126 DC/DC converter recall/interim repair. The DC/DC converter is part of the 48V MHEV system and manages power transfer between the 48V and 12V electrical systems. After the D126-related repair, the vehicle would not start at pickup and had to be jump-started. The dealer later diagnosed a telematics control module issue/parasitic draw, but the vehicle continued to have electrical and high-voltage warnings. After the interim DC/DC repair, the **“High Voltage Shutdown Not Possible — System Live”** warning returned while driving. The malfunction indicator/check engine light also came on.
