by Massive Jaguar Land Rover recall due to DCDC converter failure
Vehicle recalls are never pleasant. It is especially unpleasant when they cover about 35 models and over 170,000 vehicles. Jaguar Land Rover is currently facing exactly this situation, all because of a DCDC converter in some of the brand’s most popular SUVs.
The bad news is that the fault can leave drivers stranded. The good news is that they will at least get a warning before it happens. The unpleasant news is that JLR has not yet found a solution.
Which models and model years are affected?
The recall covers 170,169 vehicles manufactured from 2019 to 2024, including all models from the Range Rover and Range Rover Sport to the Defender, Velar, Evoque, Discovery, as well as the Jaguar F-Pace and E-Pace. It is important to note that this only applies to vehicles with a mild hybrid transmission. Documents filed with the NHTSA explain what happens when the DCDC converter fails.
How does the fault manifest?
A faulty converter cannot charge the 12-volt system. This is similar to how a faulty alternator would fail to charge the battery in a conventional internal combustion engine vehicle. Initially, drivers receive a red warning: “Stop safely — electrical fault detected.” If ignored, the situation worsens: driver assistance systems shut down, suspension errors appear, and eventually, the vehicle may shift itself into neutral. If you continue driving, the engine stalls. Shortly after, even the exterior lights may go out.
Reaction from JLR and regulators
Jaguar Land Rover reports that it has already recorded nearly 6,000 field reports related to this issue in the US alone. Despite this, the company initially determined that the problem did not pose a safety risk due to the gradual onset of symptoms. However, regulators disagreed. The NHTSA reviewed the situation and made it clear to JLR that this is indeed a safety problem. This is how the recall came about.
Notably, there have been no injuries, accidents, or fires associated with this defect so far. At the same time, owners are unlikely to be pleased by the news that no solution currently exists. This is a rather unpleasant situation for buyers of luxury vehicles who paid a considerable amount of money for these SUVs.
Although JLR does not yet offer a specific fix, owners of affected vehicles should pay close attention to warning signals on the instrument panel. The situation highlights how complex modern cars with hybrid systems have become, where even a minor electronic fault can lead to serious consequences. The company is expected to develop a software update or component replacement soon to eliminate the risk. Meanwhile, regulators continue to pressure the manufacturer to ensure the safety of drivers and passengers.
