Electrical faults can lead to loss of power and exterior lighting. Recall affects multiple Jaguar and Land Rover models from 2019 to 2024. No fix is available yet as regulators push JLR to address safety risk. Recalls are never good. Those that affect some 35 models and over 170,000 vehicles are particularly rough. Nevertheless, that’s exactly what Jaguar Land Rover is dealing with, and it all comes down to a DCDC converter in some of the brand’s most popular SUVs. The bad news is that the fault could strand drivers. The good news is that at least they’ll get some warning before that happens. The ugly news is that JLR hasn’t figured out a remedy yet. More: Another Month, Another Jaguar I-Pace Recall, Yet Again Over Fire Risk The recall covers 170,169 vehicles built from 2019-2024, including everything from the Range Rover and Range Rover Sport to the Defender, Velar, Evoque, Discovery, and even Jaguar’s F-Pace and E-Pace. Importantly, this only affects vehicles with a mild hybrid drivetrain. Documents filed with the NHTSA provide insight into exactly what happens when the DCDC converter fails. A failed converter can’t charge the 12V system. That’s similar to the way that a failed alternator would fail to charge a battery in a normal combustion vehicle. First, drivers get a red “Stop Safely Electrical Fault Detected” warning. Ignore that, and things escalate. The driver aids shut off, suspension faults pop up, and eventually the vehicle can shift itself into neutral. Keep going, and the engine dies. Not long after that, even exterior lighting can go dark. Jaguar Land Rover says it’s already logged nearly 6,000 field reports tied to this issue in the U.S. alone. Despite that, it initially determined the problem wasn’t a safety risk because of how gradually the symptoms appear. That said, regulators didn’t agree. The NHTSA reviewed the situation and made it clear to JLR that this was indeed a safety problem. That’s how this recall ultimately came about. Notably, there aren’t any injuries, crashes, or fires tied to the defect at this point. At the same time, owners probably won’t be stoked to hear that there isn’t a fix available at this point. That’s a rough deal for luxury buyers who paid top dollar for these SUVs.
