Jaguar Land Rover has issued a massive recall affecting more than 170,000 vehicles in North America.
The issue is serious.
Affected vehicles could suddenly lose power while driving.
And right now, the company admits it still doesn’t have a fix ready.
What’s Causing The Problem?
According to documents filed with NHTSA, the issue stems from a faulty DC-DC converter.
More specifically, a problem with the converter’s boost control microchip can trigger failure.
When that happens, drivers may first see a warning message that reads:
“Stop Safely Electrical Fault Detected.”
That warning reportedly appears roughly 10 seconds before the situation gets worse.
What Happens If The Failure Continues?
If drivers keep moving after the warning appears, the vehicle can begin shutting down critical systems.
That includes:
- Lane-keep assist warnings
- Stability control warnings
- Suspension warnings
Eventually, the vehicle can shift itself into neutral.
From there, it may coast to a stop.
The center screen can shut off.
Air conditioning may stop working.
The engine can shut down completely.
Even exterior lights may eventually fail.
Which Vehicles Are Affected?
The recall impacts several Jaguar and Land Rover models:
- Land Rover Range Rover Velar
- Land Rover Range Rover Evoque
- Land Rover Range Rover Sport
- Land Rover Range Rover
- Land Rover Discovery Sport
- Land Rover Discovery
- Land Rover Defender
- Jaguar I-Pace
- Jaguar E-Pace
JLR Originally Didn’t See It As A Safety Risk
JLR first began investigating the issue in September 2024.
At the time, the automaker reportedly viewed it as more of a customer satisfaction issue than a safety concern.
That changed after additional reports surfaced.
NHTSA later pushed back and classified the issue as a safety problem.
Between July 2019 and April 2026, JLR says it received nearly 6,000 reports tied to DC-DC converter replacements.
There’s Still No Fix
That’s arguably the biggest issue here. JLR says it’s still developing a remedy.
Owners will be notified once a fix becomes available.
For now, drivers of affected vehicles may want to pay very close attention to warning messages, because losing power and exterior lights at speed is about as serious as recalls get.
