Urgency:Safe to keep driving
Is it safe to keep driving?
Yes if it is steady. If it flashes, avoid towing and hard driving until it is checked.
Likely causes
- A drive mode engaged
- Transfer case or coupling fault
- Mismatched tire sizes stressing the system
Typical repair cost (US)
$0 – $2,000
Free if it is a mode; a transfer case actuator or coupling at the high end.
A typical range, not a quote. Actual cost depends on the car, the shop and the fault.
What to do now
- Check the drive mode selector.
- If it flashes, have the drivetrain code read.
