What's wrong, in plain English

The service and owner's manuals for these trucks contain incorrect torque information, which can cause the wheel lug nuts to be tightened too much. Over-tightening the lug nuts this way can break a wheel stud, and a broken wheel stud can allow a wheel to come loose from the vehicle.

What you should do

1. Check your VIN at nhtsa.gov/recalls. 2. Contact a dealer, or call FCA US customer service at 1-800-853-1403. 3. The torque specification will be corrected and wheel studs inspected, and replaced if necessary, free of charge.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 21V398000.
