What Happened
Your vehicle's rear axle may have a problem with the pinion nut not being properly secured, which could cause it to come loose over time.
Risk if Unfixed
If this happens, you could lose control of your vehicle and crash, with little warning, and that could be very dangerous.
Free Fix
Chrysler will fix this for you free of charge by installing a new part to keep the pinion nut in place, and they'll contact you when it's time to bring your vehicle in.
