1 safety recall, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. The transmission sensor clusters may have insufficient crimps in the transmission wire harness, and as a result, the transmission may unexpectedly shift to neutral. On August 29, 2016 Chrysler added the 2016 Fiat 500X vehicles to this recall.
What could happen: If the vehicle unexpectedly shifts to neutral, there is an increased risk of a crash.
The fix: Chrysler will notify owners, dealers will reprogram the Powertrain Control Module and the Transmission Control Module and if necessary replace the transaxle range sensor wire harness, free of charge. The recall began on November 7, 2016. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's num…
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2016 500X.
- Book a repair at any authorized Fiat dealer. Quote NHTSA campaign 16V529000 (manufacturer code S55).

- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
