The 2016 Fiat 500X was not in the original version of this recall — Chrysler added it on August 29, 2016, expanding campaign 16V529000 (FCA number S55) to cover 500X models with the 9-speed automatic transmission. The problem is with the transmission sensor clusters, which may have insufficient crimps in the transmission wire harness. When that connection is inadequate, the transmission may shift unexpectedly into neutral, and NHTSA warns that this increases the risk of a crash. Because the 500X was a late addition, some owners never saw coverage in the original 2016 recall coverage and may still have the repair outstanding. The 329,540-vehicle figure attached to the campaign is the total for all FCA models included, not a 500X-only count. Owner notification began November 7, 2016.

Common Symptoms

  • Transmission shifts to neutral on its own while driving
  • Car stops accelerating even though the engine keeps running

How to Fix

The correction is free at a Fiat/FCA dealer: they reprogram the Powertrain Control Module and the Transmission Control Module and, if needed, replace the transaxle range sensor wire harness. Given that the 500X was added to the campaign after it opened, it is worth verifying your VIN directly at nhtsa.gov/recalls rather than relying on paperwork from a previous owner. Chrysler customer service is at 1-800-853-1403; reference recall S55.

Common Symptoms

  • Hard 1-2 shift
  • Delayed gear engagement
  • Jerky acceleration
  • Transmission hesitation

How to Fix

Update the TCM software to the latest calibration from FCA. Perform a transmission fluid flush with the correct ATF+4 fluid. If problems persist, the valve body may need replacement.

Common Symptoms

  • Coolant leak under engine
  • Engine overheating
  • Low coolant warning
  • Sweet smell from engine bay

How to Fix

The 2.4L Tigershark engine consumes excessive oil due to the MultiAir II valve actuation system and piston ring design. Some owners report needing to add a quart every 1,500-2,500 miles.

This issue also affects: Chrysler 200, Dodge Dart, Jeep Cherokee

Common Symptoms

  • Low oil level warnings
  • Blue smoke on startup
  • Oil smell
  • Increased oil change frequency needed

How to Fix

Monitor oil level regularly between changes. FCA has issued TSB 09-002-18 for updated piston rings on some VINs. Switching to a higher-viscosity synthetic may reduce consumption slightly.
