What's wrong?
The engine control software in the 2017 Chrysler Pacifica with the 3.6L engine is the program that tells the engine when to fire fuel and spark. It reads the crankshaft position sensor, which tracks the crankshaft as it turns. That timing signal helps the engine stay running in the correct sequence.
On affected Pacificas, the software can lose synchronization with the crankshaft position sensor. When that happens, the engine control module no longer has the timing information it needs to keep combustion steady. The result is an engine stall, and the revised software is designed to help the engine recover from that loss of synchronization.
There is no warning sign before failure. The stall can happen without a warning light, sound, or rough-running symptom first, so an owner should not rely on a symptom to know the software has lost synchronization.
Who's affected?
The recall is scoped under 2 component categories for the same vehicle: electrical system software and engine.
| 2017 Chrysler Pacifica | electrical system software |
|---|---|
| 2017 Chrysler Pacifica | Engine |
| Units affected | 153,859 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific minivan is included.
What's the safety risk?
An engine stall can happen without warning and increase the risk of a crash. If the engine loses power, steer to a safe place, stop, and contact the dealer. Schedule the software update soon so the engine control system gets corrected. Repair is free at any franchised Chrysler dealer.
What should I do?
- Check your VIN to confirm your 2017 Chrysler Pacifica is included in this recall.
- Contact a franchised Chrysler dealer to schedule the free engine-control software update that addresses the crankshaft sensor sync issue linked to engine stalling.
- Bring the recall notice if Chrysler mailed one. If not, reference recall number 18V049 and Chrysler recall U01 when you call.
- Drive cautiously until the software update is complete, and leave extra space in traffic in case the engine stalls.
What happens at the repair
At the dealer, a Chrysler technician updates the engine control software so it stays synchronized with the crankshaft position sensor. The software update and labor are free under the recall. If you already paid out of pocket for a related engine control software or stall repair before the recall notice, FCA US has a reimbursement process. Follow the owner letter instructions and send the original receipt or other proof of payment to FCA US for expense confirmation.
