Typical fuel system symptoms owners report
- Vehicle stalls or loses power suddenly at low or highway speeds with no warning light, often leaving the driver stranded in traffic.
- After stalling, the engine will not restart, and the gear selector cannot be moved to neutral, blocking roadside towing.
- Owners tie the stalling to failure of the fuel pump power control module, the same part named in recall 21V739000.
- Some vehicles show a check engine light with rough idle or hesitation before the engine cuts off entirely.
- A few owners report the stall happened multiple times and required dealer replacement of the fuel pump control module under warranty.
- One owner reported the vehicle would not shift out of park after the engine shut off at 55 MPH, tying the failure directly to the recall campaign.
