Chrysler Pacifica Plug-IN Hybrid Recall 20V334: Loose 12V battery post can overheat and cause fire

NHTSA campaign 20V334, reported June 9, 2020, 23,079 vehicles potentially affected.

What this recall means for you

A connection at the 12-volt isolator post, located behind the driver's seat, may develop high resistance. That resistance can make the connection overheat, creating a risk of fire whether the vehicle is running or turned off.

Until the final repair is available, do not park these vehicles inside a building or structure, or near other vehicles. Keep liquids out of the rear seat area, including beverages, wet items, umbrellas, or bottled liquids that could leak onto the connection.

The remedy is free at an authorized dealer. Dealers will first perform an interim inspection of the joint; if it is compromised, you will receive a loaner vehicle while a final fix is developed. The final remedy will increase torque on the post, add a waterproof gasket, and inspect for contamination, replacing the post and cables if needed. Check your VIN for open recalls, or call FCA US LLC customer service at 1-800-853-1403 (recall W46).
