Recall 20V334 affects 23,079 2017-2020 Chrysler Pacifica Plug-In Hybrid vehicles for an overheating 12-volt isolator post. Final repair is free once available.
Chrysler is recalling 23,079 2017-2020 Pacifica Plug-In Hybrid minivans because the 12-volt isolator post behind the driver's seat can develop high resistance. That connection can overheat and raise the risk of a fire with the vehicle on or off, and the Chrysler dealer repair will be free once available.

What's wrong?
The 12 volt isolator post in the 2017-2020 Chrysler Pacifica Plug-In Hybrid is an electrical connection point in the battery-positive wiring behind the driver's seat. In normal operation, it carries 12 volt power between wiring assemblies while keeping the connection tight and low-resistance. That tight connection matters because electrical resistance turns current into heat.
On affected minivans, the isolator post develops high resistance at the connection. Chrysler found corrosion signs and low torque values at this post, and the root cause of the high-resistance connection was not known when the recall was filed. When resistance rises at a power connection, heat builds at that spot. In this recall, Chrysler identified interior fires that started behind the driver's seat.
There is no warning sign before failure. Do not wait for a warning light, smell, or electrical symptom to decide whether the recall applies to your Pacifica Plug-In Hybrid.

What's the safety risk?
A high resistance electrical connection can overheat and increase the risk of a fire with the vehicle on or off. There is no warning sign before failure. Keep liquids out of the backseat area and ask the dealer for the interim inspection. Repair will be free at any franchised Chrysler dealer once available.
What should I do?
- Check your VIN to confirm your 2017-2020 Chrysler Pacifica Plug-In Hybrid is included in this recall.
- Contact a franchised Chrysler dealer for the interim inspection of the 12-volt isolator post that can overheat behind the driver's seat.
- Bring the recall notice if Chrysler mailed one. If not, reference recall number 20V334 when you call.
- Park outside, away from buildings, structures, and other vehicles until the final repair is complete.
- Keep liquids out of the backseat area, including drinks, wet items, umbrellas, and bottled liquids that can leak.
- Call Chrysler customer service at 1-800-853-1403 with questions about the interim inspection, loaner vehicle process, or final repair status.
What happens at the repair
At the dealer, a Chrysler technician performs an interim inspection of the 12v isolator post joint behind the driver's seat. The final remedy is still under development. Once it opens, the dealer will increase torque, install a waterproof gasket, inspect the post for contamination, and replace the 12v isolator post and related cables if compromised. The final dealer repair will be free once available. Until that repair is complete, park outside and away from structures and other vehicles, and keep liquids out of the backseat area. For prior related repairs, FCA asks owners to send the original receipt or other proof of payment for reimbursement review.
