Owner Narrative
My 2021 Chrysler Pacifica Hybrid has a recurring hybrid/electrical defect that causes the accelerator to lose all power while driving, leaving the vehicle unable to accelerate or respond to throttle input. The vehicle remains âon,â but it cannot move under its own power and must be coasted or pulled over immediately. This has happened in traffic, including with children in the vehicle. The dealer confirmed fault code P1A21â00 and documented that the highâvoltage system can lose its loop connection, which results in a noâpropulsion condition. They also found the HVIL highâvoltage connector loose and damaged. The vehicle was in the shop for 18 days for this issue. I picked it up on June 18, 2026, and within 24 hours the same lossâofâpropulsion failure happened again. The vehicle is now back at the dealer. The dealer performed recall 52D and updated the BPCM software, but the failure still occurred immediately after pickup. This defect has been reproduced and confirmed by the dealership multiple times and remains unresolved. This is a serious safety hazard because the vehicle loses propulsion without warning and cannot accelerate in traffic.
