2018 Chrysler Pacifica electrical system problems

“I originally took my car to Reedman toll in 2021 due to frequent issues with the batteries needing to be replaced and the car not starting. At the time I was told it was related to a recall, and they fixed it. However, over the last year I have continued to have various problems with the car. The batteries were replaced numerous times. The check engine light and stop start unavailable light going on randomly. The car also started having electrical issues like the radio would just turn off on its own, or the automatic car doors would not open. The car also started feeling jumpy and shaky upon starting, and when the car is off there is a thumping noise. This thumping noise is still heard when the car has been off and parked for hours. The car will be off and I will get in it and hear the thumping before the car starts. Over the summer the problems became more frequent, and on August 31st it would not start, and I had to have it towed to Reedman. Reedman said my started was bad and also the fuse box shorted. They had my car for 10 days, and during this time I paid $500 out of pocket for a rental. I paid $2000 to Reedman for these repairs. I got the car back, and…”

“My van has been reliable for 5 years until recall 73B was performed. Ever since it's install I have had 7 repair attempts and 250+ days out of service. Each repair attempt is preceesed by check engine lights, service hybrid system, check electronic throttle control, red wrench, blind spot temporarily unavailable, (occasionally) service airbag, service shifter, and stability control lights. Chrysler has been unable to fix this issue. They have replaced the abs module, 12v battery, can bus's, wiring, battery coolant heater, eflite motors and reducers, 400v battery, and the under hood wiring harness. Engineering has been involved, star cases opened, and technicians flown in to address these issues. The DTC code scans reveal many communication codes, both active and permanent. The last scan had 23 active codes. No one can tell me if this van is safe to drive, I don't think it is. I have had no drive events, and lost power steering momentarily at highway speeds. The latest incident had the messages start appearing at 45 mph. This can is unfit to be on the road, and stellantis does not seem to be able to fix it”

“An Electric Power Steering System (EPS) code came up on the dash and then it locked up the steering going down the road with my wife and children in the car on 10-13-2026. Bought the car from a dealer on 10-12-2026. Replaced main and auxiliary batteries on behalf of dealerships expense on 10-14-2026. 10-16-2026 the code came back up and locked the steering up again going down the highway with my wife and children in the car. The dealer is taking action as we speak, we will see what they do.”

“The transmission shifts harshly, clunks when shifted into Drive or Reverse, and hesitates before suddenly lurching. Engine RPM rises before the transmission engages, and some describe the resulting jolt as feeling like being hit from behind. The steering wheel locks stiffly during gentle turns to the right, then suddenly releases causing a jolt back to the left at times, all other times it requires a hard pull of the wheel manually to get the steering to release, which also causes a hard jerking to the opposite direction. Battery and stop/start system: Repeated Auxiliary battery replacements which power the stop/start system and warning lights. On 5 occasions the Aux battery has been replaced and within a week the system fails with no diagnostic readings identifying the cause. This leads to harder drains on the main battery. The main battery (purchased from Autozone, has been replaced on warranty because it never makes it past the 2-year mark) occasional starting difficulties, and inconsistent stop/start operation. Dash Screen: The screen freezes or turns blank while operating the vehicle. Complete loss of cabin temperature control. At other times the display…”

“The steering wheel of my 2018 Chrysler Pacifica sticks when I turn to the left (around 10-11 o'clock) and to the right (around 1-2 o'clock). Going about 40 miles per hour I can take my hands off the wheel and the steering will continue to stay locked in that position until I push it out of that locked position. I still own this vehicle as it is our family vehicle. If you are a driver that allows the steering wheel to turn itself back straight and not realize that it sticks, this could cause an accident. Even forcefully turning back causes an over correction and it is getting worse. Have not gotten it inspected yet. This issue just started within the last 2 weeks, August/September 2026. There are no warning lights. Main battery has no corrosion. Vehicle has 96,966 miles on it. Seems related to -- NHTSA CAMPAIGN NUMBER: PE25009”

“While driving my vehicle at approximately 75 MPH on the interstate the steering wheel froze/stuck while executing a long sweeping curve. The steering wheel would not turn and my wife whom was drivng was applying excessive pressure to the steering wheel to keep the vehile from running off the shoulder of the road almost lost control of the van when the steeringwheel broke loose and over corrected and the van made a sudden, sharp turn. This occured during an essentual 2 hor drive to a medical appointment. This vehicle matches the exact failure criteria currenly under active investigation by the NHTSA under PE25009 for steering binding. The manufacturer (Chrysler) refuses to honor or repair this known defect under warranty creating a sever and immediate hazaard for families operating these vans at highway speeds.”
