2018 Chrysler Pacifica Electrical 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 immediately (same day) experienced the exact same problems, and then my car would not start again. When I did get it started I kept getting warnings that the engine might overheat. I got it back to Reedman and they then said it was a bad alternator and some wires were bad as well. They had my car for 2 months. I picked it up 9/30/26 and within less than 6 hours the check engine light and start stop unavailable light came on. The car started feeling jumpy again upon starting, and the thumping noise returned. This car was purchased brand new in 2018 and only has about 51,000 miles on it. I do not understand why this is all happening to a car that has such low mileage. My 2014 Nissan has never had a single problem.

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 will freeze on the Chrysler brand logo and is completely unresponsive to any haptic touch. The software just freezes. Even after complete shutdowns and time outs the display does not reset immediately. It's a coin flip if it's going to work. These problems have been ongoing since I purchased the vehicle in 2019. Dealerships have recognized them and consistently say that until Chrysler is forced to fix this the Dealerships can't do anything about it without charging me repairs/replacement.

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.

My 2019 Chrysler Pacifica Plug-In Hybrid unexpectedly rolled after being parked in my residential garage. The van has very low mileage ~60000 miles and is still under Battery Manufacturer warranty. The vehicle had been operating normally and was parked with P displayed on the instrument cluster. It remained unused for approximately 6 days. When the garage door was opened, the vehicle unexpectedly rolled several feet. I believe the closed garage door may have prevented it from moving earlier. A family member who happened to be present stopped the vehicle before a potentially more serious incident occurred. The vehicle and garage door were damaged. Afterward, the vehicle would not start/enter READY mode. The P indicator flashed, selected gear indicators flashed, and “Service Transmission” appeared. The vehicle ultimately required towing. An independent diagnostic scan identified multiple faults, including P07B5-00 (Park Pawl Position Sensor 1 Circuit Performance), P1625-00 (Park Pawl System Failure), and P0AA4-00 (Hybrid/EV Battery Negative Contactor Circuit Stuck Closed). Stevens Creek Chrysler later verified P0AA4-00 as ACTIVE. Their initial reset/weld-check procedure failed and the DTC returned. The dealer then opened Chrysler STAR Case 102963024. Chrysler Technical Assistance provided a PIN/procedure, after which the reset succeeded and vehicle operation was restored. The vehicle was subsequently road-tested and returned to me. However, neither Chrysler nor its authorized dealership has explained why a vehicle parked with P indicated was able to roll, whether the Park-related DTCs were connected to the incident, or whether the condition could recur. I am reporting this because an unexplained rollaway of a parked vehicle presents a serious safety risk. I remain concerned whether the vehicle is safe to park and whether similar incidents may affect other Pacifica Hybrid vehicles.

My vehicle has developed an intermittent and potentially serious safety-related failure. When the Engine Stop/Start system automatically shuts the engine off at a red light or stop sign, the vehicle sometimes fails to restart. At the same time, the electronic gear selector becomes locked, preventing me from selecting Neutral or moving the vehicle out of the roadway. The vehicle is therefore effectively immobilized in traffic. The only recovery method I have found is to disconnect both the main and auxiliary batteries for approximately 10 minutes, reconnect them, and then restart the vehicle. The check-engine light also comes on when the failure occurs. Both the main and auxiliary batteries have already been replaced on August 3rd, 2026, so this is not simply a matter of replacing an old battery. I brought the vehicle to the dealer on August 14, 2026 for inspection. Because I had previously been forced to disconnect the batteries to recover the vehicle, no diagnostic trouble codes were available when the dealer performed its inspection. I understand why this makes diagnosis more difficult, but the absence of codes after the system has been reset does not eliminate the underlying intermittent failure. I am particularly concerned because Chrysler has issued service information addressing closely related problems on the 2018 Pacifica, including S2008000075, concerning no-start, Stop/Start inoperative and Service Shifter conditions, and PCM bulletin 18-001-19, which addresses 2018 Pacifica conditions involving engine restart performance, battery state-of-charge performance, improper powerdown, ECU performance, and TCM/shifter communication faults. My vehicle also previously received the Y65 Engine Stop/Start campaign in 2021. Now in persistent no-start condition remaining in the failed state and can't be reset. The instrument panel powers up, the check-engine light remains illuminated, the vehicle produces a click when the Start button is pressed.

• July 19 (PM): While driving, the vehicle displayed: ◦ Service Hybrid Electric System (red wrench) ◦ Check Engine Light • July 20 (AM): All warning lights had cleared. • July 20 (PM): While driving, the following warnings appeared simultaneously: ◦ Service Hybrid Electric System (red wrench) ◦ Check Engine Light ◦ Service Electronic Stability Control ◦ Parking Brake Temporarily Unavailable ◦ FCW Unavailable – Service Required ◦ LaneSense Unavailable – Service Required I needed to find an alternate parking spot since the parking brake was not working. • July 21: All warnings cleared except the Check Engine Light, which has remained illuminated continuously since then. • July 25: Upon starting the vehicle, the following warnings returned: ◦ FCW Unavailable – Service Required ◦ Service Hybrid Electric Vehicle System ◦ Parking Brake Temporarily Unavailable ◦ Service Electronic Stability Control ◦ Service Shifter ◦ Check Engine Light Again needed to find an alternate parking spot with parking brake not working. Once again, these warnings disappeared after the next restart, with only the Check Engine Light remaining. Took car to dealership for service. Expected issues had to do with recall work that was completed earlier in the month. They said it was not and that the it was due to loss of can c bus communcation because the star connector failed.

Yes, the problem has been reproduced by the technician. When you put the car in reverse, it would start to go in reverse and as soon as you let off the throttle or the gas pedal, it would go forward at 15 to 20 mile an hour as you slammed your other foot on the break that’s without you even touching the gas pedal. I was sitting in a stoplight and all of a sudden the car wanted to go 55 mile an hour. And I had to slam on the brakes to keep from hitting other cars. Right immediately after that when I was trying to find a place to pull off the highway the car by itself decided to slam on the brakes or at least that’s the feeling that it gave because while I was trying to go to the car come to an abrupt stop right in the middle of the highway. Through all these different scenarios the thing that happened happened while I was not touching the gas pedal. This is why I feel like it’s a major safety concern not only for me and my family but other families that are out there driving also for everyone else that has bought this car and has the potential for the same thing to happen to them and they may or may not know what to do in that situation . We had the vehicle towed to Shottenkirk Chrysler dealership, where between Chrysler and the dealership we have not been able to come to a resolution on this vehicle!

While driving, the vehicle unexpectedly shut off without warning. The engine stalled while the vehicle was in motion, causing an immediate loss of acceleration and power. This created a serious safety hazard in traffic. The issue is consistent with the condition described in Safety Recall U01 for 2017 Chrysler Pacifica vehicles involving the Powertrain Control Module (PCM). However, this vehicle's VIN is not included in the recall despite exhibiting the same symptoms.

We purchased this 2018 Chrysler Pacifica Hybrid about a year ago from a dealership in Florida, and the vehicle is now located in [XXX]. The issues involve a malfunctioning high‑voltage hybrid charging system/battery and a possible steering or suspension component failure. For now, the vehicle has been under dealer inspection since XXX. Our family’s safety is at risk due to a charging failure in which the vehicle consistently stops charging after reaching 2–3 bars when plugged. I must unplug and reconnect the charger multiple times to resume charging, and this behavior occurs every time the vehicle is charged now. Last week, when the vehicle was fully or nearly fully charged, a “rotten egg” odor entered the cabin, especially in the middle and rear seat area. The smell consistently appeared only after charging and was concentrated near the area where the high‑voltage battery is located. Prior to these failures, the only warning was an intermittent Check Engine Light. Another issue, we also experience a metallic spring‑like noise during hard turns in both forward while parking. As of the dealer’s initial observation on XXX, their notes state: “Electrical System – replace battery. Repair – Found battery is the incorrect one installed in the vehicle for an EV system. On the van not charging fully. Chrysler corporation is aware of the issue and is working on a technical service bulletin/possible recall by the end of the year. That needs to be complete first before tech would advise that the customer’s charging cable is not working properly.” As i understand, we need to change other small battery with right specifications. Although there are currently no open recalls on our specific vehicle, the electrical burning odor has left us extremely concerned for our safety.

There was nowhere for me to pull over and the vehicle immediately shut off attempted to restart several times over the next 15 minutes, unable to restart nothing no power whatsoever called for a tow truck 40 minutes later due to the children in the car tow truck was not able to tow asked me to try and start again which I did and it started right up. He followed me to the Chrysler service department where my vehicle has remained since they tell me they can’t duplicate it nor can they find a code that I will have to wait for it to happen again and hopefully a code will pop up that they can fix. Spoke to Chrysler corporatio customer service and then called the dealership. They told her the same thing they couldn’t duplicate nothing they can do. She had no options for me other than to ask them to keep having them drive it until they come up with something , customer service did look it up and states that there is a probable transmission electrical wire issue that caused that to happen. I have requested a full transmission scan as recommended bycomputer forum , but so far no response. I have 2 twelve month old babies and a disabled son that are with me in the vehicle.

What component or system failed or malfunctioned, and is it available for inspection upon request? The alternator snap off while driving on the highway. The snap was clean all bolts are still in the engine block. While driving all kinds of dashboard lights and overheating indicators turned on. How was your safety or the safety of others put at risk? This happens with warning or actions prior to the alternator falling out of the while driving. This put me at-risk of crash and endangering anyone on board, leaving me and family stranded on yhe highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Similar post online with same issues found. Dealer want 80% of the car value to repair and wont help. They recommend changing a cylinder head. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Chryslerbdealer ship inspected. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No signs or symptoms. After the alternator drop off, many issues arise. None prior.

The manufacturer's mandatory 73B Safety Recall update (Vehicle Fires) creates a critical software-induced communication failure on the central vehicle network. Following the 73B flash, the vehicle developed an Active SGW U0001-00 CAN C Bus network fault, which permanently blocks data transmission and triggers an HCP U0412 hybrid battery fault. This network crash disables the hybrid propulsion systems, creating an unpredictable and hazardous driving condition. The manufacturer (Stellantis) and its authorized dealer (Seattle Jeep) are refusing to remedy this safety recall side effect under the vehicle's Hybrid Powertrain Warranty, instead forcing consumers to pay out-of-pocket diagnostic fees ($284.67) and multi-module software update fees ($812.50) to correct a defect injected by the recall software itself. This directly compromises vehicle safety and violates federal recall remedy mandates.

Chrysler performed the 73B recall and n my van in August of 2025. Ever since performing this recall the van has a continuous stream of check engine lights and error codes. The van has been at the dealership at least 6 times for well over 100 days. The check engine lights and error codes always return. The hybrid battery recently had a failure code, and was replaced. I didn't even make it home before I got a check engine light and error codes. The dealership cleared the check engine light and sent me on my way. The codes returned and the van is back at the dealership. The codes I have been getting are : Service Hybrid System, Parking Brake Temporarily Unavailable, Service Electronic Throttle Control, Service Shifter( I was not able to drive as it wouldn't go into gear), Service Electronic Stability Control, Blind Spot Alert, and Service Airbag System. On the longest service visit (over 80 days), Chrysler ended up just telling the dealership to erase the stored codes and return the van to me. They test drive it 50 miles. The error codes returned. They currently have the van again for the same reason.

Apr 2, 2026

While traveling 350 miles from my home with my family of five, the vehicle experienced a sudden 'Loss of Motive Power' event. The dashboard displayed the message: 'Stop Safely - Vehicle Will Shut Off Soon.' I lost the ability to accelerate and had to navigate to the shoulder in high-speed traffic. The vehicle is currently inoperable and the 12V battery has since died because the Power Inverter Module (PIM) has stopped maintaining system voltage. This vehicle had Recall 03A (NHTSA 23V-010) performed on July 7, 2023, and the more recent Recall Y40 update performed on March 11, 2026. Despite having the 'latest software remedy' installed less than 30 days ago, the vehicle suffered the exact safety failure the recalls were meant to address. This proves that the software-only remedy is insufficient to prevent the hardware failure (internal transmission wiring short). A formal Vehicle Scan Report performed at Lake Norman Chrysler (Dealer 60945) on 3/30/26 explicitly shows 'Distance Travelled with Light ON: 146 miles' (Page 14), documenting a sustained failure of the motive power system. Furthermore, the dealer’s own certified technician (J. Olmstead) provided a written Action Plan (Page 9) recommending a full Transmission and Power Inverter Module (PIM) replacement. Despite the documented 146-mile failure history and the technician's recommendation for hardware replacement under the XE1 Warranty Extension, the dealership service management is refusing to perform the repair, claiming they cannot 'replicate' the code as an active fault. I am currently stranded out-of-state with an unsafe vehicle that Chrysler is refusing to repair under the established safety warranty.
