Chrysler Pacifica Electrical problems by year

unable to provide propulsion despite the high-voltage battery having sufficient charge. The problem was not resolved simply by replacing the 12V battery. I brought the vehicle to an Chrysler dealership, where technicians performed an HCP/AHCP (Hybrid Control Processor/Auxiliary Hybrid Control Processor) software update associated with a Chrysler Technical Service Bulletin. I was charged $80 for this update because the vehicle was outside its warranty period and the repair was not classified as a recall. I am concerned that a fault involving the hybrid control system and its software can repeatedly disable the vehicle without adequate warning, leaving the driver stranded and unable to operate the vehicle. Because the issue involves critical hybrid control modules and communication with the high-voltage battery managem

idling as well as the acceleration happened today taking my kids to school. This vehicle should be included on the CDJR XD1 recall. This is also showing in my car overview online, but does not pull up when I called the dealership.

know that it falls under the warranty and they ordered a battery should arrive Dec 15 2026 at the earliest. Called the dealership to verify. They said yes its ordered. 2 days later Stellantis called us and said they canceled the order and it will not be covered under the warranty recall because of our van is over the milage for the recall. She told us to take it to another dealership to see what they say. That would be the 3rd time we done that and this is what they keep telling us. Our van is at the dealership off road because its a fire hazard and can not be driven and they will not honor the recall 52d, Id-25-13 for unlimited miles. Were stuck with no recall getting taking care of. The only option we have is to contact our lawyer and he will be handling this moving forward. Hopefully Stellantis and Chrysler will be 100% held accountable for there actions. I really dont understand how some people can sleep at night knowing they put people at such a high risk of dieing from their vehicle catching fire and expecting people to accept that as its ok. Big safety issue!!!

primary vehicle. Stellantis has finally agreed to order a new hybrid battery and cover our vehicle under the recall 52 and have the dealership mechanic install it 100% free. That was Monday. We have tried to reach out to our star case person Mariah, which she had a lady named Monica call us and we were not able to speak to her, she left a voice mail saying only on the message the part has been ordered? We reached out to the dealership mechanic and he has been more than helpful by letting us know the battery was ordered which he had to look it up when we called because Stellantis didnt not reach out to Auto Nation about our van being approved for the battery recall 52d replacement. Mariah told us last week that when we get approved for the battery that we would need to call her for them to get us a rental. We have been calling leaving messages and no response. Its now week 3 without a vehicle and we have children that have to go to school and the adults have to go to work. But have to ask other people to give us a ride and somtimes are not able to find a ride. When clearly the recall paper states that a loaner vehicle will be provided 100% and we will be takin care of. Please help with them honoring this recall all the way through until it is completed. This has become an inconvenience for our family of 8, because of their mistakes. Were asking you to look into this matter to help us and other people that are dealing with the same recall 52d on their pasific

parasitic draw or a failing alternator/voltage regulator that is frying the shifter electronics. If this vehicle suffers a thermal event or complete powertrain failure on the highway after I was sent away with an unresolved shifting issue, the paper trail shows a clear failure to repair a pre-existing safety hazard reported under warranty."

side street onto a major road. This has started to happen everyday and is posing a safety issue for my two young children, family, and other motorists. This electrical issue is a well known problem of this model and multiple calls to the manufacturer and the dealership leaves me in the middle where neither want to provide a path for assistance as the dealership explains my issue as a manufacturer problem. In the past 3 weeks the electrical issue has impacted the vehicles ability to consistently start, sometimes the engine won't turn over and I have to jump the vehicle on an increasing basis. The start-stop system has created further electrical problems where the start-stop dash signal is on constantly, the dashboard lights up sporadically, and today the vehicle would not unlock by using the key fobs and with no physical key I am not able to access the vehicle.

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.

frame. The driver's side door center roller is now showing identical cracking plastic, binding, and imminent failure. This presents an extreme risk of severe crush injuries or trapping passengers. 2. UCONNECT TOUCH SCREEN (ELECTRICAL & VISIBILITY DEFECT): The factory 8.4-inch Uconnect infotainment touch screen has suffered an internal hardware failure that causes the screen to flash and strobe violently and continuously, even during system reboots. This flashing creates an intense driver distraction and cabin blinding hazard during night driving, severely compromising road visibility. Furthermore, the failure completely disables the backup safety camera and the ability to operate vehicle defrost and climate safety controls.

disabling Electronic Stability Control, Forward Collision Warning, and Blind Spot Alerts. Most critically, the loss of network data causes the vehicle to enter "limp mode," locking the transmission in its current gear and refusing to upshift or downshift, creating a severe crash hazard in active traffic. The root cause is a physical hardware defect in the CAN-C Star Connector junction block (Part No. 68321746AA) located behind the passenger-side glovebox. The pin receptacles inside this distribution block degrade and lose tension, allowing data wires to vibrate loose. Striking the passenger-side dashboard physically reseats the pins, instantly restoring network communication, shifter lights, and transmission function. Dealerships are misdiagnosing this defect by following factory diagnostic trees that mandate replacing the functional Electronic Shifter Module (an ineffective $1,400 repair) instead of addressing the faulty Star Connector. My vehicle has been at the Chrysler dealership since initial diagnosis with no resolution, as the dealer refuses to repair the known wiring defect without first replacing the functional shifter. The sudden loss of transmission control and active safety systems due to this faulty communication block is an extreme safety hazard. Chrysler must issue a mandatory recall to replace these degraded Star Connectors.

propulsion warnings, and leaves the vehicle unable to clear or defrost the windshield in freezing temperatures. A sudden loss of propulsion power in traffic or loss of windshield visibility during cold weather presents severe safety hazards. The manufacturer approved the traction battery pack under warranty but denied statutory coverage for the concurrently failed high-voltage coolant heater, leaving the vehicle disassembled and inoperable.

52d but said its not covered under the recall, and we will have to pay out of pocket. We have been back and forth for over 3 to 4 months because Chrysler, Stellantis, & Mopar keeps denying the replacement of the hybrid battery because they say it passed after the check for the recall, our vin does not match for the recall, our van is over the warranty miles. The last call they gave us a new case # which this is our 4th one and told us to go take it back to the dealership and have them run a diagnosis again to see what it says. We did that and the same code comes back. The dealership opened a STAR case and told us to call Chrysler recall division. We did, she gave us a new case number and told us that a case manager will call us. In the mean time the dealership is waiting and has our van because its a fire recall and hoping that all of the above companies that are responsible for this recall make this right. Please help with this serious matter. Thank you

replacement of the high voltage battery pack, the chiller, the inter-loop heat exchanger, the battery cooling pump, and multiple replacements of the high temp 3-way cabin valve. I eventually traced the apparent cause to the high temp 3-way cabin valve routing engine coolant through the inter-loop heat exchanger at all times, causing the high voltage battery pack to overheat. If the vehicle is left sitting with the engine idling, the vehicle will shut down after less than two from cold. I installed a hose to bypass the heat exchanger in order to address the problem. The repair successfully kept the battery coolant temperature from rising, however, the vehicle still overheats and shuts down. I believe that this model of suffers from multiple design defects in the cooling system making it far more likely than other vehicles to experience a complete loss of motive power.
