2017 Chrysler Pacifica electrical problems

Filed Nov 2, 2026 · Body, Electrical · GA

The vehicle has suffered multiple severe safety hazards involving the power sliding doors and the primary dashboard infotainment screen. 1. POWER SLIDING DOORS (BODY DEFECT): Both the left (driver) and right (passenger) power sliding doors have experienced a critical structural hardware failure of the center roller hinge assemblies. The passenger-side center roller wheels completely shattered during operation, causing the entire heavy sliding door to catastrophically detach and fall completely off the vehicle 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.

safety complaint regarding a severe CAN bus communication failure in the 2017 Chrysler Pacifica (gas model, base trim, no Engine Stop-Start) resulting in a sudden loss of transmission control while driving. The defect manifests as an intermittent loss of communication between the Electronic Shifter Module (ESM) and the Transmission Control Module (TCM). Without warning, the rotary shifter (PRNDL) indicator lights go dark and a "Service Shifter" message appears. This triggers a cascade of safety system failures, 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.

While driving and accelerating in the Walmart parking lot, the van immediately locked up, slammed myself and my kids forward, and was locked where it would not engage any gear other than park.

Made a right hand turn onto residential street and van immediately parked itself mid turn which would have resulted in accident had someone been behind me. Vehicle was able to restart and reach destination but now P1B14 code is thrown. This is unacceptable for a car to shift into park while in motion. Code is related to known earlier issue with van that was supposedly repaired. 2 weeks ago while inching into a parking spot the van seemed to have lost power for a split second but resumed as I finished parking. I feel very unsafe in vehicle.

This occurred on [XXX]. I was driving with two passengers heading west bound on [XXX] in Ohio and starting to go off an exit ramp. The passenger side power window went down without anyone pressing a button. I pulled up on the driver-controlled passenger window switch to correct the window, and it went up. But, either immediately upon going up or shortly after (I don't remember), the van experienced a series of electrical faults. The CEL came on, I start hearing warning chimes, the infotainment screen rebooted. I heard a clicking noise from under the hood, which I later learned was the parking pawl trying to engage. Dash screen said something about "speed too high to shift to park." Momentarily the wheel jerked hard - I think I lost power steering (if the car fully shut off I think that's what happened). I gained control and directed the car to the side of the road. I don't know what state the car was in at this point - either fully off or electrically on but no engine power. In any case, I shifted to park, pressed the on/off button and the car fully shut down. After a couple of minutes I attempted to start the car again, and it started right up with no issues. The CEL was lit, but the car drove fine. When I got to my destination about 20 miles away, I checked the battery terminals. I found that the negative terminal could be turned about a quarter turn if I used some force, but it was not what I would consider 'loose'. I still tightened the connection as much as I could, to the point that the connection was now immovable. The CEL cleared after a few cycles of turning the car on and off. A scan later showed that code P1B14 was stored. I called multiple Chrysler dealerships and each told me that they could not diagnose the problem unless it was actively acting up. The car has not malfunctioned since the incident four days ago. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? Intermittent loss of EPS assist during gradual turns, especially when the steering wheel is near the 11 o’clock or 1 o’clock position. How was your safety or the safety of others put at risk? Not being able to control the steering wheel puts my safety and others at risk. No, the problem has not been reproduced or confirmed by a dealer or independent service center. No, the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. No, there weren't any warning lamps, messages or other symptoms of the problem prior to the failure, and it occurs when the steering wheel is at 11 or 1 o'clock at speed.

Steering sticks during a gradual turn. It will catch up but then causes over correction. This has happened multiple times and based on my research, this is a model-wide problem. See campaign PE25009 for more details.

Put the car in park car instantly cut off didn't come on. It was having electronic issues said service ABS system, service steering control and I had to get it towed. Had the whole car diagnosed brought a new battery the another was fried due to corrosion.(the issue was the wiring harness) One month later put the car in park car did not come back on stated ABS system and steering control needed to be serviced once again battery fried. Towed again once again got a new battery. Had a diagnostics.and it was the was wiring harness again. 3rd time in a year when the car shuts down, it’s impossible to use anything in the car. If the windows were rolled down, you can’t roll the windows up. If the door was left open, you can’t close the door. You can’t even shift the car to neutral even with the manual function, you can’t shift the car to neutral. Everything is locked.

On XXX, my 2017 Chrysler Pacifica suffered a catastrophic malfunction on [XXX], only 3.4 miles after I picked it up from Mall of Georgia Chrysler. The dealership had kept it for over two weeks to diagnose an intermittent “Service Shifter” warning and communication fault codes. While driving in traffic, the gear indicator unexpectedly cycled among Drive, Neutral, and Park. The vehicle stalled, moved unpredictably, displayed flashing warnings, and sounded chimes. I could no longer reliably control its propulsion or determine whether it would remain in gear. This nearly caused a multi-vehicle collision before the vehicle became disabled and had to be towed. This was not merely a “Service Shifter” warning. The safety event involved an unexpected Neutral condition, loss of reliable propulsion and gear control, stalling, and a simultaneous electrical malfunction. Christian Brothers Automotive had replaced both batteries and the service shifter module. The warning continued, with stored codes U0103, U1465, U1467, and U11E3. Mall of Georgia Chrysler identified the same codes but again replaced the main battery and service shifter module. The vehicle malfunctioned after those repairs, was returned for further diagnosis, and then suffered this roadway failure immediately after its next release. Despite repeated repair attempts, no root cause has been documented. The dealership proposed replacing another transmission-related module and electrical component but could not guarantee the repair. I am concerned that parts are being replaced through trial and error while the safety defect remains unresolved. Chrysler TSB 21-027-17 Rev. A addresses transmission shift and drivability concerns in certain 2017 Pacificas, including code U0103. I ask the federal safety agency to investigate this as a loss-of-propulsion, unintended-Neutral, transmission-control, and electrical-communication safety defect—not simply a dashboard warning. The vehicle remains unsafe to operate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.
