2017 Chrysler Pacifica electrical system problems

“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…”

“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…”

“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.…”

“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.”
