Chrysler Pacifica warning lights comes on

Filed Oct 13, 2026 · Electrical · FL

I am reporting repeated electrical failures affecting my 2019 Chrysler Pacifica Touring, including recurring auxiliary battery failures, stop/start warnings, dashboard malfunctions and electronic shifter faults. Despite multiple dealership repairs, the problem continues. August 22, 2023: Auxiliary stop/start battery replaced under Mopar warranty at Jim Shorkey Chrysler, as documented in subsequent service records. August 26–28, 2024: Following another stop/start warning, Ferman Chrysler tested both batteries and found both failed load testing. The main battery was replaced and auxiliary battery warranty work was documented. September 8–9, 2025: Stop/start warning followed by electronic shifter malfunction. Ferman Chrysler confirmed the auxiliary battery had failed and replaced it under warranty. July 7, 2026: Jim Shorkey Chrysler documented previous starting problems and reported battery health at 78%. October 13, 2026: On starting the vehicle, the instrument cluster flickered repeatedly, and multiple warning lights appeared. A Service Shifter warning followed, and the rotary gear selector indicator lights stopped illuminating. Gear selection remained functional, and the lights subsequently returned. Diagnostic codes included P00FD (Battery B state of charge), U145D-00 and U0402-00 (transmission control communication), U0432, U0418, C006A-54 and C2222-68, indicating faults involving multiple electronic systems. My concern is that repeated battery failures may be symptoms of an unresolved electrical defect affecting the electronic shifter, instrument cluster and communications between safety-critical control modules. This raises concerns about potential loss of gear selection or reliable vehicle information. The September 2025 dealership records document a similar combination of stop/start and shifter faults, demonstrating that this is a recurring problem. I request that the federal safety agency investigate this potential safety defect. I have retained dealership invoices.

My 2019 Chrysler Pacifica experienced repeated electrical/network communication failures. The first sign was erratic dashboard behavior and a check-engine light in our resort parking lot. We drove to Pep Boys, where it was evaluated and we were told it was okay to drive. We then drove to Chick-fil-A (.4 miles from Pep Boys). While stopped in the drive-thru in Drive with my foot on the brake, the vehicle began dinging, the engine revved, and multiple warning lights/messages appeared, including the check-engine light, red electronic throttle control warning, “Blind Spot Alert Temporarily Unavailable,” “Service Trans Stop Safely Shut Off Engine to Engage Park,” and “Stop/Start Not Ready.” After shutting it off, it would not reliably restart, and when it did, I could not shift it to move. The vehicle returned to Pep Boys, where DTCs U0001 (CAN C Bus) and U0401 (Implausible Data Received From ECM/PCM) were documented. It then went to a Chrysler dealership in Florida. They evaluated it and told us it checked out and was okay to drive. After leaving that dealership, the problem returned while my family and I were traveling at highway speed. The vehicle malfunctioned and began losing acceleration. I exited the highway. When I stopped at a stop sign, the vehicle died. It restarted but again would not shift. Eventually we were able to reach a nearby gas station. The problem continued intermittently as we tried to get home. Because we could not predict when it would happen again, we determined it was unsafe and had it towed. A Chrysler dealership in Georgia then documented numerous loss-of-communication codes and performed a PCM software update. The vehicle passed testing and was released, but the problem returned again after we returned to Ohio. The vehicle was ultimately towed to a Chrysler dealership in Ohio. The communication faults became active during diagnosis, and the dealer replaced both CAN-C and CAN-I splice-block connectors. The problem has not recurred since.

• 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.

I am a full-time power wheelchair user with Multiple Sclerosis and rely on this 2024 Chrysler Pacifica wheelchair-accessible van as my primary means of transportation. Since purchase, the vehicle has repeatedly experienced dangerous loss-of-power events while being driven. Immediately before the failure occurs, warning beeps sound and multiple warning lights illuminate, including Check Engine, ETC, Park Brake, FCW, ESC, and MIL. After these warnings appear, the vehicle loses acceleration and enters a reduced-power/limp-mode condition. Pressing the accelerator does not result in normal acceleration, creating a serious safety hazard in traffic. Most recently, on June 4, 2026, this occurred approximately six times during a single trip. During one incident, the warning lights illuminated, the vehicle lost acceleration, and we were forced to pull over with emergency flashers activated in a dangerous location. A police officer came upon us, stopped to assist, and advised that the location was extremely dangerous. Because I use a power wheelchair, I cannot safely transfer into a standard vehicle, taxi, rideshare, or other transportation. We explained to the officer that if the van were to be towed, I would effectively be stranded because there was no practical way to transport me in my power wheelchair. The condition later cleared and we were able to continue. The vehicle has been inspected multiple times by Chrysler service departments and DriveMaster, the local mobility provider working with Freedom Motors. The problem has been reported repeatedly but is intermittent and has not been reproduced during inspections. Despite multiple repair attempts, the problem persists. The vehicle is available for inspection. These recurring loss-of-power events create a serious safety risk for myself, my family, and other motorists.

Four separate incidents but related incidents. Primary concern: vehicle turns off and puts itself in park without notice and cannot be restarted. Two incidents were in traffic at a stop light, and the vehicle could not be started for 12-15 minutes. Two times it occurred while the vehicle had been parked for a short period of time but could not be restarted. March 4, 2026 driver was stopped at a light, after about 20 seconds, driver received a dash message “Press brake and push button to start” indicating the vehicle was off, and the vehicle was in park. Driver depressed the brake and the vehicle started. March 7, 2026 driver pulled into a store and when they excited the vehicle, they notice their carplay was still attached to their phone/music. Driver disconnected their phone but notice a dash message “auxiliary connected.” Driver attempted to start the vehicle, but it would not start, however all of the lights, carplay, messages were cycling as if the vehicle was on. When driver attempted to start the vehicle there was no give to the brake and the vehicle would not start. Driver was able to start the vehicle 15 minutes later. March 27, 2026: Driver was stopped at a light and the vehicle turned off and put itself in park. Driver had to contact police t0 block traffic to prevent vehicle from being hit. Vehicle started after 15 minutes. Driver immediately took the vehicle to the dealership. April 2, 2026: Dealership service technician called and said they could not recreate the problem, that all codes were checking out, however they did see a intermittent short in the crank sensor and it was replaced. April 3, Owner pick up the vehicle at 5:30, drove five miles away. Put the car in park to get fuel and the vehicle would not start. Again – “press brake and push button to start” was indicated on the dash but the vehicle could not be started. There is no warning to when this happens. No sputtering, engine noise, just unusual turns off and goes into park.

While I was driving the car started beeping and all dashboard lights started flickering. Transmission started stuttering and engine rpm fluctuating wildly. Fortunately I was in my neighborhood and was only going about 15 mph and was able to pull to a stop. The issue is with a faulty star bus connection near the glove box. After watching a you tube on the same issue, I learned to hit the area near the glove box to reset the star bus connection. This has happened before but usually on startup. Dealer not able to repair after $1600 charge. This is the first time it happened while in motion. Again. Seems to be a common enough issue that there are several you tube videos with thousands of views.

The CAN BUS connector (found in the glove box area) fails periodically and without warning. It affects everything on the vehicle; it stops the car from shifting, car won't start up, windows stop working, all of the warning lights turn on, etc. The issue seems to be a manufacturing defect; the soldering cracks after a while, so the low voltage applications malfunction. Many people have noticed the problem, but the dealerships refuse to do a recall or address the issue properly. The vehicle has been in and out of the dealership probably 10 times in the last 7 months or so. The vehicle is available for inspection upon request. This problem is unsafe because it can occur while driving on a freeway which can cause an accident. Every warning light comes on when the malfunction happens.

My 2017 Chrysler Pacifica Touring-L has suffered repeated and dangerous electrical failures since purchase. Shortly after buying it from AutoNation Chrysler Dodge Jeep RAM in Valencia, CA, I had to return it twice for electrical repairs that kept it in service several weeks under warranty. About two years later, while still under extended warranty, the engine underwent a complete rebuild for multiple-cylinder misfire codes that were likely caused by intermittent CAN-bus voltage loss rather than a mechanical defect. Over the past nine months, the vehicle has again developed severe electrical faults while driving: sudden loss of power steering assist, all dashboard lights illuminating, windshield wipers activating spontaneously, and the engine failing to shut off using the Start/Stop button. The vehicle has also stalled without warning while driving in traffic or idling at red lights, restarting only after 5–10 minutes and blocking traffic lanes, placing me and surrounding drivers at significant risk. Two major repairs in the last two weeks failed to resolve the defects: (1) repair of the CAN-bus system after the vehicle would not start and acted erratically while driving, and a week later (2) replacement of the brake-booster vacuum pump, which was shorted internally and caused CAN-bus shutdown, complete steering loss, sudden braking, and no engine power. The vehicle is currently at Dependable Chrysler Dodge Jeep Ram, Canoga Park, CA, awaiting further diagnosis despite repeated repair attempts. These symptoms match Chrysler TSBs 08-007-17 and 08-033-21 concerning Body Control Module water intrusion and communication faults. This ongoing electrical defect has caused steering loss, random stalling, ignition failure, and unpredictable vehicle behavior—issues widely reported by Pacifica owners. It poses a serious safety hazard and warrants immediate investigation and recall.
