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.

The vehicle presents almost all warning lights then acts very radically . The engine will stall, won’t go in gear . It will happen while vehicle is in motion. Super dangerous. I’ve had it to the dealer 3 times . They can’t seem to find a fix

Intermittently my van will lose power, all dash lights will pop up, active parksense unavailable, service required , blind spot alert temporarily unavailable , service shifter, fcw unavailable service required, service electronic stability control will pop up on the dash and in the message center. Code p0420 has popped up on a reader. Several trips to the dealership purchased at, and they cannot figure out the issues. I have 2 kids, this is a major safety concern. I had it shutdown on a highway 3 weeks ago with my 9 month old in the van. Recall list says everything was repaired, but it seems there needs to be more recalls. These vans are not safe. Recall them all. Chrysler is going to end up with a lawsuit. I think this is a major defect on the electrical and computer systems. When driving the van it will show I'm doing 70 but really 35mph. The van will rough idle. Again these are all intermittent issues that happen all at once. It seems like the van will reset itself once it's sat overnight. We just bought the van in May 2024 and this started a few weeks later. Very frustrating. The dealership won't buy it back, they can't figure out what the issue is. I

I purchased my 2017 in 2023. Within a few months, problems began. When we brought the van back to the Chrysler dealer to have it checked with their OBD2 code reader, multiple codes pulled up… First thing “needing” to be replaced was the hood sensor because the display said the hood was open (even though I was simply stopped at a red light). The auto start/stop light was also coming on and staying on. The dealer said that would go away after replacing the sensor. That repair was done (I believe) in April of 2024 at the Chrysler dealer (and the auto start/stop light came back on a week later, both batteries testing fine independently of one another). Next thing “needing” to be replaced was the accelerator pedal module because my van would start shaking, not accelerate, and go into (what I now know is) limp mode with all warning lights displaying on almost every right hand turn. This absolutely puts my safety and the safety of my four children at risk when it suddenly decides to not accelerate!! That repair was done in June 2024 at the Chrysler dealer. Next thing to happen is the check engine light illuminating. We checked the coolant and it was almost empty! This should NOT be happening! We filled with coolant, but have to do this every few days now. The check engine light has come back on and is still producing many codes, the worst of which is p0303. This code has pulled up every single time we’ve had the van scanned at the dealer. The dealer has had my vehicle on MULTIPLE occasions for MULTIPLE days each time and NEVER ONCE told me the severity of this problem. Their words: We just go down the list, starting at the top. P0303 was not at the top, and now I have to pay the price for their incompetency! My van would not start and had to be towed to the dealer yesterday, 7.17.2024. I’m waiting to hear from them, but I can guarantee this is a head gasket/engine failure issue. Who can afford to just replace an engine?! This is infuriating and beyond frustrating!!

All the warning lights on dashboard light up engine losses power then stop, after setting for two hours the engine restarts, the engine light is only light on. Drive for one or two days light goes off like nothings wrong. Then two or three day’s latter it will do it again. This has been going on for about five months and dealer can not fix it.

I was driving my van and the dash board turns on and off several times. It starts to light all lights while I'm driving. It was a scary situation while im driving my vans brakes while I'm in the freeway. This has happened several times. I also had my vehicle not turn on at all It stays locked and the dash boards says come error code. My vehicle jerks randomly and feels its gonna shut off. Had to tow the car to the dealer, no problem found. On another occasion my transmission was defective and it was changed. . It's has been taken to the dealer several times and I continue to have electrical issues and mechanical issues. I contacted the manufacturer and asked to do a buy back. The company refused and I explained all the issues that I have on my van and no resolution was made.

While driving home from a local store, all the dashboard lights came on and warning signals were heard. Our local repair shop diagnosed a blown headgasket. We are the original owners, 82,000 miles on the vehicle, this complaint is similar to complaints listed for this vehicle on the NTSB website.

I tried to start my Chrysler Pacifica in the morning. The car would not start, and all of the vehicle's dashboard warning lights came on at different times when i pressed the On/Off ignition button. There was no clear, or coherent error message being displayed about what was wrong with the vehicle. Every warning light came on and off. The vehicle's computer module appeared to have malfunctioned. I was finally able to start the car, and brought it to the dealer for checking. The dealer informed me it was simply a low battery problem, but could not explain to me why all of the warning lights on the dashboard and console came on and off. Nothing in the owner's manual explained this sort of issue. I feel very unsafe with this vehicle, as the computer can display warning messages randomly, and disable the vehicle.

This is the second complaint I have filed in 24 hours. I believe I am having a known problem/recall in my vehicle: engine stall due to software issue an engine stall can increase the risk of a crash. The federal safety agency campaign number: 18v049000 I drove about 3 miles. Parked my vehicle and pushed the button to open the sliding back door. When I pushed the button the entire vehicle turned off including the engine and all the lights. Nothing on the dash remained lit. I tried to restart it and nothing happened. No sounds, click or lights appeared. I opened my door and waited about a minute then the interior lights turned on. The sliding back door had to be manually pulled shut at this point. I tried to start the vehicle again and nothing happened. I tried again and it hesitated, then started. I was able to drive about 10 miles to work after that.
