2018 CHRYSLER PACIFICA Electrical System Problems

The contact owns a 2018 Chrysler Pacifica. The contact stated the Auto STOP/START light and head gasket light remained illuminated. While starting the vehicle, the vehicle was vibrating abnormally. The vehicle was taken to the dealer who diagnosed a leak in the head gasket. While inspecting the vehicle, the dealer became aware of a hole in the engine, and that the engine and head gasket needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case number. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 92,000.

I keep getting a check engine light with my Pacifica hybrid. The scanner says P1B11, soft code is P0506, Hybrid battery or wiring harness. The codes erase after driving for a long while, however, I notice that I’m not able to maintain a full hybrid battery charge for longer than a few miles. After about 5 miles of driving, I’m a 80% of battery life left. MPG averages about 30+/- something’s not right. It’s happened twice now, both times with excessive outside temperatures. 1st time while idling, 2nd time while stopped for fueling.

On 4 separate occasions the vehicle while in motion will flash an alert that states “vehicle shutting down, stop safely” and the van will proceed to completely shut down- all electrical components do not work, including the sliding doors. After 30-45 minutes, the can will start back up without issue. Has been evaluated by a Chrysler dealership mechanic, as well as 2 private mechanics. They have been unable to replicate the issue. The main and auxillary batteries have been replaced twice each. Each incident we were able to pull over safely and there have not been any injuries or crashes, but we are concerned if it happens and we can’t pull over, we could easily crash.

In March of this year (2024), while driving down the road at 45 mph, my Pacifica's dashboard suddenly lit up and flashed all kinds of warnings including ABS off, the check engine light, the parking brake, the service electronic throttle control, electronic stability control off, collision off, warning parking brake, and other lights that I'm not sure what they mean. It seemed like every warning light in the panel lit up. The van slowed down and wouldn't let me accelerate and it felt like the power steering wasn't active. I pulled into a parking lot and shut the engine off. After restarting, the check engine light was lit, but the van let me proceed. I took it to my auto shop that said the codes were all electronic/ software related and I had to take it to a dealership. The dealership said they couldn't find anything wrong and that the...

Back in January While driving and stopping at a red light the warning light appeared that the stop/start function was unavailable. The warning "electronic service" appeared and went away. While stopped at a red light the vehicle turned off with no other warning. This put me at serious risk with my children in the car for an accident. After a minute I was able to turn my car back on get hhome. I had my vehicle serviced and had a new main battery put in. Now in June the same warning came on again. I have to pay hundreds of dollars just to get a diagnostic report. This is the second time in less than 6 months. This is putting my safety and the safety of my family at risk.

The contact owns a 2018 Chrysler Pacifica. The contact stated while driving at an undisclosed speed, the contact noticed a failure with the START/STOP system. The contact stated that on several occasions the vehicle lost motive power and stalled with the START/STOP engine warning light illuminated. The dealer was contacted; however, the vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 80,000.

Head gasket is blown with not that many miles, it's blowing fuses on a daily bases, start stop function won't work. Coolant leaks. Coils damaged, and lastly ac unit won't close properly and keeps making noise.

While driving a message came across the dash to "service charging system" and then a second message appeared that said "speeds limited" and the vehicle slowed to 44mph entirely out of my control.

There is a loud clicking and popping noise from the front drivers side suspension when turning or going over bumpy ground. The car also pulls to one side unexpectedly when going around corners Sometimes while driving the car will shut down and restart as if rebooting a computer.

My Vehicle suddenly stops while the car is in motion, it shuts completely off. I had an instance where my car shut off coming off the freeway off-ramp. This has happened on numerous occasions and we have been trying to call the dealership to see if there is any recall. We are never given a straight answer and we feel unsafe to drive our vehicle

The van auto shutoff during a stop in an intersection. The van did not turn back on when the pressure was released from the pedal. The engine was off and I was in the middle of the intersection. The gear shifter knob was unable to move to a different gear. After multiple attempts to restart the car were unsuccessful, the car finally restarted after cycling through the att, run, start menus without the brake being depressed and then pressing the break and pushing the start button. This vehicle has had the recall work performed related to this issue and the repair is insufficient. The stall is intermittent and difficult to repeat.

The vehicle display reads "Service Charging System" and switches into limp mode where the vehicle is prevented from driving faster than 15 mph. After leaving the van sit for a time, it drives ok. I took the van to a Chrysler dealership twice after this happened, and the dealership could not resolve the issue. After the second time this happened, the dealership contacted an engineer at Chrysler to try and resolve the problem, but they could not. Chrysler says the problem stems from the charger that is being used, but the error/limp mode occurs not after using a charger. I am concerned that the vehicle will switch over to limp mode at any time presenting a safety risk.

The #5 cylinder keeps having a misfire sometimes causing failure of the vehicle to get up and move when needed in an emergency Situation this being a family van make even putting children in danger at times. After inspection by myself a Mechanic that even taught College Automotive repair, I have also taught Jet engine repair I find this concerning. Is what is happening is the head gasket is leaking coolant into the #5 Cylinder and we all know water will not admit a spark. Rust can be seen on the Valves and top of Piston cylinder upon inspection. This is a well know issue across the United States and Chrysler Dealers and manufacturers, their mechanics, parts and service departments also know this. This is poor workmanship inferior parts. But the most concerning is not being able to get a response out of the vehicle to get out of the...

The check engine light came on and the vehicle experienced a slight loss of power. Later the Start/Stop indicator light cam on with a message saying it has malfunctioned. Upon driving the van continues to have issues going up hills and accelerating from a stopped position. The check engine light remains steady without blinking.

Initial Symptoms: Auto-start/stop failed/tripped, plus excessive white exhaust smoke continuously exits (will not stop). Stopped driving vehicle ~26Nov2023. Problem 1: P0303 Solution 1: Ignition coil and spark plug replacements @ $905.17 (15Dec2023) Not Fixed: Error code is gone but white smoke persists. Problem 2: Chrysler tech found low coolant, traced to EGR cooler. Solution 2: Replaced EGR cooler @ $1,319.00 (05Jan2024) Not Fixed: Excessive white smoke still exits tailpipe and does not stop. Neither solution fixed the root cause. There is also an engine smoke smell in the cabin (we don't smoke). Potential Root Cause: Failed head gasket forcing coolant into the engine then burning out as white exhaust.

oticed that the CEL had come on, and after reading the codes, I found out that there was a cylinder 5 misfire. To fix the issue, I decided to replace all the spark plugs and ignition coils, and after putting everything back together, I erased the codes. However, the following day, the same code appeared again, and I realized that the coolant level in the reservoir was low. I performed a pressure test on the system and ran it to temperature, but there were no coolant leaks. While the car was running, I observed bubbles in the reservoir, and these signs pointed towards a blown head gasket. After checking online for Pacifica common issues, I found out that head gasket failure is one of the main complaints. As a mechanic with 13 years of experience, I know that these symptoms indicate a blown head gasket. Unfortunately, due to this issue,...

After radiator was replaced by the dealership, our car has been experiencing coolant leaks that we have “repaired” twice, however the issue keeps coming back within the week. We are also experiencing stalled engine will driving, where the car just slows down instantly or stops.

The contact owns a 2018 Chrysler Pacifica. The contact stated that the main battery and the auxiliary battery had been replaced on multiple occasions. The dealer had not yet determined the cause of the failure. The contact stated that the frequent battery failures caused the vehicle to stall while driving at various speeds with the battery and check engine warning lights illuminated. In addition, the contact stated that the vehicle was diagnosed with a cylinder #3 misfire. Also, the contact mentioned that the vehicle would jerk forward upon depression of the accelerator pedal without warning. The vehicle was taken to the dealer for a diagnostic test; however, the dealer was unable to determine the cause of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 46,000.

Suddenly our Pacifica would not start and started cycling through over a dozen error messages. We were finally able to get the vehicle to start and took it to the dealership. They confirmed that the star connector needs to be replaced. After looking at many forums, this appears to be a fairly common issue among the early hybrid pacificas, to the point that I felt I should report here, especially given the recalls that have already happened due to the electrical system in the car. We just got the last recall done in August and already we now have a ~$1000 bill to repair the electrical system again. Please have someone look into how many of the pacificas need this particular connector replaced given the prevelance of people with the same issue online.

What component or system failed or malfunctioned, and is it available for inspection upon request? The shifter module fails or malfunctions and it put the vehicle in park. All the electronic controls in the vehicle malfunctions even when the vehicle is driving like the ABS, displays, throttle, ADAS and all other controls How was your safety or the safety of others put at risk? The vehicle suddenly starts throwing the warnings while you are driving - sometimes in the freeways, it also jerks, throttle and other controls and displays goes blank, you are not sure even if the emergency flasher is activated Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and...

We began having major issues with our van in October 2022. There were numerous incidents of loss of power and sudden increase in temperature gage. We kept fluids checked. Kept oil changed on time. We reported this to the dealership multiple times before they agreed to fix under warranty. Even after fixing factory recall (which we were charged for by the dealership) and then replacing batteries, we continued having issues with loss of power and surge in temperature gage. July 8th of 2023 engine light came on and temperature gage shot up, van stalled at the intersection. I had My self and FIVE kids in the car. This was accompanied by a sudden loss of fluids. We had the van taken to another repair shop who then told us the head gasket was blown. This happened just 4 miles after our warranty lapsed. We had to have the entire motor...

Driving through a parking lot when the van said shift to park and completely shut off while moving. Lost power steering and acceleration. Car then would not restart. Husband came and we hooked to his battery and somehow it cranked and we got it home.

Our engine has stalled while driving the vehicle at least four times since July 1. The engine begins to shudder, and the car will not accelerate, and then the engine completely dies. After it happened today, it was not possible to restart the engine or put it in gear. My and my family's safety was put at risk because the vehicle was inoperable. Three times this happened on major interstates with traffic moving at high speeds. I had to move my children and their car seats into another vehicle while traffic passed. We have had the vehicle in for service at least three times, at least twice at Chrysler dealers. The problem has not been reproduced (yet) but this latest time it completely disabled the vehicle so expect they will see more of the problem now. After the engine cuts out, we get an electrical warning light that flashes briefly,...

On the NHTSA says as of January 17,2023 compaints on 2018 Chrysler Pacifica With inspected engine shutdown..

The service electronic stability control warning is populated after the vehicle stalled while driving on the freeway. The vehicle often jerks and stalls when taking off or driving at slow speeds but this is the first time at freeway speeds. This early caused an accident for me and my family.

My car won't start it says that the engine or accessory is on when it isn't. I had this same problem last year during covid so I replaced both the batteries last year. Now it's doing it again. This time how ever the light is flickering on the drivers side. The doors when I first got it and sometimes says still that there not enough power to operate sliding doors.

- The car still has open recall Z11 ( RU PHEV hybrid traction battery fire). - The car had open recall XE1 RU PHEV transmission open. - The car became stranded refusing to put the transmission into gear. - Had to tow the car to the dealership. The dealer stated the traction battery fuse was blown. The dealer could not pinpoint the root cause of the issue, nor did chrysler have parts readily available to fix. The car still shows there's an open short. - The dealer could not complete diagnosis because of the Z11 recall. They stated that the traction battery can not complete self check procedure. - Chrysler is unresponsive in following up on the issue.

On 5/31/22 I took my vehicle for service due @ error. The dealership Mac Hakil I-55 Jackson MS slept my vehicle until 6/2/23 telling me it was my battery charging $813.00. I feel this was a ripped off

@ error message vehicle sometimes stalls at red lights or 4 ways stops. I have to cut off the vehicle to restart.

I HAVE PROBLEM DETACTING COMPUTER FOR STATE INSPECTION IN TEXAS, ITFAILED INSPECTION DUE TO NOT DETACTNG COMPUTER

This vehicle has been towed to the dealership for service for a 5th time! Lights of all systems start flashing as not available. This time I had loss of power driving. I got off a main road, but was not able to put the car into park or engage emergency brake as no systems were available!! I sat with my foot on the break while the “p” for parking flashed and the engine just wanted to rev. I have pictures that tell some of the story. It took 40 minutes for the car to recognize that it was in park (or reset). They’ve already had this car in September of 2022, October 2022 two separate incidents, and then again for an entire month from November-December, with no loaners or funds towards rentals. Last week the car lit up the same way, but this time I was not in my neighborhood,...

The informational screen when turned on get super super hot and has slightly warped the dashboard. I believe There is a connection between Having the informational screen on while driving and the steering wheel sticking. It sticks less when the informational screen is turned off. I worry that if I’m driving with the radio on it will catch the car on fire

Auto on/off was working for a few days (which is not normal). When in the drop off line for school it turned off for that. When I let go of the gas to go, the car shut off completely. I restarted it and it said "service shifter" and the shifter lights did not come on. I did move it to park by counting the clicks of the turns. Drove home from the school. Same day and other days following, the auto on/off is back to not working. Randomly when I start the car it says the "service shifter" message and does not light up the shifter letters. Sometimes if I turn it off and then back on it will not appear. Other times, it does and I have to just go. This is a safety hazard if it shuts off and will not turn back on. This started roughly 1.5/2...

2018 Chrysler Pacifica T, Uconnect infotainment system shuts off and reboots every 2-3 minutes while driving. It is available for inspection upon request. When the Uconnect shuts down driver loses all features connected to the system to include: GPS/Navigation, blue tooth, in-cabin climate controls, and back up camera. This causes the driver to become distracted in order to re-synch phone, dvd player, navigation. Additionally, my wife almost backed over a 6 year old child because the back up camera shut off when backing up from a parking spot. There is an incredible risk of injury/death with this systems failure. The issue has not been reproduced by the manufacturer (FCA), dealer or independent service center. This issue is being addressed by class action lawsuit: Case 2:20-cv-11838-SFC-RSW ECF No. 1 filed 07/07/20 The vehicle was inspected by the state of Maryland. The vehicle is now at the dealership for diagnosis and I...

Service electronic stability

First, it started with the stop/ start not working . We took it to the shop they said we needed a new alternator. Costed us 700$ . Well the problems did not stop . The check engine light did not go off after a few times of driving it (the mechanic (crystler mechanic) said it would after a few times of driving it. Well then it started rumbling when u turned it on . Called and they said bring it back in. Well we planned on doing so but then the van wouldn't start. We had to get it towed . Well they said the fuse had blown . So when they replaced that they noticed white smoke coming out and all the coolant gone . They said it is most likely the cracked engine block which is gonna cost over 12000$ to fix . We already owe money on...

The car starts blowing out white smoke when started. Mechanic thinks it could be a blown gasket or Crack in engine block. The cable fuse blown as well. The vehicle did not start so it was towed to the mechanic.

Coolant leak as well as the other problems that I reported.

Car was on cruise control. While approaching traffic, attempt was made to release cruise control by braking. Brake system was locked, vehicle started accelerating and revving. Brakes would not work, had to swerve to avoid collision. Managed to fidget with the gear knob. Finally managed to gain control of vehicle. I figured I gained control because I must have shifted the gear into Neutral somehow. I had my entire family of SIX in the car. Without having gained control, the vehicle would have accelerated until I crashed it. It accelerated past 80mph before I could gain control

The end of 2021, Began not starting requiring many pushed of the start stop button; stalling when in motion on roads; gas pedal tight not depressing, engine light on and off, side auto doors often wouldn’t work automatically (battery new); was lurching and chugging randomly , over time very frequently. Nov 22’ had start stop battery replaced & fuel pump sensor. still lurched etc..worsened..late 2022 began frequently stalling , not starting, pedal would be stiff, lurched daily, stalled frequently during motion & upon first acceleration..start, try to go..stall out..finally jan 5, 2023, wouldn’t even turn over-just clicked-shop diagnosis said few codes referred to electrical panel issues.. replaced spark plugs, starter, got home, next morning, same thing ~no turnover. problem not solved. another shop, where it sits today-found cracked engine block($12,000 estimate to “attempt” replacing engine). deemed total loss as value of van is less. This has to be a defect...

Reverse camera screen remained on after reversing and during a ~30 minute drive. Stopped vehicle, shutoff engine, opened door to trigger interior electronic shutoff. Restarted vehicle and backup camera still remained during drive until eventually changing to full blue screen with "Camera System Unavailable" message at the top. (photo available) The event occurred during extreme winter weather in Oklahoma 1/30/2023 and is an obvious safety issue. The constant rearview display while driving is very distracting and disorienting. Additionally, the vehicle climate control settings for defog, heat, and other settings are unavailable for determining and adjusting to external environmental conditions, as experienced during the winter weather event leading to full interior fogging and reduced visibility (another mechanical safety issue prevalent to this vehicle series). This issue is found under NHTSA Campaign 19V886000 for 2018-2019 year models however, our VIN is not included. I contacted the original dealer service department, and they...

I am aware of the recall on this vehicle. In addition, I received a phone call and email from Chrysler stating the following: "Hello Mr./Mrs. I have attempted to get ahold of you to schedule your Z11 Recall appointment for your Pacifica PHEV. You should have recently received an important recall notice from FCA detailing the steps needed to repair your vehicle and ensure the safety of you and your passengers. If you would like me to continue to assist you with the appointment, please give me a call at 8009921997. We encourage you to schedule this service appointment as soon as possible. If you prefer to schedule the appointment by yourself, ask for the Z11 point of contact at the dealership, and be mindful that the repair takes 2 days to complete. Please be advised that I have closed your case. Thank you for being a valued Chrysler customer....

Car engine has stalled a dozen times or so. On one occasion it stalled and would not restart, had to tow to a dealer to repair it and it ended up costing $2700. And when it doesn’t stall on the road the engine constantly has weird acceleration dips where it almost stalls. This has been a constant problem for me and I purchased the vehicle used with 39000 miles on it. Which is not much mileage so I was not expecting this many problems.

Power Steering is unavailable Stop/start is unavailable Wasn’t able to avoid an accident this morning from deer. Steering went out.

Dear Sir or Madam, There was a recall on our vehicle for the Battery Cables. It was supposed to fix the Stop/Start on our car. Prior to getting the Recall done, our car didn't restart at a stop light/sign causing us to put it back in park and restart the car. We went to have the Recall done and were told that that would not fix the problem, we needed to buy the second battery. We did - costing us over $200. I can ask for the bill for this if it is needed. I could not find it in my files. A couple of months later it started again at the stop light/signs. We took the vehicle back and they said a code was coming up under the hood and that would be no charge. They called us on 10/4/22 and said we need to purchase a switch -...

The car battery system has failed over 5x when driving. All of a sudden the car battery lights start coming on & stearing shuts down and car stops. The last time it completely shut down. No power to even run hazard lights. No power to lock the car or rollup the windows. It has been 2 weeks and dealership mechanic can not figure out what is wrong.

We were involved in a small fender bender accident, and the car caught on fire. It started with the dashboard, and it spread to the rest of the vehicle. The car ended up burnt to a crisp. Nothing salvageable.

What component or system failed or malfunctioned, and is it available for inspection upon request? The van stalls, the wheels lock up, the transmission shifter becomes unusable, and of the warning light start flashing on the dashboard. Yes, it’s available for inspection upon request. How was your safety or the safety of others put at risk? It stalled in the middle of the road blocking traffic from both ways and was unable to be moved for over half an hour. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, not until the day it stalled on 8/30/2022z

Van started running slightly rough in the mornings if the engine was cold. CEL eventually came on with a P0304 DTC. I replaced the igntion coils and spark plugs since the van was right at 80,000 miles. Seem to run fine for a day after, then issues came back. Took it to the dealership for more in-depth troubleshooting and repair. They failed to do anything after almost two weeks except that now my van wouldn't start. Took the van to a non-dealership affiliated repair shop and they said the starter had failed, but the engine passed the pressure check of the head. Waited almost another two weeks for a new starter, mechanic got it back together, found some coolant coming out of the exhaust manifold and recommended adding leak stop that there might be a small casting issue with the engine. They added leak stop and returned the van to...
