Adaptive Cruise Control Problems of Chrysler Pacifica

This car has had so many issues in the 2 years that I have had it. Blown head gaskets, hard shifting, cruise control getting stuck in a high gear and not shifting. When fixing the head gasket it was apparent that it wasnt the first time being fixed. For such a nice vehicle it has way too many problems for the amount I purchased it for. There needs to be some sort of compensation for this. Upon looking into these issues there are thousands among thousands of people with the same head gasket issues and transmission issues as well.

On two separate long trips (over 4,000 miles total in recent months), the adaptive cruise control system has failed while driving on the freeway. This is the most dangerous situation I have ever experienced while driving. When the failure occurs: all cruise control and lane-assist buttons become unresponsive. Dynamic cruise control remains engaged. When I press the brake, the vehicle slows—but as soon as I release the brake, it begins accelerating again. There is no way to turn the system off. The first time this happened, I attempted for several miles to reset the system while controlling speed using the brake. I exited the freeway. At a traffic light, when I began to release the brake after stopping, the vehicle accelerated unexpectedly and nearly struck the truck in front of me. With the brake fully depressed, I shifted into neutral. The transmission made a loud clunk as the engine began revving. I then shifted into park, which caused another loud clunk. I turned the vehicle off while sitting in a turn lane, waited a moment, and restarted it. The system appeared to reset, and I was able to continue driving. Approximately two weeks later, while returning from California, I tested the cruise control system again during a long drive. After about three hours, the exact same failure occurred. This time, I recorded video of the incident and have documentation of the malfunction. This system is extremely dangerous in its current state. I paid a significant amount for this vehicle and its safety systems. A failure like this could easily result in a serious accident or loss of life. I do not believe I should be responsible for paying for a vehicle or system that is defective and poses a safety risk. I have video but could not upload it. .

During normal driving from office to home car suddenly started stuttering and I was apply break but speeded up and showed engine light on, I was about to hit front car due to additional speed. During that time I saw few quick messages on the dashboard, the one that I can remember was related with acc. That's the dangerous situation. I looked d from obd and found that code was u0412 and reported that code to huntington beach Chrysler service station. Please keep an eye out for some similarities between others reports.

When adaptive cruise control is enabled and I’m at cruising speed, new vehicles entering the lane in front of my vehicle are not being acknowledged leading to my vehicle getting too close and collision becoming likely. This leads to me having to takeover control frequently to prevent accidents. This happens often, not always, but it is becoming more and more frequent. This happens at all speeds from 30 mph to 70mph.

Electrical adaptive, cruise control, forward collision warning, and shifter all malfunctioned. It is available for inspection. There was failure to accelerate at an intersection which almost caused vehicle to be rear ended. The error codes have been pulled and shown by o’reillys auto parts. The vehicle is pending inspection by an independent mechanic. The adaptive cruise control the Ford collision, warning and service shifter warning lamps all appeared shortly before this problem occurred.

When driving van will jerk or bang like slipping in gear, feels like possible being hit from behind, we have tried the adaptive learning reset several times, we had just purchased this less than 2 months ago with about 4800 miles in it. Feels dangerous to drive, especially with kids. We are scared to even try the cruise control. We heard and read online many whey same issues, with warranty and having there vans in dealership on several events, having reset in software upgrades, transmission replacement with only the problem to return. Please fix this, this one of my vehicles that unfortunately I have to drive because it's my only vehicle. This problem happens at lest everytime I'm driving daily, it started maybe a few weeks ago from the time this has been written.

Van was working fine one day and the next, before I even started it, when I pressed the brake pedal to start the van, there was a buzzing noise from the braking system and pedal went almost to the floor. Once I started the vehicle, the noise stopped and the pedal travel returned to normal. However at the same time, the warning light / message for several of the systems came up (abs, traction control, collision detection, parking sensors, etc) along with several messages (parksense unavailable, fcw unavailable service required, service antilock brake system, service electronic stability system). Using an obdii code reader displayed several "communication errors" (start with the letter "u"). I researched it on the internet and it would appear that this is caused by a common failure of the "star connector" ("bus module" to connect various components in the van). I ordered a replacement part (which I haven't received yet) but not completely surprisingly, about 1 week after the issue occurred, today my vehicle was running properly with no more errors. I'm hoping NHTSA forces fca to fix this issue under a recall. I've read of several other owners suffering the same issue and imo, this is a security risk as abs and traction contol (along with other systems) are disabled when this happens. In included pictures of the dash when it happened (note all the warning lights) and of the dash when if fixed itself (no warning light although mil is still on (I haven't cleared it)).

Recurrent intermittent power steering failure and intermittent engine stall. Steering wheel gets stuck when turning right while driving at speed on highway. Steering wheel gets very heavy and requires some force to get it back to center. If I let go of the steering wheel, it would stay in the same position until I move it back. When driving at slower speeds, usually when navigating around turns or roundabouts, the engine will stall and then drastically jolt into gear. Two different mechanics have not been able to identify the root cause. They have checked alignment, electrical codes, and other potential issues without any answers. After research, I believe I am experiencing similar issues as detailed in the safety recall v53 / NHTSA 19v-348 power steering assist. My VIN was not included in the recall , but I believe my car is showing similar concerns. I have requested a local Chrysler dealer look into this issue specifically and I have an upcoming appointment.

A message appeared on the dashboard stating the engine would shut off soon. I could not accelerate. This has happened multiple times (at least a dozen since I bought the vehicle in April 2025) and I cannot drive above 70 mph or it will cause the issue to occur. Several times I have been in multi-lane traffic and because you cannot accelerate, I have to try to park on the should across multiple lanes of traffic at high rates of speed while slowing down.

1215 miles . The adaptive cruise control system was acting sketchy. It failed to maintain proper distance and speed between the vehicle in front. We took it into the dealer who said that the sensor had failed on this brand new vehicle and they replaced it on 2/12/2025. After driving the vehicle when we got it back. There does not seem to be much different. The van tends to accelerate extremely quickly only to get behind the vehicle in front sometimes not keeping proper distance with the way it's set, as well as waiting to the last possible moment maybe 2 or 3 car lengths to break which is extremely scary. Sometimes the warning comes up that says break break . Even with the system said it maximum a car cutting in the system is extremely slow to react. This has led to numerous close calls of rear end collision. We took it back to the dealer on 2/24/2025 1802 miles, who said they couldn't find anything wrong.

Adaptive cruise control slammed on brakes at least five times when nothing there in front or on the sides. First time I ended up with whiplash…now I hear it start to stop and I override system by speeding up. It also sometimes gets so close to car in front without braking so I have to manually brake. I’m concerned about being rear-ended if it slams on brakes for no reason. Five times there were no deer, people, etc.

I was driving on the interstate with adaptive cruise control active. The gasoline engine was running. The vehicle suddenly made a "ding" sound, and the main driver screen displayed an error message "stop safely. The vehicle will shut off soon". The engine shut down and vehicle completely lost motive power. I had to rapidly change across three lanes of traffic to reach the shoulder while losing speed, where I eventually parked with the hazard lights on. As we sat parked on the shoulder, the driver screen screen also showed a red battery-shaped indicator in the upper left, and an orange speedometer with an exclamation point in the upper right.

Crash info - 12:50 am, 2024. 2024 Chrysler Pacifica touring l components failed: airbags non-deployed; steering control module; tcs system; fwd collision avoidance & lane departure; + not avail to inspect. Car sold at auction. Obtained black box & obd info. Car owned by ean holdings, llc. - enterprise rac. Problem not reproduced, car not drivable after crash. Did not notice any warning lamps, too busy trying to keep car on road. My wife was heading home after some late-night shopping when crash occurred on 2-lane dry & clean asphalt country road. Weather was a cool and clear moonlit night. Posted speed limit 45mph. With her headlights on she could see very well far up ahead & knew her surroundings, where the roadside became grass on the left, & a drainage ditch to the right side. She chose out of caution to drive near the center line in the roadway to give ample distance between the passenger side of the car and the soft shoulder to the right. Approx. 150 ft before she approached the turn to the left, she felt a sudden & very intense tug from the right rear wheel. This caused the car to jerk out of control, shoving its back end to the right. It was impossible to correct the vehicle's course & what the car decided to do on its own accord. The car then proceeded to yank the steering wheel hard to the right (while she fought to keep the car turning left), and it forced her off the right shoulder of the paved road, across a 3-foot soft shoulder on the passenger side of her car. The car continued traveling off the road and over a gravel and corrugated drainpipe, landing her in a deep 5-6' irrigation ditch, and abruptly stopped on an uphill slant, making contact with a small sapling tree/weeds. The ride was so violent from all the jarring & bouncing that everything inside the car was flying around like in a front-loading washing machine. She had to exit via the back pass side door. Airbags did not deploy & car required towing. By the grace of god, she did not die!.

I had a warning telling me to stop safely and that the vehicle will stop soon as well as the start\stop and battery lights.

The contact owns a 2024 Chrysler Pacifica. The contact stated while driving approximately 55 mph, the braking system erroneously activated causing the vehicle to abruptly stop. The failure had occurred on several occasions while driving on the same highway. The contact stated that during the failure, the forward collision avoidance: adaptive cruise control was not activated. The vehicle was taken to the local dealer who was able to duplicate the failure, but the cause of the failure was not yet determined. The manufacturer was notified of the failure. The contact stated that the vehicle had been modified to accommodate a disabled driver and did not believe that the failure was related to the modification. The failure mileage was approximately 800.

Ghost braking. While driving on the road using the adaptive cruise control, the van initiated its braking system as if someone was in front of me. This happened with nothing in front of me for miles in sunny cool weather and while at night passing a car with fog. I assumed the fog case had some bearing as the car I was passing their tail lights appeared to illuminate the fog to a degree you would think was a car in front of me. Glove box needed to be replaced. Kept opening and slamming on my bride's chins. The trunk is soaking up water from an unknown source after heavy rains and car washes. We noticed the issue when we vacuumed the rear trunk space and took out the mat. We dried it at the local car wash and didn't think much of it until we went through a car wash again. And there was the leakage but unknown from where.

While travelling on a controlled-access highway at 70 mph with the adaptive cruise control active, and no other vehicles or objects nearby, the braking system engaged spontaneously (without driver input) and forcefully, for approximately . 5 seconds, also engaging the anti-lock brakes. The rapid deceleration was forceful enough to snap my family of 5 all into their seatbelts. The speed of the vehicle slowed approximately 10 mph or more during this incident. My family and I were fortunate enough that no vehicles were behind us, no collision occurred, and I was able to maintain control of the vehicle though I was very much surprised. No warning indicators nor messages appeared. I took the vehicle to a servicing dealer three days after the incident for inspection/diagnosis. I was told be the service agent at the desk that, in order for this to not happen again, I should not use the adaptive cruise control. The technician, who was at the service desk, stated he was unable to reproduce the incident on test drive, and that he recalibrated the adaptive cruise control system and sensor, without further explanation as to what that meant.

It started on or about September 17, 2023, the van's adaptive cruise control, forward collision, automatic breaking is warnings show up on the dash after driving the vehicle about 10 minutes. It does it every day that I drive the vehicle. I have looked up causes and repairs online and there are many complaints about this issue and also after paying a couple thousand dollars at the dealership, it will work for about six months then start happening again. Also unable to use cruise control while driving on a trip, the crusie control will quit operating about ten minutes after the car starts and while driving it.

There have been several incidents that have to do with the electrical components site, such as the adaptive cruise control not working the lanes assist going off, stating that my hands are on the wheel. When my hands are on the wheel, there have been problems when I go to put it in drive. It'll switch back to park and throw on my parking brake. It has also the auto breaking lights have. Come on, my checken and light has come on. It taking in to the dealership and they found corrosion on some of the wires, replaced them. They also replaced the adaptive adaptive control module. It was supposed to magically fix all my electrical problems. Yet I'm still having electrical problems also my navigation on. A scream down by the cluster cluster. Stays on and doesn't go anywhere. I also have video and pictures and things like that of the situations that have gone on with my van 4 months and nothing has been fixed. I've been told by the dealer and buy a representative from Chrysler. That's my van is fine. There's nothing wrong with that. But clearly there isn't an electrical issue and. And I pretty god. Nothing happens to me or my family or someone else because of it. Also, the radio, when you shut your car off and open the doors to exit your vehicle, the radio is still left playing and should not also the auto break in just comes on. For no reason. It happened on the interstwhen we were merging in the traffic. And there's no reason it should be doing some of the things that it's doing.

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.

Https://youtu. Be/xbkibgv3d4g hi team, I recorded this video on my new 2023 Pacifica hybrid limited which I purchased on Jan 17th. (I traded my 2017 Honda crv exl and remaining amount financed with bank) the very next day I got these alerts while it was parked in my garage, the vehicle freezes all of a sudden, the bunch of alerts popup saying the safety features unavailable like, blind spot monitoring, active lane keeping, cross traffic alerts, forward collision, etc. At the steeting doesnt move. I took to the dealer on Jan 18th and they were not able to figure what was going on, it was with dealer for 3 days 1/18, 1/19 and 1/20. The dealer cleared the check engine light and gave back the vehicle. On Jan 22nd, the second time I got, I recorded as a proof of the issue to show the dealer. . Read more...

The contact owns a 2022 Chrysler Pacifica. The contact stated that while driving at 80 mph with the cruise control activated, the vehicle experienced phantom braking. The following day, while driving at an undisclosed speed, the vehicle was vibrating and the brakes failed to immediately stop the vehicle. The contact stated that the brakes caught fire, and there were flames coming from the brake calipers. The contact was able to put out the fire with a hose. The vehicle was towed to the dealer, where it remained for twenty-one days; however, no cause of failure was found. The failure recurred, and the vehicle was taken to an independent mechanic, who recommended the contact stop driving the vehicle as it was unsafe on the roadway. The vehicle was not repaired. The manufacturer was made aware of the failure and dispatched an inspector to the dealer to inspect the vehicle, but the report was not yet available. The failure mileage was approximately 13,000.

I was driving in stop and go traffic about 4 hours into a road trip on i95. At around 60mph, an error popped up on the dash saying “service charging system” then it quickly went away and said “shift to p to start” at which point I lost all propulsion. I was in the left lane and had to make my way to the side of the road with my family of 6 in the car. This was extremely stressful and dangerous as I had no way to accelerate and was stuck to coast. I flipped on my hazard lights and was able to navigate to a safe place under an overpass. At this point, I completely cut off the car and restarted it. It worked fine again upon restart, but the check engine light remained there after. The incident happened again on a side road at around 40mph on the same day. I coasted to a stoplight and had to power cycle the car 3 times to get driving again. The following day, I went to a local Chrysler dealership and they are still in the progress of diagnosing, however they won’t have a response until after christmas. So, I’m being directed to rent a vehicle until the van is deemed safe to drive again.

Steering wheel buttons began no working. Lights on steering wheel flicker when steering wheel turns. Randomly alerted that "adaptive cruise control is unavailable" both when the system is in use and when it is off. Forward collision warning system active breaking not working.

Sept. 12, 2022 - ever since we have owned this vehicle, we have experienced this issue with the cruise control. Speed increases while driving downhill highways and sometimes on pretty level highways. When I decrease the speed on the controller, it sometimes maintains the speed for several seconds (slow to respond) in order to slow down while coming up behind another vehicle. I therefore need to break or turn off the cruise control. Very unpredictable. Also, speed changes a lot which sounds like shifting gears back and forth while going uphill. I had contacted the dealer originally and was told this is normal. This is ongoing. Happens every time when driving on the highway. Safety concern. The other issue we had experienced while driving on a city street, we got some odd sounds, what sounded like it was coming for the transmission. Like shifting sounds. And on another couple of occasions, we got a kind of (clunk) noise. Not sure…hard to explain. Only happened a few times over the last several months. And was brief. This in not ongoing, but a concern for failure and or safety. No warning lamps or messages.

While driving on the freeway using adaptive cruise control, the display indicated that the adaptive cruise control was canceled. I did not cancel the adaptive cruise control. The vehicle decelerated and appeared to turn off completely. The gas peddle did not respond, I was unable to accelerate. The screen then displayed “push button to start”, as though the car was off. I was able to pull onto the shoulder of the freeway, toggle the car into park, and press the start button while pressing the break. Then, the screen display battery light and check engine light turned on. The display said automatic high beams disabled. The vehicle would not respond to pressing the start button while pressing the brake. Finally, I held the start button down while pressing the break for a long period of time. My seat moved back automatically like the car was turned off. I was then able to restart the car and drive to the nearest exit. This is a very dangerous problem that needs to be thoroughly investigated. I am fortunate I was able to get to the shoulder of the road without causing an accident. The vehicle is currently at the nearest dealership, we are awaiting news of the cause.

While driving on highway at approx. 75 mph using adaptive cruise control, the red power cord shaped warning indication appeared on the instrument panel. At the time the warning appeared, the vehicle was in battery powered mode. At the same time the warning showed, the electric motor stopped providing power. The vehicle did not transition to hybrid mode (gas powered), and depressing the accelerator did nothing. The vehicle began to slow from highway speeds, while other cars were in the vicinity. While all this was happening, the "d" on the gear selector was flashing. There was also a message saying to put the vehicle in park to restart, however, I did not want to attempt that at highway speeds. Other systems seemed to operate as normal, brakes worked, the electrical system seemed to be functional other than the described fault. I pulled over to the shoulder and stopped the vehicle completely. I turned the vehicle off, then on again, and was able to put the vehicle in drive without any faults occuring. Normal operation resumed after that.

Honestly it’s been one thing after another, including engine, power train and electric issues.

Hi, I received a recall notice in February 2022 (z11) related to a fire potentially originating in the center of the vehicle underbody with the ignition in the off position. A resolution to this defect has just become available which would require the car (Chrysler Pacifica VIN 118706) to be kept overnight by an authorized dealer. My complaint deals with that no deal can provide a rental car that is of equal size to accommodate my family of 6 with four kids using car seats. I was told that an car of equal size cannot be provided and would have to pay for a rental out of pocket. Why would the cost not be covered by the manufacture that is attempting to resolve an issue created by them. I have kept my part of the agreement by making my monthly car payments and paying the car off with no issue. It seems to me that the manufacture has no regard to the buyers of their vehicles after the sell is complete. I am looking to have the recall corrected and to have a rental car of equal size provided by the manufacture, since they are holding my car as they fix their mistake. Let's take ownership of our mistake and do the right thing. Thank you for helping with this recall.

The electrical system for the Chrysler Pacificas are dangerous. Beyond the other dangerous recalls, my horn and cruise control no long work intermittently. I learned this while trying to warn a driver that was cutting into my lane without seeing my vehicle and I couldn’t warn them that they were about to hit me. Also cruise control stops randomly. This all started after previous recall repairs. Since I am unable to use my horn in an emergency, I am nervous that my airbag no longer functions. This is a common issue reported online. This all started after previous recall repairs.

Lane assist and forward collision warning would intermittently turn off along with the passenger window automatically going down. Vehicle would also seems to glitch and restart at the same time. After this taking place for a couple of weeks, now the vehicle has twice completely shut off while driving. The engine, screens, dash, etc. All turned off and the it was automatically put into park. Vehicle will restart and everything seems back to normal once it is restarted.

From a stop at a stop light, when light turned green accelerated to about 18 mph (going straight through light) then lost all power (with accelerator still depressed) while in middle of the intersection. At that same time a notification displayed on the dashboard for about 5 seconds stating "adaptive cruise control (acc) off". After about 5 seconds notification disappeared and power returned to vehicle. This exact issue happened twice in the same day.
