2021 CHRYSLER PACIFICA Forward Collision Avoidance Problems

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

1. This vehicle was recalled for a software update due to the rear camera failing to operate at times. The software was updated by the dealer. However, this did not completely fix the problem. While the camera fails less frequently, it still does not energize at times. I took the vehicle back to the dealer. I was then informed that there is water intrusion into the rear lift gate, which causes the electrical to short out. I was told that I would have to replace the wiring harness which energizes the camera as well as the rear vehicle lights. I have not noticed any problem with the lighting as of yet. However, I have been told that this is a problem with the Pacifica in general, as well as the Durango. I was told that replacing the harness would not guarantee that the problem would be solved as there would still be water intrusion, which could cause the problem again, even with replacing the harness. This is obviously a safety issue, as the camera fails to operate at times, and there is a potential of losing lighting on the back of the vehicle. This is also a known defect by Chrysler. 2. When using the Adaptive Cruise Control on streets and highways with multiple lanes traveling the same direction, the vehicle will brake suddenly and hard when the vehicle in front of me changes lanes. This occurs after the vehicle in front of me has completely changed lanes and is not impeding my forward progress whatsoever. My vehicle speeds up to the set speed and then violently brakes as if it is about to crash into the vehicle ahead of me, even thought the lane is completely clear. The vehicle has been inspected for this scenario. I was told that it didn't perform as described above when the technician drove it. This is a safety issue as the vehicle suddenly and violently brakes at highway speeds, with traffic behind me.

My vehicle has no back up camera or blind spot warning. Took to dealer for recall and they said they were only responsible for a software update and not solving the recall problem. My vehicle still does not have either of these functions. I was told I would have to pay for the repairs for this recall.

My Pacifica completely shut down. All the warning lights came on such as crash detected, ABS light, and the windshield wipers came on. The vehicle was towed to the dealership that I bought the vehicle from. They completed a hard reset of the vehicle, and I took it home. Two days later it did the same thing all the lights came on, but it allowed me to drive it to the dealership. Still waiting to see what they think the problem is this time.

I was backing out of the driveway. I had all the safety features on, and I was checking my surroundings. Typically, the blind spot and front sensors would alert me to dangers. However, on this and many other occasions the warnings didn't alert me to danger on my passenger side that I couldn't see. this resulted in damage to the front quarter panel of my van as well as damage to the bumper. The body shop said it would cost at least $5000 to repair the damage. I can't afford that; in turn I am driving around with the damage.

The forward collision alarm was triggered when there was no collision. Additionally the ABS system and cruise control went offline. This occurred numerous times during winter while at a full stop as well as when driving between 45-55mph. Once triggered the collision alarm remained on for hours to days at a time. During that time cruise control was not able to be used and ABS was offline. Additionally the assisted parking was not available. ABS and stability control is important for safe driving and braking in icy/slippery situations putting both my own, my passengers, and other drivers at risk. The vehicle was inspected 4 times by the Bath NY Chrysler dealership. A sensor was replaced the first time but this did not correct the issue. The 2nd time another component was replaced, but the technician stated the issue was still present and I would need to bring it back in for further testing. The 3rd and 4th time the dealership was not able to recreate the issue and did not perform any repairs. The issue has recurred, but the dealership was not able to get the car in at that time. This vehicle has not been inspected by manufacturer, police, insurance etc. There was no prior warning to the issue. When it occurs the warning lamps that come on are: BRAKE, Front Collision, Front Collision OFF, ABS, Seatbelt, and the Traction Control. I have a photo of the dash from one of these incidents.

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.

On empty roads at low speeds, vehicle flashed emergency braking signs and stopped abruptly. Happened multiple times in January both in reverse and when driving forward normally. Safety of driver and passengers was impacted by the sensor issues and abrupt braking. If there were other cars behind the vehicle, it could cause accidents and injury. Vehicle was brought into dealership and could not identify or address the issue. Suggestion provided was to disable the sensors while driving.

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.

This vehicle programming includes forward and rear collision warning with both audible and dashboard diagram lights showing which sensors are approaching another object. Unfortunately, in practice, the alarms alert you to something in front or behind you regardless of if you are in gear to move forwards or backwards. This means that everytime you get in gear to leave your parking spot the alarm is dinging because of whatever you pulled up to in your parking spot making drivers have to tune out the audible alarm which is irrelevant and look down at the dash to see where the alerting object is in relation to the vehicle. Reports have been filed with Chrysler but no action has been taken to improve this poor design despite years of it being in effect.

The first incident, the vehicle lost power driving down the freeway at 75 miles per hour. That was only at 1,000 miles. Very scary!! Since then, I have had numerous electrical issues- too many to count. There has been front & side sensor collision warnings when nothing is even next to my car. The navigation has not worked the majority of time that I have owned the car. travel for work so I therefore have to look at my phone for directions- not ideal at all for safety. I had had a few instances of an extremely loud humming sound from the vehicle of unknown origin. I have had the control screen frozen & could not turn on heat in winter. I have most of these occurrences on video with my phone. I had sent a certified letter requesting arbitration. I have had no response from Chrysler. I had the car in 7 times to the dealership. They told me they cant fix it & dont waste my time returning until there is recall. I have these incidents in movie or video form. Your form will not allow me to upload these videos- only still pictures.

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.

My 2021 Pacifica PHEV has 16,200 miles on it at time of incident on 10/31/2022. I had just pulled off the highway to get gas when the issue began. I received a “service electrical system” on the dash and a check engine light and I had to turn off and back on to get it to restart. The check engine light stayed on and upon continuing my drive home another warning light came on telling me that the emergency braking was no longer operating. The warning light stayed on for a few miles and then went off. I took snapshots I will include. I also noticed that the vehicle was recording erroneous data such as suddenly having an electrical charge of a large percent when I had zero electrical charge. I got the vehicle to the dealership for repair. On 11/1. No loaner or rental reimbursement was available from Chrysler so I was without a Vehicle during repair. I received the vehicle back on 11/3/22 and I was informed that the vehicle had error codes POE 15-50 Hybrid/EV battery pack coolant heater A control and P1649-00 (? Not sure I wrote the number correctly) HCP Int… code. The paper also showed POE 15-00 HVAC Blocker Power but he only mentioned the first 2. The service technician indicated that the vehicle had a Z76 recall (I was not aware of a recall) and that they had done a software update to fix it and the vehicle should note be fixed. Upon reading other online complaints I see multiple reports of the same thing happening repeatedly to other 2021 phev Pacifica’s with low mileage while driving at high speeds including within 10 miles of having the same repair done. I am now scared to drive this vehicle on the highway after reading of multiple other 2021 PHEVs no longer operating on multiple vehicles while at highway speeds, despite multiple attempts at repair. I am afraid for my safety and for anyone else in my vehicle and I I want Chrysler to pay off my note immediately and take back possession of the vehicle. I no longer feel safe driving it.

I was on the highway traveling at 60mph, with the adaptive cruise control on. The semi in front of me began to brake, I tapped off the cruise control and began braking. The semi came to a complete stop and I pushed my brake pedal to the floor to stop my vehicle. It did not stop. My Pinnacle has emergency braking and forward collision warning. My driver's instrument panel did not give a forward collision warning indication in a timely manner and my emergency braking did not stop my vehicle. At the time of the accident vehicle had less than 10,000 miles, dry weather conditions, and vehicle was used for leisure - in town driving. A month previously, I took my Pinnacle into the dealership because I didn't feel my brakes were working properly. They felt mushy, little resistance, and were making a noise. An inspection was performed by the dealership but were unable to detect a noise or visual issue. My safety was put at risk when a system I depended upon, that was advertised as, "Full speed forward collision warning with active braking assists you by providing both visual and audible warnings as well as applying emergency braking to help bring the vehicle to a full stop, if needed" (chrysler.com/pacifica/safey-security.html) failed. The brakes didn't engage properly to stop us before hitting the vehicle in front of us. The forward collision warning indication didn't happen in a timely manner, it was delayed causing us to lose precious seconds. If this had been a passenger vehicle in front of us we could have injured the occupants and we ourselves could have been gravely injured had we been traveling at a higher rate of speed. The problem has not been confirmed by a dealership, but was taken there prior to the incident less than a month before. I reported the problem to Chrysler the day of the accident. The vehicle is pending inspection by insurance and I have asked that the Electronic Data Recorder be removed and the information on it to be evaluated.

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.
