Automatic Emergency Braking problems of the 2022 Chrysler Pacifica

While I was driving this vehicle on the highway, the vehicle shut off and the engine light came on.

In may 2025 shortly after purchasing this vehicle I had complete brake failure while driving down the road. I was driving approximately 65 mph when the forward collision warning, abs warning, brake warning, auto emergency brake warning lights came on and when I pushed on the brake pedal it was hard as a rock and wouldn't stop the vehicle. It was returned to the purchasing dealership, and they replaced the brake booster. On November 27th of 2025 I was driving down the road and the exact same problem occurred with a complete loss of brake function. It went to the local Chrysler dealership; they replaced the master cylinder. I picked it up 12/10 drove it 5 miles home and parked it. I got in the vehicle the next morning to go to work and on my way to work all the same dash lights came on and I had a complete loss of brake function. It was towed back to the dealership again; this time they replaced the abs module. I picked it up on 12/30 drove 5 miles home, parked it, tried to leave 3 hours later and couldn't push the brake pedal far enough to get the van started. When I did finally get it started all the same dash lights were on and the brakes were not functional. It was towed back to the dealership again and this time they replaced the wiring harness. I picked it up 1/16. Drove it minimally over the weekend, on 1/19 the front-end collision warning lights came on and the check engine light came on while driving 70 mph. The brakes didn't lose function this time, however. The following day I was sitting in line at an elementary school waiting to pick up my daughter when all the same dash lights came on again and I had a complete loss of brakes, it was towed back to the dealership, where it still is. There was contact made with Chrysler engineering during the 2nd repair. The dealership has been able to recreate the problem more than once since they have had it. This put myself and my children a significant risk of injury, and other cars if there was an accident.

At random, the dashboard will light up with a red brake light, the check engine light, front end collision warning, and the abs warning light. It gives me several messages as well. Service electronic stability control, auto emergency braking active braking off, auto emergency braking unavailable service required. When this happens the brake pedal is impossible to push and it takes every ounce of power to get the vehicle to stop. This is no warning that this is coming and it happens most often when you are driving. This puts myself and my family at risk as well as everyone that is driving near me when this happens. It has been repaired 6 times by 2 different dealerships, and it still isn't fixed.

During 3 separate drives (october11, 2024; December 30, 2024, and January 2, 2025) the vehicle shut off while going uphill on an interstate while the engine was at 3,000 rpm. When I pulled over to the side of the highway and stopped the car, the emergency parking break automatically came on. I had to restart the vehicle 2 or more times in each instance. On January second, the vehicle shut down 5 separate times, some on interstate 70 and some on us route 40, all while going uphill between 2000 and 3000rpm. I took it to a local Chrysler dealer January 8th, but they could not recreate the problem or explain why the vehicle was shutting off with no warning.

Week of 6/18/23 vehicle began flashing codes- service electronic stability control, lanes sense unavailable service required, awd system unavailable and several warning lights appearing on dash. Took to dealership replaced star connector. Still same issues. Took to another dealership replaced abs module. Still same issues. Chrysler engineers are guiding dealership on how to proceed but neither the dealership or Chrysler engineers know what is wrong with the car or how to fix it. Has been at 2 dealerships since June 23, 2023 and still no fix. The only repair documentation I have is from the first dealership. The dealership it has been at since June 29,23 said they cannot provide me with a document of the work they have done until the service repair order is closed. That won’t be closed until the car is fixed. But they can’t figure out the issue.

On more than one occasion when I was on a four-lane highway with no vehicle in front of me in my lane, while I was passing a slower moving vehicle in the outer lane, my vehicle slammed on the aes brakes and would have absolutely caused a crash if there would have been a vehicle behind me. That person could have no possibly reacted fast enough to prevent his vehicle from rear-ending my vehicle. Again, there was no one in front of me, only the vehicle in the outer-lane. As far as the rear-cross-traffic problem, my vehicle is one that is missing Chrysler's sphere and rear-parking-assist because of the chip shortage. There aren't any sensors in the back bumper at all and I'm not sure what triggers the rear-cross-traffic alert, but it does not alert until I've backed up so far from my parking space that if there was a car coming quickly it would surely hit me. This system does not work any where as quickly as any other car I've had it on in the past.

While reversing out of driveway with 4. 3 deg. To 5. 5 deg. Down slope, car stopped with rear in street while displaying an apparent rear collision symbol. There was no cross traffic and a car parked along the curb on passenger side was not encroaching on driveway. Car then refused to move either further back to complete the street entry maneuver or forward to re-enter the driveway. Car was left in a dangerous position part way into the street and blocking sidewalk. Car could not be moved until ignition was turned off for 10 seconds, then turned back on. At that point car was first pulled fully forward into driveway, then successfully backed out into the street and driven off.

22' Pacifica has advanced front brake assist . It does not work. I have tried and it only sets off a audible warning noise and dash says brake. No braking assist like it was stated it would have. I took it back to dealership 3 times now and have been told every time it has no codes. This safety braking does not work. The settings are all on . But there is no assist braking at all.
