2022 CHRYSLER PACIFICA Forward Collision Avoidance Automatic Emergency Braking Problems

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...

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

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.

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...

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.

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.

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...

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.
