I have had this happen twice in the last few months, most recently in the last three weeks. I was driving on a 45 mph highway with the cruise control set at 49 or 50 miles per hour. On the most recent time, I was coming to a red traffic light and applied the break to slow down. However, the van kept going forward even though I was pressing the break pedal totally down. The van slowed somewhat, but the van kept going. I put the van in neutral and was able to stop, but the engine kept going, presumably at the speed set on the cruise control. I stopped the engine By putting the vehicle in Lo, which I believe shut off the engine. By that time I was partly in the intersection. Luckily I had no cars in front of me or behind me, and no one was crossing in front of me. Otherwise I would have had a collision. I called and made an appointment at my dealership, [XXX] on XXX. They test drove the van but couldn't duplicate the concern. According to the Invoice, they "Captured VSR No DTCS related to concern. Checked for sofware updates, None related to concern. Checked for SBS or star cases related to concern. None found." The summary concluded:" System is operating as designed at this time. Updated TCM, BCM and PLGM." I don't know what all of that means, but I think that they did a thorough inspection of my van and couldn't find out what was causing the Cruise Control to not shut off. I did some research online and I found that there were 2 recalls in 2018 for the 2017 and 2018 Chrysler Pacifica that appear to have attempted to correct this exact issue, but it showed that my vehicle, with my VIN, was covered by FCA Safety Recall U64, the federal safety agency 18V‑332 and the recall status showed that my vehicle was "Repaired." Has anyone else had this problem, because this creates a very scary, dangerous event. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Hi! This vehicle stopped twice in the middle of a road on its own. Vehicle was driving fine and the next second it slowed down and wouldn’t accelerate as I would push the gas pedal. It’s as if the engine shut down due to the car signals not transmitting correctly. The screen started blinking on and off giving me warnings and one of them said “Service Shifter!” My safety and my children’s safety was put at risk because anyone could’ve hit us from behind as the car started decelerating on the road with oncoming traffic. I towed the car to a mechanic as the car does not run properly while being driven, and the mechanic said it has multiple electrical issues and multiple leaks. The vehicle was inspected by my own mechanic, as the dealer also inspected it and they tried to connect the scanner to turn off the engine light and get me to drive off. They have refused help and I truly believe they knew this car was a safety hazard. After leaving the dealer, 4 minutes into driving the car started slowing down and I was able to make it into the parking lot, but got stranded in the middle of the street where opposite traffic comes into. I bought the car 03/01/2025. The check engine light turned on 2 weeks in. The battery seemed to be drained 2 weeks in but it did not need cables or recharge, it’s as if the battery loses connection. Then at the one month mark it started having those issues, no warning until it completely stopped on the road. When it stopped on the road, that’s when the screen started going off with multiple warnings.

The vehicle is available for inspection. At an intersection the vehicle abruptly turned off, while the engine was running and in drive. Children were in the vehicle and I was very scared and in shock when it happened. My car just randomly turned off, while I was sitting in the middle of an intersection and the vehicle was in drive (obviously). I was able to turn it back on, but it was very dangerous and could have killed us if a car had come through the [XXX] intersection while we were stuck there. Safety of other drivers on the road at risk, my life and children’s lives were at risk. Could have caused death had our van been stuck in the middle of this busy intersection a few feet more forward.

I was driving my car and approached at a stop sign. The car stopped and froze. The shifter knob lights were out and I was unable to move the car or shift the gears into neutral . ( The engine turned on ,but I could not move my car.) I had the car towed to my autodealership. Since then, the car has repeatedly started, but the shifter is frozen. My dealership has spent a month telling me they don't know how to fix the car. The dealership has been trying one thing after the other, they tell me, yet within a week my car is not functioning. The dealership installed new programming. a week ago.. A few days afterwards, while I was slowing down in city traffic, the dashboard filled with error messages and the car became extremely bumpy to drive. Today, I just had the car towed again to the dealership. The car started, but the shifter was not functioning with an error message "Service Shifter." The car shifter randomly worked once the tow truck arrived, but still had the engine light on. I await to see if the car can be fixed.
