“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…”

“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…”

“The contact owned a 2017 Chrysler Pacifica. The contact stated that while attempting to enter the garage from a stop, the accelerator pedal was depressed and it traveled to the floorboard, causing the vehicle to violently accelerate 7 feet and crash into the garage. The vehicle crashed into the garage, through a wall, garden box, fence, and a mud ground where the vehicle came to a stop. No warning light illuminated prior to the failure. None of the air bags deployed. There was property damage to the garage and walls. No injuries were sustained. A police report was filed. The vehicle was towed to a collision center. The insurance company deemed it a total loss. The manufacturer was made aware of the failure. The failure mileage was 79,828.”

“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.”
