Chrysler Pacifica sudden acceleration problems

Filed Nov 2, 2026 · Brakes · FL · crash

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle speed control and braking systems malfunctioned. The vehicle experienced sudden unintended acceleration while the driver was actively applying the brakes. The vehicle has been parked, remains unrepaired, and is fully available for physical inspection and Event Data Recorder (EDR) extraction upon request. How was your safety or the safety of others put at risk? The vehicle accelerated uncontrollably despite the driver applying the brakes, resulting in a collision with a parked vehicle. This total loss of speed control and braking effectiveness put the driver and surrounding pedestrians at risk of severe injury or death. Has the problem been reproduced or confirmed by a dealer or independent service center? No. The vehicle has been intentionally withheld from dealership diagnostics and collision repair to prevent technicians from inadvertently clearing the vehicle's computer history, thereby preserving the digital evidence of the malfunction. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The insurance carrier has processed an initial digital claim for the collision damage, but no physical diagnostic inspections or teardowns have been performed by the manufacturer, collision shops, or insurance representatives at this time. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? UNKNOWN. The sudden acceleration occurred without warning while the driver was braking. We have dash camera video footage that captured the incident live and corroborates the sudden acceleration event.

While driving a 2025 Chrysler Pacifica rental vehicle at highway speeds on the interstate, the vehicle experienced a catastrophic electronic throttle/cruise control failure resulting in sudden, violent, and sustained unintended acceleration. The cruise control system completely locked up and would not disengage. When the accelerator stuck, I heavily depressed the service brakes, but the braking system was completely unable to overcome the wide-open throttle of the engine. The vehicle refused to decelerate. To prevent a catastrophic high-speed collision, I was forced to shift the transmission into Neutral while traveling at highway speeds to disconnect the engine from the drivetrain. The incident lasted continuously for over 30 minutes on the interstate as I managed the runaway vehicle. Post-Incident Behavior and Diagnostics: Upon bringing the vehicle to a stop on the shoulder of the highway, the transmission locked and the engine continued to race wildly, pinned at a constant 3,200 RPMs while in stationary Neutral. Tapping or shifting the transmission was impossible. The vehicle refused to shut down normally, forcing me to repeatedly cycle the electronic ignition button under extreme duress before the engine completely turned off. Upon restarting the vehicle, the electronic glitch reset itself and did not immediately replicate. There were 3 passengers inside the vehicle and 2 trailing eyewitnesses in a separate vehicle who observed the illuminated brake lights during the uncontrolled acceleration. This vehicle is a severe public safety hazard and represents a failure of the brake-override safety logic. I have preserved hard video evidence of the dashboard diagnostics and the 3,200 RPM engine racing while stopped.

Auto stall at stop is not working safely on my vehicle there are two issues that can cause safety problems .A) when system restarts engine the vehicle has jumped forward several feet quickly causing very nearly hitting the car in front of me as a traffic light turned green . B) when I slow not quite to a stop making a left turn I have experience very low or no power and could be hit if a car is coming towards me . Both these issues do stop if I remember to turn off the auto stall system but I do not always remember ! I did make a compliant at a Chrysler Dealer they found no issues and did not reproduce the problem no warning lights come up when the problem happens . I have not had damage to the vehicle but have had two close calls one nearly rearending a vehicle at a intersection as my Pacicifca lurched forward and the other as an oncoming car needed to brake when I made a left turn in an intersection and had a loss of power .

2020 Pacifica keeps stalling. From a stop light or stop sign the vehicle will lurch forward without warning. Recently, from a strip mall I stopped before pulling out into traffic and the vehicle lunged forward peeling rubber and shot onto the main road and I had to slam on the brakes to get the vehicle under control. At the next stop light, it stalled and I couldn't get it started. I'm handicapped and I had to exit the vehicle with my canes and advised the driver behind me of the problem. I've made 5 trips to the dealer with this problem. The dealer replaced a crankshaft postion on one trip and the fuel pump on another visit. If you leave the vehicle set for about an hour everything goes back to normal until the next time it stall, which is the next time I use the vehicle. More recently I picked up my vehicle from the dealer on February 14th, put 24 miles on it. I didn't use the vehicle on [XXX]. I then drove six miles on [XXX] for a total of 30 miles and it stalled again. The dealer South Hills Chrysler Jeep keeps telling me they can't duplicate what I'm telling them are the problems with the vehicle. I don't know if it is a transmission or what. I called Chrysler customer service and spoke with a man named Sahil. I explained the issues with the vehicle and he contacted the dealer and parroted what the dealer said to me, they can't duplicate what I am saying is wrong with the vehicle. This was on February 28th. My van has been setting at the dealer since February 18th and I haven't boo from the dealer since. Sahil is to call me tomorrow the 5th of March , but I don't expect any information from him that will resolve the issue. I am [XXX] and [XXX], I need this van for hauling [XXX} for doctor's appointments and other issues that surface. This problem of stalling started back on the middle of November, 2024, again the middle of December, 2024 and again the middle of January, 2025.
