Cruise Control problems of the 2019 Chrysler Pacifica

The contact owns a 2019 Chrysler Pacifica. The contact stated while driving at various speeds with the cruise control engaged, the rpm's increased to high without warning. The vehicle was taken to an independent mechanic where the contact was informed that the vehicle was working as designed. The vehicle was taken to sapaugh Chevrolet Buick GMC (1435 mcnutt st, herculaneum, mo 63048; (636) 931-0055) where the mechanic was unable to duplicate the failure. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was 42,323.

Pacifica hybrid, two incidents: first was on freeway, fast lane, driving normally with active cruise control. The car suddenly shut down all acceleration and slowed. I was able to press the brake and stop. The front console lit up with many warnings including the frontal collision warnings. I was not close to car in front of me but a motorcycle had split lane passed me very closely and cut in. I had to power off my car and start it twice before it would go forward. I took car for service, Chrysler dealer found nothing wrong, replaced a computer module, gave it back. Less than one week later, the car again suddenly lost acceleration and braked. Same large set of warnings appeared. But this time the car didn't allow me to press the brakes. I was traveling on city streets less than 30 mph but had lost all acceleration and braking control of the vehicle and continued to roll into an intersection at about 7mph. The brake pedal literally pushed back against my foot. I gave it back to Chrysler dealership where it's been ever since. Car has 1100 miles on it purchased July 14th, registration on 7/16. Approximately 300 miles of the car was the dealership service department trying to replicate the issue. Now Chrysler corporate cares is telling me it's still under diagnosis (car hasn't even been turned on in more than 10 days) and that the only way I would get resolution is through arbitration "a free service". My vehicle is currently waiting for Chrysler star (highest level engineering) to even get to the case. I wanted to report the safety issue with the resolution steps for people to follow but unfortunately I can't. Chrysler might even try to give this vehicle back to me again (which I don't want). Note: dealership has been very stand-up. The problem is Chrysler corporate.
