My vehicle stops working while in traffic when the auto stop is engaged. The abs, parking brake, and dash flashes prior to the engine stopping. I have been to the dealership multiple times and they are never able to recreate the issue. The check engine light codes produced are P0014 and c0800-03.

Was accelerating to approx 45-50mph when the vehicle gave no power, but my RPMs were revving. Once removing my foot off the gas pedal and trying to get power back, after the 2nd or 3rd time I resumed power. The car has less than 9000 miles on it. Right after, a message alerted me to have the vehicle brought in for service, and the engine light came on. According to the dealership, the found code P0700 which is normal, followed by P7224, something I am unable to locate anywhere online. They said they tested everything and all came back normal. It's been noted and if it happens again to let them know. I'm not feeling comfortable paying 50K+ for a vehicle to have it go haywire under 10K miles.

Wife was driving southbound on US287 between vernon, tx and wichita falls, tx in a 75mph speed zone. Vehicle abruptly and for no apparent reason slowed as if the brakes had been applied with sufficient force to cause her to bend forward at the waist. Subsequently, the vehicle speed became erratic and she slowed to 25 while moving onto the shoulder. Could easily have caused a fatal accident had traffic not been unusually light. I am enclosing GM service bulletin issued in July of 2020 (I found it posted on the NHTSA web site) regarding the transmission used in this car. A safety recall should be immediately issued.GM NHTSA should have required GM to notify buyers of this condition prior to purchase when the inherent potential defect first became apparent. We bought the vehicle new in question on 2 Feb 21 and it had been driven just 4,063 miles at time of incident.
