We purchased a 2019 Chevrolet Colorado December 2022. Beginning in January 2023 to current month July 2023 the vehicle has been at the dealership 4 times for the same occurrence: SERVICE STABILITRAK and ENGINE POWER IS REDUCED A warning -??ding-?? sounds (the same noise as seatbelt, door ajar, etc) simultaneously with the messages -??SERVICE STABILITRAK-?? and -??ENGINE POWER IS REDUCED-?? The vehicle immediately is jerking or lurching, the engine no longer runs smoothly and is misfiring. The engine power reduced does not allow safe acceleration, and the vehicle is unstable (as it moves it feels like driving over a thousand speed bumps over and over), the engine misfiring is heard from the exhaust and the vehicle is visibly vibrating, on acceleration the maximum speed is 20 mph. All 4 times this has happened while driving the vehicle on highways in traffic. We are left unable to get out of the way of moving traffic, unable to accelerate, change lanes or make turns safely. Three of the four times we had the vehicle towed to the dealership. The last time the vehicle did this fortunately I was near our local dealership and drove it less than a mile so the service people could -??witness-?? what I had been trying to explain what-??s been happening with this vehicle. This is a very serious issue! My husband is 75 and very ill. I have to drive him 100+ miles for treatments on a regular basis. We cannot continue to be put in danger because of this vehicle default. We need this problem fixed not only for ourselves but for the safety of others, including unsuspecting drivers and innocent passengers, young, elderly, disabled, some simply misunderstanding our vehicles -??failures to perform-?? in traffic on the roads. A trusted vehicle is very important. A stabile vehicle with sufficient engine power is a must if we are going to put it on the roads. -??SERVICE STABILITRAK-?? and -??ENGINE POWER IS REDUCED-?? is not new. General Motors needs to take action to correct this problem and educate dealers.

The stabitrac system malfunctioned and went into low power mode while on the highway almost in an accident because of speed loss. The button to turn it off did nothing. Still unsure what caused this to malfunction but needs to be a way to override to maintain speed without power loss
