I have a 2018 Chevrolet Colorado lt 4wd crew cab. Multiple times on a cold start the engine is misfiring. The check engine like comes on, the vsa, and t/c lights all come on and a notification on the dash saying stabilitrak is disabled. The vehicle shakes terribly. The check engine light will flash and then go solid. I am an automotive technician. I know that a misfire should set a hard dtc. When the vehicle is turned off and started several hours later there is no check engine light or any other light on. The dealership in marysville, OH had my truck for 3 days and told me they cleaned a bunch of terminals at several connectors. Whatever that is supposed to do. They said they started the vehicle several times after and everything was good. The next day after I picked the truck up, it did the same exact thing! extremely frustrating! I know a continuous misfire let's unburned fuel into the catalytic converter which leads to premature breakdown of the catalyst. So my question is what is being done about these issues? another issue is with the transmission. On a cold start there is a clunk noise. Then when you are driving at cruising speed and you let off the throttle and depress throttle again there is a shudder. Also, when you come to a complete stop the vehicle tries to jolt forward. This is extremely concerning especially on a vehicle with roughly 18,000 miles on it. This needs to be addressed promptly!!.
