Where to start... I bought the truck new in April 2024. At 9,300 miles - the check engine light came on. Took to the local Chevrolet dealer, was told it was a bad pin out on the electric transmission pump. This is part of the AUTO STOP xx and the service manager said - no problem to drive. Ordered parts - allegedly - waited MONTHS. Next trip, new tech showed me where that harness was shorting out against the shroud. Wow. Replaced pump and harness - again, allegedly - I did not see what they did. Drove home, next morning - check engine light again. Back to dealer, more xx from the service 'advisor'. Next day, no call so I called them. Oh, yeah - it's ready. Drove home - next morning, check engine. This has been going on since October 2024 - almost a year. GM is supposed to call me today but, the dealer and GM are not very good about returning calls - we'll see. Only option is lemon law this dud but, that really doesn't help me. I like my truck and would like to keep it but, GM corporate and their dealers, don't seem to GAS about service after the sale.

The truck handles great, on city streets and the highway. I'm short (5'-4") and I feel comfortable in this truck. Great pickup, low road noise.

With 2000 miles on my Colorado the radio malfunctioned. My local service department said GM told them to tell me to wait for GM to come up with an update to fix the software. My radio received an update last week. The update corrected the issue for one day. The next day the same issue came back.
