Over the past 12 months, I have observed repeated electrical issues with my colorado. Intermittently, while driving, the dash will display various alerts ( Service 4wd, Service Stabilitrak, Service trailer brake system, steering assist reduced drive with care.) On top of those alerts, the speedometer and tachometer stop giving readings, the AC stops working, the light on the gear shift goes out, and the transmission begins to shift very roughly. Once I get the vehicle to a stop and attempt to turn the truck off, the keys won't release. After 5 mins or so the keys will eventually release and if I let the truck sit for 20-30 minutes the symptoms go away and the truck begins working again... until symptoms appear at a later date.
Despite the fact that this two-year old Colorado has been taken in to service this issue on 6 different occasions, up to this day, the issue has never been truly resolved. I believe the root cause for the issue has never been found. The few times it has been in almost every electrical module has been replaced. Additionally, one dealership found corrosion on a wire harness connector that they cleaned up and believed it to be root cause... apparently not.
Has anyone experienced this or had issues like this? I have photos attached plus a youtube video of another colorado, of the same year (Non- diesel), having the same issue.
Thanks in advance.
