Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
The intent of this service bulletin is to identify aftermarket ALDL or DLC interface devices as potential sources for causing multiple customer concerns that do not have other diagnostic methods to identify them.

The failure pattern owners describe
The 2017 Colorado's electrical system shows a pattern of interconnected failures. Ignition key sticking appears early (25,000+ miles) and occurs frequently enough that one dealer acknowledged it as a "chronic issue"—yet no recall exists. Owners report needing to restart engines repeatedly or manipulate shifters to extract keys, and one owner's battery drained while stranded at work waiting for a jump.
Wiring harness chafing and rodent damage emerge as a persistent theme. Owners describe Multiple warning lights (Stabilitrak, 4x4, Check Engine), limp-mode activation, steering lock-up, and complete stalls. One owner's truck sat at a dealership for 8+ months because GM discontinued the required harness part. Technical bulletins exist for this defect, and repair costs run $4,000–$7,000.
The infotainment system exhibits ghost inputs—touchscreens change radio stations, switch display modes, and call contacts without user touch. Screen replacements and module swaps fail to fix it. Separately, Stabilitrak warnings and traction control lights trigger with intermittent power loss or power steering failure, sometimes set off by high-beam or window operation alone.
Alternator failure (one owner reported dangerous 15.8V output) and battery drainage round out the electrical picture. A few owners report cold-weather rear-camera failures and parking brake lever contact with harness causing electrical shorts. Dealers commonly charge diagnostic fees and deny warranty coverage on out-of-mileage vehicles, even for chronic design defects.
