Owners report a wide array of electrical and safety system failures in the 2023 Chevrolet Colorado. The most critical and recurring issue is unintended automatic emergency braking activation, where the forward collision avoidance system slams brakes without obstruction present—sometimes from highway speeds down to 15 mph. Multiple owners sustained neck and wrist injuries; one narrowly avoided running a stop sign. These events occur unpredictably despite completed recall repairs. Dealers struggle to duplicate the failures during short test drives, making diagnosis difficult, and some have responded by advising owners to manually disable the safety system before each drive.
Digital display blackouts leave drivers without speedometer, fuel gauge, or headlight controls—critical safety information. Some failures follow botched over-the-air software updates. Blind spot monitors malfunction constantly, flashing false warnings when no vehicles are present, and paradoxically disable window and door lock controls when active. The turn signal stalk reverses direction after completing turns, triggering false lane-change signals to other drivers. Complete electrical shutdowns with melted fuses have occurred at low mileage, rendering vehicles inoperable roadside with unresponsive brakes. Battery drain overnight, failed camera systems, fuel splashing during fill-up, anti-theft alarms sounding with no trigger, and wireless charging failures round out the electrical issues. Dealership responses have ranged from unable to duplicate the problem to advising drivers to work around the faults rather than fix them.
Failure modes owners describe
Unintended Automatic Emergency Braking Activation
The forward collision avoidance automatic emergency braking system activates without warning or valid obstruction, causing abrupt hard stops at highway and city speeds. Occurs unpredictably, sometimes after recall repairs. Dealers cannot duplicate the issue in short test drives despite owners experiencing it repeatedly over thousands of miles.
When: Primarily between 5,000–15,000 miles; some as low as 2,800 miles
Symptoms owners cite: Sudden hard braking from 50–55 mph down to 15 mph; Brakes lock up with no vehicle or obstruction ahead; Forward Collision Warning light illuminates; Vehicle comes to complete stop mid-drive; Neck and wrist strain from abrupt deceleration; Beeping and stopping at shadows on ground (per dealer observation)
Codes mentioned: Forward Collision Avoidance system fault, Front camera module malfunction
Repairs/costs cited: Front camera replacement (per recall), electrical system reflash, front collision wiring and ECU replacement attempted; failures persist post-repair. GM technical engineer directed owners to manually disable emergency braking controls in console before every drive.
Recalls/TSBs owners mention: NHTSA Campaign Number 24V133000 (Electrical System, Forward Collision Avoidance) issued; recall repairs performed on multiple vehicles without resolving the failure. GM diagnostic engineer suggested disabling safety features as workaround rather than fixing root cause.
Digital Display and Infotainment System Failure
Instrument cluster and infotainment screen go blank, lose functionality, or display incorrect information while driving. Speedometer, fuel gauge, and headlight controls become inaccessible. Some owners report unexpected software update causing battery drain. Screen blackouts lasting 30 seconds to 1 minute render critical safety information unavailable.
When: First occurrence 5–6 months after purchase; varies between 554 miles and 7,500 miles
Symptoms owners cite: Dash cluster goes completely blank while driving; No speedometer, fuel gauge, or console information visible; Infotainment screen unresponsive; Speedometer alternates between MPH and KPH; Screen blacks out intermittently during operation; Inability to access headlight controls; Over-the-air software update causes battery to drain while parked; Screen glitch requires 10+ minute battery cable disconnect to reset
Codes mentioned: Software glitch (unspecified), Battery drain after OTA update
Repairs/costs cited: Dash and radio component replacement performed on some vehicles; no lasting fix. Temporary solution: disconnect negative battery cable for 10+ minutes to restore display. One owner reported dealership saw issue in multiple 2023 Colorados.
Recalls/TSBs owners mention: Software updates issued; failed OTA update on 7/24/2023 weekend caused battery drain. Dealership stated no problem found after computer system update in at least one case.
Blind Spot Monitoring System Malfunction
Blind spot warning lights activate continuously or intermittently with no vehicles present. System becomes unreliable and distracts driver. Often linked to window control and door lock failures. More frequent after dark. Firmware updates do not resolve the issue permanently.
When: Occurs unpredictably throughout ownership; worsens in low-light conditions
Symptoms owners cite: Both blind spot mirror warning lights illuminate with no vehicles nearby; Blind spot light flickers continuously after dark; Light activates when trees or traffic signs enter view; Blind spot activates more during braking or deceleration; Double-flash pattern when no vehicles present; Light toggles on and off randomly; System fights lane changes when lane assist is active
