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
Owners describe a range of electrical gremlins, with two patterns standing out as critical: sudden complete power loss mid-drive and cascading charging-system failures. One owner lost all electrical power twice while driving—vehicle shut down, then restarted after five minutes with the dash clock and radio reset to factory defaults. Another owner's alternator ran high and failed again after replacement, triggering a cascade of warning lights (ABS, traction control, stabilitrack, battery) before the vehicle stalled at a stop and locked down completely—doors locked, windows inoperable, no hazard lights—leaving the owner trapped for a minute until power returned.
A third complaint traced electrical chaos back to water leaking into the driver-side fuse box from the roof antenna mount, corroding it and triggering reduced-engine-power deration to 20 mph. Trailer brake system warnings are widespread and persistent, beeping nonstop in rain or cold weather, sometimes accompanied by voltage issues and starting problems. Owners also report intermittent instrument cluster blackouts, backup camera blinding at maximum brightness with no dimmer control, door-lock failures, and random starting clicks instead of cranking. None of these failures have been reproducible at dealerships, yet owners confirm they occur repeatedly in real-world driving—a gap that has frustrated multiple owners into abandoning their vehicles due to safety concerns.

Failure modes owners describe
Complete power loss and shutdown while driving
Vehicle loses all electrical power mid-drive, forcing an involuntary stop. System resets after 5 minutes (clock resets to 12:00, radio returns to defaults). Multiple error codes present before events, including stabilitrack warnings and remote-start service messages.
When: During operation; not reproducible by dealers but owner has reproduced it multiple times
Symptoms owners cite: Complete loss of all electrical power while driving; Vehicle stops unexpectedly and cannot be restarted for ~5 minutes; After restart, dash clock and radio settings reset to factory defaults; Stabilitrack warning messages may appear before failure; Remote start service messages observed; Multiple error codes present
Codes mentioned: Stabilitrack warning
Repairs/costs cited: Mechanic cleared error codes; issue reproduced after clearing. Remote start antenna suspected by dealership but not confirmed.
Recalls/TSBs owners mention: Dealership suspected remote start antenna as cause; no confirmed recall or TSB mentioned
Alternator overcharging and battery electrical cascade failure
Original alternator runs high (outputs excessive voltage); replacement alternator from aftermarket source also runs high within weeks. Triggers cascading electrical warning lights (ABS, traction control, stabilitrack, trailer brake, battery light) and eventual stalling at stops. Vehicle loses all power (cannot unlock doors, operate windows, or activate hazard lights) for ~1 minute, then click sound occurs and dash lights return before restart is possible.
When: Original alternator failed by December; replacement failed within weeks; issue now occurs daily after ~1 year of ongoing problems
Symptoms owners cite: Battery gauge climbs to maximum during operation (requires 20+ min of driving to trigger); Multiple warning lights illuminate: ABS, traction control, stabilitrack, trailer brake, battery, tire pressure; Loss of driver-assist features; Vehicle stalls when coming to a stop; Complete power loss: doors lock, windows inoperable, hazard lights unavailable; Radio screen goes black first, then heat cycles in/out before full shutdown; Cannot restart for ~1 minute; Click sound audible from dash after power loss (with no key in ignition)
Repairs/costs cited: Original alternator replaced; aftermarket replacement (Parts Geek) failed similarly. Owner has been to dealership 3 times and garages 6 times over 1 year. Ongoing issue unresolved despite repeated repair attempts.
Recalls/TSBs owners mention: Chevrolet referred owner to dealership; case opened with dealership after NHTSA contact
Roof antenna water leak causing fuse box rust and electrical failures
Water infiltration at roof antenna mounting point corrodes driver-side fuse box, causing widespread electrical failures including engine power management faults.
When: Mileage unknown
Symptoms owners cite: Check engine light illuminates; 'Reduced Engine Power' message displayed; Vehicle deration to 20 MPH max speed; Accelerator pedal sensor fault codes present
Codes mentioned: P2138 (accelerator pedal sensor failure)
Repairs/costs cited: Owner initially replaced accelerator pedal sensor; failure persisted. Dealership diagnosed water leaking from roof antenna into driver-side fuse box, causing corrosion. Vehicle repaired by dealership.
Recalls/TSBs owners mention: Manufacturer notified; owner referred to NHTSA
Trailer brake system warning light recurrence and vehicle shutdown
Trailer brake system warning illuminates repeatedly and continuously, triggering persistent beeping and dashboard flashing that obscures speed display. Warning resets and re-alerts in rapid succession. In some cases, triggers complete vehicle shutdown and inability to start. Problem escalates in rain or cold weather.
When: Occurs frequently, especially in rain or cold; one case triggered voltage shortage and starting issues
Symptoms owners cite: Trailer brake system warning light illuminates repeatedly; Continuous beeping alert; Dashboard warning flashes obscure speed display visibility; Warning message dismisses but immediately reappears; Radio system interference during alerts; Vehicle shutdown and voltage shortage (in one case); Starting difficulty (in one case); Occurs more frequently in rain or cold weather
Repairs/costs cited: One owner reports replacing controller module, plug adapter, and trailer brake switch with no resolution. No repairs confirmed in other narratives.
Recalls/TSBs owners mention: None documented; issue reported as 'widespread' and 'common' by multiple owners
Instrument cluster blackout and intermittent dash display failure
Instrument cluster goes completely blank during operation or at startup, rendering mileage and fuel gauge unviewable. Display failure occurs randomly and intermittently, persisting until vehicle is shut off. In one case, multiple safety features became inoperable simultaneously with instrument cluster blackout.
When: Random intermittent occurrence; one case at 5 MPH during operation
Symptoms owners cite: Instrument cluster goes completely black; Mileage unviewable; Fuel gauge unviewable; Dashboard display intermittently fails; Multiple safety features become inoperable simultaneously (one case); Audible alert accompanies loss of safety features (one case)
Repairs/costs cited: One case: dealer suspected wiring harness failure; vehicle not repaired. No other repair details provided.
Recalls/TSBs owners mention: Dealer suspected wiring harness failure; owner did not pursue repair. VIN not included in any recall per dealer statement.
Backup camera automatic maximum brightness at night
Backup camera automatically activates at maximum brightness when vehicle placed in reverse and cannot be dimmed or overridden. Brightness is severe enough to cause blindness and prevent visibility through any windows from inside the vehicle. Negates the safety benefit of the backup camera by making it impossible to see what is behind the vehicle.
When: Occurs every time vehicle is placed in reverse
Symptoms owners cite: Backup camera activates automatically at maximum brightness; Brightness cannot be dimmed; Brightness cannot be overridden by user; Blinding effect prevents visibility through vehicle windows at night; Interior of vehicle becomes dark relative to screen brightness; Rear visibility impossible without rolling down windows
Door lock system intermittent failure
Electric door lock system fails intermittently, with unlock button becoming non-functional when doors are locked. Failure occurs both when vehicle is stationary and while driving.
When: Intermittent, occurs both at rest and during operation
Symptoms owners cite: Unlock button fails to unlock doors; Failure occurs while vehicle is stationary; Failure occurs while vehicle is moving
Remote start system non-functional
Remote start feature does not operate despite prior service attempts. Vehicle can be started with physical key but not remotely.
When: Present at time of complaint; prior service attempts before ownership did not resolve issue
Symptoms owners cite: Remote start does not function; Vehicle can be started with physical key; Service messages regarding remote start appear on dashboard
Repairs/costs cited: Prior service attempt before current ownership failed to repair; service messages continue to appear
Recalls/TSBs owners mention: Dealership suspected remote start antenna as related to power loss issue
Random starting failure with clicking sound
Vehicle will not start on demand; turning over produces a click sound from electrical system rather than engine cranking.
When: Random occurrence
Symptoms owners cite: Vehicle will not start; Turning ignition produces clicking sound; No engine cranking
