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.
This bulletin advises the dealers to maintain the vehicle stock on hand by doing a full inspection on the vehicles before being sold (prepping) to the customer.

full bulletin at NHTSA ↗Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

The failure pattern owners describe
Stalling without warning is the most serious complaint. Multiple owners report the engine cutting out completely while driving at highway speeds—sometimes multiple times within days—then restarting. Dealers struggle to diagnose this; one service department kept the car for two days but couldn't get a diagnostic code to appear, despite the stall happening before they connected the scanner. One owner at 10,249 miles had the issue four times before a dealer guessed at replacing the instrument cluster wiring harness.
Ignition switch problems are common at higher mileage. Keys get stuck and can't be removed; the ignition seizes and the vehicle won't shut off normally without pulling fuses or disconnecting the battery. One shop replaced the ignition lock cylinder for $518.74 and reported no shifter-to-ignition communication.
Cooling system failures appear early and repeat. At 3,180 miles, one owner's engine overheated with white smoke and burning smell. Others report hoses rupturing repeatedly, thermostat failures, and blown head gaskets—even in a car driven only 5 miles to work. The hood compartment gets dangerously hot.
Secondary electrical issues include poor acceleration and stuttering that worsens over time, brake lights going out, AC failure, an airbag warning light that won't go away, and—oddly—horn buttons so small drivers must look away from the road to find them.

Failure modes owners describe
Stalling and power loss while driving
Engine shuts down or loses power abruptly at highway and city speeds without warning. Vehicle can be restarted but failures recur intermittently. Dealer diagnostics unable to capture the fault or throw diagnostic codes, even when stalling occurs during service visits.
When: 3,180 to 82,000 miles; multiple occurrences reported before and after attempted repairs
Symptoms owners cite: Complete engine shutdown while driving; Loss of power and rapid deceleration; Engine stalls without warning; Check engine light may illuminate; Vehicle restarts after shutdown; Failures are intermittent and hard to reproduce
Codes mentioned: P0xxx (check engine light reported but specific codes not captured by dealers)
Repairs/costs cited: Dealers unable to diagnose; one attempted fix was wiring harness replacement in instrument cluster panel (unsuccessful long-term). Some owners suggested ignition switch and fuel pump as probable causes but not confirmed.
Ignition switch failure - key stuck in ignition
Key cannot be removed from ignition switch. Failure worsens over time (reported occurring over two-month period). Vehicle unable to shut off without removing fuse or battery disconnect.
When: 82,000 to 180,000 miles
Symptoms owners cite: Key stuck and cannot be removed from ignition; Ignition switch seized; Unable to turn vehicle off normally; No communication between ignition switch and shifter
Repairs/costs cited: Ignition lock cylinder replacement; one owner paid $518.74 for replacement. One vehicle not repaired at dealer.
Recalls/TSBs owners mention: Manufacturer was notified in at least one case but offered no assistance.
Overheating and cooling system failure
Engine overheating with white smoke from vents and burning smell. Cooling system hoses rupture and fail prematurely. Thermostat and head gasket failures reported. Hood compartment overheats severely.
When: Early in ownership; one reported at 3,180 miles
Symptoms owners cite: White smoke from air vents; Engine overheating; Burning smell from vents and engine compartment; Cooling system hoses burst; Hood extremely hot to touch; Sulfur odor through air vents; Brake pedal travels to floor (related to overheating)
Repairs/costs cited: Hoses replaced multiple times; thermostat changed; head gasket blown in at least one case. Recurring issue even after repairs.
Horn switch design - small and hard to locate
Horn button is only 1 inch by 1.25 inches on each side of steering wheel center. Buttons are small, hard to find, and not illuminated, requiring driver to look away from road to locate them, especially at night.
When: Constant issue from new vehicle
Symptoms owners cite: Small horn buttons difficult to locate while driving; Buttons not illuminated; Driver must take eyes off road to find horn
Poor acceleration and engine stuttering

When: Unspecified mileage
Symptoms owners cite: Struggles to accelerate; Unable to exceed 30-40 mph under full throttle; Engine shakes and stutters uncontrollably; Random stuttering while driving; Poor fuel economy; Issue worsens with time; Vehicle barely drivable
Brake light failure

When: Unspecified mileage
Symptoms owners cite: All brake lights inoperative
Air conditioning failure
AC system fails. Reported occurring around the same time as brake light failure.
When: Unspecified mileage
Symptoms owners cite: AC unit non-functional
