The 2010 Camaro electrical issues cluster around water intrusion, power loss events, and sensor failures. Multiple owners describe complete electrical shutdown on highway, forcing emergency stops with no power steering. Stalling occurs without warning at speeds from 20 to 65 mph; some vehicles refuse to start intermittently despite good batteries. Water entering the instrument panel-to-body harness connector—particularly through sunroof leaks—corrodes the accelerator pedal position (APP) sensor wires, potentially triggering unintended acceleration.
Dealers frequently reset the ECU or replace modules without identifying root causes. In one case, an incorrectly installed wiring harness was discovered three replacements into an ignition module failure sequence. Air bag warning lights illuminate for sensor malfunction; one owner reported the passenger sensor entirely failed to detect occupants. Trunk latches stop working electrically, trunk lids spontaneously pop open on parked vehicles, and driver seats move on their own. License plate lights overheat and melt through plastic assemblies. One owner reports the ignition recall "repair" only attached a separate key with key rings without actually fixing the switch.
Owners struggled to get warranty coverage or manufacturer support. Several mention being told GM was aware of problems but unable or unwilling to resolve them, with vehicles parked due to safety concerns over multiple months at the dealership.
Failure modes owners describe
Water Intrusion & Accelerator Pedal Position (APP) Sensor Corrosion
Water enters the instrument panel-to-body harness connector carrying APP sensor signals, causing increased voltage on APP 1 and APP 2 circuits. This can trigger unintended throttle activation without driver input. The effect is more likely in vehicles exposed to salt spray or road salt, and increases with vehicle age. Water can bypass the reduced-power mode.
When: Occurs over time, particularly in vehicles exposed to salt or near salt water
Symptoms owners cite: Sudden unintended acceleration without driver input; Vehicle may not enter reduced power mode when APP voltage spikes; Can masquerade as brake switch malfunction in event data recorder (EDR) reports
Codes mentioned: APP 1 voltage increase, APP 2 voltage increase
Complete Power Loss While Driving
Vehicle experiences total electrical shutdown or loss of power on highway at cruising speed, forcing driver to pull over. Engine stalls without warning. Power steering becomes unavailable. Check engine light may illuminate briefly before stall. Dealership diagnostic attempts yield no codes or identified cause. Occurs multiple times over vehicle ownership.
When: Multiple instances reported between 20–65 mph, some occurring within first 1–2 months of purchase
Symptoms owners cite: Complete engine shutdown or stall without warning at highway speed; Loss of power steering; Check engine light illumination prior to or during stall; Vehicle restarts normally after shutdown; All indicator lights come on simultaneously
Codes mentioned: 5 error messages (unspecified), Check engine light
Repairs/costs cited: Dealership found no cause on first two visits; third visit reset computer; loose power cable under junction block near driver-side strut found in another case at 10,000 miles
Recalls/TSBs owners mention: GM acknowledged awareness of problem in at least one case but provided no assistance
Water Intrusion from Sunroof – Electrical System Failure
Water accumulation due to structural defect in sunroof sealing causes complete electrical system failure. Vehicle loses all power, eliminating power steering and door locks. Occurs while driving, creating immediate life-threatening situation with no ability to exit or steer.
When: At unknown mileage; repair cost $1,200
Symptoms owners cite: Complete loss of electrical power; No power steering; Door locks fail; unable to exit vehicle; Water visible in electrical system
