Electrical gremlins plague the 2015 Camaro across multiple systems. The most critical issue: the ignition key gets stuck in the Park position or won't turn all the way to OFF, requiring owners to cycle the transmission repeatedly or wait minutes to over an hour for release. Some owners report the engine shutting off completely while driving at highway speeds—a total power loss that kills power steering and braking. One owner crashed into a snowbank when the flip-key fob unexpectedly shut off the engine during winter driving, racking up $8,000 damage.
The radio/infotainment module cuts out intermittently, emitting loud popping sounds, and when it fails, so do turn signal chimes, seat belt warnings, and hazard lights—safety features that depend on that same module. One owner found a YouTube workaround (cutting a white wire) that restores the radio but disables hazard lights.
Owners also report battery drain from starter failure, water damage from a detached sunroof hose corroding the electrical wiring, shift-interlock problems preventing key removal, and climate control actuators that cost over $4,000 to fix because the dashboard and windshield must be removed. Dealerships often charge $99–$400 for diagnostics without finding a solution. GM cites an expired recall (19E064000) and denies warranty coverage despite the widespread nature of these complaints.
Failure modes owners describe
Key stuck in ignition / difficult key removal
The ignition key becomes stuck or difficult to remove after placing the vehicle in Park. The key sometimes stops at the ACC (accessory) position and won't turn fully to the OFF position for removal. Owners report having to repeatedly cycle the transmission in and out of Park, restart the engine multiple times, or wait several minutes to an hour for the key to release. One owner disconnected a plug under the steering column as a workaround after watching a YouTube video.
When: Typically occurs when parking the vehicle; reported from early ownership (~1-2 years in service) through higher mileage (104K miles). One report at 20K miles on a brand-new vehicle.
Symptoms owners cite: Key won't turn fully to OFF position to come out of ignition; Key stuck at ACC (accessory) position; Requires multiple restarts or gear cycling to release key; Delay of minutes to an hour before key releases; No warning lights illuminated during event
Repairs/costs cited: Dealership diagnostics ranged from $99–$400 without resolution. One dealer quoted $500+ for shifter replacement, which GM warranty did not cover. Some owners used YouTube workaround (disconnecting yellow relay box plug under steering wheel), though long-term safety of that fix unknown. One owner at 104K miles was told recall (NHTSA Campaign 19E064000) had expired.
Recalls/TSBs owners mention: NHTSA Campaign Number 19E064000 (Electrical System) was issued but has an expiration deadline; some owners were told the recall deadline passed (April 2021). GM declined warranty coverage in multiple cases despite 3-year/36K warranties.
Flip-key fob ignition failure – engine stall while driving
The flip-key ignition fails while the vehicle is in motion, causing the engine to shut off completely. This loss of power also disables power steering and braking, creating a serious safety hazard. One owner's key flicked off during winter driving, causing the vehicle to lose control and crash into a snowbank with $8,000 damage. Another owner's knee accidentally bumped the key into the OFF position while driving.
When: One crash reported February 28, 2019, at unspecified speed. Other stalls reported at 8 PM at 30 mph, during highway driving, at 35 mph, and at 40 mph. One incident occurred 55 miles into a rental car's delivery.
Symptoms owners cite: Engine and all electrical power lost while driving; Loss of power steering and power braking; Vehicle coasted to stop or went out of control; No warning lights before failure; Key accidentally bumped into OFF position by driver's knee
Repairs/costs cited: One owner incurred $8,000 in front-end collision damage after crashing into a snowbank. Multiple repair attempts at dealerships; clear coat peeling off repaired panels. Vehicle deemed unsafe to continue using.
Recalls/TSBs owners mention: One owner was informed that a recall for the flip-key fob had been issued and there was a lawsuit, with a deadline of April 2021. Owners cited NHTSA recall reference N192223230 for flip-key ignition failures. Some owners received new standard keys in place of the flip-key, but defect persisted in other owners' vehicles.
Radio/infotainment module intermittent failure with safety feature loss
The radio/infotainment system cuts out intermittently, often accompanied by a loud popping or static sound through the speakers. When the radio module fails, critical safety features tied to the system—including turn signal audible alerts, seat belt warning chimes, and hazard light indicators—cease to function. The radio comes back on after battery disconnection or resets, but the problem recurs. One owner noted YouTube videos show owners cutting a white wire to restore radio function, but this disables hazard lights.
When: Failures reported from approximately 30K to 93K miles. One owner at 45K miles noted increasing frequency.
Symptoms owners cite: Radio cuts out intermittently; Loud popping or crackling sound through speakers before cutout; Turn signal audio alert fails; Seat belt warning chime absent; Hazard light indicators inoperable when radio is out; Dashboard/instrument panel lights flicker or turn off; A/C or defroster stops working when radio fails; Failure triggered by brake pedal, clutch pedal, or turn signal activation; Failure can occur randomly while stationary or driving
Repairs/costs cited: Battery disconnection for a few minutes restarts the module temporarily. One owner watched YouTube video showing white wire cut under dashboard; this restored radio but disabled hazard lights. Dealerships either found no fault or recommended replacing entire radio/stereo system and dash kit at high cost. One dealer charged $300 for diagnostics and found nothing.
Recalls/TSBs owners mention: Manufacturer stated awareness of similar failures but offered no further assistance in multiple cases. GM declined to order parts or authorize repairs without the owner paying diagnostic fees first.
Complete electrical system power loss while driving
The entire electrical system fails suddenly while the vehicle is in motion, cutting off the engine, headlights, power steering, and power brakes. The vehicle becomes completely uncontrollable until it coasts to a stop. This has occurred multiple times in some vehicles and is believed to be related to the ignition switch or electrical module.
When: One incident reported February 3, 2017, at 30 mph during evening drive. One incident at 35 mph on highway. One incident 30 minutes into 55-mile rental car trip. One incident while exiting freeway on 30-degree incline.
Symptoms owners cite: Engine shuts off completely; Headlights cut off; Power steering lost; Power brakes lost; Dashboard goes completely blank; Vehicle stalls without warning; No warning lights before event
Repairs/costs cited: Vehicles restarted successfully after pulling over. One rental car owner noted the vehicle should not have been in the rental fleet without proper recall service. One owner suspects knee contact with ignition area but cannot fully explain the cause.
Recalls/TSBs owners mention: GM recalled 500K 2010–2014 Camaros for ignition-switch defect, but 2015 models appear not to be included in that recall despite reporting identical symptoms.
Sunroof hose detachment causing electrical corrosion and vehicle shutdown
A sunroof drainage hose detaches from its connection in the trunk, allowing water to leak into the vehicle's wiring harness and corrode the electrical system. This water damage caused the entire vehicle to shut off without warning while driving on a highway. The defect was pre-existing but not disclosed at the CPO (Certified Pre-Owned) purchase. Owners were told the hose can detach again after repair, presenting an ongoing safety risk.
When: Vehicle purchased as CPO with 29,883 miles; failure occurred before 34,000 miles, just over 4,000 miles of ownership.
Symptoms owners cite: Large water leak from sunroof drainage hose in trunk; Visible corrosion of wiring harness; Vehicle shuts off without warning while driving on highway; Complete loss of electrical system function
Repairs/costs cited: Dealership diagnosed large water leak from detached hose as cause of electrical system damage. Repair cost not stated but would be substantial due to extent of corrosion.
Recalls/TSBs owners mention: No recall identified for this design defect. Dealership noted that once repaired, the hose could detach again without the owner's knowledge, creating recurring electrical hazards.
Starter failure with battery drain
The starter motor fails and drains the battery overnight without any warning indicator. The battery was replaced, but testing showed the starter was not responding at all. The owner suspects the failure is related to the ignition switch malfunction and fears the vehicle could stall without warning while driving.
When: Reported at 46,254 miles. Owner purchased vehicle new, so failure within first few years.
Symptoms owners cite: Battery goes completely dead overnight; No warning lights or battery indicator before failure; Starter motor gives no electrical response; Key stuck in ignition (noted as separate but related symptom)
Repairs/costs cited: Battery and alternator tested good at AutoZone. Starter replacement required. At 46K miles, starter failure is well below typical 100K–150K mile lifespan.
Recalls/TSBs owners mention: Dealership told owner ignition switch malfunction could not be related to starter failure, which the owner disputes.
Engine Control Module (ECM) failure and burnout
The engine control module burns out while the vehicle is being driven, causing the engine to stall, the steering wheel to seize, a jerking motion, and the engine warning light to illuminate.
When: Reported at approximately 6,000 miles on a new vehicle.
Symptoms owners cite: Vehicle jerks while driving at 35 mph; Steering wheel seizes; Engine stalls; Engine warning indicator illuminates
Repairs/costs cited: ECM was replaced at dealership.
Recalls/TSBs owners mention: Manufacturer was notified of the failure.
Climate control actuator failure requiring dashboard removal
The heat actuator in the climate control system fails, requiring replacement. Due to the vehicle's design, the actuator cannot be accessed without removing the dashboard and windshield, making the repair extremely labor-intensive and costly. The defect appears to be premature wear of flimsy internal parts with no preventive maintenance possible.
When: Reported at 2 years of ownership. Another A/C complaint noted the defrost blowing warm air on one side and cold on the other, causing windshield fogging.
Symptoms owners cite: A/C or heat stops blowing adequate air; Defroster blows warm air on one side, cold air on the other; Windshield fogging severely; Defrost unable to clear windshield effectively
Repairs/costs cited: One dealership quoted $200–$300 for heat actuator replacement due to labor required to remove dashboard and windshield. Another complaint noted A/C box repair would cost over $4,000 because the box cannot be serviced without full dash removal and windshield removal. Parts are described as flimsy and prone to failure; no repair can prevent recurrence.
Recalls/TSBs owners mention: No recalls or TSBs identified in complaints.
Shift interlock and ignition interlocking defect
The automatic transmission shifter is electrically interlocked with the ignition, but the connection is faulty. The shifter must be pushed forward to feel a click before the key will release from the ignition, but this workaround is temporary and the key eventually becomes stuck again. Some owners report the shifter needs replacement.
When: Issues began early in ownership and worsened over time. Reported at various mileages including 38K, 40K, and higher.
Symptoms owners cite: Key won't release from ignition unless shifter is pushed forward with a click; Workaround becomes less reliable over time; Key becomes stuck again after initial fix; Shifter may need full replacement (reported cost ~$500)
Repairs/costs cited: One dealer recognized the issue and showed owner the shifter click workaround. Multiple owners report needing shifter replacement, which GM warranty has not covered.
Recalls/TSBs owners mention: One dealer said the vehicle was not included in electrical system recalls (Campaign 19E064000).
Instrument panel and lighting system intermittent failure
The instrument panel lights, dashboard displays, and turn signal/hazard lights flicker or fail intermittently while driving. Hazard lights and turn signals may malfunction independently, and when the driver attempts to operate them, they fail to work. This creates a safety hazard as other drivers cannot see the vehicle's intended direction or emergency status.
When: Reported at approximately 72K miles and higher.
Symptoms owners cite: Instrument panel lights flicker intermittently; Dashboard display lights go on and off; Hazard lights malfunction or fail to operate; Turn signal lights fail to operate as designed; Failure occurs while driving at various speeds
Repairs/costs cited: No repairs completed in reported cases.
Recalls/TSBs owners mention: Manufacturer notified and provided case numbers but no further assistance.
