Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain 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 provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
The 2014 Camaro powertrain cluster shows a pattern of dangerous stalls and loss of power at normal highway speeds—some with no warning, engine misfires, and multiple warning lights flooding the dashboard. One owner lost all power while exiting the interstate and couldn't restart for five minutes. Another experienced uncontrolled acceleration to 120+ mph when the throttle stuck to the floor, with heavy rust corroding the dash and throttle wiring.
Key refuses to eject from the ignition, sometimes requiring owners to slam the shifter into Park repeatedly before it releases. Shifters stick, won't engage Park, or get caught on key rings during turns, shifting the car to neutral unexpectedly. Manual transmission clutches stick to the floor or stay depressed after downshifting.
A brand-new 2014 with under 10 miles needed fuel injectors, pistons, and ultimately a complete engine replacement after 29 days at the dealership for compression issues. Another owner found metal debris in the engine oil from internal breakage. One transmission leaks three quarts every 30 days with no identified cause and no available rebuilds for the model.
A wiring short triggered simultaneous codes for transmission, stability control, traction control, ABS, and engine power—the car stalled repeatedly. Rust and corrosion appear throughout electrical systems, even on relatively low-mileage examples. Dealerships often cannot replicate failures or identify root causes, leaving owners with unresolved safety concerns.

Failure modes owners describe
Stalling and Loss of Power
Engine stalls or loses power while driving at normal speeds, sometimes with no warning. Vehicle may decelerate dangerously and shut down completely. Reports include stalling during turns, on expressways, and at highway speeds. Some owners report the car won't restart immediately or requires several minutes before restarting.
When: Occurs between 5,000 and 45,000 miles; one report at 27,300 miles
Symptoms owners cite: Engine stalls while driving; Loss of power while accelerating; Complete shutdown with no power to vehicle systems; Difficult restart or won't restart immediately; Engine misfire; Multiple warning lights (stability, traction control, engine power reduced, service stability and traction control)
Codes mentioned: Multiple codes reported (11 codes in one case; codes for transmission, stability control, traction control, ABS, engine power in another)
Repairs/costs cited: One case traced to short in wiring harness; one case required engine replacement after 29 days at dealership; technicians in other cases unable to duplicate failure or identify cause; one case dealership stated no recall available
Recalls/TSBs owners mention: GM denied buyback on one vehicle still under warranty; one dealership unable to duplicate failure; one owner filed complaint with GM/Chevy and lost case
Stuck Accelerator/Throttle
Gas pedal becomes stuck to the floor or unresponsive, trapping driver at high throttle. One documented case reached speeds over 120 mph before throttle released after 3–3.5 miles. Inspection revealed heavy rust in driver's dash area and under wiring.
When: At 27,300 miles; incident occurred at 60–65 mph on freeway
Symptoms owners cite: Gas pedal stuck to floor; Unable to release throttle despite stomping on pedal; Vehicle accelerates uncontrollably to 120+ mph; Heavy corrosion and rust on throttle system and dash wiring; Radio and driver-side seat motor also required replacement (possible water damage history)
Repairs/costs cited: No repair documented; four independent mechanics deemed vehicle undrivable and unsafe; rust and corrosion present in throttle and electrical systems
Engine Misfire and Metal Debris
Engine misfires and loses power; dealership identifies metal fragments broken off inside engine and found in oil. Occurs during city driving and causes loss of power.
When: Mileage at failure not specified
Symptoms owners cite: Engine knock; Loss of power while driving; Engine misfire; Metal debris in engine oil
Repairs/costs cited: Dealership diagnosed metal breakage in 6-cylinder engine; no repair details provided
Key Stuck in Ignition
Ignition key refuses to eject after engine is shut off. Occurs intermittently, sometimes more frequently on slight inclines but also on flat ground. Dealer workaround is to shift car back into Park and slam it multiple times until key releases.
When: Incidents reported but specific mileage not documented
Symptoms owners cite: Key won't come out of ignition after engine turned off; Occurs frequently, unpredictably; More common on slight inclines but happens on flat surfaces too; Requires repeated slamming of shifter into Park to release key
Repairs/costs cited: Dealership unable to replicate failure; one dealer suggested shifter replacement needed but vehicle not diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer made aware but no repair or recall issued
Shifter/Transmission Issues
Shifter sticks, won't move into Park, or becomes caught on key ring. Clutch on manual transmission models sticks to floor on downshifts or when reversing, or gets stuck depressed. One case reports transmission fluid leaking at 3 quarts per 30 days with no identifiable cause.
When: Reported at various mileages; transmission leak ongoing; clutch issue reported after initial use
Symptoms owners cite: Clutch sticks to floor and stays depressed; Shifter won't engage Park; Unable to remove key from ignition due to shifter malfunction; Shifter caught on key ring during turns, shifts car to neutral unexpectedly; Transmission fluid leak (3 quarts per 30 days); Sudden deceleration when shifter unintentionally shifts to neutral
Repairs/costs cited: Transmission shop unable to identify leak cause; stated new or rebuilt transmissions no longer available for this model; steering wheel height adjustment resolved one key ring catching issue
Recalls/TSBs owners mention: Dealer suggested shifter replacement in one case but repair not completed
Fuel System Defect (Early New Vehicle)
New 2014 Camaro with under 10 miles experienced repeated fuel system issues and compression problems. Dealership replaced fuel line, fuel injectors, and pistons without resolution, then attempted to even out cylinder compression. Finally required complete engine replacement after 29 days at dealership.
When: Within first 5,000–6,000 miles of ownership; purchased January 2014 brand new
Symptoms owners cite: Rapidly flashing check engine light (occurred twice); Fuel system malfunction; Compression leaking across cylinders; Engine performance issues
Repairs/costs cited: Dealership replaced fuel line, all fuel injectors, and pistons; attempted cylinder compression balancing; ultimately installed replacement engine; work took 29 days
Recalls/TSBs owners mention: GM denied buyback despite defect and safety concerns; warranty still in effect per manufacturer; case pursued with BBB and lawyer; dealership did not cooperate further
Electrical/Wiring Short
Short in wiring harness caused multiple cascading system failures including transmission codes, stability control, traction control, ABS, and engine power reduction messages. Vehicle stalled and had trouble restarting.
When: At approximately 5,000 miles
Symptoms owners cite: Multiple warning messages (Service Stability and Traction Control, Engine Power Reduced); Engine stall with difficulty restarting; Multiple codes triggering simultaneously for transmission, stability, traction, ABS, and engine power; Check engine light on and persistent
Codes mentioned: Approximately 11 codes reported from short in wiring
Repairs/costs cited: Dealership identified short in wiring harness and repaired it; vehicle returned to normal operation after repair
Fuse Box Corrosion
Fuse box area shows rust and corrosion. One case involved air conditioning going out due to rusted fuse box; moving the fuse temporarily restored function. Same vehicle later experienced stuck throttle with heavy dash and wiring corrosion.
When: At 27,300 miles; AC issue June 2018, throttle issue July 2018
Symptoms owners cite: Rust surrounding fuse box area; Air conditioning intermittent or non-functional; Heavy, deep rust under driver's dash; Widespread corrosion in electrical systems
Repairs/costs cited: AC temporarily restored by moving fuse; no permanent repair documented; throttle issue deemed undrivable by four mechanics
