The 2012 Camaro SS with the LS3 is generally robust, but the 6L80 automatic transmission shows repeated cooling system failures, and higher-mileage examples suffer lifter/valvetrain issues that can spiral into catastrophic engine damage if oil change intervals are stretched.
Transmission Oil Cooler Line Failure (6L80 Auto)
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission fluid leaking at radiator connections or along cooler lines, Burnt transmission fluid smell, Harsh shifting or slipping due to low fluid level, Coolant contamination in trans fluid (milky appearance) if internal cooler ruptures
Fix: Replace both cooler lines and external cooler assembly if corroded. If internal radiator cooler failed, full transmission flush and filter service required, sometimes torque converter replacement if contaminated. 3-5 labor hours depending on contamination severity.
Estimated cost: $800-2,200
AFM (Active Fuel Management) Lifter Failure Leading to Engine Damage
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Ticking or tapping noise from valvetrain, especially on cold start, Check engine light with P0300-series misfire codes or P0521 oil pressure, Metal shavings in oil during changes, Sudden loss of power or catastrophic failure with rod knock
Fix: AFM lifters collapse due to oil starvation or internal wear. Requires heads-off repair to replace all lifters, often with AFM-delete components. If debris circulated, full teardown for rod/main bearing inspection and possible short block replacement. 18-35 labor hours depending on damage extent.
Estimated cost: $3,500-9,500
Transmission Mount Failure
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunk or thud during hard acceleration or deceleration, Excessive driveline vibration under load, Visible separation or cracking of rubber mount when inspected from underneath
Fix: Transmission mount tears from repeated high-torque launches and aggressive driving. Replace mount and inspect neighboring driveshaft carrier bearing for wear. 1.5-2 labor hours.
Estimated cost: $250-450
Fuel Pump Module Failure
Occasional · high severity
Typical onset: 90,000-140,000 mi
Symptoms: Hard starting or extended crank time, especially when hot, Stalling or stumbling during acceleration, Fuel pressure drops below spec (should be ~58 psi), Check engine light with lean fuel codes (P0171/P0174)
Fix: Fuel pump wears out or level sender fails. Tank drop required to replace entire pump module assembly. 2.5-3 labor hours.
Estimated cost: $650-1,100
PCV System Failure and Excessive Oil Consumption
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Oil consumption exceeding 1 quart per 1,500 miles, Smoke from tailpipe on deceleration or startup, Fouled spark plugs, Oil in intake manifold or throttle body
Fix: PCV valve and hoses crack or clog, causing crankcase pressure that forces oil past rings. Replace PCV valve, hoses, and clean intake system. If piston ring damage occurred, cylinder head removal and ring replacement required. Basic PCV fix: 1.5 hours; with rings: 20+ hours.
Estimated cost: $200-500 (PCV only), $4,000-7,000 (with ring job)
Head Gasket Seepage (Coolant External Leak)
Rare · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Visible coolant weeping at head/block mating surface on sides of engine, Slight coolant smell after engine heat cycles, Gradual coolant loss without obvious external leaks elsewhere, No overheating or combustion gas in coolant (not blown gasket)
Fix: LS3 aluminum heads can develop minor seepage at gasket interface from repeated heat cycling. Full head gasket replacement requires removal of both heads, surface inspection, and ARP stud upgrade recommended. 14-18 labor hours.
Estimated cost: $2,800-4,200
Owner tips
Change oil every 5,000 miles maximum with quality synthetic (0W-40 or 5W-30) to preserve AFM lifters—extended intervals are a death sentence for these engines
If buying used, pull valve covers and inspect for sludge or metal debris; walk away if present
Consider AFM-delete tune and hardware at first sign of lifter noise to avoid $8k+ engine rebuild
Inspect transmission cooler lines annually for corrosion; preemptive replacement at 80k saves the transmission
Avoid extended idling or short trips in V4 mode—keep it in V8 mode for engine longevity
Buy one if maintenance records show religious oil changes and no deferred repairs—skip it if the AFM lifter tick is present or history is unknown; the LS3 is bulletproof until it isn't, and that repair costs more than the car's value.

General Motors LLC (GM) is recalling certain replacement flip-key ignition transmitter assemblies sold as replacement equipment for 2010-2015 Chevrolet Camaro vehicles. GM dealers may have inadvertently sold these assemblies as replacement keys despite them having been recalled under NHTSA recall number 14V-346 (GM number 14294) when they were the original equipment assemblies. The driver may accidentally bump the ignition key with their knee, moving the ignition out of the run position and turning off the engine.
Consequence: Once the engine is off, the vehicle can lose power steering and power braking, increasing the risk of a crash. The air bags may not deploy in a crash, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will inspect and, as necessary, replace the key with the flat blade design, free of charge. Interim notices informing owners of the safety risk were mailed November 6, 2019. Owners received a second notice and the recall began February 4, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N192223230.
SEATS:FRONT ASSEMBLY:POWER ADJUST · 14V447000
2014-07-23
General Motors LLC (GM) is recalling certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position.
Consequence: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the height adjuster shoulder bolts, free of charge. The manufacturer distributed interim letters to owners on September 11, 2014. The recall began on December 26, 2014. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14271.
ELECTRICAL SYSTEM:IGNITION · 14V346000
2014-06-20
General Motors LLC (GM) is recalling all 2010-2014 Chevrolet Camaro vehicles manufactured December 3, 2008 to May 23, 2014. In the affected vehicles, the driver may accidentally hit the ignition key with their knee, unintentionally knocking the key out of the run position, turning off the engine.
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position could cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will remove the key blade from the original flip key/RKE transmitter assemblies, and provide two new keys and two key rings per key. The recall began August 25, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 14294. Note: Until the recall has been performed, it is very important that drivers adjust their seat and steering column to allow clearance between their knee and the ignition key.
AIR BAGS · 14V300000
2014-06-06 · RQ13002
General Motors LLC (GM) is recalling certain model year 2012 Buick Verano vehicles manufactured December 2, 2011 to July, 16, 2012, Chevrolet Cruze vehicles manufactured December 7, 2011 to July 25, 2012, Chevrolet Sonic vehicles manufactured December 5, 2011 to August 2, 2012, and Chevrolet Camaro vehicles manufactured December 1, 2011 to June 11, 2012. The driver side frontal air bag has a shorting bar which may intermittently contact the air bag terminals.
Consequence: If the bar and terminals are contacting each other at the time of a crash necessitating deployment of the driver's frontal air bag, that air bag will not deploy, increasing the driver's risk of injury.
Remedy: GM will notify owners, and dealers will replace the steering wheel air bag coil, free of charge. The recall began on July 25, 2014. Chevrolet owners may contact GM at 1-800-222-1020. Buick owners may contact GM at 1-800-521-7300. Note: This is an expansion of recalls 12V-522 and 13V-023.
