2022 CHEVROLET CAMARO

Typical onset: 15,000-60,000 mi

Symptoms: metallic ticking or tapping at idle that worsens when warm, check engine light with misfire codes, loss of power on acceleration, sudden catastrophic engine noise followed by no-start

Fix: AFM (Active Fuel Management) lifter collapse allows pushrods to drop, damaging camshaft lobes, rocker arms, and valves. Repair requires complete top-end teardown: lifters, camshaft, pushrods, rockers, often heads. Some cases damage pistons and require short-block work. 18-30 labor hours for comprehensive repair. AFM delete kit ($400-800) strongly recommended during rebuild.

Estimated cost: $4,500-9,500

Typical onset: 30,000-70,000 mi

Symptoms: harsh vibration during light acceleration between 25-45 mph, delayed engagement when shifting to drive or reverse, transmission slipping under load, check engine light with transmission codes

Fix: GM's 8-speed autos develop torque converter lockup clutch shudder and premature wear. TSB covers fluid changes with updated fluid, but many need torque converter replacement or full transmission rebuild. Transmission oil cooler lines also leak at crimped fittings. Cooler replacement: 2-3 hours. Torque converter: 8-12 hours. Full rebuild: 12-18 hours.

Estimated cost: $2,200-6,800

Typical onset: 40,000-80,000 mi

Symptoms: excessive clunking when shifting into gear, vibration through chassis during acceleration, visible separation or tearing of rubber mount, transmission sag visible from underneath

Fix: The rear transmission mount deteriorates from heat and torque stress, especially on V8 models with aggressive driving. Requires lift access and transmission support during replacement. 1.5-2.5 hours labor. Replace all mounts if one fails.

Estimated cost: $300-600

Typical onset: 50,000-90,000 mi

Symptoms: rough idle when cold, misfires under load, loss of power above 4000 rpm, increased oil consumption, check engine light with fuel trim codes

Fix: Direct injection causes carbon deposits on intake valves. PCV system clogs, increasing crankcase pressure and oil consumption. Walnut blasting intake valves: 4-6 hours. PCV valve and hoses: 1.5 hours. Catch can installation recommended to prevent recurrence.

Estimated cost: $600-1,200

Symptoms: long crank no-start condition, rough running and misfires across all cylinders, fuel pressure fluctuations, check engine light with fuel system codes, black debris visible in fuel filter

Fix: Internal deterioration of composite fuel lines releases rubber particulates that clog injectors and fuel pump. Requires complete fuel system flush, all fuel lines replaced with updated parts, new fuel pump module, new injectors. Filter is non-serviceable inside tank on these models. 12-18 hours labor for complete system replacement.

Estimated cost: $3,500-6,500

Typical onset: 80,000-120,000 mi

Symptoms: rattling noise from engine front on cold start, check engine light with timing correlation codes, rough idle, loss of power, engine runs but sounds like marbles in a can

Fix: The LGX timing chains stretch over time, causing cam/crank correlation faults. Requires front cover removal, both timing chains, guides, tensioners, and usually VVT phasers. Water pump replacement recommended during this job. 14-20 hours labor.

Estimated cost: $3,200-5,500
