2015 CHEVROLET CAMARO

Typical onset: 60,000-100,000 mi

Symptoms: excessive oil consumption (1qt per 1,000 mi or worse), ticking/tapping from valve train at idle, check engine light with P0300-series misfire codes, rough idle or stumble on acceleration

Fix: AFM system creates lifter bore wear and collapsed lifters. Proper fix is AFM delete kit with new cam, lifters, pushrods, and tune (12-16 hours labor). Band-aid fix is lifter replacement without delete, which often fails again. Many engines need rings or full rebuilds if oil control rings are carboned up from long-term oil burning.

Estimated cost: $3,500-6,500 for AFM delete; $5,000-9,000 if engine needs rings or short-block

Typical onset: 70,000-120,000 mi

Symptoms: transmission fluid puddles under front of car, pink or red fluid stains on radiator support, low transmission fluid warnings, slipping or delayed shifts if fluid gets critically low

Fix: Factory quick-connect fittings on cooler lines crack or O-rings fail where lines meet the radiator-mounted cooler. Requires replacement of cooler lines and sometimes the cooler itself (3-5 hours labor). Access requires bumper removal.

Estimated cost: $600-1,200

Typical onset: 80,000-130,000 mi

Symptoms: gear oil leak at front of differential, whining or howling noise from front end that increases with speed, clunking on deceleration, vibration through chassis at highway speeds

Fix: Pinion seal leaks are common, but often the pinion bearing is worn too. Seal-only replacement is 2-3 hours, but if bearing noise is present, differential needs to come out for full pinion bearing replacement or rebuild (6-8 hours). Fluid contamination can damage ring-and-pinion if driven low on oil.

Estimated cost: $400-800 for seal; $1,500-2,500 for bearing replacement or rebuild

Typical onset: 60,000-100,000 mi

Symptoms: clunk or thud when shifting from park to drive or reverse, excessive vibration at idle in gear, banging noise over bumps from transmission tunnel, visible sag or tearing in rubber mount

Fix: Rear transmission mount deteriorates from heat and vibration, especially on V8 models. Requires lifting transmission slightly to replace mount (1.5-2.5 hours). Simple job but annoying symptoms.

Estimated cost: $250-450

Typical onset: 100,000-150,000 mi

Symptoms: hard starting when hot, loss of power under heavy acceleration, sputtering or hesitation at highway speeds, check engine light with lean codes (P0171/P0174)

Fix: In-tank fuel filter (part of pump module) clogs with sediment, especially if tank was ever run low repeatedly. Entire pump module replacement required, tank must be dropped (3-4 hours labor). Not a serviceable filter like older cars.

Estimated cost: $800-1,400

Symptoms: A/C blows warm after working fine, slow refrigerant leak (works for a few weeks after recharge, then quits), visible damage to condenser fins in front of radiator

Fix: Low front fascia and exposed condenser placement makes this car vulnerable to rock strikes. Condenser sits in front of radiator with minimal protection. Replacement requires full front-end disassembly and refrigerant recovery/recharge (4-6 hours).

Estimated cost: $900-1,500
