The 2015 C7 Z06 with its supercharged LT4 is a track-capable monster, but early production years suffered catastrophic heat-related engine failures and transmission cooling issues that can sideline the car permanently if pushed hard.
Typical onset: Any mileage, especially under 30,000 mi with track use
Symptoms: Severe power loss and limp mode after 10-15 minutes of hard driving, Audible knock or pinging under boost at track temperatures, Check engine light with knock sensor codes, Coolant temps spiking above 260°F in performance driving
Fix: GM issued multiple TSBs and extended powertrain warranty to 10yr/120k for affected VINs. Worst cases require complete engine rebuild with updated pistons, rings, and calibration. Labor 30-50 hours for full teardown and rebuild.
Estimated cost: $15,000-25,000
8-Speed Automatic Transmission Fluid Overheating
Common · high severity
Typical onset: Any mileage with performance driving
Symptoms: Transmission temp warning on DIC during spirited driving, Harsh shifts or refusal to downshift when hot, Burnt ATF smell after track sessions, Limp mode activation during hard use
Fix: Factory transmission cooler is undersized for Z07 or track use. Aftermarket auxiliary cooler installation required (4-6 hours labor). Some cases need transmission oil cooler lines replaced if degraded. Cooler itself may leak at 40k-80k miles.
Estimated cost: $800-2,500
Cylinder Head Porosity / Coolant Intrusion
Occasional · high severity
Typical onset: 20,000-60,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Misfires on cylinders 1, 3, 5, or 7 (driver side), Milky oil or coolant contamination in crankcase
Fix: Porous casting in cylinder heads allows coolant seepage into cylinders. Requires head removal, inspection, and replacement if confirmed. Both heads typically done together. 18-24 hours labor plus machining.
Estimated cost: $6,000-9,000
Connecting Rod and Main Bearing Failure (High RPM Use)
Occasional · high severity
Typical onset: 30,000-70,000 mi with aggressive use
Symptoms: Rod knock at idle when engine is hot, Metallic rattling during acceleration, Oil pressure drops below 20 psi at idle, Metal shavings in oil during analysis
Fix: Sustained high-RPM use and heat cycling weakens bearings. Requires complete bottom end rebuild or short block replacement. Crank may need polishing or replacement. 35-45 hours labor.
Estimated cost: $12,000-18,000
Torque Tube and Transmission Mount Failure
Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Clunking from center tunnel during hard launches, Vibration at highway speeds (70+ mph), Driveline shudder during 1-2 or 2-3 shifts, Excessive rear-end movement under power
Fix: Rubber transmission mount deteriorates from heat and torque loads. Requires transmission support and exhaust removal for access. 4-6 hours labor. Some techs recommend upgrading to solid mounts.
Estimated cost: $600-1,200
Fuel Delivery System Failures (High-Performance Use)
Rare · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Lean fuel trims and hesitation under WOT, Fuel pump whine audible in cabin, Stumble or misfire above 5,500 RPM, P0087 fuel pressure too low code
Fix: Fuel filter screens can clog from debris, or high-pressure fuel pump can fail under sustained high demand. Filter replacement 1.5 hours, pump replacement 6-8 hours (tank drop required).
Estimated cost: $400-2,000
Owner tips
Change transmission fluid every 15k miles if tracking the car; factory 'lifetime' fill is inadequate for performance use
Install auxiliary transmission and differential coolers before any track days
Monitor oil analysis every 5k miles to catch bearing wear early
Let engine fully warm before boost over 50% and cool down after hard runs
Check VIN against GM's extended powertrain warranty campaign for early build dates
Buy a 2017+ model year instead—GM fixed most gremlins after 2016, or budget $5k-10k reserve for inevitable heat-related repairs on early cars.

Maintenance Schedule — 2015 Chevrolet Corvette C7 Z06
General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.

General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Corvette vehicles manufactured August 20, 2014, to August 27, 2014. In the event of a driver frontal air bag deployment, the driver air bag module back plate may fracture, allowing the driver air bag to separate from the steering wheel.
Consequence: An air bag that separates from the steering wheel may increase the risk of injury to the driver in the event of a crash.
Remedy: GM will notify owners, and dealers will replace the driver side air bag, free of charge. The recall began on October 29, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 14594.
PARKING BRAKE · 14V568000
2014-09-17
General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Corvette vehicles manufactured August 20, 2014, to September 4, 2014. In the affected vehicles, only one of the rear parking brake cables may be fully seated and engaged, resulting in the parking brake only operating on one of the rear park brake drums. Without the parking brake working on both rear wheels, the vehicle may roll away if parked on a steep gradient.
