Early C7 Z06 models, particularly 2015 and 2016, were known to suffer from engine overheating and heat soak during extended high-performance driving — especially on road courses or hot days. This was largely due to insufficient radiator and intercooler capacity paired with the heat generated by the LT4’s supercharger. Symptoms included: Engine derating or going into limp mode during track sessions Supercharger temps exceeding safe operating limits Poor thermal management when driving aggressively The issue was widely discussed in forums, track day communities, and even by professional reviewers. GM made cooling improvements in the 2017+ model years, including: Larger supercharger heat exchangers Improved radiator fans Better airflow management through the front grille 1. Supercharger Rattle and Failure Some owners reported a metallic rattle or chirping noise coming from the LT4 supercharger, especially at idle or low RPMs. This was due to isolation coupling wear inside the Eaton blower unit. GM addressed this in a TSB (Technical Service Bulletin) and updated the design in later years. Superchargers were replaced under warranty if diagnosed correctly. 2. Manual Transmission Problems A small number of 7-speed manual Z06s experienced: Grinding when shifting gears, especially from 2nd to 3rd Syncro issues and notchy engagement This was more commonly reported in 2015–2016 models. Some were resolved with fluid changes, while others required transmission service or replacement under warranty. 3. Carbon Ceramic Brake Concerns (Z07 Package) While the Brembo carbon ceramic brakes offer incredible stopping power, there were reports of: Squeaking or squealing at low speeds Premature rotor wear if used aggressively on track without proper warm-up/cool-down cycles High replacement cost if out of warranty These aren’t necessarily defects but are part of the trade-off for high-performance hardware. 4. Interior Wear and Build Quality Some owners noted: Premature wear on leather seats and trim (especially on bolsters and steering wheels) Creaks and rattles from trim pieces, particularly in earlier years (2015–2016) Infotainment system glitches or screen freezing (MyLink system) GM issued software updates to address infotainment bugs. 5. Wheel Cracking A limited number of owners reported cracked wheels, especially the factory wheels on Z06s with the Z07 package and Cup 2 tires. GM typically did not cover these under warranty unless a defect was clearly identified.

What years did the C7 Z06 have cooling issues?
The 2015 and early 2016 Z06 models had known cooling issues under high-performance driving due to undersized radiators and heat exchangers. GM made significant improvements starting with the 2017 model year. Did GM offer a special warranty for cooling issues?
Yes, GM offered an extended warranty for certain 2015–2018 Z06 models, covering cooling system components for up to 7 years or 72,000 miles. This was in response to owner complaints and a class-action lawsuit. Does the C7 Z06 have Apple CarPlay?
Yes, starting in 2016, the C7 Z06 came with Apple CarPlay, but only with a wired USB connection. Wireless Apple CarPlay was not available until the C8 generation (2021+). What’s the difference between 2015 and 2019 Z06 models?
The 2015 Z06 was the first model year and had known cooling issues and supercharger noise. By 2019, the Z06 was refined with improved cooling, fewer complaints, and higher reliability. No major engine or transmission changes occurred, but build quality and track performance improved. What is the Z07 Performance Package?
The Z07 Performance Package includes Brembo carbon ceramic brakes, Michelin Pilot Sport Cup 2 tires, aerodynamic enhancements, and FE7 suspension tuning. It's designed for maximum track performance. Return to the home page from C7 Corvette Z06 Specs
