“What are the reliability issues with the 2017 Corvette Z06?”
The 2017 Corvette Z06 is a 650-hp bargain, but it arrived with two headline quirks:
Track-day overheating / limp-mode. Early C7 Z06s (’15-’16) would spike coolant temps on road courses and cut power. GM issued revised hoods, super-charger covers, and a bleed procedure (TSB 17-NA-408) that largely solved the problem for ’17-and-later cars. If the previous owner performed the update, you’re good; if you plan to track it, still add an aftermarket radiator/oil-cooler and bleed the system religiously.
Recalls to watch: – Electric-power-steering assist failure (NHTSA 16V-209, later expanded to ’17 models). Symptom: sudden heavy steering. Dealer re-flash or column replacement fixes it. – Passenger-seat air-bag sensing (multi-model recall). Dealer re-calibrates the occupancy module.
Once those two recalls and the cooling TSB are closed, the LT4 drivetrain is stout. We see plenty of 40k-mile cars still on original super-chargers and torque converters. Keep up with 7,500-mile oil changes and the optional dry-sump system should last a long time.
Would you like me to surface some comparable low-mile Z06s, or help you arrange a pre-purchase inspection?
