C7 Corvette Z06 Gets Extended Warranty Coverage Over On-Track Heating Issues

General Motors has implemented an extended warranty coverage for certain C7 Corvette Z06 models due to the sports car’s penchant to overheat while being driven hard on the track.
GM issued a document to dealers this week indicating it had implemented the new extended warranty coverage on 2015, 2016, 2017 and 2018 model year C7 Corvette Z06 models. The document says these vehicles “may have a condition where the vehicle may overheat and enter a reduced power mode when driven on a track at sustained high speeds in high ambient temperatures.”
The special coverage looks to address this issue and “covers the condition described above for a period of 7 years or 72,000 miles, which occurs first, from the date the vehicle was original placed in service, regardless of ownership.” The document also indicates that vehicle owners or lessees who paid for repairs referenced in this special coverage warranty are eligible for reimbursement.
To correct the overheating issue in affected vehicles, dealers are instructed to install an updated radiator package, along with updated shift point calibration software for automatic vehicles. These repairs will be made at no cost to the customer, although the customer must provide proof of the overheating problem in the way of a diagnostic code, photos or video.
The C7 Corvette Z06 overheating issues are well-known and widely publicized, as GM has already faced a number of class-action lawsuits over the problem. Chevy implemented some small changes on the 2017 model Corvette Z06 to help remedy the overheating issue, which included revised hood intake vents and a reworked cooling system, among more, but some owners still reported experiencing cooling issues with the vehicle.
The C7 Corvette Z06 is powered by a supercharged 6.2L LT4 V8 engine producing 650 horsepower and 650 pound-feet of torque, which is paired with a standard seven-speed manual or optional GM eight-speed automatic. These cooling issues have been experienced by owners of both automatic and manual transmission vehicles.

Maybe now GM will also address the cracking rim issue on the C7 Z06?
There’s a class action lawsuit regarding the wheels you can. Participate in
I would be really interested to know just what SPECIFIC modifications–mechanical AND tuning–they plan on making to mitigate the issue. Could be as simple as a higher temperature thermostat, in 2018s and 19s, and revising the shift points down in manual AND auto (paddle-shift) modes, as the temps rise, severely reducing performance, just not as severe as the present tune does. My guess is 2017s and earlier would get the 2018 radiator. There in no question in my mind that they will NOT install the ZR1 cooling packages (“cheek” radiator system) as it would cost GM a ton of money.
‘T’will be interesting.

I guess you didn’t read the article.
Oh but I did Michael!
A quote from the piece: “To correct the overheating issue in affected vehicles, dealers are instructed to install an updated radiator package, along with updated shift point calibration software for automatic vehicles.”

You just answered with your reply
Michael,
I think that you should learn how to read before you start sniping at people who write well-thought-out, detailed posts.

And the hits just keep on comin!
Yes the cracked rim issue affected me as well in my 2019 Z06. I had to buy a new rim on my own here in Germany. No warranty even it was not happening on the track. I never was on a race track with this car and still no warranty. That’s so cheap Chevrolet…
I feel bad for you when you need new wheels in the future go with aftermarket. There is a place in Florida that has the exact same looking wheels! That what I will be doing when mine go bad Generous Motors can go to hell!!
What is the name of the wheel place in Florida for the oem look alikes
Why wasn’t the 2019 ZO6 included in the extended warrenty for the overheating problem????
Didn’t affect 2019.
