Happened twice within a day. The main electric fan on the radiator stopped working and the car overheated. Once at idle, was able to shut the car off safely. The second time, there was traffic on the highway, and the fan stopped working and the car started to overheat. Had to shut the car off and wait for it to cool down on the side of the road. When I got the car home, I found the electrical connector of the fan to be melted and fused together. There was no indicator that the fan would stop running prior to the engine overheating.

I attended a two-day ncm track event at vir in june 2019. During the second session on day two my 2018 z06 had a power steering issue. Without any warning, I felt and heard a loud thump through the steering wheel as I approached turn 3 from no-name, I had very little steering ability that required heavy handed input on the steering wheel causing me to lift and brake to keep the car from running off the track. Then I received a dic message on the dash to 'service power steering gear.' I come in to let the car cool down and went back out later with no issues but was not running has hard as before. This power steering overheating issue is very concerning when on the track approaching a turn going 70 to 80 MPH. The outside temp was 90 degrees and the cooling system was running around 240 degrees. There is a gm preliminary information about reduction in steering assist while driving on the track during hot days. Bulletin no.: pi1535b date: nov-2017 that requires to install a new power steering gear cooling duct for 2014-2018 chevrolet corvette.

Two months ago, the car would crank, but not start. After several tries, and waiting overnight to continue trying, I had the car taken to the dealer. Tow driver drops car off flatbed, service writer gets in to cycle through to get mileage, etc, and the car starts. No error codes. They keep it for a few days, but no further problem. Ten days ago, same problem. Tow driver tries to start the car to drive off flatbed, without success. Dealer observes the problem, but, again, car starts for the service writer, and no codes. Leave it for several days, but no repeat of the prob. A few days ago, same problem, except now the car is 'on the verge' of starting, not just cranking, and I can smell fuel (this was not the case previously). The car was low on fuel when I left, and the low fuel warning had come on a few miles before I stopped. So, I get some gas in the car, eventually 1/2 a tank, and now the car is just cranking, not 'on the verge', and aaa is called to tow it. At this point, the attempts are taking their toll on the battery, but I continue trying, and, while the tow truck is en route, it starts just like always (push button, engine starts, no lag or hesitation). Dealer thinks it's fuel related, but doesn't know what the problem is, so has no idea what to do. Online forums suggest that it's an overheated fuel pump relay, or connectors thereto, resulting ultimately in a complete fuse box replacement.

Please see snip from http://corvettec7fiasco.blogspot.com/2016/02/thousands-of-2015-and-2016-chevrolet.html thousands of 2015 and 2016 chevrolet corvette c7 stingray and c7 z06 with defective 8l90 8-speed automatic transmission, with no help from general motors for the owners back in 2014, this blog predicted a variety of problems related to then upcoming 8l90 transmission, one of those sounding on paper ideas, as long as the execution delivers on the promises. So far, the variety of problems related to the new +general motors 8l90 eight speed automatic transmission was already mind boggling: from expected overheating issues, failing flex plates, variety of leaks and software related issues, all the way to right down scary cases of transmission voluntarily "inspiring" new corvettes to rev up and attempt to take off. However, what was missing were the problems with the torque converter. Apparently, this is no longer the case and in fact, the torque converted problems are well on the way to become another corvette issue of epidemic proportions, further eroding already weak faith the hardcore corvette buyers may have in +general motors and the ever popular +tadge juechter . As expected, the undersized and high spinning torque converter issues manifest themselves in a shudder and jerky motion the car starts demonstrating, accompanied by fluctuating engine rpms. However, here lies the big problem: the same symptoms can be easily associated with the ever popular afm forcing the newest corvette into 4 cylinder mode. There are 1000's of issues with these torque converters and who knows what accidents these failures have caused. My car is in the shop for 1 week for the repair, thank god it was covered by warranty.. There should be a total recall on these transmissions.. A search of the internet will fill you full of facts on these failures.

My corvette is a z06 that is designed and built for track use. When I use it on track it overheats and goes into limp mode after about 15 mins. Sometimes the power steer faults making it difficult and dangerous to control the car. I do not use it regularly on the street.

My 2007 corvette 2d convertible locks you in the car. You could get stuck in the car and suffocate to death. The windows and doors will not open, car is not recognizing the fob, you are totally stuck. Resort to emergency release on floor beside the seat. Lots of people don't know it's there! Like a passenger sitting in the car while you go to do an errand. They could "burn up" overheated and stuck! Gm knows that they have a problem as they sent me a letter advising me about the emergency release! But they refuse to fix it claiming they don't have a problem!. ...updated 02/23/16
