I cannot believe the Corvette does not show that the alternator does not show that the car is not charging. I have a thirty year old corvette that will show you when the alternator does not show the car has an under performing alternator. If you do not have it showing on the display it will not show you that the alternator is defective. You have to show it on the display you never know you have a problem. It is an issue that is not a problem unless you know. I bought a battery and it was the alternator. They need to do a software upgrade to show you when a system goes out. My 1992 Corvette show you when there is a problem. Pathtic support on the part of General Motors.

At under 3000 miles car started sputtering sporadically and stopped driving while in motion. We were able to get the car home. Tried to start the car back up and it violently surged. Car had no idea what gear it was in. Transmission service now light came on and car sent me an email stating to take it to the dealership. Had car towed to dealer and used tow company they requested me to use.. Dealer says valve body flooded and replaced it. Still not working correctly and dealer says transmission is being flooded. Gm engineers not sure why. Car has been at dealer over a month and have no clue when it can be fixed. When you shifted from park to reverse car would lunge violently like you threw the transmission into park while the car was moving down the street. Car is not safe to drive as it just started to have issues during regular use. Dealer has confirmed and recreated the problem. I was told if valve body didnât fix it that gm would overnight a new transmission. Now I
At approximately 700 miles, my check engine light came on and the car produced an error message that said "Idle Creep Temporarily Disabled". Soon after that the car would lurch, buck on acceleration, and would only drive in even numbered gears. I felt the car was extremely dangerous and unpredictable to drive in this state since the car was unpredictably bucking and lurching forward and not shifting smoothly as usual. The dealer ran an OBDII poll and found five codes relating to transmission issues. GM has admitted to me that my vehicle is one of several that have "Assembly Debris" in the TREMEC supplied DCT. This "Assembly Debris" made the transmission filter completely black in appearance at 750 miles in addition to triggering the check engine light and dangerous driving behavior.
From mile 450 (approx.) forward,my CEL came on more than 5x. along with rear axel alert. In for service numerous times. Cleared codes, flushed solenoid. Replaced transmission/leaks. Actual service invoices are available.
