Normal driving conditions while in Z-mode in moderate traffic, an audible bang was heard, however there was no immediate issue. A few minutes later the Check Engine Light, ABS, Traction Control and other lights appear on dash. Once lights appear, brakes fail and no longer slow the car down, the gas pedal only revved the car and could no longer accelerate. The car was still on and “driving”, I just didn’t have acceleration or brakes. I put my turn signal on and eventually was able to safely pull off the road and stop the vehicle utilizing Neutral and the Emergency Parking Brake. I was in genuine fear of crashing due to not having brakes or acceleration and felt that if the parking brake and/or neutral failed, then I’d have to crash to stop the vehicle. Not having brakes or acceleration put myself, my passenger, and every vehicle around me when it occurred at risk of injury. This has occurred twice in less than 1 year of ownership with this vehicle and I’ve taken it to two dealerships, Mike Reichenbach Chevrolet and Rick Hendrick Chevrolet. When it first occurred in December 2023, I was also in Z-Mode in light traffic, after it occurred, I drove slowly to the dealership with the hazard lights on. The second time I brought it to a dealership was after the first dealership couldn’t find the cause nor replicate the issue. The codes were cleared by the first dealership, but the car was still operating roughly and not as designed. The third time, in July 2024, it was brought to Rick Hendrick Chevrolet where the service invoice says “GOOD POSSIBILITY THE AFTERMARKET GPS UNIT PLUGGED INTO THE DLC PORT IS SHORTING OUT THE VEHICLE COMMUNICATION CIRCUITS AND CAUSING INTERMITTENT ELECTRICAL ISSUES. MAY BE ALSO CAUSING BATTERY DRAIN ISSUE.” The device referred to is called Bouncie, I got it AFTER this first occurred and the service team there is blaming both of these occurrences on the device. No repair was performed as the issue couldn’t be replicated.

2005 Corvette coupe, manual trans, Z51. Intermittent problem: Electronic steering column will not unlock when attempting to start or will not lock on shutdown. Vehicle inoperable, sometimes in potentially hazardous situations e.g., late night in parking lot, and compromised anti-theft feature. Possibly relevant: When parked but steering failed to lock, continuous battery draw is 4 amps, which might contribute to the "dead battery syndrome" that 2005 M6 Corvettes are known for. Hard to separate the two issues since either way the starter will not engage. Problem has existed since new (2005) but has gotten progressively worse. GM nonresponsive to multiple owner complaints. Aftermarket "Column Lock Bypass" work-arounds have been sold for this problem, but they are potentially dangerous since they simply spoof the BCM into thinking that the lock is fully released when it is simply unpowered and can easily move into a partially locked position with vibration and time. This is what I recently observed that motivated this safety complaint. GM finally issued a recall in 2018 (13 years after MY) for this problem, but for some reason did not include manual transmission cars in the recall, possible because production was small compared with automatics. But from internet forums, it is clear that this problem affects all 2005 M6 Corvettes.

Vehicle has open recall 09v491 for roof panel separation. The roof on the vehicle has separated and come apart in pieces leaving the front seal exposed. Gengras Chevrolet in Ct has ordered and received the replacement panel which has now been sitting at their dealership for approximately 2.5 weeks because they refuse to send it to paint until they rectify the outdated paint supply reimbursement cost with GM. In the meantime I have not had a spot for the vehicle inside and if I dont know its going to rain or dont get the car inside somewhere in time the water leaks down the windshield post and into the body control module. Currently the car drains the battery, gauges intermittently do not work as well as the power windows, starter button etc. from a recent pop up storm. Ive been back and forth with the dealer and spoke to a GM rep, niehter of which have proven useful in the situation. I just keep getting pushed off and told that I have to wait for them to figure it out with GM, even though it could potentially take 2 or more weeks to paint the top once the body shop actually gets it. This whole process has started approximately August 1st.

It has been reported numerous times of the excessive battery drainage of these vehicles. Gm decided that the car would need to be placed in reverse with the parking brake engaged for the car to be totally turned off. This causes the battery to drain excessively, I have replaced 4 batteries in a year. You will be stranded wherever you're at. Gm has not tried to resolve this matter. What they did was in 2006 took the function off the car, so they wouldn't have to deal with it. This needs to be resolved by gm, or does it take a dead battery, a jump ,and a half charged car to shut down in the middle of the road causing an accident.
