For last 3 years whenever I fill my vehicle with gas the garage smells of gas until the tank is less than half a tank... The other major issue is the vehicle will not come out of park multiple time. This has put me in embarrassing situations many times. I stay away from driving the vehicle so many times when I could be in physical danger.

This particular Corvette C6 model (2005 through 2013 model years) has a well known and documented problem with the automatic transmissions. Upon engine startup, it oftentimes will not shift out of the Park gear. When the Chevrolet Customer Service people were called about this, their response was that they are well aware of this problem with the C6 model years. The Customer Service people said that a Recall was not issued because the way to address this problem is to: Shut off the engine, put the ignition in the Accessory mode, then try and shift the transmission into Neutral. If it is able to shift into Neutral, then start the engine. Once the engine starts, then try and shift the transmission into the Drive or Reverse gear. If this sequence doesn't work, we were told just to keep repeating this sequence over and over. There have been occasions when we had to repeat this sequence at least half a dozen times and there have also been occasions where we were stranded in parking lots and had to leave the car and come back to it later to try again. This is a safety concern due to the real possibility of being stranded at night in parking lots. There aren't any warning lights or messages. There also aren't any advanced warnings, in terms of symptoms. The only way the problem manifests itself, is when the car cannot be shifted out of the Park gear. Whenever the car is brought into service, including at Chevrolet dealers for such items as oil changes, the mechanics try shifting it out of the Park gear and when they can't, they will call and ask us what to do. The added concern here is that if the mechanic physically forces the shifter out of the Park gear, the entire shifter and possibly the transmission will be damaged. We are the original owners of the car and it only has 18,000 miles on it. This problem first appeared about two years ago but it is happening much more often now.

Vehicle will not shift out of park after starting, even when brake pedal is properly depressed.

After starting the vehicle I am unable to shift out of park. This endangers both myself and a passenger if I need to move the car quickly in case of fire or another vehicle or object coming toward me. It also endangers other passengers in vehicles I may be blocking because they are unable to move. There are many other C6 Corvettes with this same problem documented per the Corvette Forum and YouTube.

Car sticks in park at times and is hard to get out of park, happens often for past year

While driving the clutch pedal went to the floor and my standard 2007 Corvette could not be shifted. Car was flat-bedded to dealer as car was not drivable. I could have been killed in heavy freeway traffic. My vehicle had 8656 miles approx. Apparently GM issued service bulletins on this problem, redesigned the clutch master cylinder and issued an extended warranty for 10 years or 100,000 miles there was no recall. GM was to have noticed all owners of this problem but did not in my case. When I called GM they said that they were sorry but would not indemnify me for the $2,912.18 cost to replace the master and slave clutch cylinders. In my case I was in a parking lot in motion. So luckily I am still breathing.

I purchased the vehicle a few months after tsb N150682 was issued. It could be dangerous with the leaky fuel and smell.

Driving down the highway and a big black cloud of smoke starting spewing out so I pulled over. Had it towed to a Corvette specialist and they informed me that piston #7 was cracked. I still have the cracked piston in my possession, I've attached photos.

Automatic shifter will lock in park and will lock and not move. Car can be running, in park, and it is impossible to move the shifter. Restarting or using accessory mode will sometimes unlock. Often you are just stuck and car must be towed

I was driving down my street ready to downshift my clutch as I prepared to enter my driveway. I lost control of my clutch as the pedal went to the floor and did not return. I almost lost control of my vehicle since I was not sure in that split moment on how to slow down my vehicle as I was preparing to enter my driveway. I immediately had to hit my brake pedal very hard to slow down my vehicle and came to a stop inches from hitting my home. I only wonder if I had been traveling on the highway or at some high rate of speed, what would have happened to my vehicle if could not engage my clutch and drive my vehicle. Since my powertrain became inoperable, I felt like I had no control of the vehicle. This is a dangerous condition and GM should have recalled the vehicle. GM is very aware that the clutch could fail. They sent me a letter 4 years ago (copy attached) telling me they found an internal failure in the master clutch cylinder. But GM would not replace the clutch. That is dangerous situation to be driving and not sure when your you could lose control of your vehicle. I am lucky to be alive and unharmed today despite GM's failure to replace this defective clutch.

Vehicle is always stationary when it gets stuck in park, and unable to shift into gear. I let it set for a few minutes then push start again. Sometimes it will shift into gear and other times it will not. 50/50 chance one way or the other. This has happened several times since I inherited this vehicle from my father in early 2017 with 48,000 miles on it. Fast forward to today 03/09/2018 vehicle does not go into park but is "stuck" in neutral, does not go into park or any other gear.

Shifter of auto. Trans. Sticks in park. This is dangerous if your stuck in traffic, emergency vehicle is being blocked, or at railray crossing with train coming, or trying to get away from a forest fire. Over 3000 hits on you-tube for this problem with 2006 and 2007 Corvettes and maybe others. Chevrolet will not fix problem. Only 14,000 miles on my car!!! car is stationary in park, and won't move!!!

October of this year. My transmission in my Corvette would not go into park. I put it into reverse and backed it out and then could not put it up into park. I then put it into drive and moved forward some and tried to put it into park. This time it would not go even into reverse. The vehicle has 56220 miles on it. I stays in a garage climate controlled and has seen bad weather maybe 6 time (snow or rain). So off the car went to the Chevrolet dealer to get repaired. I googled the problem to do a little research and found out that there has been lots of complaints on this same problem with out any results. So there is a plastic piece in the shiftier mechanism the entire assembly must be replaced. So at $1068 later the problem was fixed. Did GM know about the problem, they sure did. The service person told me he has replaced 2 the same week and more through the year. My gut feeling is that this is a hazard to not only the owner but to other drivers out there. I even feel that it could be life threatening to everyone. The piece gets stuck in the unit and one could drive straight into a wall or run over someone in the vehicles path.

Transmission is locked in neutral or drive and cannot shut off engine or place car in reverse or park. Had to disconnect the battery to shut off the engine. Once off, the engine could not be restarted and had to manually push the vehicle to get it off the street. This is a major safety issue--fortunately I was not on a railroad tracks when this happened!

After taking shift handle out of park will not engage in any gear

- Venice, FL, USA

On several occasions the vehicle would not shift out of park. It is an automatic transmission and it just becomes "frozen" in park mode. For instance- while waiting in a long line at the bank, I decided to shift out of gear until the line moved. It wouldn't budge. If an emergency situation arose- I would be unable to move. Many other Corvette owners are experiencing this same problem. Some of them have done a "fix" that bypassed other equipment and could be dangerous. My car only has 27,000 miles on it - this should not be happening! many of the other affected owners have gone to Chevrolet and have gotten the run around, because they say they need to see it happen in order to fix it. Well it happens randomly so that is a little hard.I think the problem is with a solenoid or safety feature that hangs up. Please help. I am a girl and I need a car that doesn't leave me stranded all the time!
