Thanks for your sympathy bolivar, it is needed right now  A new update... The mechanic at my dealership checked out the TSB's, and said there is a TSB on the '08 Corvette's center tunnel shaft...it is described as "making harsh grinding noises at certain RPM's". Ok, so that sounds like it may be it. Oh, and the problem is less noticable with a passenger in the car...and the heavier the passenger, the less the sound is. So weight smooths out the noise/vibration somewhat. The mechanic said that would make sense. Anyway, he is at a conference this week with several Corvette techs, and he wants to run it by them before dropping the center shaft. Mabey just MABEY I might be getting some action here! But I'm still skeptical, and I will report more when I know more. Hopefully all of this reporting of my problem will benifit someone else who might be having similar issues. |

I have had it. the glove box latch broke off a month ago, and I still don't have the part from GM, they say it is on backorder. So I have been locked out of my glove-compartment. When I go over small dips or bumps in the road, the squeaks from the interior panels have been madening, even though it is improved over the C-5. WIth this new 08 Vette I have been in the shop 3 times, having sqeaks and creaks repaired. The auto-tranny shifts like hell when in "shift mode", and when you give it acceleration, and then let off, and then get on it again, you have no power! I mean wtf is that? Oh yeah, that other thing...the grinding noise that is coming from the back of the car when I accelerate. If I do not get a sufficiant answer and fix for the problem, and I mean this week, I'm just going to dump this car on the open market. I just might anyway, it's just not worth the headaches. I'll lose 10,000 in the process, but GM will lose me as a custermor forever! I can guarentee you the next time I shop for a sports car, I will be shopping at my local Porsche dealership. This experience has proven one thing to me...American cars are crappy. My Acura doesnt have any squeaks or rattles or ANYTHING wrong with it. I really wanted to enjoy a new Corvette, but this whole nightmare has been a harsh wake-up call to me. For their flagship car, I would think that General Motors could have done better.  *dissapointed and dissatasfied*

I think most Vette owners have my experience but every once in a while you hear a horror story like yours. Bummer for sure. Have you given any thought as to invoking the "Lemon Law" of your state. I don't know the nuances but it is something like "X" number of days in shop and "X" number of times without the dealer being able to remedy the problem(s), entitles you to a buy back from GM. Just a thought, and I wish you the best in getting this matter resolved. |

Thanks for your reply. I am wondering if there is a number to GM headquarters that I can call, and threatin a lemon law suit? Otherwise I guess I'll have to get an attorney. I will get an answer about the grinding sound tomorrow mabey, but what do you bet the answer will be "well, we dont know for sure about the center tunnel, so let's chalk it up to muffler resin"! I know I am jumping ahead by predicting that, but I have had similar experience before with both Ford and GM. |

Replying to: tmerriss (Dec 05, 2007 7:24 am) Second, I am truly sorry to hear of the issues you are having. The one issue I had ( 2007 Coupe - trouble w/A6 trans. ) was addressed with reasonable speed & efficiency by the dealer where I bought it. ( Largetst volume Corvette dealer in the S.E. ) Though the symptoms have started to re-appear. (( sigh )) Anyway, you could try: GM North America Vehicle Brand Marketing 200 Renaissance Center, Detroit, MI 48243 313-556-5000 General Manager Chevrolet Edward J. Peper Jr. And \ or: GM North America Vehicle Sales, Service & Marketing Group 100 Renaissance Center, Detroit, MI 48243 313-556-5000 GM North America VP Vehicle Sales, Service & Marketing Mark LaNeve GM North America VP Field Sales, Service & Parts Brent Dewar Good luck! |

Replying to: tmerriss (Dec 05, 2007 7:24 am) I think Lemon Laws vary from state to state but not sure of this. I want to think that before you can invoke the LL the dealer must have made 3 attempts at correction and the car must be out of service for "X" days. Don't know that number. You may want to GOOGLE Lemon Law and see what comes up. I thought the owners manual had a section for this but I don't see it in my manual. The manual does however have a "Customer Assistance Office" (see page 34 of your manual). The number is 800-222-1020. Keep us posted please.

Replying to: tmerriss (Nov 10, 2007 5:28 am) I was having a problem with the airbag light and had OnStar run a check on the car while on my way to the dealer. They came back with no problrem with the airbag system but the transmission showed a problem. While at the dealer for the OnStar upgrade, the airbag light problem and the rear seals they had incorrectly installed (leaking) two weeks earlier they confirmed there was a problem with first gear. Yes, I did say first gear, this is where all my trouble begins. Apparently, according to the mechanic, when changing first gear in the Tremec T-56 transmission you need to pull fifth gear. Again according to the mechanic every time you pull fifth gear the teeth break. So a routine Saturday wait for my car to be fixed turned into a "your part will be in on Monday and you will have the car back on Tuesday". That was three weeks ago tomorrow. From what I am told by the service manager they can't find a fifth gear anywhere in the F****ing United States. Let me back up to a week and a half into this ordeal. I called a friend who is the top Corvette mechanic (they do exist) at one of the Chevrolet dealerships in New York. I ran my problem by him and he had the following advice for me. First he said of the 80+ transmissions he had done the only fifth gear he broke was on the first one. After that he bought the right puller. Second he gave me the number of the place he purchases his transmission gears from. Within ten minutes I had found the gear they needed and relayed the information to my service manager. He said he would run it by his boss. A half hour later I get a call from the service manager saying they found one in Nashville Tenn. (I am in Ft. Lauderdale Fl.) and would be overnighting it. For those of you not familiar with the geographical oddities of Tenn. and Fl. I could drive the route round trip in 26 hours. Meanwhile let me fast forward to a week and a half later still no fifth gear. As of yesterday I was assured it would be here today and I would have the car back tomorrow. The message on my phone today from the service manager, as I was finishing up on 18, was "I still have not received the gear. He went on to say he would understand if I went over his head to his boss. The problem with that is his boss is the one that denied my request to replace the transmission and is supposed to be spearheading the search for the elusive fifth gear. This car has been a giant nightmare and dissapointment starting with the two weeks in the shop after I bought it and waited to drive it for the first time for a gas tank issue, two weeks out of service and three attempts to fix a leak in the firewall, five months to replace the recalled top (that's right five months). The top issue started on 04/07 and was finally delivered 09/07. In closing Corvette mechanics do exist but seem far and few inbetween. The service you get after buying GM's flagship car is very subpar (having owned an Infiniti G-35 prior to the Vette). Where do I start? I took my 2005 C-6 six speed in for an upgrade to the OnStar system. Almost a month later, as the car sits on the rack at the dealer, I have no 5th gear in the transmission. I was having a problem with the airbag light and had OnStar run a check on the car while on my way to the dealer. They came back with no problem with the airbag system but the transmission showed a problem. While at the dealer for the OnStar upgrade, the airbag light problem and the rear seals they had incorrectly installed (leaking) two weeks earlier they confirmed there was a problem with first gear. Yes, I did say first gear, this is where all my trouble begins. Apparently, according to the mechanic, when changing first gear in the Tremec T-56 transmission you need to pull fifth gear.

The top issue started on 04/07 (I had them order the part) and was finally delivered 09/07. In closing certified Corvette mechanics do exist but seem few and far between. The service you get after buying GM's flagship car is a disgrace (having owned an Infiniti G-35 prior to the Vette). If I was you I would forget about the noise or buy some earplugs, much less painful than the experience described above. And if you do decide to let them work on it, don’t take it to Ed Morse Chevrolet in Sunrise Florida. Oh, about the Lemon Law (Fl.) the car has to be out of service for 30 calendar days for the same repair or not fixed after the third attempt for the same repair. Any claims have to be within the first 24 months of delivery. Right now I have 24,000 miles on the car and have owned it for 2 ½ years. |
