Last week took my 2008 w/ 8300 miles in for the “chattering rear end” (differential fluid change) and popping in the suspension (stabilizer links). Turns out that neither is covered by warranty or my GMPP, (3 year/36,000 mile expired in August). However, from searching Corvette Forum (CF), had the TSB’s on both when I went in to the dealer, and end result was my service rep got both covered by GM. During the verification of these issues however, the test drive revealed I needed a new clutch, due to mine having self-adjusted forward and this was not a warranty or GMPP issue but “normal wear” or “abuse”. Got back on the computer, searched CF for 2008 clutch failure, found a thread which detailed a problem with early production 2008 manual transmission clutches prematurely forward adjusting (PIP4318C). Again, took this to my service rep, which resulted in the new clutch, pilot bearings, pressure plate, etc. being covered by warranty.
With two searches of CF, savings of over $2,000, new clutch, differential fluid, stabilizer bar links, and a rental car for 5 days (including weekend).
I just wanted to take a moment and thank everyone who posts their issues and problem resolutions to this site, making CF a huge benefit to all Corvette owners.

Back in the Fall of 2000 when I had only been a member for a month or two, I had read about the sticking brake pedal that a batch of 2001 corvettes were suffering from after high engine rpm operation (obviously most of these cars were manual trannys where it is routine to go over 3000 rpm during shifting). Sure enough after I got 500 miles on my new 01Z06, my brake pedal stuck down on the first brake application after I had wound up the engine getting on the freeway for the first time. Had to use my foot to bring it back up. I knew what it was from the CF. I called my dealer service writer who had never heard of such a problem. I said "Call the GM Tech Center Hot Line and they will tell you all about it." Sure enough, later in the morning, my service advisor called and said I was right and a replacement vacuum brake booster was ordered to fix the problem. We will call when it comes in. Turns out that a batch of faulty vacuum boosters were built with out of tolerance tooling at that time period and installed on new vettes.
