I put 80,000 miles on my C4 Vette, and had these problems.
1. Exhaust manifold came loose, fixed under warranty.
2. Three separate and distinct electrical problems, all due to workmanship at the factory, ie: cable tie pulled too tight, broke wire inside of insulation, stuff like that. Fixed them myself, with the aid of the electrical manual.
3. Ignition coil pack gave up, stranded me on the freeway, fixed under warranty. Good thing I was close to home!
4. Replaced antenna several times out of warranty. Got so good at it, had the task down to just minutes. GM replacement was made in Japan, which surprised me, since Japan usually makes some good stuff. But that antenna mechanism was nothing but cr*p.
5. Minor adjustments of deck and hood release cables, normal due to cable stretch. Surprising to see so many C4s going down the road with their convertible tops askew, because the owner didn't know how to adjust the latch cables.
6. Center glovebox trim cracked, where my elbow leaned on it. Never fixed that, just sold it that way.
7. Electronic air conditioning controls quit working, took off front circuit board, cleaned touch key pad contacts, reassembled, worked fine after that.
I might have had more problems with the Vette if I had tracked it, like I do my Viper.
My 2001 GTS has 20,000 miles, and I have had these problems,
1. Water pump impeller sliping on shaft, bad run of pumps in 2001, fixed under warranty, never came back.
2. Shift lever wouldn't return to center, when pulled to the left, if in nuetral. Not really a big deal, but annoying. Fixed under warranty. Replacement tranny is balky going into 1st, synchro seems a little sticky or something. Viper tech says he can't replicate it, but I'll take it back there, when I have time. Borg-Warner was a good company, but when Allied bought them, they moved the plant to Mexico, and now the "Tremec", as it is now known, is a pile of dog spit, in my humble opinion. Same tranny in many other cars, so not peculiar to the Viper.
3. Trim pieces inside the car crack easily, kinda shabby. But fixed under warranty, no problem. I took steps to prevent the same cracks on the new pieces by shimming behind them in the areas where they are subjected to stress from my elbow, etc.
4. Right rear wheel hub was making a clunking noise under acceleration. Replaced under warranty.
5. Ball joint rubber grease retainer boot cracked, probably cause track time subjects them to massive heat. Replaced under warranty. Now I know to do what the road racers do, and wrap the ball joints in heat shielding.
5. Throttle position sensor was putting out too little voltage, fooling the PCM into thinking the throttle wasn't open as far as it really was. This threw the mixture off, and resulted in a "multiple misfires" fault code. New throttle position sensor fixed the problem, thanks to John Horton of West Coast Vipers. Saved my day at the track!
6. Top quality "Alpine" stereo quits playing CD's on a long drive. Let it cool for a while, and it plays again. Hey, that reminds me, I gotta take it in for that.
I really liked my Vette, and was very pleased with it. If it had more power, I might not have sold it at all.
But the Viper is singularly THE best car ownership experience I have had, out of the 20 or so new cars that me and my wifey have bought. Its the most dramatic, most exciting, best performing, wildest looking, most head turning, sexiest, most beautiful and agressive, unique, most satisfying car to own that I have ever had. Whatever you say about Vipers, you gotta admit, that Dodge put something great in the hands of the American automotive enthusiast.
