why our c5s fail







just my $.02
Unfortunately, GM was under a tight budget for the C5 and therefore most of the electronic components were not manufactured to last forever. They could've been but, the price would have skyrocketed. Having said that, the electronics in the C5 are quite reliable relatively speaking.

so I think GM did a pretty good job building them. It has been problem free other than a water pump at 100K and a couple minor fluid leaks that were easy fixes.
The Best of Corvette for Corvette Enthusiasts

To throw my nickel in the pot: I must agree with the guys that said we only hear about the failures. How many people would really start a thread to say that their C5 DIDN'T act up or give them problems?! I wouldn't expect anyone to do so...
That being said...to a certain extent, the OP has a point. The "harsh" driving environment increases the likelihood that an electronic component could fail...but certainly such things are accounted for during the design phase of a vehicle.
In my experience, outdated electronics do not fail because of age. I've personally seen control modules and instrumentation whose technology is older than I am...and it functioned just as reliably as the day it was built!
That being said, my C5 suffers from a bad SWPS...and, knock on wood, that's it. Oh sure, some random codes here and there when the battery gets disconnected, but everyone experiences that. Am I going to ditch my beloved Corvette simply because the technology is over 10 years old?...absolutely NOT! That'd be like throwing out my perfectly good iPod that I bought in 2005 just because there are newer, more advanced versions. Never mind how much money I've poured into the 'vette!

The system cost just in excess of $1600 new. So, comparable to Corvette $. Difference being, I got quality components with the computer. The Video card (super high end gaming card of its day) still works today. It also is not in the system cause I wanted one that did HD Video. So, like sticking on a set of headers, I removed working stuff and replaced it.
It still has the original OCZ Power supply, original DVD Writer, same keyboard & mouse. The two monitors it began with were almost 10 years old when the system was new, so they are gone. (they were also Corvette $, when 21" monitors were $2000 each). One of them is here at work to this day, nearly 20 years old. I replaced both when one died.
So, if you bought a consumer grade pos computer, then I would expect it to perform and last about like a Datsun B210. However, when an item commands top dollar new, you expect top quality. In the case of many of our cars components, you paid Corvette $, and got B210 quality. Sometimes not even... Ask anyone who's changed a oil pressure sensor twice what they think.
