5 Engine Cooling System problem of the 1997 GMC Sonoma

Failure Date: 05/05/2002

We have a 1997 GMC Sonoma with a votrec 4. 3 x. Over 2 years ago, we started getting misfires. We tried everything we could think of, to no avail. In the past month I've put over $500 alone. I have been looking it up on-line, and have realized, I'm not the only one with this issue. There has even been a recall in California, but only there. Gm told me they have different gas out there. Another major safety issue has been the wiper motor failure, that had a recall. Gm told me my VIN # was not on the list, but I battle my wipers at least once a month. I have to yank the blades half way up the window before they grab and start to work. One more problem that I now know I am not alone on is the issue with dex-cool. We have flushed and refilled the system at least three times, only to have it gunk-up again. Please help me and all the other customers who got trapped with junk vehicles. We have had too many other failures to count!.
