What's wrong with the plug wires? We have seen hundreds of these trucks and not a single plug wire issue.

a question:

you spoke to a rep, or someone from the dealer? a rep works for gm, not the dealer.

a few points:

plug wires are not considered an electrical issue

if you put on/had put on headers, and the plug wires were knocked off, its not warranty

I know a couple of people who had to have them replaced due to separating, and a few techs who say they slip off the coil or werent installed properly at the factory. I developed a misfire around 20k miles, one of mine had not been connected properly.

so it worked right for 20k miles then all of a sudden wasn't connected properly? sounds like bs to me...

It's not bs, there is a recall on some of the 14 trucks, suvs and vettes about the plug wires coming off.

so they just fall off the coil? that's what GM is wanting us to believe?

Basically. When built they didn't get them to seat all the way.

yeah. see that all the time. wires connected but not snapped, eventually through vibration, heat cycles etc they back off and cause an issue.

not just plug wires, but regular electrical connectors too. just fixed one on thursday for a 2014 that the parking sensors stopped working.
