    About 6 months ago my truck started the same misfire problems I've been reading from other owners.
    I have taken my truck to be looked at,and I was told that it would be around $2500 to $3000 for repairs.
    It's something when you spend $30.000 for a truck and take very good care of it,inside and out.and the dealer you bought it from tells you.he has had many reports about the same problem.Why is there not a recall put in place for this problem.I am the last person to beat up my truck or drive it like a teenager.This issue needs to be addressed to the manufacture and a recall needs to be put inplace.

    So, I just failed my emission test. Said my # 5 cylinder is misfiring. I replaced coil and plug with no change. Now I find out that GM has valve seat problems with this engine. If it is a common problem do you think GM will stand behind their engines and repair them or do I have to pay the total amount >|???
