I deeply saddens me that my 3 year old GMC Sierra Is at the dealer getting new lifters and valves. I took such good care of this truck. Was driving my truck all of a sudden started idleing rough. Call ONSTAR they told me it has a engine misfire. Go to service ASAP. Then to my surprise I get the news. I was alway a die hard GM guy.Maybe its time to move on and try a Ford.

 

If it's under warranty don't take it so bad. If it's not under warranty I feel your pain.
