If you read my above posts you will see I just went through the same issue. First they checked my connections to throttle body and replaced my battery. Same issue so they replaced the wiring harness to the throttle body. Same issue so they replaced the throttle body. Currently the truck has gone 11 days and no Reduced engine power issue. My son has it at college so it has been driven very little so time will tell if the issue is resolved or not. Total bill for this, $1225.00 dollars. Did anyone from GM offer to offset the cost, not a chance. I have 5 GM vehicles currently dating from 1967 to 2007 and can tell you the ones from 2003 and newer are junk. Will be off shore next as much as I hate to but the quality and customer service from GM is far below standard. Good luck

Alls I did was put dry gas in along with premium gas and it has not done it again since. Bet most people get ripped off at the GM dealer. If I would have brought it in I'm sure they would have not put dry gas in .. they would have charged me hundreds if not thousands. Good Luck all dealing with GM they don't care.

I am more than ready to get in on a class action lawsuit! This is ridiculous how many cars are having this issue! I have filed a complaint at http://www.nhtsa.gov/. As long as we pull over
My Reduced Engine Power problem started yesterday. I have a 2003 Suburban and can only go 2-3 miles before losing power. I have 4 kids that I run back and forth to school and activites and this is DANGEROUS! My issued started yesterday where, thankfully, I was a few yards from my driveway. Each time it happpens, I can pull over, turn the car off, wait 10-15 seconds and then it cranks back up with no problem. The problem is within 2-3 miles, it happens again. I am having to drive everywhere with my hazard lights on. I only have one car so parking it is not an option but I am scared to death to drive the kids around! I have read all of the posts and have written a list of possible solutions, which my husband will try this evening. We're going to start with the easiest and least expensive and go from there. Wish me luck!

Not only does everyone need to file a complaint but we all need to post a link to this forum on other sites. This is only one of many sites where people are experiencing the same issues with GM. Collectively we have a better chance for a resolution or recall if we group together.
