I bought myself a H3 for xmax. I love it to death. More than my girlfriend. ooops /slap/slap. It's so much like my Jeep. The front windshield, steering wheel, just like a bigger more comfortable Jeep. Tuesday put some gas in my H3 drove down the road and at a stoplight it started shaking real bad, splattering my coffee all over the console. I thought maybe I had some bad gas. Went back to a gas station and topped off. My plan was yesterday to drive that tank of gas out and refill with something better. Well I didnt get far before my engine light came on. I pressed the Off-Star button and they told me my engine was misfiring. Please tell me I dont have Head\Valve problem. Im planning on driving to Chicago next week. Could bad gas do this? Maybe bad spark plug? I want a locking gas cap. Maybe some punk kids put something in my tank? lata

Sounds like you got it. Take it to the dealer and they should give you a loaner while the new head is being installed.

I should of made it clear. It's a 06 had 45 miles new, now 2190. Theres no way I did anything to the head. I was giving it 5000 miles before I step on the gas hard.

It's a manufacturer defect. There's really nothing you couldv'e done to prevent it.

Do you know exactly what the defect is?

From whatI understand...and I'm sure if I'm wrong someone will correct me...but the metal that makes up the head is soft and can deform leaving a gap between the head and the valve which thereby causes a loss of compression. If I'm wrong somebody will correct me I'm sure, but I believe that's what I was told.

You can also use the following to see if your vehicle falls into the "likely to have occur" range. Ifthe last 8 digits in yourVIN is less than68287591, there is a higher probability that you may be having this issue. Once GM acknowledged the problem, they create a new head casting midway through the year. the '07 models come with a different displacement and therefore different heads, so we are hoping not to go through this.

I did as per my previous posts (it happened to me while ON a road trip)..but then it is my understanding that this issue effects some differently.
