#1 of 3 My 2007 H3 has a starting problem by awright2 Aug 24, 2009 (9:24 am)
I purchased a 2007 H3 this past June. I've enjoyed the vehicle for the first month until one day it stranded my wife and kids. The motor would crank, but wouldn't catch. After waiting about 10 minutes it started. This happend to her twice more so we took it back to the dealership for diagnosis. They couldn't duplicate the symptom but did find a tech notice saying the valve train needed to be replaced due to sticky valves that would cause the motor not to catch. They did the work and all was great for a month and then it did it again. This embarassing quirk is very intermittent. It always eventually starts but you're never sure how long to wait. And to clarify we have not moved any of the power seats prior to or after the problem. Replies to this message: dwh3 (Sep 17, 2009 4:20 am) awright2 (Sep 23, 2009 1:05 pm)

Replying to: dwh3 (Sep 17, 2009 4:20 am) Hey David, turns out it was sticky valves in the head. GM replaced the head under warranty and I haven't had any more trouble out of it. There is a recall for the 2006/2007 5 cylinder models and you should be able to have this taken care of at no cost.
