Two problems related to structure have been reported for the 2009 Honda Odyssey. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2009 Honda Odyssey based on all problems reported for the 2009 Odyssey.
We own a 2009 Honda Odyssey that recently experienced failed gas struts in the hatch. As a result, my wife was struck in the head injuring her. Honda agreed to repair even though it is out of the 36k miles warranty. There is a recall for the 2009 Odyssey for the exact same failure mode, but only for the motorized hatch. (ours is not motorized). I would like you to look into the possibility of having Honda increase the scope of the recall to include non-motorized hatches. The dealer took possession of the gas struts from the hatch as they indicated Honda of America demanded the parts for their own research. I was not able to hold onto them. Besides the obvious injury my wife incurred, my young toddler twins were also at risk if they happened to be near the hatch and it collapsed.
The back hatch on my 2009 Honda Odyssey slams shut and will not hold. The hatch slams with incredible force and if any of my 3 kids are in the vicinity it could cause serious injury. A vehicle less than 2 years old should not have this type of issue. I have a full front to back warranty and apparently it does not cover the back hatch.
