First time writing on this site. Interesting reading this thread.
Purchased my 09 Euro in July 08 - auto.
Pinging or rattling type sound developed within a 1 or 2 thousand klms. Currently nearly 8,000 klms & problem seems to be be less frequent but still there! Not sure if the engine loosening up abit is helping things.
I use Shell V-Power normally & sound is occuring around the 2 to 3 thousand rev mark. Does occur more under load (as mentioned by others) & more when colder or after a restart when already warm, then problem eases with driving somewhat.
Up for 10k service this month & will definitely raise the concern with the service centre & report anything back of use. When I raised it briefly last time the guy at the service centre tried to tell me it was the v-tec or variable cam that causes some rattle???? Not sure of that.
Also had a tinny rattle develop in the rear seat / shelf area (as previously mentioned by someone), twice, but was repaired by Honda x2, by pulling apart & realigning the rear seat supports - at least that is what I was told. If it happens again I will insist on a more permanent repair.
Someone commented on slow acceleration on their model. I noted this also but again, as the klms have been done the performance has picked up. Possibly again due to the engine loosening up abit. Given the weight of this car & being a revvy 4 cyl, the paddles & 's' mode do get some working as the useful power of the engine is higher up the rev range!
Just some observations that might be of interest.
Otherwise happy with car. Just didn't expect Jap built Honda to have problems such as these & those mentioned by others.
