I bought this car brand new, only have 45,000 miles on it, my engine lite came on and when I took it into the dealer they said I had bent valves. I can understand if I missed a gear or raced the car I would have this problem, but I drive the car moderately and not aggressively, this leads me to think that it is a manufacturing defect and not user error. I'd be interested to hear how many other Acura/Honda owners have had similar complaints.
