I had to replace rear suspension within first year & Honda dealer told me is very common; bad suspension on 07 Hondas, but once replaced will last forever-so why not a factory defect!? then at 3 years something in front suspension, same story. Now the vtc actuator needs replacement-rumbling noise at startup for less than a minute, which I'm finding out is the case with a lot of Hondas now, old & brand new. Old Hondas used to last; used to be excellent & all I've driven past 25 years. Now the Honda brand is unreliable - loyal Honda owners like me, after 25 years driving only Honda, are switching brands. Honda is not the reliable car it once was. I will never buy Honda again because of major problems I had on my 07 right from the start (I bought my 07 Honda brand new in 08) & had problems I never saw before in the past even with 15+-year old Hondas.
