Mr. Bugs
 I purchased my SE-R 7 weeks ago and it has been in the shop 4 times, it makes a strange sound similar to hissing or a shaking a filament in a light bulb when the car travels over any street that is not newly paved.  At this time the dealership as not been able to pinpoint the problem.  They have replaced struts and strut mounts so far.  My driver side door froze and would not open. The car is due back in the shop to replace a broken positive battery terminal connector that is on order.  I love the engine power and styling but my car seems to have a lot of bugs and problems to be only a year old.
