Loud succession of rattling sounds immediately after cold start. Lasts maybe 2-3 seconds. Goes away after car warmed up which makes it impossible to show someone unless they hold the car overnight.
On first startup, rattle noise heard from engine bay, once in a blue moon but annoying.

At 35-45 mph I get a shudder as if I am going over rumble strips, the dealer recommend a new transmission $3200.00, I think not. For the cold start rattle they suggested replacing the timing chain because I have an oil leak, $542.00, more doable than a transmission. I will be looking for a certified pre-owned real soon!
My 2009 TSX has an intermittent rattle or ping when accelerating. It doesn't seem to matter if at low or higher speed. Took it to the dealer a couple of times when first noticed and they said they could not duplicate the issue while test driving it. It's been a couple of years, so I will check with them again.
