loud rattle for a few seconds in the morning near the engine cover
. usually doesn't do it again until it is cold.
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.
Loud rattle noise when cold start. Only happens on the first start and usually last leas then 5 seconds.
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.
when i leave my car for 2 hours or soo it makes this rattling sounf then it goes away and when i leave my car for like 20 mins it doesnt happen again
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!
Replaced variable timing solenoid and clean two oil screen and changed motor oil 5w30 still rattle and cut off
