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.

At just under 16,000 miles I am hearing a rattle upon start up in the morning or after the car has been sitting for a few days. It quickly goes away and doesn't happen anymore for the rest of the day. I have an appointment with the dealership to correct the problem. It is still under factory warranty. Im glad to hear other people have experienced the same issue. I love this car and want it fixed. Ive had it 3 years and have had no other issues at this time.
