Recently (Like before winter) there has been a soft thudding coming from the back of my car. Nothing is in my trunk. I will drive for a while and wait till the car warms up and when I am at a stop light with no sound you hear a steady semi pattern rythmic thumping coming from the back. like a thump, then wait 2 seconds, thump, wait 3-4 seconds, thump thump, wait 2 seconds. I don't know what it is. My exhaust isn't loose and I have no idea what to do about it. Grrrr... My car is driving me nuts and it only has 160 horses!

 

If your car is a 06 or 07 take it to the dealer to see if you need the rear upper control arms and flange bolts replaced under TSB 08-001. The problem may be uneven wear on your rear tires caused by faulty components......if you have more the 25K on the tires they will tell you to take a hike! But the repair and alignment will we covered by Honda. Good luck!

 

Oh, sorry it is an 02 Honda Civic Si Hatchback. EP3. Would I still have to check these on an EP3? Nothing is warrantied.
