Rattle heard from outside of car (exhaust?)

3391 13
Theres a rattle coming from the outside of my car. It happens under half acceleration throughout the low RPM's. Anyone know what could cause this?

I also have a TPM Malfunction warning that is going off intermittently..

Bringing the car to the dealer soon for those two issues and a broken soft-close on the drivers side door.

Thanks..

Get under your car and start banging around with the palm of your hand to find the rattle.....good luck

I have one when the car is idling. Touch the throttle and it goes away. I too thought it was coming from the exhaust yet recently i just added headers and still have it :confused:

maybe when they installed the exhaust the put it back incorrectly and the clamps are hitting the under panel... My clamps are about 1/2 inch from the metal underpanel...

Mine is exactly that way since day one when she was new. Low RPM throttle in the bottom of 2nd, 3rd, 4th, you hear this distinct rattling sound and it goes away after the RPM starts to build. I am actually gonna bring this up to my SA on my next visit. Sounds like something is loose from the factory... I don't think it has anything to do with headers/ aftermarket exhausts... because mine was like that from day one.

Let me know what you SA says because my SA can't think for himself.

I also have a door issue since day 1.

Mine developed a rear-end sheet-metal rattle after Dinan suspension was installed. An exhaust system hanger had not been tightened during reinstall.
