so this morning i started my car up in the cold and let it run for a little while before i backed out. i put it in reverse and when i started to back out i heard like a weird sound backing up like metal piping under the car was loose or something. i have not heard this sound before. i continued to hear it until the car was warmed up. even driving down the street when it was still somewhat cold i heard the noise. car is a year old have not had a single problem at all. should i be worried? what could this noise be?

 

its just weird driving in the cold vs the hot weather. i feel like when i drive in the cold here i hear alot more noises in the car that makes you think twice like something is wrong. i dont know if it just the cold weather makes the car make some weird noises or what but when i bring it to the hot weather i never hear i thing. any opinions?

 

how long does it take for the sound to go away? i notice the rumble of the big 3.7 going through my exhaust and sometimes it sounds like the pipes shudder from it. i like that though.

 

ya it takes usually 10-15 seconds then you dont hear anything. i havent heard it again and i have been driving daily
