I had read the threads about the rattle noise when cold start. My car now has 5,400 miles on it and i just noticed the noise when cold start. I know your guys stated that the TSB or TSIB....I dont know much about engine can your guy explain to me what is TSB.... Uhm Im so disappointed at our car and plus my car only 5k miles range and has many problems already.. the dash is rattle and the both passenger and drive sides' doors are rattle. and my car now is vibration a liltle more than when i first got it. What happene if I dont fix the rattle noise when start up? Because I read the thread and somebody got it fix they have to replace many parts from the engine component. Anyone have advice. Also in a long run would the TSB hurt?
Should I bring it to dealer to get it fix or leave it alone.. I already saved the video of somebody posted about the rattle noise.
OH one more thing.. does any IS F owner got this problem...

 

Bring it to the dealership they'll know what to do. Just tell them you have the start up noise.

 

ISuxel do you know how long it take them to fix it. What they are gonna do? I live 2 hrs away from the dealer.

 

It's going to be a couple of days. You'll get a loaner.
