Ok so I purchased a "certified" infiniti g35 sedan (2005 5at). It has 47k miles on it and runs great and rides great. I absolutely love it. There is one small thing though. And for me its not small because I'm insane about little noises. So basically every time i start the car after its been sitting for a while, once I start to take off (even if I'm easy on the throttle) there is a short sort of creaking noise (not exactly but thats the best i could do on a description) that seems to be coming from the engine bay or wheel well in the front drivers side. It only does it once and then is fine until it sits for a little while. Any ideas on what this could be? I'm taking the car back into them to tie up some loose ends tomorrow morning so any responses would be greatly appreciated.

 

Normal. It is the ABS self test, occurs every time you start the car and start accelerating more than ~5mph.

 

Ye, if its making a spring kind of noise and then goes away its usually abs check

 

yes your ABS check, i was tripping out when I first got my car too

 

hahaha so thats what it is! I always thought my PS pulley was loose and when i go faster it goes aways

 

^+1, Always wondered about that.

 

same here. I've been hearing that noise as soon as I pull away from my drive. Reminded me of the air brakes you hear in a roller coaster station.

 

THANKS!!!! I will sleep better tonight. Taking her into the dealer tomorrow to get a coupe door dings taken out and the car buffed and detailed. Anyone know what all is actually involved in the "certification" process that i paid 800 bux for?

 

lol, should have aquired that before paying the $800.

i have no idea.

 

Like road certification? That cost you $800???

 

Here you go:

Infiniti Certified Pre-Owned

FWIW I bought my '06 in December with 42k on the clock and had the option of getting CPO for another $800 as well but opted not to.

 

Oh nice, i was going to make a thread about this but good thing you made this thanks everyone.

 

yap get same thing funny thing never really noticed it untill last couple of weeks

 

Once again this is why I love forums!

I'm a new G35 coupe owner myself (Supercharged no less), and as this is a used vehicle, and i've not had other cars make this sound - including all those previously with ABS - I was more than a little freaked out by this sound.

If possible can anyone elaborate on the mechanical process that is happening under the bonnet which makes this sound? Call me a tech nerd when it comes to my cars, but I'd honestly like to know
