Hi everyone

I am planning to get a used 2006 gs 300 awd. just wanting to get some feedback on the reliability and issues with the car before i go ahead. someone told me there are lots of issues with that model year.

thank you in advance

They are all pretty solid cars...no major issues from 06-present model years.

The MOST common problem plaguing the 3GS is the interior rattles.

The more significant (IMO) TSIB that came out for this platform is the "Cold Start Engine Rattle", which requires dismounting the valve covers, cams, etc.


goodluck in your search...

i have an 06 GS AWD rattle free for sale

if you not planning to lower it then its a pretty nice car.

Doesn't the engine issue only affect the 2GR-FSE (GS 350)?

Whoever said the GS 300 AWD had "lots of issues" probably just looked at a Consumer Reports press release:
integrity = rattles
body hardware = easier to dent/chip paint
sound system = not sure about this one, never seen anybody complain about it (except for the fact that it wont play MP3s).

Although there is no official data outlining which engine type is more prone on having the "Cold Start Rattles" (yet)....


I have to agree with you that it seems like the 2GR-FSE (GS350) is more prone on having this issue than the 300, and 430 engines....
I personally noticed this "trend" on this site's thread regarding "Cold Start Rattles" (2nd Gen IS, 3rd Gen GS).

I too is looking for a GS in Quebec, nothing is really available. All the car reviews i read is good on the 2006 gs, funny enough, no one has mention the rattles. I drove test 3 differents GS and only one has rattling in the back.

As time past, i will look into a GS 2007 instead.

i have an 06 300 RWD and the rear rattle happens occaisonally...not really sure why it doesn't happen all the time.

I have a '06 300 AWD that's rattle free now. Just had to get the dealer to fix them under warranty. If they weren't covered under warranty I probably would have left them or fixed them with the various tips on here. Mine was never that bad IMO.

I have a 2006 GS300 AWD & haven't noticed any rattling noise.

i am sure you can lower the awd without any problems.

you can but you can not lower it too much because then the cv axles start getting a weird angle on them as you go lower which causes vibrations.

We've got a 06 GS AWD with over 46k miles, been a great car, although we do have a couple of rattles when the weather gets cold. Don't plan on getting rid of it anytime soon either!

Except for the rattles, all the other problem the GS have is far and few in between.

Just get the rwd 300 I have a minor rattle in the rear but it may be caused from the L7 in the trunk, other than that its been great!
