hi all,

im not sure if there is a post on this subject,.. about a year ago i notice this vibration and took it to my local lexus shop they stated that my engine mount is bad. bought the mount from lexus and change and vibration is still there...,my question is am i the only one that is having this engine vibration problem or this a common problem for the 06-11 awd.? any info will help. thank you

 

How many mounts did you change? You should change 2 engine mounts and the trans mount at this same time

 

When was the last time you replaced your spark plugs? Are you lowered?

Rarely do 3GS GS350 motor mounts go out, unless you're a really aggressive driver. On higher mileage AWD the front cv axles can wear and cause slack in the transmission causing a vibration at idle.

You can see if the dealer is willing to put the car in idle on a rack and have a tech pin point exactly where the vibration is coming from.

 

i change all three mount

 

bought my car new. i only have 83k on it. not sure why my car is vibration. dealer can't even figure it out. my car been in the dealer for 2.5 weeks.

 

Do you have any oil consumption issues? Have they checked for carbon build up yet? Is the vibration at idle only or when moving

 

all vibration when idle.

 

Have you changed the spark plugs with oem plugs? If not I would do so

 

yes at 55k

 

OEM plugs?

 

yes all oem parts

 

Any resolution for 2007 Lexus gs 350 awd vibration while idle. Been to 3 mechanic shops and I mentioned motor mounts. They said my mounts look good. Can it still be the mounts as the vibration is a pain.

 

Some say its the torque convertor being very sensitive to the transmission fluid.

 

Vibration only happens in D, right? It's probably some doohickey in your transmission.
