Clunk feeling upon acceleration
Anyone experience a slight clunk feeling from dead stop under more aggressive acceleration...my 14 250 AWD has done this on 3 or 4 occasions. Just wondered if anyone else has felt it.

I'll be getting mine in two weeks so can't comment/confirm just yet but I never had this noise with my '08 250 AWD.

Did you double-check the jack and tire replacement equipment is tight (or just remove it for testing)? Have you tried to reproduce it from a rolling start instead of a dead stop?

Well guys gotta take the IS in tomorrow for the clunk or thump when accelerating hard from a stop on what only appears to be left turns. Sucks since this car has less than 600 miles but I don't think it's normal behavior. Thought it was my spare since nothing is in the trunk but I can clearly feel it under the car and my spare is tight.
Some have said it may be the trac control kicking in but it's not a loss of power, but rather mechanical in nature. Hope my car does not need major repairs already...tearing apart a new ride, while under warranty still makes me sick. I'll keep you all posted...anyone else experience anything similar??

I am definitely going to try this but it likely won't rectify the issue before tomorrow morning, so I'll test it out when I get the car back. Car drives beautifully aside from clunk feeling and noise and it does not do it under light acceleration, so I'm hoping its an easy fix. The fact that no one else has experienced this makes me a little nervous. Saying my prayers tonight it isn't a drive shaft or transmission issue.

since you are saying you are only hearing when accelerating hard in corners, then i would guess it is it... otherwise things that happen during hard acceleration would also happen when you brake (something loose).

Odds are very much in your favor (thousands to one) it's not a major mechanical issue. Regardless, if the foot brake trick doesn't do it or it's not the VSC kicking in as Spywolf suggests, relax, Lexus will take care of you and the car!

Valid points for sure guys!!! I'll keep you posted for sure after I hear back tomorrow. My dealership is great so I expect that they will make sure everything is legit.
