excuse my english i'm from quebec... I just purchased a 2010 rx 350 sport package. I have vibration when accelerate as soon as a release the gaz the vibration stop... I bring the car to the dealer. The change the magnetic clutch differential. style vibrate. The change the shaft; style vibrate. tomorrow the will change the front axle... If the continue like that the will change the complete truck... i hope it's not only the tire... i have 19" michelin in good condition

 

My first thoughts are CV joints or Drive Axles, so I think they're on the right track, except they probably should have checked the axles to begin with. I'd make sure and have them check the CV Joints since you're going back up there anyway. Since it's under acceleration only, I doubt it's the tires, but I could be wrong. Good luck with it.

 

Correct, Mors. Tires would be prevalent all the time and not just under acceleration though can have a problem only at a given speed.

Let them change the complete truck if they have to, morin2726. You are under warranty. Hopefully, they have given you a nice loaner while yours is in the shop.

 

yes under warranty... and the lent me a 2014 rx350...

 

problem fix...yé!

 

Did they say what the problem was found to be?

Glad to hear all has ended well for you.

 

the last thing they change is the front axle
