Hi John and Group, it was very interesting to read about your vibration. I just bought a 2011 ls460 awd swb, built 6/2011. I have exactly the same symptoms. My car has a vibration at 35 and 42 mph at around 1,000 to 1,2000 rpms. I also feel the vibration about 70 mph at 1,900 rpms. I did go back to the dealer were I bought the car, there is a software update for the transmission update# EG1206. This was done on my car last week. Sadly the car still vibrates. I have an appointment to drop the car off at dealer again this coming Wed. This car was sold new in July 2011 to another customer who returned it to the dealer on or about Jan 2012. The Salesman told me the customer fell in love with another car and just had to have the other car??? I know suspect the car was returned due to the vibration. I wanted to let you know incase you have not already found out there is now an LSB. It would be great to know if you have had your software updated and if it helped. I have no Idea what my dealer will do since the software update did not help?
Any other club members have this problem and or found a solution I would love to hear about it. Thank You
