Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2011 Toyota Highlander Owner Comments

Vehicle makes a very noticeable, irritating whine or whistle noise when accelerating at 40mph. Stops when gas pedal is released. Very constant and annoying. Did not happen when car was first purchased. Have been told by Toyota that it was the transfer case, which they replaced. Did not fix the problem. Now they tell me it is normal. Test drove another vehicle from their lot of the same exact year, make, model. No noise at all. This is not normal. Toyota knows about the problem, but they are denying it. Other Toyota vehicles (I.e. rav4, Tundra) had/have the same problem. Forums tell me it is the transmission. Waiting on appointment for a field tech from Toyota to examine it.
