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.

2010 Toyota Sienna : when driving, the slightest touch of the gear shifter causes a shift into neutral. The gear shifter is extremely (and possibly dangerously?) sensitive.

There are multiple problems. Initially there was a whistling noise while driving. The dealer replaced the transmission of the brand new van. The whistling noise was reduced but there are a bunch of other problems. 1. on start the RPM goes to about 1600. 2. there is constant load humming noise coming from the transmission/engine. 3. the vehicle pickup makes a knocking noise sometimes overall I definitely don┐T feel safe driving this vehicle. The dealer and manufacturer says all this is considered to be ┐within normal range┐.
