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.

2007 Toyota Avalon Owner Comments

problem #1

Intermittently, upon heavy acceleration exhaust emits a hydrogen sulfide type (rotten egg) odor. Took to delivery dealer and tech could not duplicate &. took car to another dealer. Both dealers acknowledged that Toyota was aware of problem. Both stated that Toyota had replaced/repaired exhaust or catalytic converters. However subsequent to 2003 models Toyota would no longer offer repair or solution for my 2007 model. Service tech suggested using higher grade gasoline. I have used mid and premium grade gas with no change in result.
