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.

Issue: My 2006 Toyota Sienna's ventilation system heats up even if setting at cold level. It caused the interior of the van to heat up uncontrollably and could cause heat exhaustion during hot summer days. The unwanted heat was traced from heat at the engine compartment enter the passenger cabin through the ventilation system. Due to insufficient insulated area at the engine compartment to the passenger compartment. It is extremely dangerous for young children in the vehicle during hot summer time. We noticed the issue during one of our summer vacation in 2007. We were stuck in heavy traffic for more than 15 minutes. Outside temperature was at a comfortable 75 degree, but the interior of vehicle feels like 90 degree. The air coming from the air vent is hot. I did some research on this issue, it turns out that Toyota fixed this issue on 2008 and later vehicles by adding insulation pad between the engine compartment and ventilation system. However, the Toyota dealership refuse to provide the fix to my van.
