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.

I have experienced this since the beginning of the purchase. I use the air condition. If I am done, I turn the ac off. After using the ac, there is a foul odor that arises. I have tried to open up the vents. I have checked underneath the car. I have opened the front where it leads to the cabin filter. I have changed the cabin filter several times. The odor still persists. The only thing that the car dealers have told me to do was to run the heater after using the ac. It is redundant if I have to run the heater in a hot day.

1. while driving with ac on water was leaking down into the passenger side carpet. Dealer checked and found that the A/C drain hose was clogged. This happened on July 10th. 2013. Dealer did not charge for cleaning clogged drain. 2. on July 8th 2015, the same condition occurred and took it into the dealer. Dealer diagnosed A/C drain clogged and caused water to back up into the oxygen sensor causing the "check engine " and "trac off" lights to come on. Dealer now charged $252.59 and stated that this is not covered by warranty. This is the second time and it is affecting the engine. I need to have this situation fixed before it occurrs again and cause serious accident or death to occupant.
