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.

2005 Toyota Corolla did not pass emissions inspection. Car taken to lia Toyota, northampton, MA. Dealer said car computer needed to be replaced but had to order part from Toyota. So far it's been two weeks and the part may be delivered in another two weeks per Toyota. Over 1600 of these computers are on backorder with no delivery date supplied. I will have to pay for another emissions inspection, could E stopped by police and have my insurance increased for six years. I feel this is a known defect and Toyota is not really responding to me or other customers and because the pert (very expensive) cannot be supplied before 4/30 I am incurring additional expenses. It should not take a month to get a part. The dealership is waiting for 12 of these computers and is being shipped two and has 3 cars that don't even run.

We bought a 2005 Toyota Corolla in July of 2004. We have been extremely happy with the way the car runs mechanically never having any issues. Our vehicle is currently at 40,310 and we are experiencing a failure with the charcoal canister. In order to pass emissions for the state of nc we have to replace this particular part. Since our car is no longer covered under our basic 3 year, 36,000 mile warranty we are having to replace this part on our own. This is very discouraging since our vehicle is only 4,000 miles over our basic warranty coverage. This problem has occurred with many other Toyota Corolla vehicles around the same mileage. We feel this needs to be looked into because it seems odd that the charcoal canister fails around this mile marker in numerous vehicles. This is a component of the car the contributes to keeping our air clean. Toyota is failing to provide a car that will do so.

The consumer stated the vehicle smelled of sulfur, that was sickening to the consumer. The dealer stated that the sulfur content was common in these vehicles, however, the state law differs.

Purchased 2005 Toyota Corolla in August 2004. The car has had a consistent smell of rotten eggs (sulfur), almost daily with it worse when the car idles & after car shutoff. Dealer said try premium gas, which I did and no effect. Dealer said Toyota had no knowledge or suggestions about problem, although I am aware of a 5/28/04 service bulletin for 2003-2004 Corolla's for the exact problem. Dealer also said it could not be the catalytic converter because the dashboard light wasn't on, yet Toyota just settled a 2 million law suit for the dash lights not coming on and emission defects were not being picked up with regular code testing. Dealer mentioned a number of other persons brought their car in lately for same thing but suggested it was related to our current cold weather. When I mentioned the problem with my car has persisted since late August, a week after I bought the car, the dealer suggested the smell was from bad gas & the wind probably blew it into the car. My understanding is that this smell has been a very significant problem with Corolla's (& some other cars) and a number of 2005 owners on various discussion boards have also reported it. Sometimes, the smell is so strong that I have to put the window down & I wonder what the constant exposure to sulfus will do to my allergies and asthma and why I should continue to pollute the air with sulfur everyday while Toyota 's dealers treat me as if I am some neurotic patron.
