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.

2010 Mazda MAZDA3 Owner Comments

During the summer there was a toxic smell that was making myself and others who rode in the vehicle ill. Dealership said the smell was probably the purge valve which was normal and that based on the smell my vehicle seemed to be purging more than others but there was nothing that could be done. Summer of 2014 the smell became extremely unbearable while in the vehicle I was suffering severe neurological symptoms, and burning sensations in my eyes and airways. People could smell the toxins just by opening the door. I noticed the heat damage to the dashboard and came across another Mazda owner who became ill because of the off-gassing from the plastic inside the vehicle so I ran the same test before trading in the vehicle. There is a toxic level of chemicals including formaldehyde. My apologies to the owner that this vehicle was resold to by the dealership, I hope you don't become as sick as I did.

  • 26,000 miles
I have had my 2010 Mazda 3S since June of 2010 when I bought it new. I drive to and from work every day. I have 26,000 miles on it, 75% of which are highway miles. I was driving to work last week, and noticed something with the car felt off. Every day of the week it got worse and worse, so I finally brought it to my mechanic who told me, as I suspected, that the clutch was slipping and nearing the end of its life. I have yet to replace the brake pads on this car, and to get told that the clutch is gone before I even replace normal maintenance items is just flat out unacceptable. I have had two previous cars with manual transmissions, and never replaced a clutch, even when they had close to 100,000 miles on them. My mechanic suggested before I do anything, to look on forums and see if anyone else has been having similar problems with premature clutch wear. I have spent my whole weekend on Mazda and edmunds forums reading about countless people with my model year, 2010, who have had clutches go before 35,000 miles. This is not a one-off case, and it is certainly not a "wear and tear" issue as the dealership says it is. That's their blanket cover-their-[xxx]statement because they know they put out a poor product and don't want to deal with the costs incurred with replacing them. I have no faith anymore in my local dealership, or Mazda as a brand at this point. With the significant number of similar issues to mine, the fact that they are still unwilling to admit that they chose an inferior supplier to cut costs for one of the most crucial parts of the car, that isn't covered under warranty, is just piss poor business practice. I don't know what writing this will do, if anything, but I decided that I am done being [xxx] around by the dealer and hopefully this is followed by other Mazda owners who share the distaste for their product and service as I do.

At less than 24,000 miles, my clutch has begun to slip terribly and creates a terrible burning smell. I know there are hundreds of other Mazda owners who have also had to replace their clutches before they've had to replace brake pads. This is a drain on consumers, and a safety issue to boot.
