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.

2010 Mazda CX-9 Owner Comments

problem #1

Aug 272010


  • 1,500 miles


The contact owns a 2010 Mazda Cx-9. the contact stated that there was a loud ticking noise in the engine. Once the engine was cold the noise became extremely loud but when it was warm the noise ceased. The vehicle was taken to the dealer twice. The first time they stated that they corrected the problem by down loading information from the computer in reference to the PCM and told her that it was corrected. When she drove the vehicle it continued to make noise. She then returned the vehicle back to the dealer and they were diagnosing the failure for an entire week. The dealer informed her that it was the characteristics of the vehicle and it was inspected by Mazda engineers. The engineers told her that it was a normal sound compared to other vehicles and that her vehicle was just louder than the others. She did not call the manufacturer because the dealership told her that they would contact them. The vehicle was not repaired. The failure mileage was 1,500.
