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.

  • 400 miles


Bought new car; driven less than 400 miles; thudding noise noticed pretty much from day 1. got louder. Took it in. The right rear hub, and bearing assembly were faulty and had also damaged inner disc. The dealer fixed it but assurance of "faulty part, doesn't happen with Mazda" now does not ring true. This could have been a safety issue for me had I been driving long distance, for which this car was purchased.

  • 7,000 miles
While attempting to pull into a parking space with a 2016 Mazda Cx-5 (7000 miles) all of the warning lights on the dashboard lit up and the car started accelerating on its own (unintended acceleration). The brakes would not work! in an attempt to avoid the car parked in front of me I swerved to the right, unfortunately I hit the parked car with enough force to moved it about 12 feet forward. My vehicle continued going up an over a curbed median and finally came to rest approximately 100 feet away with enough force (brakes finally worked) to knock my glasses off as my head jerked forward. Vehicle was towed to the dealer and was examined and deemed "working as designed". supposedly, information was sent to Mazda usa engineers, the dealer states they found nothing unusual but have never given me a written report stating so even though I have requested it on multiple occasions. The dealer recommendation was to fix the damage to my car ($4400 worth) and then they would install a "special black box" and drive the vehicle for a few days. After driving the vehicle for 3 days, the dealer still says that nothing is wrong with the vehicle. We feel that Mazda Corp should take this vehicle back and inspect it thoroughly for unintended acceleration, as we do not feel comfortable driving this vehicle anymore.
