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. Notes: So far Mazda seems to have fixed the serious engine & A/C defects that plagued the 2007-2010 CX-7s. We're giving it a tentative "Good" rating for now.

Purchased (new) - July 4th, 2011. One month in, the front driver tire blows out on the 55 freeway in costa mesa. The car is driven to the dealer the next day - to have a tire placed on. The price was surely "surprise surprise" - $250. We push to know why the tire was so expensive, it's because the size is new for this size vehicle and there's one maker of the tire. Bridgestone. We pay for it begrudgingly, and go about our way. February 6th, 2015, 3 years, 6 months of owning the vehicle. The vehicle history is good, maintenance is excellent (my wife is a therapist for children with autism so that's why vehicle choice was extremely important - traveling client to client in administering therapy sessions) and without warning, she cannot reverse. Car can drive forward, yet is losing power when the automatic attempts to shift from 1st to 2nd gear, so it jumps from first to 3rd. We take the vehicle to browning Mazda in cerritos and we are advised that the transmission needs to be replaced ($3,200). 3 years 6 months 64,262 miles, excellent maintenance history, & this vehicle needs a new transmission" this felt like a terrible joke. The power train warranty" 3Y/60K. Expired just over 4,000 miles ago. We contact Mazda (corporate) & are advised later in the day that they would pay half of the ticketed amount. That's still egregious as there wouldn't be a vehicle sold if most buyers knew that at such ridiculously low mileage, the transmission would fail them. We retrieve the vehicle and have it looked at for two more opinions and apparently there are no codes indicating the transmission is bad, yet it's obviously the transmission according to the mechanic as indicated simply by the test drive.

The contact owns a 2011 Mazda Cx-7. the contact stated that while driving approximately 65 mph with the air conditioner activated, the vehicle was making a banging and rattling sound. The contact stated the sound was also heard when the turbo was activated. The failure would occur with or without the air conditioner activated. The vehicle was taken to the dealer who was unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 14.
