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: Except for a minor issue with cracked motor mounts, the 2007 MAZDA3 is a fantastic vehicle with a great reputation.

If you need to replace the motor mounts, first ask your dealer if they'll cover it -- the motor mounts were dealt with in a TSB & were recalled for some model years. Otherwise buy aftermarket motor mounts -- owners report this solves the problem. If you use the same OEM parts, they may just crack again.

2007 Mazda MAZDA3 Owner Comments

  • 80,000 miles


The contact owns a 2007 Mazda 3. whenever the transmission was in 3rd gear it slips into neutral, which makes the vehicle drift backwards. Also when driving up a hill the vehicle will slip into neutral instead of third gear. He was in the process of taking the vehicle to the dealer. The failure mileage was 80,000.

problem #1

Nov 112009


  • 38,000 miles
Clutch pedal was depressed, shifting from 3rd to 2nd as the gear lever hit neutral there was a faint popping noise, clutch pedal froze in the down position, I sensed something wrong and allowed forward momentum to pull to the curb. I attempted to finish shifting, gears were unusable, clutch pedal frozen down. This all occurred in a half a second or less. Luckily I was in the right lane and there was surprisingly little traffic. 2 blocks further and this would have occurred in heavy rush hour traffic at 65 miles an hour. After 5 minutes of making phone calls for assistance, the clutch pedal released and I was able to slowly limp to the dealership. There were no prior signs of clutch wear except for a couple prior days in which the clutch felt a little softer then normal but so little I couldn't tell if was the new shoes or the car. The car has 38,000 miles. It is used primarily to get to work with 50/50 street and highway driving and roughly 36 miles a day. With 4 models of this brand over 20 years I have never had a clutch repair with an average life of 90-100K miles.
