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.

problem #4

Feb 272016


  • 32,600 miles


Upon turning on my car (flat surface, middle of the day, already driven that morning), I received an at failure notice, master warning light, scbs failure notice, and a check engine light. The car had been seen 5 days prior for a routine oil change and inspection. All marks were noted as "green." The engine sounded fine, the shifting of the transmission smooth, and no issues were seen/felt/heard/noticed as of yet. The dealer refused to run a diagnostics test as it is a Saturday.

Driving through rain in our neighborhood and the car stalled and will not restart. Engine seize per dealer. We understand other Mazda's have been recalled due to this issue. We requested the car to be checked for a possible recall without success because our VIN does not fall in the recall. We offered to pay out of pocket for them to test it which they declined to do.

While accelerating on 2 occasions in past 2 months, the engine will lose power without warning. It is still running but will not go faster than about 10 miles an hour. The first time occured while pulling out on a road and almost caused a collision and the second time was on a busy interstate while passing a vehicle and had to coast to the side of the road. The engine light flashes and the stability control light comes on. It will work normally after restarting the engine and it clears the lights. I had it looked at by a Mazda dealership the first time and they said it was a cracked spark plug and replaced it. However, the problem just happened again.. please investigate as this is a significant safety concern!

MAZDA6 4-cyl

  • 1,500 miles
This incident has happened about 10 - 15 times in the 6 months I have had this car. It occurs when the vehicle is stopped at a traffic signal, stuck in traffic, or any other time when the transmission is in drive and the brake is used to keep the vehicle stationary. The engine will be turning at idle speed when suddenly it revs to 4-5K RPM causing the car to leap forward, overpowering the brake. This has almost resulted in a crash several times as suddenly the car moves forward rapidly. I have noticed a small tendency for this to occur in the first few minutes of driving but it has happened anytime. I have seen no correlation to outside temperature. I have noticed perhaps a small increase in frequency when the car is stopped after high speed driving such as highway driving.
