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.

2006 madza 6 with transmission problems customer states that the car has been sitting at the dealership for a month and the car is still in disrepair** the consumer stated a few months after purchasing the vehicle, the vehicle began making a grinding metal sound. The consumer parked the vehicle looked under it and noticed fluid was spilling out. The consumer took the vehicle to the dealership and after 2 weeks the dealer stated the repair work was finished, however 3 days later, the consumer began to hear the same metal sound as before only this time, the consumer had no gears and no clutch. The consumer then received a call from he dealership stating the vehicle had blown a rod and there was a problem with the engine and not the transmission. The consumer was told he would need to provide receipts of oil changes or the vehicle would not be fixed.

There seems to be no one significant event that has lead up to the issues I am currently experiencing. The problem has gotten progressively worse with time over the last few months. It started with a minor stutter back in late July/early August. It worsened a few days after the computer was reflashed for the recall in early September. I'm not sure if that was a catalyst to this problem or not since it was stuttering before a little bit also. By late September the problem seemed to be worsening. By mid-October it was stuttering constantly when driving in stop and go traffic. The problem worsened with cool weather when the engine is cold. On nights below about 30 degrees, the car stutters and bucks severely for the first few minutes until the engine is warmed up. Acceleration is sometimes unpredictable during this time. So far, Mazda has replaced the mass air flow sensor and updated the ECU to the latest available as of November. Spark plugs were replaced prior to this per my request. Nothing seems to make an impact. It should also be noted that this problem (cold start) seems to worsen on rough/uneven roads. Gas type (93 or 94 and name brand) seems to make no noticeable impact.

: the contact stated while idling, a high pitch noise came from the engine. The noise was also present while driving at various speeds during normal road conditions. The vehicle was taken to the dealership who determined the noise came from the belt tensioner and replaced it. The noise persisted and after a short period of time, the dealership determined the water pump was the source of the noise and replaced the pump housing gasket. None of the repairs performed eliminated the noise and the manufacturer was contacted. Customer service collected the information but no solution was provided. The contact expressed concern about the inability of the mechanics to produce a solution in vehicle purchased brand new with only 1323 miles.
