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.

I own a 2006 Mazda speed6 with 96,600 miles, purchased December 2005. My speed6 has always had a turbocharger smoking problem. At one point, it looked like a mosquito spraying truck going down the road. But that issue seemed to abate, and appeared to be under control on its own. Now the car is burning a quart of oil every 300 miles. That is not acceptable, and after a yearlong attempt to watch the problem, to see if it could be controlled, I finally came to the conclusion, that it could not, and that the turbocharged had to be replaced. I thus made an appointment with the Mazda dealer closest to my current residence, paducah Mazda, in paducah, ky. I took the car in yesterday, and it was confirmed that oil was leaking from my turbocharger seals. This problem has been well known and prevalent, subject to a NHTSA inquiry #10043874. And as a result Mazda issued a letter extending the warranty for this problem to 84 months or 70,000 miles. I do not recall receiving this letter, or if I did, at that time did not believe I had a problem worthy of a new turbocharger. So yesterday, the Mazda confirmed the problem, and gave me an estimate of $2500 to replace the turbocharger. Since this issue has been well known, documented, and subject of a Mazda warranty consideration, I called Mazda consumer service to see if Mazda could offer any assistance on this service issue. I offered to work with them, to pay some portion of the repair, meet them in the middle if possible. My request was denied in total; "no assistance". naturally, I am disappointed with this result, given that I have been a loyal Mazda owner. I am very surprised with this abrupt and negative treatment from Mazda, given the history of this problem.

For more than a year now we have complained to Mazda about the variable valve timing noise and the heavy white smoke from the leaking turbo. These complaints were done under the extended warranty. Mazda chose to ignore the issues and brush them off. The car needs repairs due to this matter. Mazda needs to be forced into a total recall to repair these many complaints.

Driving the car on the turnpike and heard what sounded like a blowout. Immediately pulled car to the side of the road. Noticed the engine was not running. Attempted to restart, but made noise and would not start. Called husband, who arrived and said the engine had come apart. There were physical pieces of the engine block up to the size of a golf ball in the skid plate under the engine, as well as oil underneath the car and on the road. We had received a letter from Mazda a few weeks earlier indicating a problem with the seals in the turbo and a stop pin in the variable valve timing (vvt) and if the vehicle exhibited any of the symptoms to bring it to the dealer for evaluation and repair, up to 7 years/70K miles. Called dealer and Mazda hq next morning. Mazda customer relations acted if they were interested in the root cause and reason for failure, especially since it was 1K miles out of the coverage period. Mazda paid for tow to dealer, but once there Mazda customer relations wanted me to pay for the engine teardown and began to dance around the warranty extension for the vvt problem informing me that Mazda is rigid on the 7yrs/70K miles. I questioned Mazda on the discussion the previous day regarding the post-mortem teardown and analysis, where I was given the impression Mazda would take care of the tow and the teardown to determine root cause of the failure and then the claim would be evaluated from there. Mazda did a complete turn around and would not honor their initial word, now informing me I would be financially responsible for any work performed on the car.
