While driving 65 mph down the interstate, my 2006 Mazda 6 made a loud noise like grinding gears and stalled for a second revved up and went into 3rd gear. The car went from 65 mph to almost a stop and then to 20 mph in the middle of the interstate. After that, the car downshifted several times in the next couple of days. Research showed many other 2006 Mazda 6 owners with similar problems. A Mazda tsb was posted in December 2006, and the car was purchased in November 2006. Mazda has not notified any costumers of this problem and a transmission going out at 58K is not typical. The dealer said it was the valve body solenoids. Replaced those for $800 and still shifted out of gear. Then paid $3800 for a new transmission that might do the same thing in a few thousand miles. If you are out of warranty, Mazda does nothing for you. This is a very serious rear end collision hazard.

Potential rear end collision: I own a 2006 Mazda 6 VIN [xxx]. I have experienced frequent times when I have accelerated onto the highway (or any other need to avoid a collision) and have experienced a severe loss of power/acceleration. This could have easily resulted in a rear-end collision had the cars behind me not reacted immediately. I have notified the local dealership and "Mazda customer satisfaction" of this problem and was told that my vehicle is "out of warranty. I also found that Mazda has issued a tsb #05-016-06 that explains the potential cause. Mazda is aware of this problem. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

2000 Mazda 626 - automatic transmission - 52K miles 1) no reverse - one time incident in may, moved it forwarded and ran through the other gears and then it went into reverse... so didn't think much of it. In late September, it happened again. Frequency increased over next month. No pattern... hot, cold, dry, wet, etc. 2) I now have no reverse most of the time, though still intermittent 3) took to aamco... it's not electrical, needs total overhaul for $2K 6 year old car with only 52K miles, not driven hard... shouldn't have these problems. I had a 1987 Mazda 626 that had the same issue at 11 years old.
