problem #4

Lost clutch to the floor while driving nearly having an accident. Took off clutch master cylinder as symptoms would suggest the repair would be. Found out that the pedal assembly is broke and that the firewall is "cracked" I can see lots of posts online where this seems to be very common and very dangerous

5 months ago, took car to Mazda dealer for timing chain, vvt noise and was replaced under extended warranty. Last month started to feel intermittent loss of power during quick acceleration followed by plume of smoke at the tail pipe. Took to local mechanic shop and was told there was heavy carbon buildup at the valves as well as mass air flow sensor, O2 sensor, and other engine components. The bill was for about 1800 worth of parts and labor for deep cleaning the valves (intake manifold removed). After repairs were completed, took car home and drove for about 25 miles when I heard a loud bang from the engine compartment. The engine suddenly stopped and I smelled burnt oil and smoke inside the cabin. I was able to steer the car to the side and looked under the car to find large amounts of oil leaking from engine. Had the car towed to same mechanic and was told a rod sheared and blew a hole through the block and punctured through the transfer case housing. There was no rod bearing failure, the rod just snapped in half. The extended warranty will not cover the entire repair cost and will not cover the transfer case damage. Reading through several forums, the same engine damage has occurred to several other mazdaspeed 6 owners. This type of engine failure appears to be a manufacturing defect. An investigation should be conducted to determine the root cause of these catastrophic engine failures.

The mounts and the bolts that hold the rear differential mounts keep breaking. This has occurred over 5 times and is a well known issue with this car.

The contact owns a 2006 Mazda Mazdaspeed6. The contact stated that while driving at various speeds, the transmission would slip into neutral without warning. The contact mentioned that while decelerating to attempt a turn, the vehicle automatically downshifted. The vehicle was taken to the dealer. The technician advised that the transmission was defective and needed to be replaced. The manufacturer was made aware of the failure but did not offer any assistance since the vehicle was no longer under warranty. The vehicle was not repaired. The failure mileage was 38,000 and the current mileage was 55,000.
