Car-2006 mazda speed 6-mazda hit a pickup---slid sideways into the center guardrail--rear end then hit the side guard rail---front end then ran into the center guard rail and was lodge in center guard rail. Neither the side or front air bags deployed.
Takata recall 8 months since the first letter has been sent to me notifying me that there was a recall on the passenger side airbag. I have now received a letter stating that no one should ride in my passenger seat due to the recall.
Takata recall I get a letter every year that there is a recall but that the "remedy" is not available. There is no projection of when my remedy will be available. Meanwhile my vehicle has lower resale value, is getting older and I remain at risk.
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
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.
An extremely common problem with many vehicles is clouding of the plastic lenses over headlights. This problem is exceedingly severely bad on the mazdaspeed 6. The clouding cannot be repaired via headlight restoration kits as once it's removed, it comes back even worse after.
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.
