“I currently own a Mazda 6 (2006) which I acquire o march 13, 2007. Since february 15, 2007 my car started to stalls and shut off. I had taken my vehicle back to the dealer (Mazda jim click) for repairs since the problem arise. When I bought the vehicle I also paid for an extended warranty platinum (pas). The extended warranty is for 72 months or 100,000 miles which ever occurred first which include any mechanical or electronic problems in the vehicle. The vehicle had been in the services department for repairs five different occasions. …”
NHTSA complaint #10239908, filed 2008-08, 37,000 miles“I leased my fully loaded 2006 Mazda a6 back in december of 2005. Ever since then, I have had trouble with the car. First, the driver side window was not going down. A few days after I bought the car, I realized that the turbo kept giving out on me. Then I came across a huge dilemma, where the limited slip differential, drive shaft, and all the bolts and hinges had to be replaced because of a bolt which was not torque enough. Then, the brakes kept making an annoying noise even without the brakes applied at low and high speeds. …”
NHTSA complaint #10162385, filed 2006-07, 12,000 miles“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. …”
NHTSA complaint #10178613, filed 2007-01, 3,400 miles“The check engine light comes on. I had the code checked and it is the cooling sensor. The vehicle is not overheating and light will go off for a short time and then come on again.”
NHTSA complaint #10549877, filed 2013-10, 60,000 miles“Engine power decreases substantially going uphill when you push accelerator. Even after the recall item was fixed (reprogrammed computer), it still does it, especially on other then 93 octane gas which is not always available. When merging into traffic, had a few close calls with accidents.”
