I bought my car march 6, 2003. In may of 2003 it started making a howling noise when turning left at low speeds or into a parking space. I have brought it in 4 times and they cannot find the noise. For the last 2 months my transmission has been hesitating at around 25-35 MPH. It is like it doesn't know what gear to shift into and when it does it makes a loud clunking noise and my car jerks forward. I have had it in twice for that and they cannot find the source of that either.

I have a 2003 mazda 6s with the automatic transmission. Since it was new it made noises and did not feel as though it was shifting right. It hangs between gears and there is a considerable hesitation when accelerating. Have had it to the dealer four times, went through the lemon law, and even though with the tech in the car I got the car to glitch and hang, he indicated normal operation. He insisted that the switch to synthetic transmission fluid is the culprit; however, quality of operation has decreased significantly since the dealer flushed the fluid and went back to conventional transmission fluid.

Was left stranded when check engine light and at light came on. Car would not accelerate above 20 MPH and had some jerking. Had car towed in. Service dept replaced throttle body and sensor. Car still repeatedly has a jerk/hesitation when holding steady between the speeds of 40mph and 50mph. Have brought the car in three times for the jerking/hesitation and the service mechanic does not know what else to do. They tried redownloading the computer which worked for about 1 week and then the jerking/hesitation proceeded. My service dept has spoken to customer service of california and they say they have not heard of any of these problems with any other mazda 6's and they have no idea what it is. I have also experienced a water leak in my vehicle about a month after I bought it which flooded my whole passenger side. Carpet had to be replaced. My brakes have a squeaky, grinding noise when turning. My back seat seams are coming unsewed. Will have to get the fabric replaced. My question is, "what's next?" I have already recieved legal advice and my lawyer thinks I have a pretty good case. If nothing can be done, then why not replace the vehicle. I am fed up with spending my time at the mazda dealership. I bought a new vechicle to stay away from mechanical difficulities.
