On several models of Mazda 6's Mazda has issued a TSB for the problem which is a defective throttle position sensor. I have read thousands of complaints by consumers. Mazda has made a new part yet not recalled the old part. When this part fails you lose all acceleration power to the vehicle. The way to reset this is to turn off the motor and turn it right back on. I was driving on a two-lane highway crossed over the broken double yellow line to pass another vehicle when this defective part failed and I lost all acceleration. Thankfully, I had just enough time to be able to allow the same car I was passing to pass me and I pulled off the roadway. The car worked fine for the rest of that trip it occurred again on the freeway in the fast lane. I contacted Mazda corporate customer care they advised me that they were aware of the issue but had not issued a recall at this time.
My car has had 4 recalls. I purchased the car in 2006 not knowing that parts had been recalled 3 times. I recently fixed a problem in my car that I feel make have had something to do with recall #3 , the fuel sender unit.
I purchased my 2003 Mazda 6s in October 2003. Since I have owned the car I gets poor gas mileage on it (about 16-18 miles per gallon). I do plenty of city driving but I still feel that this is not adequate. Even when I drive on the highway the gas mileage averages poorly. There is also a smell coming from the exhaust when vehicle is in motion. The vehicle also rev's up higher before switching from lower gears to higher gears. I do not 'jack rabbit' start or stop the vehicle. There is also alot of brake dust on the rims of the front wheels. Acceleration is very poor. There is also a jerk when the vehicle switches from first gear to second. Don't get me wrong I love the way the vehicle looks, which is the main reason why I bought the vehicle, but the overall quality has turned out to be much poorer than I had expected.
