Automatic Transmission problems of the 2003 Mazda MAZDA6

2003 Mazda6 6. 0 atx - car suddenly loses power while accelerating. The engine revs but no power to wheels. I have contacted local dealer without any resoulution to why this is occuring. Upon a brief internet search I find this is not an isolated case. I have noticed it happens more often with ac unit on.

Engine needed to be replaced twice within less than 5 1/2 yrs. Transmission needed to be replaced within 6yrs. Brakes needed to be replaced every year and a half. Interior cheaply made. All part on this vehicle are plastic and brake very easy. Motor mounts needed to be replace within 4 yrs. This vehicle is a owners nightmare . I would never recommended anyone to purchase this car. Repairs cost more than the car is worth. Engine repair $6000. 00, motor mounts $900, transmission $2400-$4800, brakes $400, and the cost goes on. (lemon).

My car has had all of it's routine maintenance done. At 30k I had to replace the transmission at 20 I had to replace the alternator. At 60k I have had to replace the transmission again! at 60k I had to replace a transaxle something or another . Now at 66k it is doing all of the same things that it was doing before the transmissions went out, and it's because "I need a new air filter, spark plugs, and fuel filter" the car jerks very hard when slowing down on the freeway the rpm race, like it won't gear down. When I put it in park it's as if I am pressing the gas pedal down and revving the engine. But the car is in park, and there is no pressure on the gas pedal what so ever! I hate this car, and recommend no one to buy one! I will be voicing my opinion of the car in the car windows, and telling everyone I know about the poor quality of this car. You would think that paying 27k for a vehicle that it would last!.

Violent shifting from 1st to 2nd gear in the Mazda6s with automatic transmission. Feels as if the car has been hit by another vehicle from the rear. Front tires momentarily lose traction and chirp sometimes. These violent shifts only happen during mild accelleration.

The "new" vehicle had 900 unexplained mile on it upon purchase. Within 4 months the check engine light came on and the vehicle kicks back when changing gears. Took to dealer in pennsylvania, was advised that needed knock sensor replaced, but they did not have part. Took the vehicle to dealer in virginia, did not look at it, although I told them what other dealership said, and told them there was a recall on it. Took to different dealership and was advised that there are 2 recalls, and they were fixed. Now the fan races minutes after the vehicle is off. Also, the vehicle seems to be lacking in power despite the engine is 220 horse power.

While driving at any speed consumer heard a loud knocking noise coming from the rear. Consumer was able to maintain control of the vehicle, and drove it to dealer for inspection. However, mechanic could not duplicate the problem.

The engine light and transmission light indicated a problem to me, as well as the car jerking upon acceleration. After taking the car to the dealer for service it was determined that knock sensor had malfunctioned. Since the first visit to the dealership for service regarding this problem, it has happened 5 times. I have contacted my dealer and the manufacturer and am still dealing with this issue. My dealer has made no attempt to rectify the situation other than replacing the engine sensor over and over. The car was out of commision for over a week each time. I have gone to the dealer asking for their help in contacting Mazda about a new engine and or car and they are completly uncooperative.
