Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Mazda MAZDA6 Owner Comments

problem #6

  • 300,000 miles


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, motor mounts $900, transmission $2400-$4800, brakes $400, and the cost goes on. (lemon).

The clutch has begun to fail. The dealer indicated that it would be five months before one became available. The clutch, starter, cd changer, and panel cover were defective. There was rust on the door sashes. There was a smell from the exhaust that entered the vehicle, there were vibrations and rattles in the door, which had been adjusted. There were problems with the master cylinder and the leaking fuel sender unit in the gas tank. The starter would grind and the clutch shuddered.

On July 4th weekend it started making a clicking noise when you drive it 65mph. The dealership decided it was a defective catalytic conveter. I had to drive it 3 weeks making this noise.then the check engine light came on.then I got a recall for the brake system. Now it's Aug. 8 I am still in a rental car. All I want is for the dealership to take back the car, cancel the loan & go our seperate ways.

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.

Within eight months of owning the vehicle, there were other problems such as a defective cd player, a persistent sulfurous smell coming from the exhaust which entered the vehicle, a defective fuse access cover and the removal of the interior driver and passenger door panels to remedy a rattling noise when driving.

There is an odor coming from the exhaust. I have taken the car to the dealer two times for this, and they told me it was the gas I was buying. So I started buying gas out of town for a while, the odor continues. I have 12,000 miles on the car, and the odor keeps getting progressively worse. But the dealer keeps telling me it is the gas, and offers no help.
