While driving on town roads and around a traffic circle a loud noise was heard from the right hand side of the vehicle. I attempted to pull into a nearby gas station but the vehicle would not steer to the left enough to enter the parking lot. I managed to pull into another lot a short distance down the street on the right hand side. I inspected the under side of the vehicle and discovered the front sub-frame had rusted through to the point of failure. This failure allowed the complete front left wheel/suspension assembly to move about freely under the car.

Heard a knock while driving (as though hitting pothole). Next day steering column felt loose, breaks seemed worn and sound on sharp turns. Later that day while driving in city, went over a normal dip in the road and heard a crack/louder knock. Wheel turned to the left, even though driving straight. When applying brakes, wheel now turned to the right. Pulled aside and ran over curb as brakes were not as effective. Initial diagnosis: Brakes and bearings need repair (although these were replaced less than 5 months ago). Next diagnosis: Subframe psg. Side completely rotted and cracked. Will take a month to repair [rental provided]. note- the past 6 months I've had other issues including: Electrical (fuse for radio/locks/int lights keeps breaking; after 1.5 hour diagnostic cause still unknown. Chose to replace fuse as needed- weekly to monthly); 3 tires have gone (even though 2 were fairly new; needed alignment); brakes and bearings twice. Could be regular wear and tear or could be related.

I was on a city street travelling around 35 mph. While approaching a stop light and applying the brakes the car suddenly started pulling to the right and almost pulled the entire vehicle into a ditch. The vehicle came to a stop at the edge of the grass. I pulled the vehicle over further to avoid traffic and noticed the right tire was now touching the wheel well. After having the vehicle towed the mechanic informed me that there was extensive corrosion underneath the vehicle which had led to the failure.

Noticed a knocking noise developing in front passenger side. Took the car to a local garage to have it checked out and to get new tires and alignment. I was notified that the sub-frame was rotted out and the car was no longer safe to drive. Contacted Mazda for new sub-frame and was notified that the part has been on back order for 6 months and they had no idea when they would be available. Now I am stuck with an 8 year old car that is unsafe to drive with no hope for repair.

The contact owns a 2010 Mazda 6. upon starting the vehicle, the steering wheel became tight and extremely difficult to turn left or right. The vehicle was restarted but the failure recurred. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 60,213.

This vehicle does not track straight, even on a level road. At highway speeds (above 50 mph) it has a decided pull to the left, regardless of the lateral slope of the road. Constant clockwise pressure on the steering wheel is necessary in order to keep vehicle from drifting in a leftward direction. If driver attention is diverted for only an instant the vehicle is likely to partially intrude into the lane to the left, which on an undivided highway could be an oncoming traffic lane (hence the safety issue). I called this to the attention of my Mazda dealer's service department at least twice within the first year after purchase (January 2010). Their answer was no answer--they could not find anything wrong mechanically and there were no bulletins from Mazda on the subject. They verified the alignment and rotated the tires left to right, but neither of these solved the problem. Nearly five years later the problem still exists and seems even more pronounced than it was originally. A recent check with the dealer indicated that there is still nothing from Mazda. Possibly it is a defect that applies only to my car and not in general to that model, but I have no way of determining that at this point.

The rotors are warped after less then 30K miles. This causes the car to shimmy when braking at any appreciable speed (any speed over 40mph). Took car to dealer and they claim it is not covered under the warranty as it is "normal wear and tear". called Mazda and they too refused to fix the problem under the warranty.
