Hard knocking noise occurs when attempting to turn the vehicle. Dealership has made multiple failed repair attempts to fix the vehicle (a motor mount, rear sway bar bushings, front strut bar bushings, front sway bar, stabilizer plate, control rod, upper strut bearing and mount) as drivability and handling issues have become worse. The dealership recently determined that the vehicle has a bent lower A-arm which is of no fault to external influence. As the vehicle is now out of warranty the manufacturer is refusing to fix the vehicle. The defect in the lower A-arm is as a result of a failure in material. The front end geometry is now severely out phase by 30 degrees (per the dealership) which can cause undue stress to the lower ball joint causing premature breakage. The result of the lower A-arm separating from the spindle can cause an accident. The vehicle needs a new A-arm and possibly other related components. Tw*

2007 Mazda 3 excessive premature tire wear. At 30,000 miles I see that the front tires are worn to the point of steel band visible and sticking out. Inspection at 25,000 miles dealer said there was wear but not critical. The tread is separating and I am replacing tires immediately. I have learned that front suspension has excessive negative camber causing this.

I have had the dealer replace front end parts 2 times. First the front hub bearings. Then they had to replace the intermediate shaft also part of the front end. The car is 2007 with 37,000 miles. I have other cars with over 100,000 miles and never had to replace any of these parts.
