2007 Mazda CX-7 tires problems

Tl* the contact owns a 2007 mazda cx7. The edge of the driver-side door is curved and sharp; therefore when attempting to enter the vehicle he sustained a laceration. Also the visor on top of the sun roof fractured. The tires tread began wearing abnormally starting at 26,000 miles. The dealer nor the manufacturer have been notified of the failure. The failure mileage 26,000.

I have a 2007 mazda cx-7. It is a very beautiful car but also has tons of problems. At 15000 miles it was leaking oil and they replace the engine gaskets. Then later was also leaking oil. Was told by the dealer that it was not. Took it to someone else who said it was leaking from the timing chain. Mazda resealed it. Since then my car doesn't shift properly going up and down hills. My air conditioner is hot and makes a funny sound. My car has loss of power and sound like a diesel.
