I have trouble with my new Mazda 2 only 550km. on it. It makes a creaking/squeaking noise while going over bumps or uneven surfaces. Took it to Weber mazda (Edm. AB, Canada) and they lubricated rear passenger coil springs and still makes creaking noise. Then i took it Landmark Mazda also in Edmonton Canada and they replaced Stabilizer Bushings but still makes the same noise and getting worse. I will take to and independent Mazda Service garage on Monday. What could it be? Anyone else experiencing similar problems. Seems to be faulty bushings or stabilizer links. Its very cold -25 and colder at night and makes the creaking noise even louder.
