Audi doesn't care for the customer safety

The brand AUDI is good but have been supplied defective car from the AUDI dealer in Rajkot and now having lots of problems in it which is related to the safety to which they are ignoring and neither resolving. Steering assembly have been replaced which was defective, as of now suspension is found defective due to which the tyre has become chubby, breaking has lost nearly 60 % of its working efficiency which can cause an accident anytime and can cause death. Even after replacing the steering assembly the steering is making noise on making turns which can break the parts and also the steering has become so hard that while driving AUDI Q7 i feel that am driving a truck instead of a luxury SUV.
