When i make a left turn, there is a knocking sound. And a humming sound from the engine, louder than normal and when i turn the AC on it sounds like something knocking or catching like a fan blade fitting something.
Took the car to the dealer and told them about these and they claim to have fixed them. but they haven't.
My car has 76000 miles.
My car has an automatic transmission.
Hello - the "knocking sound when turning left" is most likely a failing outer CV joint on the left, or driver side, of the vehicle. Turning, while accelerating, is hard on these joints. The CV joint/axle assembly will need to be replaced. the noise you indicate that arises when you turn on the air conditioning is most likely a worn AC compressor. It may run for a while, but more likely, it will fail fairly soon. I would recommend replacement of the CV joint/axle by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs. An "under-the-hood inspection" is also in order for the noisy AC compressor.
