Loud Knock Driver's Side
My 2014 CX-9 has a strange knock coming from the drivers side. Almost like somebody hit the car with a rock.
It usually occurs toward the back seat area, occasionally toward the front. The loud knock occurs randomly. Sometime VERY loud, sometimes not so loud. Usually when the car is moving, but sometimes when at a dead stop with the engine running.
This has been going on for about three months now.
My mechanic checked it out but didn't hear the sound. However, he confirmed the car is driving well.
Has anybody ever experienced this? It's driving me crazy and I'm about ready to sell the car.
Thanks in advance for any ideas.
