Toyota — fortuner engine noise

Address:

Chandigarh, Punjab, 160019

My toyota fortuner has a knocking issue coming from the car since a month. The car was inspected 3 times and has been inspected with all the senior staff in service wing but they have till not been able to encounter the issue.
I want toyota to check this noise issue as in my first experience i was suprised that how your service advisor said that your car is fine and fit for the road. Toyota management policies and our company being leader supplier to most oems in aluminium i fail to understand that a senior service advisor is not here to examine the issue and kindly give me aaction plan for the same.

Regards

Surya
