Some Acura MDX owners report experiencing drivetrain noise during deceleration, particularly a rotation-based sound emanating from the middle of the vehicle. This issue may be attributed to several factors, including the drive shaft and rear differential, both of which can contribute to noise during this phase of driving. Additionally, worn wheel bearings are known to produce a whining or grinding noise that becomes more pronounced when the gas is released. To effectively address these concerns, it is advisable for owners to have a professional mechanic inspect these components to accurately diagnose the source of the noise and carry out any necessary repairs for optimal vehicle performance.
