Genesis GV70 whinging noise from rear due to differential replacement needed on Genesis GV70

Some Genesis GV70 owners report experiencing a whining noise from the rear of the vehicle, which may indicate an issue with the rear differential that could require replacement. This noise is a common concern among owners, and Genesis has issued a technical service bulletin (TSB 23-DS-004G-1) addressing rear differential noise inspection and repair for certain models, including the GV70. In some cases, if the noise is more pronounced on one side, it may be attributed to a faulty wheel bearing rather than the rear differential itself. To pinpoint the source of the noise, a driving test involving gentle acceleration and coasting at around 35 mph can be helpful. The typical solution for differential issues involves adjustments, but if these do not resolve the problem, a replacement may be necessary. It is advisable for owners experiencing this noise to have their vehicle inspected by a qualified technician to determine the exact cause and appropriate action.
