Consumer Description

Due to a leak in the rear axle that is connected to the differential, it caused the entire differential to fail. The bearing within the differential completely failed due to contaminated oil. The Q8s are known to have this occur but only in year models 2020-2022. My Q8 is a 2019 and Audi is aware of these issues given technical service bulletins available but doesnt want to take responsibility as this may be a continuing manufacturing issue arising. My vehicle only has 65k miles on it and Audi admits this is rare. Due to a misdiagnosis in June of 2025 (oil leak), Audi of Seaside Monterey caused the complete failure of the differential in December of 2025 by not doing a deeper diagnosis earlier to resolve the catastrophic failure. This is a safety concern and very expensive. A new differential costs $12k which has been expected to pay with no accountability. I am currently in an active case with Audi Seaside and the BAR to come to a resolution.
