the water pump failed on my 2020 Audi SQ 8 at approximately 42K miles. before diagnosis the engine temperate gauge repeatedly fluctuated while driving. An Audi specialist shop diagnosed the issue as a failed water pump. A failure at this mileage is premature and presents a safety concern as this could result in a catastrophic engine failure. I am requesting that NTHSA evaluate whether similar failures involving the 4.0 liter twin-turbo Audi SQ8 cooling system.
