NHTSA Complaint #11693419 — 2015 VOLKSWAGEN PASSAT

My vehicle is a MY2015 Passat TDI SEL with the EA288 (CVCA) diesel engine. Water Pump Failure Occurred at 99488 miles. Leaking coolant from underneath the engine and the expansion tank bottle became empty. Vehicle was parked after a quick 8 min drive to work from home in the morning (~8:45AM) and when I came back at 12PM around 1 quart of coolant had leaked out. Luckily I was not on the freeway or driving the vehicle where it would ride on its torque curve increasing probability of catastrophic failures even after there are usually software induced engine protection derates in place. Official service interval for water pump and timing belt on this engine is 130000 miles but there have been numerous field incidents of pre-mature water pump failures which can be very expensive to fix (~2500 USD). Volkswagen/Audi already have a class action lawsuit against them on their 2.0 TFSI (EA888) water pump failures and I'm wondering why their MY2015 2.0 TDI (EA288) diesel engine has not been investigated for the same. This engine was only available in certain MY2015 VW/Audi vehicles but just because the cumulative number of vehicles with this engine are lower does not mean that it shouldn't be investigated for a very similar manufacturing/design defect of the water pump. I would strongly urge NHTSA to do a similar investigation on this 2.0 TDI engine and hold the manufacturer accountable.
