NHTSA Complaint #11457993 — 2017 AUDI A4

My 2017 Audi A4 Quattro is now five years old. There is only 26,000 miles on the vehicle. Mostly local miles. I noticed drops of red fluid on the garage floor under the engine compartment. My mechanic investigated and found the issue to be leaking coolant from the thermostat/pump housing. It is obvious that the leak has been occurring for awhile as there is dried white residue all around this area. The engine cover under the engine compartment was all wet with coolant. The coolant reservoir was also low. The car's information system did not indicate an issue, but I am sure it would have eventually (at probably a very inconvenient time and location ! ). I've noticed several other Audi owners complain about this same issue. This will no doubt be an expensive repair which is totally unacceptable for a car like this with such low mileage.
