“2010 Audi S4 in the san fran bay area, after a weekend drive to the snow, found a pool of coolant under car and just med it to the dealer before warning light came on. Dealer told me it was common. No recall to be expected, isn't this illegal? I make pharmaceuticals and if I don't perform a recall this is an illegal action.”
NHTSA complaint #10376526, filed 2011-01, 13,000 miles“My car leaked a large amount of coolant noticed after it had been parked. I managed to drive it to dealer where the water pump was replaced under warranty. I was told that the plastic seal on the pump has failed with other customers and was replaced with a new metal seal.”
NHTSA complaint #10363621, filed 2010-11, 12,000 miles“2010 Audi S4 with v-6 3.0t engine. Returning home after a 7 minute drive, I was 300 ft. From my house when I received an engine message coolant low, turn off engine and check coolant. I stopped in driveway to find my water pump had burst, as with several complaints here. I knew about this problem, as more than 50 other Audi S4 owners have experienced it and it is well documented on Audi owner's forums. My car is undriveable, and will be towed to dealer tomorrow under warranty. …”
NHTSA complaint #10369263, filed 2010-12, 9,800 miles“My coolant pump blew around 10k miles. I live in boston. It was cold that morning - single digits. I started the car and heard a flapping noise. I ignored it and drove to get coffee. When the car warmed up, the flapping noise went away so I started out to my destination. About 5 miles down the road, the coolant warning light came on to shut down the engine. I pulled off the highway and turned off the engine. There was smoke coming from the engine compartment and the inside was wet. I called aaa and they towed the car to the Audi dealership. …”
NHTSA complaint #10380975, filed 2011-02, 9,809 miles“2010 Audi S4 water pump failure -- this complaint is identical to the previous two complaints surrounding this model's water pump failure. It should be noted that a near full loss of steering directly related to this failure occurred at the same time. In my case the car has been repaired, however like others who have detailed their experiences, Audi has not acknowledged this is a systemic issue for this model, nor is the repair satisfactory as the distinct odor of g-12 (g-30 in europe) is present. …”
