NHTSA Complaint #11650727 — 2019 AUDI RS 3

I first began noticing symptoms of a cooling system issue on May 23, 2024, including engine temperature fluctuations and loss of coolant, on my 2019 Audi RS3. Over time, the issue worsened, eventually requiring a full replacement of both the water pump and thermostat on January 10, 2025, at 53,981 miles. This resulted in a total out-of-pocket repair cost of $2,809.95. The symptoms included engine overheating and loss of coolant. The issue required full replacement of the water pump assembly, thermostat, coolant, and associated components. Below is a summary of the repair work performed: Thermostat replacement: $847.20 Water pump replacement: $1,725.20 Additional fluids, shop fees, taxes: $237.55 Total paid: $2,809.95 I later learned that Audi had issued a recall (NHTSA Recall No. 18V229000) for water pump failures in other Audi models with similar cooling system components and symptoms. However, my model — the 2019 RS3 — was not included in that recall, despite sharing common parts and failure patterns. Given the widespread nature of this issue and the significant cost and safety risks (overheating, possible engine failure), I believe this defect warrants investigation and possible expansion of the existing recall to include the RS3 model. Documentation and a detailed invoice are available upon request.
