While driving a 2018 Audi SQ5 with the EA839 3.0T engine, a coolant warning light activated and engine temperatures began rising to 210-215°F. The vehicle was pulled over immediately. Upon inspection the coolant reservoir was found to be nearly empty with dried coolant residue on the exterior indicating an active leak. The vehicle was towed to an authorized Audi dealer who confirmed via multi-point inspection that the water pump, shut off valve, and vacuum system require replacement due to coolant leakage, with a repair estimate of $5,324.87. This is a known defect in the EA839 engine platform. Audi has issued multiple Technical Service Bulletins on this issue and is currently named in active federal class action lawsuit Larr et al. v. Volkswagen Group of America, Case No. 2:26-cv-05678. The vehicle was confirmed by the authorized dealer and the component is available for inspection.
