Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
Complaints for the 2019 Audi A4 are spread thinly across several unrelated systems, with no single issue drawing a clear cluster of reports. Individual owners describe a range of distinct experiences: one report involves sudden unintended acceleration at low speed with simultaneous brake failure while parking, another describes a fuel smell inside the cabin following a crash that damaged the fuel tank and fuel line, and a third involves a turbocharger wastegate actuator failure at highway speeds that caused a significant loss of engine power and disabled cruise control. A passenger-side motor mount leaking at around 50,000 miles appears in one report, and a malfunctioning SOS alert system is noted in another. None of these issues appear across multiple complaints in this dataset, so no recurring pattern stands out.
