Audi Sued Over Engine Water Pump IssuesAudi (Audi)Audi has had a few things to cheer about lately, from excitement over the recent reveal of the interior of the new Audi Q9 to the brand's debut season in Formula 1. But not everything regarding the four-ringed brand is rosy these days, as a class-action lawsuit has recently been filed against the German automaker over the engines found in a swath of past models.As first reported by CarComplaints.com, the lawsuit alleges the water pumps are defective in Audi's 2.9-liter and 3.0-liter EA839 V-6s; these engines were available in nearly every Audi model on sale from the 2018 to 2024 model years. The lawsuit—Larr, et al., v. Volkswagen Group of America, Inc., et al. —has been filed in the U.S. District Court for the District of New Jersey. The plaintiffs argue that the below Audi models sold in the U.S. have the defective water pumps:2018-2024 Audi A42018-2024 Audi A52018-2024 Audi S5 Cabriolet2018-2024 Audi S5 Sportback2018-2024 Audi RS 52018-2024 Audi SQ52019-2024 Audi A62019-2024 Audi A72019-2024 Audi A82019-2024 Audi Q82019 and 2021-2024 Audi RS 5 Sportback2020-2024 Audi A6 Allroad2020-2024 Audi S62020-2024 Audi S72020-2024 Audi Q72020-2021 Audi A8 e quattro2021-2024 Audi SQ5 SportbackAdvertisementAdvertisementPlaintiffs Doug Larr and Kaelin Crawford filed the complaint after paying thousands of dollars out-of-pocket after their vehicles' water pumps failed. According to the suit, Larr purchased his 2019 Audi A6 in August 2021; then in March 2026, his independent mechanic told him that the water pump was leaking coolant and the pump, PCV valve and vacuum hose system needed to be replaced. His A6 was out of warranty at that point, so Audi would not pay for the nearly $6000 in repairs.Crawford has a similar story. He bought a new 2021 Audi SQ5 in April 2021, and in June 2024, the low coolant light came on. His mechanic told him the water pump was leaking around the PCV valve. Crawford then took the SQ5 to an Audi dealer and was quoted $2800 for the repair. The Audi had 62,000 miles on it at the time, so the 4-year/50,000-mile warranty had expired.The plaintiffs contend that Audi knew the pumps were defective since at least November 2018. They further claim that the internal water pump leak can be extremely costly, because an owner may not be aware of the issue until the engine has already suffered some damage. The EA839 engine’s water pump can reportedly allow coolant to seep into the vacuum system and other sensitive components that were never designed to handle fluid contamination; that can allegedly trigger a chain reaction of expensive problems, including overheating, vacuum system damage, and turbocharger issues.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
