Audi is facing a new class action lawsuit in the United States over alleged defects in the water pumps used in the 2.9- and 3.0-liter EA839 V6 engines. The lawsuit involves several models from the brand manufactured between 2018 and 2024.
According to the lawsuit, revealed by CarComplaints.com, components of the cooling system allegedly show premature wear in seals and internal parts, allowing coolant to leak into sensitive engine systems.
The plaintiffs claim this could cause overheating, damage to the vacuum system and even problems with the turbochargers.
The lawsuit was filed after owners reported high repair costs outside the warranty period. One of the cases cited involves a 2019 Audi A6 whose repair allegedly cost nearly US$ 6,000 after a leak affected other engine components. Another owner of a 2021 SQ5 reported expenses of thousands of dollars after the low coolant warning light came on.

The plaintiffs allege that Audi had known about the problem since at least 2018, but did not issue a recall or offer extended coverage for the affected vehicles.
In addition to the current lawsuit, issues involving water pumps and Volkswagen and Audi engines have already led to other class actions in recent years, including disputes related to EA888 engines and turbocharger failures.
