Volkswagen's 2.0-liter turbo engine has come under fire due to problems alleged to have caused serious malfunctions among some users. In a class-action lawsuit filed in New Jersey courts, it is argued that defective piston rings caused excessive oil leakage into the combustion chambers. The complaint attributes this oil leakage to a jammed crankcase vent valve, leading to increased pressure and damage to the gasket and surrounding components.
It is stated that as a result of this chain reaction, dangerous problems such as cracked oil sumps, dirty spark plugs, and erratic engine operation and difficulty accelerating can occur. AFFECTED MODELS The statements under this heading point out that VW Tiguan, Atlas, Passat and Audi Q3, Q5, Q7 models produced between 2018 and 2026 are included in this class action lawsuit.
The plaintiffs argue that warranty services are ineffective, claiming that faulty parts are replaced with identical defective parts at authorized service centers. These claims aim to support the assertion that the warranty increases the maintenance and repair costs for vehicle owners.
