Two Subaru owners have sued the automaker and are seeking class action status, alleging that some Subaru models burn excess oil that can result in engine failure while being driven, the Associated Press reported.

The lawsuit says piston rings in certain vehicles wear out too quickly and oil consumption "can cause engine failure while the Class Vehicles are in operation at any time and under any driving condition or speed."

The Subaru vehicles allegedly plagued by the issue are the 2011-'14 Forester 2.5-liter, 2013 Legacy 2.5-liter, 2013 Outback 2.5-liter, 2012-'13 Impreza 2-liter and 2013 XV Crosstek 2-liter. The lawsuit also cites "violations of the state's consumer fraud act, breach of express warranty and other violations," according to the AP.

The two plaintiffs are Keith Yaeger, of Escondido, Calif., and Michael Shuler, of Lakeland, Fl.

Subaru is aware of the lawsuit but believes its vehicles do not consume excessive amounts of oil, the automaker has said in a statement.

The lawsuit alleges that owners would not purchase these Subaru vehicles if they realized that they would have to "constantly replenish (and pay for) engine oil ... at an unreasonably rapid pace," USA TODAY reported.

While no injuries or collisions are listed in connection with the problem, the suit says that engines can fail "at any time and under any driving condition or speed." It also includes copies of complaints by other Subaru owners to federal regulators.

"Following an extensive investigation, we now look forward to litigating the case," said Matthew Schelkopf, a Haverford, Penn.-based attorney representing the two involved Subaru owners, as quoted by USA TODAY.
