The Ford F-150 is the target of a new class action lawsuit due to alleged defects in the 5.0-litre “Coyote” V8 engine that are said to result in excessive oil consumption.
The lawsuit was filed in the Ontario Superior Court of Justice by McKenzie Lake Lawyers on behalf of William Kennedy, the owner of a 2018 F-150. It covers all 2018-2020 Ford F-150 models equipped with said V8 engine.

Kennedy bought his truck in St. John’s, Newfoundland and Labrador in 2018 and started experiencing problems with oil consumption within a year. This includes “low oil levels, low oil pressure, engine and spark plug knock, fouled piston rings and a lack of lubrication in the engines.”
Performance is reduced and multiple engine components suffer damage which finally causes the engine to stall or fail completely, the lawsuit alleges.
So far, none of the remedies seem to fix the problem definitely. One of them is replacing the positive crankcase ventilation (PCV) valve. It’s also possible that excessive oil consumption is caused by the piston and oil rings which don't maintain enough tension to keep oil in the crankcase, thus allowing excess oil to flow into the combustion chamber and through the exhaust.
Ford has "longstanding knowledge" of the alleged defects but failed to warn F-150 customers about the Coyote V8 engine problems, according to the lawsuit. Kennedy said he wouldn't have purchased the truck if the company had warned him about the problem.
A judge in the Ontario Superior Court of Justice will now decide whether to authorize the class action lawsuit or not.
