A lawsuit says the 2.4L Ecotec engine in the 2010-2017 Equinox burns too much oil, knocks incessantly, has defective spark plugs, and is pre-disposed to timing chain issues that can lead to complete engine failure. But wait, there’s more…
A lawsuit says defective piston rings have been causing overheating and oil consumption issues in Equinox and Terrain vehicles since 2010.
The allegedly faulty engines cause too much oil to enter the combustion chambers, something General Motors has allegedly known about since before 2010. The plaintiffs claim defective piston rings, including both “compression” and “oil” rings, can't handle the high compression ratios of the engines.
It's no secret that the Equinox's 2.4-liter EcoTech engine has problems with excessive oil consumption. Now there's a lawsuit that wants Chevy to do something about it.
