In addition, owners allege the SUVs don't have adequate warning systems to protect the vehicles from negative effects of oil consumption problems.
General Motors LLC.Ī Chevy Equinox Ecotec engine lawsuit alleges the piston rings, spray jets and PCV systems all contribute to oil consumption and engine damage. Settlement Ellen Berman and Dayana Guach, et al., v.Plaintiffs Patrick Sanchez, Mark Stauber, Sally Stauber, Jacob Ross-Demmin and Jennifer Herrington filed the proposed class-action lawsuit about 2010-2017 Chevrolet Equinox and GMC Terrain vehicles with EcoTech 2.4-liter engines. General Motors LLC.Ī GM oil consumption settlement has been approved by a federal judge for customers of 2010-2013 Chevrolet Equinox and GMC Terrain SUVs equipped with 2.4-liter Ecotec engines. Click on the lawsuit for more information and to see if you're eligible to receive any potential settlements. Many times these are class-action suits that look to cover a group of owners in a particular area. Lawsuits about this problem have already been filed in court. The LAF and LAE variants run from 2010 to 2017 and appear to have oil consumption problems. Learn more about the settlement details on. Although the settlement hit a snag before finally being approved by a judge in late 2019.
Those suits were consolidated and settled in May of 2019. In the 2018 calendar year, GM faced three class-action lawsuits that all essentially followed the same pattern.
2016 EQUINOX PCV VALVE PROBLEMS SERIES
A Series of Lawsuits ∞Īs you might imagine owners of all other model years with the same exact problem were less than thrilled. The coverage included any costs needed to replace the engine's 4 piston assemblues which is a time-consuming and expensive job. Originally for 2011 Equinox owners, the coverage eventually extended the warranty to 7.5 years / 120,000 miles for 2010-2012 owners. " Some 2011 model year Chevrolet Equinox and GMC Terrain vehicles, equipped with a 2.4L engine, may exhibit excessive engine oil consumption (less than 2,000 miles per quart of engine oil), due to piston ring wear." Special coverage adjustment increases protections for 2011-2012 Equinox owners ∞Īs complaints continued to pour in, GM offered a special coverage adjustment in May of 2016.
2016 EQUINOX PCV VALVE PROBLEMS SOFTWARE
While previous bulletins only offered software updates to reduce the recommended oil change intervals, TSB 15285C acknowledged oil consumption as an issue for the 2.4L Ecotec LAF engine due to worn out piston rings. TSB 15285C was released in March of 2016 and offered a real breakthrough towards addressing this problem. PCV plays an important role in engine efficiency, as it draws gas out of the crankcase, sending it through the intake manifold and back into the combustion chamber where it can be used.īut the Ecotec's PCV may be vacuuming more than just gas vapors as it also allegedly pulls oil off the valve trains and into the intake systems where it gets burned off. Faulty positive crankcase ventilation ( PCV) system ∞Īnd because that's not enough, it's widely believed that the Ecotec has a defect in its PCV system. This allows even more oil than normal to sneak past and faulty or worn rings into the combustion chamber. Ecotec oil control rings when the jets start sprayingīut the jets spray pressurized oil directly into the cylinders where frail oil rings are already struggling to keep oil in the crankcase. Less fricition means longer durability and increased performance. To make matters worse, the Ecotec engine uses oil cooling jets to reduce piston temperatures. Spray jets overload the already weak rings ∞ Those gaps allow oil to sneak past and burn up in the combustion chamber. GM opted to go with a thinner, low-tension oil ring for the 2.4L Ecotec engine.īut the oil control rings GM chose are way too thin and wear down quickly allowing gaps to form in the ring's coating. As the piston moves up and down, the oil control ring scrapes oil off the cylinder walls and prevents it from exiting the crankcase. That last responsibility falls on the oil control ring which is found at the bottom of the control ring stack. Oil control rings that are too thin ∞Įach piston has multiple control rings to maintain compression, transfer heat, and keep oil out of the combustion chamber. The new design relied heavily on low-tension oil control rings, spray jets, and a positive crankcase ventilation system to lower fricition, increase efficiency, and boost performance. GM switched to direct-injection for the 2.4L Ecotec engine in some 2010 models.
