A class action lawsuit has been filed in a California federal court against General Motors. Installed in almost a dozen GM model vehicles (listed below), the Generation IV 5.3 Liter V8 Vortec 5300 engine rapidly consumes oil at a rate that greatly exceeds industry standards. This excessive oil consumption results in low oil levels and internal engine damage.
The oil consumption defect is caused by low-tension oil control rings that GM installed within its Generation IV 5.3-Liter V8 Vortec 5300 passenger engines. The low-tension oil rings are incompatible with these engines as they allow an excessive amount of engine oil to enter the engine’s combustion chambers – where it is consumed or accumulates – resulting in oil loss.
GM offered the defective 5.3-liter engines in the following vehicles (the “Class Vehicles”):
• 2010-2013 Chevrolet Avalanche
• 2010-2012 Chevrolet Colorado
• 2010-2013 Chevrolet Express 1500
• 2010-2013 Chevrolet Silverado 1500
• 2010-2013 Chevrolet Suburban
• 2010-2013 Chevrolet Tahoe
• 2010-2013 GMC Canyon
• 2010-2013 GMC Savana 1500
• 2010-2013 GMC Sierra 1500
• 2010-2013 GMC Yukon
• 2010-2013 GMC Yukon XL
GM’s “Oil Life Monitoring System,” which is supposed to alert drivers when it is time for an oil change, makes the problem worse because it does not properly monitor the engine oil level. As the oil ring defect rapidly depletes the engine’s oil reserves, the Oil Life Monitoring System dangerously encourages drivers to travel farther than the engine can safely handle due to inadequate oil levels.
Beginning with its 2014 models, GM began installing a materially redesigned Generation V 5.3 Liter V8 Vortec 5300 engine, which was designed to remedy the excessive oil consumption problem. The redesigned engine abandoned the low-tension oil control ring engineering failure and returned to the use of standard tension oil rings. However, despite knowing that vehicles equipped with faulty 5.3-liter engines remained on the road, GM has done nothing to alert owners and lessees that their vehicles may be unreliable and unsafe.
