GM 5.3 Liter V8 Vortec Defective Engine
The lawyers at Pendley, Baudin & Coffin are investigating and litigating cases against General Motors (GM) concerning claims that its Generation IV 5.3 Liter V8 Vortec 5300 engine installed in 11 different truck and SUV models from 2010-2013, is defective and causes internal damage to the engine.
The affected models are as follows:
- 2010-2013 Chevrolet Avalanche
- 2010-2013 Chevrolet Express 1500
- 2010-2013 Chevrolet Silverado 1500
- 2010-2013 Chevrolet Suburban
- 2010-2013 Chevrolet Tahoe
- 2010-2013 Chevrolet Colorado
- 2010-2013 GMC Yukon
- 2010-2013 GMC Yukon XL
- 2010-2013 GMC Sierra 1500
- 2010-2013 GMC Savana 1500
- 2010-2013 GMC Canyon
Plaintiffs allege that the faulty engine consumes oil at a rate far above industry standards, causing dangerously low oil levels and irreparable engine damage. GM's "Oil Life Monitoring System" is also blamed for the failure because it did not monitor engine oil levels properly.
All engine defects allegedly existed at the point of manufacture, and started causing problems for owners without any prior warning signs. Plaintiffs in a previously filed class action lawsuit assert that GM knew about the oil consumption problems but did not warn consumers.
The GM 5.3L oil consumption problems are linked to defective oil control piston rings that allow too much oil to enter the combustion chambers to the engine. Once the oil is consumed or accumulates, the engine begins to experience a number of serious malfunctions.
If you have owned or leased one of the below GM models, drivers should beware of power loss during acceleration and excessive exhaust smoke. If the vehicle enters "safe mode", the engine could immediately shut off or run extremely poorly.
