General Motors has had its share of lawsuits over the years, and the latest involves some of its best-selling trucks and SUVs. In fact, the newest lawsuit against GM alleges the engines in vehicles such as the Chevy Silverado were “engineered to fail” from the beginning, that the automaker knew about it, and that it refuses to acknowledge or fix the issue.
With so many owners complaining about the same faulty engine, it appears GM’s time to ignore its mistake has run out.
GM faces another lawsuit over fuel consumption
GM is facing a new proposed class-action lawsuit over the engines in some of its most popular models. This complaint contends some Vortec motors used in GM SUVs and trucks, such as the Chevy Silverado, are plagued with oil consumption problems owing to the defective engine. Owners contend that the fourth-generation Vortec engine was designed with flawed piston rings, leading to issues with oil consumption and even the potential for engine fire, according to CarComplaints.com.
The engine in question is the 5.3-liter Vortec in the following GM models:
- 2010-2014 Chevrolet Avalanche
- 2010-2013 Chevrolet Silverado
- 2010-2014 Chevrolet Suburban
- 2010-2014 Chevrolet Tahoe
- 2010-2013 GMC Sierra
- 2010-2014 GMC Yukon and Yukon XL
GM’s faulty engine and what you need to know about the lawsuit
According to the proposed class-action complaint, GM intentionally created a defective engine that was “built to fail” from the beginning. The Vortec 5300 was designed with defective piston rings, which fail to maintain oil in the crankcase and ultimately compel the engine to consume excessive oil.
The plaintiffs also claim the engine’s fuel-management system contributes to the problem. Owners say it inhibits the oil pressure gauge, so oil levels fall low. Additionally, drivers are not informed of the low levels. Some also report the problem with oil levels destroying the spark plugs, causing their vehicles to operate badly, misfire, and even stop down.
What’s more, the plaintiffs and experts believe GM has known about the oil consumption concerns since its 2007 model-year vehicles were initially offered. The lawsuit alleges the Vortec engine’s engineering problems consume too much oil, causing low oil levels, inadequate lubrication, and, ultimately, internal damage that results in huge repair costs. When confronted with concerns, GM has declined to take accountability for these repairs.
Filed with the U.S. General Motors LLC is being sued by Airko, Inc., et al., in the Northern District of Ohio’s Cleveland Division. The lawsuit alleges that GM violated both its implied warranty and Ohio’s Consumer Sales Practices Act.
