This week, a California federal jury has ordered General Motors (GM) to pay over $102.6 million to three different classes of GM vehicle owners. Plaintiffs of a suit filed in 2016 accuse the Michigan-based automaker of knowingly selling vehicles with serious engine defects.

GM drivers say that the manufacturer hid a glaring engine defect that causes excessive oil consumption in certain GM vehicle models. The fault mainly lies in the automaker’s Vortex 5.3-liter V8 engine, which has been installed in thousands of GM trucks and SUVs.

The suit alleges that GM was aware of a defect in the piston rings of affected vehicles that could result in irregular oil consumption. Excessive oil consumption is a serious issue that can result in stalling, internal engine damage, or premature engine breakdowns in these vehicles.

Jurors ultimately decided that GM had breached its implied warranty of merchantability to California plaintiffs; its implied warranty of merchantability to North Carolina plaintiffs; and the provisions of the Idaho Consumer Protection Act.  The settlement affects approximately 38,000 GM drivers from California, North Carolina, and Idaho. Each vehicle owner included in the class-action lawsuit will receive approximately $2,700 from the final settlement.

GMC Oil Consumption Recall Overview

The 2016 suit claims that internal documents from GM show that the automaker was aware of the engine problem as early as 2010. Over the next four years, GM responded with poor, ineffective remedies to the issue and continued to build new engines and cars. The company does not have an official remedy for the problem, nor has it issued any recalls.

GM is currently contesting the 2022 settlement. The company says that it does not believe the verdict is supported by any evidence presented during the trial. GM is seeking post-trial relief and has plans to appeal the multimillion-dollar verdict. Class action lawsuits involving similar concerns have been previously dismissed in Ohio, Virginia, and Washington.

Last month in a separate GM oil consumption lawsuit filed against GM in Georgia, a federal judge denied GM the motion to dismiss claims that it had manufactured defective engines.

GMC Terrain oil consumption recall

2014-2017 GMC Terrain SUVs and 2014-2017 Chevrolet Equinox vehicles are not included in the latest GMC oil consumption lawsuit payout however, these GM models are also known for irregular oil consumption problems. Although GM has not issued any official recall for excessive oil consumption issues in either vehicle, the automaker has issued extended coverage to owners and lessees of certain Equinox and Terrain vehicles. The special coverage offers coverage for engine problems resulting from excessive piston ring wear.

Is it possible to fix my GMC’s oil consumption issue?

It does not appear that GM has a fix for the oil consumption issue. Reportedly, an engineer for GM testified during the trial that the manufacturer had developed a cleaning remedy that could have been a potential fix for the oil consumption issue but that it was ineffective. This led GM employees and engineers to recommend that the company make changes to the piston ring design. These design changes did not fix the problem either, oil consumption issues continued in vehicles produced following these changes.

Is excessive oil consumption covered under warranty?

This issue may not be covered under the GM warranty. Several drivers report that they have had to pay for engine repairs entirely out-of-pocket because GM refused to cover the costs of these specific repairs.

Which GM Models are affected?

The following GM models may be affected:

  • Chevrolet Avalanche
  • Chevrolet Equinox
  • Chevrolet Impala
  • Chevrolet Silverado
  • Chevrolet Suburban
  • GMC Sierra
  • GMC Terrain
  • GMC Yukon
  • GMC Yukon XL

The lawsuit that concluded this week also includes trucks and SUVS sold with Generation IV Vortec 5300 LC9 engines.

Note that although 2014-2017 Chevrolet Equinox and 2014-2017 GMC Terrain SUVs may also have oil consumption issues, these vehicles are equipped with 2.4-L Ecotec engines and are thus excluded from the class-action settlement. Three separate lawsuits against GM allege that the Equinox and Terrain, like other vehicles listed above, may have a manufacturing defect in their piston rings. Owners and lessees of these vehicles may be eligible to pursue individual lemon law claims.

Can you file a GM Lemon Lawsuit?

If your vehicle is not included as part of the class action lawsuit, you may still move forward with an individual lemon law claim against General Motors.

The settlement in the 2016 lawsuit will be divided among 38,000 members, with each owner or lessee receiving only $2,700. That amount likely cannot cover the total repair costs that these drivers may have paid for out-of-pocket.

If your vehicle is excluded from this latest settlement, your case may qualify for lemon law compensation in the form of a refund, replacement vehicle, or cash compensation.  To determine if you qualify, we recommend that you speak with a reputable lemon law attorney in your area as soon as possible.
