A GM 5.3L oil consumption lawsuit includes Generation IV Vortec 5300 LC9 engines. The plaintiffs say the engine cannot receive proper lubrication, allegedly because the piston rings fail to keep oil in the crankcase.
A General Motors Vortec class action lawsuit alleges oil consumption problems plague the vehicles because of defective piston rings. The GM Vortec class action lawsuit includes these vehicles equipped with Generation IV 5.3-Liter V8 Vortec 5300 LC9 engines.
The class action lawsuit alleges General Motors manufactured and sold vehicles that consume abnormally high quantities of oil because of numerous problems with the engines. The plaintiff claims the primary problem is the piston rings that don't hold enough tension to keep engine oil in the crankcase, resulting in low oil levels and inadequate lubrication of engine components. This eventually causes complete engine failure and a huge expense for repairs or replacements.
A General Motors fuse block class action lawsuit alleges certain GM vehicles have problems with the tension of the terminals that can cause stalled engines and other electrical malfunctions.
According to the lawsuit, more than 2 million trucks and SUVs in the U.S. share the same defective air conditioning designs and were built on a vehicle platform known as GMT K2XX.
A GM cracked dash lawsuit alleges owners can spend thousands of dollars to replace cracked dashboards and instrument panels the automaker should have recalled.
A GM air conditioner compressor and condenser lawsuit alleges the AC systems fail and cause owners and lessees to lose cold air in the vehicles and money from their bank accounts.
GM air conditioning problems are caused by condensers and discharge lines, at least according to a proposed class-action lawsuit that includes the following long list of Cadillac, Chevy and GMC trucks and SUVs.
The alleged oil consumption causes low oil levels, insufficient lubricity and engine damage due to piston rings which don't maintain enough tension to keep oil in the crankcase. In addition, the plaintiff alleges the oil life monitoring systems make the problem worse.
A/C Condenser Leaking
GM used leaky air conditioners that buckle under pressure in many 2014-2017 trucks and SUVs. Whether it's busted hoses or leaky condensors, thousands of GM owners are showing up to work with sweat stains down their back. It's such a widespr…
Shift to Park Warning Message
Leaking coolant from a cracked intake manifold gasket is an extremely common problem on most GM vehicles made from the late 90s to the mid-2000s. Most experts agree that the problem stems from GM's 'DexCool' coolant which erodes away at the…
Toss another lawsuit onto the ever-growing pile of GM Vortec oil consumption cases.
The Missouri based class-action is the latest in a series of suits saying the 5.3L Vortec engine churns through oil because of defects in the low-tension piston rings. The problem is compounded by GM's questionably designed oil life monitoring system which doesn't warn owners when oil levels get dangerously low.
In fact the system doesn't monitor oil levels at all, just the quality of the oil itself. So while the engine may be dry and on the verge of collapse, rest assured that last quart of oil is still in tip-top shape. 👍🏼…keep reading
GM allegedly cut corners by installing a fuel pump that isn’t compatible with US diesel in its larger trucks.

Acadia owners are tired of seeing a shift to park message when their gear shift lever is already in PARK.
A new lawsuit says the problem prevents owners from shutting off or locking their vehicles.
In addition to losing the ability to shut off and lock the SUVs, owners claim they must resort to all kinds of theatrics to get the SUVs to recognize they are in PARK. Drivers also say the batteries drain and GM has no clue how to fix the issues.
We’ve seen complaints about this problem in both the 2017 and 2018 model years.keep reading
A lawsuit says a failed vacuum pump in GM’s brake boosters can make the brake pedal extremely hard to push
, leading to longer stopping distances and accidents.
While investigating a rear-end collision involving the lead plaintiff ”GM told her she should read the manual to understand how the brakes worked.” Nothing says “we value our customers” like accusing them of not knowing how brakes work. GM promised to fix the plaintiff’s bumper in exchange for confidentiality. Obviously this didn’t go over well.keep reading
A lawsuit regarding the GMC Sierra’s “inadequate” headlights is still burning bright in a California court.
The plaintiffs allege GM made changes in the bulbs, assemblies and operation of the headlights … GM allegedly changed to projector-style headlights with single bulbs, smaller reflectors, two lenses each and shutters to switch between high and low beams that work from a single voltage source.
Look – if you saw one of these trucks driving in the oncoming lane at night, I wouldn’t blame you if you confused it for a pair of mopeds with weak batteries. It’s that bad.keep reading
Plaintiffs in the case regarding excessive oil consumption in GM's 5.3L Vortec 5300 engines have switched gears.
The original case was tossed out by a judge last year, but the plaintiffs were given a chance to ammend their complaints. So they've switched their focus into a potentially defective oil pressure warning system that doesn't properly monitor oil levels and can lead to early engine failure.…keep reading
The judge looking into last year's Vortec excessive oil consumption lawsuit does not seem to buying claims that the engine is defective.
The case has been tossed out.
Concerning owner-reported complaints, the judge found those owners talk about excessive oil consumption but they don't specifically say what is causing the oil consumption. As for the bulletin sent to dealerships, it doesn't say anything about the oil rings and sending the bulletin doesn't mean GM believed the Vortec engines were defective.
So ... the judge says the plaintiffs don't specifically say what's causing the problem. But in the next breath, the judge says there's no mention of the plaintiff's claims of defective oil rings in TSBs sent by GM to dealerships.
I feel like I'm taking crazy pills.…keep reading
A lawsuit has been filed on behalf of certain 2010-2013 GM owners with 5.3L V8 Vortec 5300 engines.
According to the plaintiffs, changes to the engine design allow oil to enter the combustion chamber, leading to excessive oil consumption and premature engine failure.
The lawsuit says GM 5.3L oil consumption problems are caused by defective piston rings, PVC systems and "active fuel management" (AFM) systems that cause the spark plugs to wear out prematurely and the engines to experience all kinds of malfunctions.
The problem may be due to low-tension oil rings and a new PVC system, both of which are allowing too much oil to enter the combustion chambers to burn off early.…keep reading
Back in May GM admitted that they overstated the fuel economy on some 2016 SUVs
and offered a compensation program as a sorry 'bout that. Owners received somewhere between $450 to $1500, based on a few factors, for their troubles. But that wasn't enough for some.
A new lawsuit wants GM to pony up more cash for the decreased resale value of the 2016 Chevy Traverse, Buick Enclave, and GMC Acadia.
"The GM lawsuit says consumers who purchased those SUVs believed the vehicles were EPA-rated at 17 miles per gallon in city driving and 24 miles per gallon on the highway, resulting in a combined rating of 19 mpg. However, the plaintiffs say the Traverse, Enclave and Acadia are in fact rated at 15 mpg in city driving and 22 mpg on the highway, resulting in a combined rating of 17 mpg."
Listen, I get it – GM advertised one thing and produced another. That's no good. But if someone is looking to buy a large used SUV, then I'm not convinced that 2 MPGs are a deal breaker.keep reading
On September 13, 2015, Rayven Barfield parked her 2001 GMC Yukon in a driveway. She turned the ignition switch off, but left the keys in the ignition.
Later she heard someone screaming as the the SUV rolled away with a child in the driver's seat. What happens next is unimaginable.
"The plaintiff says she was running toward the Yukon and saw the driver's side door open as the SUV rolled down the driveway. Joseph Jr. fell or jumped out of the SUV, causing the front tire of the large SUV to run over the 3-year-old who was pronounced dead at a local hospital about an hour later."
The parents of the boy have filed a lawsuit saying defects in the gear shifting and ignition/park interlock systems. Let's hope something good comes out of this horrible tragedy.keep reading
The best way to find out what's wrong with a vehicle is from the people who drive them. Not only do owner complaints help us rank vehicles by reliability, but they're often used to spark class-action lawsuits and warranty extensions. Plus, they're a great way to vent.
