Realted Problems

  1. 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…

  2. 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…

  1. 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. 👍🏼…

  2. GM allegedly cut corners by installing a fuel pump that isn’t compatible with US diesel in its larger trucks.

  3. 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.

  4. 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.

  5. 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.

    The lawsuit was filed back in 2015 after owners started questioning GM’s headlight redesign for the 2014 and 2015 model years.

    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.

  6. 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.…

  7. 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.…

  8. 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.…

  9. 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.

  10. 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.

  11. GM isn't arguing against claims that the 2014-2015 GMC Sierra has some terrible headlights

    , just that the lawsuits against them don't prove it. GM argues truck owners don't allege the lights malfunction in any way, so the case should be dismissed because other lawsuits have been dismissed because of similar claims.

    The plaintiffs are worried ineffective lights will lead to more nighttime crashes, but GM says they have no data to back it up. If the automaker actually needs data for that, then I'm not sure which is dimmer --- the headlights or GM itself.
