1. A federal investigation wants to know if rusty connectors are preventing 2020-2021 GM airbags from deploying.

    The National Highway Traffic Safety Administration (NHTSA) has received six reports of severe crashes where the airbags didn't deploy in GM vehicles, despite those vehicles receiving "significant frontal damage." All six crashes resulted in injuries.…

  2. 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. 👍🏼…

  3. 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.

  4. 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.…

  5. 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.…

  6. 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.…

  7. 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.

  8. The modules that help control the airbags and seat belt pretensioners in a crash aren't working in 4 million GM vehicles, prompting a massive recall

    that includes the GMC Sierra 1500/2500/3500, and Yukon. GM received an internal report in May relating to the crash of a 2014 Chevrolet Silverado where the driver’s frontal airbag and seatbelt pretensioners were alleged not to have deployed.

    GM opened an investigation into the issue in June and contacted Delphi, the supplier of the sensing and diagnostic module. The automaker gathered additional electronic data recorder records from other incidents where the same crash symptoms occurred.

    The modules will need to be reprogrammed, GM just doesn't know when yet.

  9. GM is recalling nearly 4,800 new trucks and SUVs

    , and telling their owners to stop driving until their front upper control arms can be repaired. The automaker blames the problem on a bad weld near the control arm bushing, a problem the automaker discovered on a GMC Yukon XL Denali. The faulty weld can cause the control arm to change shape and eventually separate.

    If you own a 2016 GMC Sierra, Yukon, or Yukon XL you should call your local service center right away. While you're on the phone, ask them about getting a tow for repairs and how to get a loaner vehicle in the meantime.…
