  2. 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…

Recent Relevant Lawsuits

The Suburban has been named as a class vehicle in the following lawsuits.

  • Tucker, et al., v. General Motors LLC.

    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.

    2010-2014 Sierra, 2010-2014 Yukon, 2010-2014 Yukon XL

  • Airko, Inc., et al., v. General Motors LLC.

    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.

  • Dismissed

    Szep, et al., v. General Motors LLC.

    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.

  • Martell, et al., v. General Motors LLC.

    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.

  • Manning, et al., v. General Motors Company, et al.

    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.

There's a lot of news out there, but not all of it matters. We try to boil down it to the most important bits about things that actually help you with your car problem. Interested in getting these stories in an email? Signup for free email alerts over at CarComplaints.com.

  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 may have used the wrong bolts to secure the seat belts in certain 2020 and 2021 Chevy models.

    Could the new bolts work? Maybe. But when it comes time to rely on the seat belts, it's better knowing the right parts were used to tether them to the frame.…

  3. A new class-action is accusing General Motors of knowingly selling vehicles that consume abnormally high quantities of oil.

    It's not the first time GM has been sued for oil issues in the Vortec engine. Specifically (and stick with me here) the Generation IV 5.3L V8 Vortec 5300 LC9 engine.

    As with previous lawsuits, the plaintiffs say low-tension piston rings, oil spray from the Active Fuel Management (AFM) system, and agressive vacuuming from the engine's positive crankcase ventilation (PCV) system are to blame.…

  4. There’s an important recall for parents who’ve installed child seats using a seat belt.

    For installation of the child seat using the seat belt, there are automatic retractor assemblies equipped with retractors that lock automatically.

    This should lock the seat belt when it is completely pulled out of the retractor. However, the defects can cause the retractor to not lock the seat belt when it is pulled out of the retractor.

  5. 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.

  6. Low voltage is temporarily disabling the power steering in more than 1 million GM trucks and SUVs, prompting a massive recall for the 2015 model year.

    A near carbon-copy recall was made for similar vehicles back in August 2017. The major difference? It was 2014 model year.

    Is anyone staffing the shoulda seen that coming department over at GM?
