1. 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.

  2. It’s bad enough to have your truck recalled because the brake pedal might fall off.

    It gets worse when you find out there’s a good chance your truck wasn’t properly fixed … and the brake pedal still might fall off. When a 2015 Silverado that had previously been “repaired” as part of the recall was brought back in for service, it raised a big ole’ red flag.

    The automaker then learned the truck had been repaired under a February 2016 recall, something that caused the automaker to open a formal investigation. The GM investigator determined the truck had only been inspected and did not receive adhesive on the brake pivot pedal nut even though the recall procedures required it.

    GM is re-recalling 41,000 trucks to fix the problem. Maybe they’ll read the instructions this time.

  3. 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?

  4. GM says it needs to bleed the brake systems of 230,000 previously recalled cars.

    Some of the recalled vehicles have rear brake caliper pistons that have hydrogen gas trapped inside that could be released into the brake systems. ZF, the manufacturer of the brake pistons, didn't properly temper and chrome-coat the pistons, causing hydrogen gas to remain trapped in the bodies of the pistons.

    Excess gas –– we’ve all had it, no-one likes it, and the same holds true for your braking system. This problem may cause your brake pedal to feel “spongy” but it’s unclear if it affects stopping distances.

  5. During a crash sensing diagnostic modules (SDM) detect the impact and send a signal to the airbags to deploy.

    But according to CarComplaints.com, the SDM in the 2018 Acadia might not be powering down properly when the SUV is turned off. The module may stay deactivated when the SUV is restarted, showing an airbag warning light to the driver and a message that says “service restraint system." Additionally, a driver will hear warning chimes indicating the airbags are off.

    Basically, if it doesn’t shut down properly it won’t be able to turn on properly the next time the SUV is restarted. If that sounds familiar, GMC was part of a massive recall for similar module problems last year.…

  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. While you're probably still digesting that extra serving of holiday cookies, here's something else to chew on

    – GM says some 2017 Cadillac XT5 and GMC Acadia SUVs will have diminished braking ability because of hydraulic fluid leaks. Engineers found an oversized front caliper piston bore had allowed the piston seal to leak hydraulic brake fluid and it was determined the oversized bore can prevent the proper compression of the caliper piston seal.

    GM says a red "BRAKE" warning light will come on when this happens. So if you see that, stop driving as soon as possible – which in these SUVs could take quite a while. The bad caliper assemblies are on Acadias built between 04/19/2016 and 04/22/2016

  9. 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.…

  10. 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.
