  1. GM did the right thing by recalling ineffective seat belts a few years back. It just would have been so much better if they used the right replacement parts.

    Now to be fair, only 2,800 of the over 1 million recalled vehicles ended up with the wrong pretensioner cable assemblies but considering the last recalls were in 2016 and 2018 this probably won't sit well with the owners driving around with the wrong seat belts for the last few years.…

  2. 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.…

  3. 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. 👍🏼…

  5. You’ve barely had a chance to get your 2019 truck dirty before buzzkill GM comes knocking for a recall of damaged airbag control modules.

    The busted module means the passenger side airbag might not deploy in a crash … or maybe it will? No-one really knows and that’s kind of the point.

    The recall covers the 2019 Chevy Silverado 1500 / GMC Sierra 1500 and is expected to begin on December 26th. I’m glad they didn’t plan it for the 24th, the traffic can be awful with all those grandma and reindeer collisions.

  6. 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.

  7. 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.
