  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. 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.

  4. A lawsuit filed in Oklahoma says GM’s A/C will only blow hot air due to multiple defects in the HVAC system.

    And that the automaker wasn’t upfront about the problem.

    The lawsuit says there are at least two defective parts of the air conditioning system, the first being the line leading from the compressor to the condenser. This line consists primarily of an aluminum tube connected to a rubber hose, but the plaintiffs claim the tube can disconnect from the rubber hose and allow the refrigerant to leak.
    Additionally, the aluminum tube is allegedly defective because it can rupture and allow the leak to occur.

  5. 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.

    GM 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.
