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.
Chevrolet has recalled 460 Bolt EVs to fix leaky front-left brake calipers. The automaker believes the calipers weren't cast properly, allowing them to leak during hard stops. Losing brake fluid is never great, but the real concern is that the caliper could eventually fracture and no-one enjoys a sudden loss of braking power.
General Motors has been sued for last month's Bolt EV recall which temporarily limits the battery's capacity to 90%, bringing the car's range down from 238 miles to roughly 214. The plaintiff says the software update is giving him "range anxiety" and that's only heightened by the impending cold weather months which can also limit range. Last I checked, winter was going to happen regardless of the recall and it could just be me but I'd be more anxious about the possibility of my car catching on fire than losing 14 miles of range.
General Motors is recalling roughly 68,700 Bolt EVs to temporarily limit their battery capacities hoping it'll prevent further battery fires. The automaker has confirmed five fires are the result of a defect inside the EV's high-voltage battery systems. The batteries contain cells from LG Chem and as they approach a 100% charged state there's an issue that can cause a short-circuit and spark a flame.
The National Highway Traffic Safety Administation (NHTSA) has opened a federal investigation into the 2017-2020 Bolt EV following three reports of fires while the cars were parked and unoccupied. All three reports seemed to have happened as the car was charging or parked with nearly a 100% charge.
Excess gas –– we’ve all had it, no-one likes it, and the same holds true for your braking system. GM says it needs to bleed the brake systems of 230,000 cars because the 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.
