GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

GM says its electric pickup truck is 'in development'

GM President Mark Reuss just reiterated the company's support for an electric pickup project. He also claimed that GM is going to be selling its future electric cars at "very average transaction prices" during the same conference with Wall Street analysts. Previously, Mary Barra informed the world of GM's electric pickup truck aspirations, but didn't tell us anything else. Reuss says the truck is already in development, though, according to a Wards Auto report. "We will have a complete electric lineup, including a pickup truck that's in development," Reuss said. This comment marks the second time GM has gone on the record about its intentions to bring an electric pickup to market. Additionally, Reuss said GM's third-generation global EV platform will be used to help develop the electric pickup. This platform was recently announced to underpin at least 20 new EVs from GM in the future — the platform itself is slated to be unveiled in 2021. Of course, this platform will be flexible and modular to allow various body styles to be used with it, a truck being one of those. Reuss still hasn't said what GM brand the pickup will be sold under, or what class of truck it will be. GM thinks this new platform is also going to be what helps it drive down the cost of building EVs. "We'll reach parity a lot sooner than people think," Reuss said comparing EVs to traditional gas-powered engines. "We're driving down the cost of batteries and the whole EV in general." As for electric pickups, Ford is also deep in development of its own electric F-150. However, neither of these truck projects have official timelines on them, so we can't say when they'll hit the market. For now, the cross-town rivals are both in development with their respective electric pickups. Even further across town is Rivian (in which Ford just invested half a billion dollars), a company that says its electric R1T pickup is right around the corner, with the official due date being end of 2020 for the time being.
