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    

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.
