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’s Charlie Wilson was right: Stronger regulations can help U.S. automakers

Charlie Wilson had been the president and CEO of General Motors before being nominated to become secretary of defense by Dwight Eisenhower. During his Senate confirmation hearings, he controversially said, "For years I thought what was good for our country was good for General Motors, and vice versa." And he was right. While car companies aren't necessarily the most progressive when it comes to things that might have the slightest possibility of political blowback, General Motors should be credited for doing something absolutely forthright in this regard with its announcement that it wants the federal U.S. government not to squash the California Air Resources Board's emissions requirements but to actually create a 50-state "National Zero Emissions Vehicle" program that, in the words of Mark Reuss, executive vice president and president, Global Product Group and Cadillac, "will drive the scale and infrastructure investments needed to allow the U.S. to lead the way to a zero emission future." Filing comments to the Safer Affordable Fuel-Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks is one thing. But a graphic the company developed for this announcement — shown above — is something else entirely, something that is absolutely credible, creative and clever. There is a photo of a Chevrolet Bolt EV driving along a highway, which seems to be in Marin County (based on the blurred San Francisco skyline in the background). Text on the photo states: "It's Time for American Leadership in Zero Emissions Vehicles." It seems to say, in effect, "If we want to make America great again, then we're going to do it by leading in technology, not by retreating behind weakened regulations." General Motors understands that the auto market is globally competitive, and if U.S.-based companies are going to be in the game, then they'd better be able to out-innovate the companies based elsewhere, where emissions and economy standards are not being weakened.

Ford GT dominates Le Mans qualifying, gets slapped with performance adjustment

Fifty years after Bruce McLaren and Chris Amon drove the Ford GT40 to victory at the 24 Hours of Le Mans, Ford is poised for a historic return to the Circuit de la Sarthe. The new Ford GT took the top two qualifying positions in the LMGTE Pro class, and four of the top five. Ferrari's 488 filled in the rest of the spots in the top seven, the first two from AF Corse. In other words, we're primed for a reboot of the classic Ford-Ferrari feud at this year's race. Or not, as the ACO, which organizes the 24 Hours of Le Mans, announced sweeping pre-race Balance of Performance (BOP) adjustments this morning that make this year's GT class anybody's race. In LMP1, last year's overall winner Porsche locked up the top two spots with the 919 Hybrid and will lead the entire field at race start. Toyota's two-car factory effort followed with qualifying times 1.004 and 2.170 seconds behind the pole lap. Audi rounds out the manufacturer-backed LMP1 class in fifth and sixth. Full qualifying results can be found here. The storyline for the GT cars is perfect - some say too perfect. Ford's class-leading times came after BOP adjustment to the Corvette Racing C7.R before qualifying. BOP is intended to level the playing field in the class by adjusting power, ballast, and fuel capacity. (Check out this explainer video for more, or even just if you love French accents.) But the process is riddled with unknowns and ripe for accusations of sandbagging. That is, if the Ford cars were intentionally slow in practice they could hope for BOP adjustment to improve their race chances. On the Corvette side, last year's GTE Pro winner went from the top of the field to the bottom, barely improving from practice to qualifying. If you think Le Mans is as rigged at the NBA Playoffs, well, it's not that simple. Because if Ford and Ferrari held back until qualifying - the eighth-place Porsche 911 RSR is three-and-a-half seconds off the class pole time - it was a pretty dumb strategy. This morning, the ACO tried to put things back in order by limiting the boost in the Ford GT's twin-turbo V6 and adding 11 pounds of ballast. Ferrari was also given extra weight but allowed more fuel capacity. The Corvette and Aston Martin teams were both given breaks on their air restrictors, which will allow their engines to make more power. Both Ford and Porsche also received extra fuel capacity.
