GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

The electric Hummer gets a new logo

GM submitted three trademark applications to government offices here and in Canada, as discovered by GM Authority. Two applications went to the U.S. Patent and Trademark Office and the Canadian Intellectual Property Office on February 4 this year, seeking to reserve the new Hummer logo, at the top in the image above. Note, the two logos aren't to scale; they're about the same size all things being equal, but we shrunk the old mark. GM sent a second application to the USPTO on February 7 requesting the brand name "Hummer" for application to "motor land vehicles, namely, automobiles, trucks and sport utility vehicles; bicycles." True, we've seen the new Hummer script stretched across the front of the coming electric pickup in a teaser clip, but the paperwork continues the process of getting the entire continent ready for the alternate universe resurrection of one of America's most notorious brands.     In 2010, gas prices were in orbit, GM committed to closing the Hummer brand, vandals were setting fire to the scattered Hummers left on dealer lots, the Chevrolet Corvette ZR1 made 638 horsepower, the eco-minded revered the Toyota Prius and the Tesla Model S was still two years away. In that year, it would have been hard to say something more bonkers than, "Hummer's coming back in ten years as an electric pickup, its top trim making 1,000 horsepower and 11,500 pound-feet of torque." But here we are. The new logo's squareness connects it to the resolute bluntness of the old mark, yet the thinner font and chopped corners both modernize the old logo and lessen its truculence. The brand appears headed the same way, with lurid specs and square-jawed looks just like old times, but having in LeBron James a more modern take on the hardcore male vibe than it once got from (unpaid) association with guys like Arnold Schwarzenegger. To be fair, old Hummer commercials always featured women in the driver's seat, or men and young boys dreaming of big adventures, or Regis Philbin chatting up models, but the marketing department couldn't — or didn't want to — outrun the lineup's reputation on the street. We'll see how the electric version and its “incredible on- and off-road capability" fare. According to the teaser site, the new Hummer's debut is still on track for May 20. If the brand manages to recreate the old H3T pickup but with an electric powertrain, it's got one buyer right here lined up already. Related Video:

2019 GMC Sierra 1500 prototype shows off differences from Silverado

Now that the new Silverado has made its debut, we're awaiting the reveal of its mildly restyled twin, the GMC Sierra 1500. While it likely won't be that different as far as capability and major equipment are concerned, we are looking forward to seeing what design changes it will have. Based on these recent spy shots, the changes will be mild, but still enough to make it visually distinctive. One of the more obvious differences will be in the front fascia treatment. Unlike the Silverado's grille that's level with the top of the headlights, the GMC's will rise above the lights, which will also yield a slight drop on each side of the hood to meet the lights. The grille is quite tall, extending far below the headlights, too. We can make out, behind some mesh, two dips on the outer edges of the grille that give the Sierra a more menacing frown. Large foglights are also found right near where the scoops for the wheel air curtains, and the headlights are unified on the edges, rather than split on the Silverado. Along the sides, the sheet metal looks relatively unchanged. At some angles, we can make out the distinctive shoulder line from the Silverado that runs up to about the rear mirrors where it stops to make room for another crease that rises up from somewhere in the middle of the front doors to lead to the front. The wheel arches are decidedly different from the Silverado's though. While the Silverado has fairly rounded arches, the Sierra's have a rear-slanted bevel to the fronts of the arches and a rounded 90-degree corner at the rears. There isn't much we can tell about the rear except for the taillights. They're quite large, and unlike the Silverado's, there aren't any areas where the sheet metal intrudes. It also appears that the tops of the taillights extend farther forward into the bed sides than the Chevy's. Because the Sierra has almost always been a mechanical twin of the Silverado, we expect it to offer the same 5.3-liter and 6.2-liter V8s, as well as the new 3.0-liter diesel inline-6. Also, being a GMC, it will likely have a flashy, chrome-laden Denali trim level. We also will see the fully revealed model soon, as Automotive News reports the debut will be on March 1.
