GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, 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 Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will 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. Recalls Chevrolet GM GMC

GMC Hummer EVs 'sold out for two years or more'

At the end of March this year, GMC said it had 65,000 reservations for the Hummer EV pickup and SUV. At the time, brand chief Duncan Aldred said, "Production’s actually slightly ahead of plan and weÂ’re putting things in place now to actually expedite that as well, so we can deliver these reservations quicker than we originally thought. WeÂ’re seeing momentum building," adding that "it still means a reservation now probably means delivering in '24." By the time of the 2024 GMC Sierra EV Denali Edition 1 reveal just a bit ago, that reservation number had climbed to 90,000. GMC shut down the Hummer reservations line a month ago. GM Authority reports that when GMC chief Duncan Aldred spoke at a media briefing ahead of the Sierra EV reveal, he said the Hummer is "sold out for two years or more."   Notice, the word "probably" has been replaced by the phrase "or more" in the production vocabulary. That development likely takes into account what's happened since March at GM's Factory Zero, where the automaker currently builds the Hummer. That site, along with the new Orion Township Assembly Plant, will soon build the Chevrolet Silverado EV, GMC Sierra EV and Cruise Origin autonomous vehicle. In a memo from the beginning of the year, GM said a $6.6 billion investment in EV production capability will ultimately allow 600,000 electric pickups to come off lines every year. That's at least a couple of years away, though. At the beginning of October, GM said it wanted to bump production of the EVs on sale now, which includes the Chevrolet Bolt, to 70,000 vehicles in 2023. Back to the Hummer, GMC increased September Hummer production to 700 units for the month. That was a huge bump over the monthly average in the nine months up to September, the production totaling 2,750 units for the first three quarters, yet well behind what the brand would like. And Factory Zero will shut down for a few weeks in November for upgrades to produce the additional vehicles. All of this assumes the supplies of chips and raw minerals for batteries, industrial supplies and industrial transport don't suffer another hiccup. If there's any good news buried in all this, it's that 95% of Hummer reservation holders were converting to paid orders, an absurdly positive number. Based on what we've seen so far, GM's got some good looking EVs on the way. Let's cross our fingers that the company can build them quicker. Related video: This content is hosted by a third party.

2020 GMC Acadia refresh brings a new engine, AT4 trim level

It's mid-cycle refresh time for the GMC Acadia, and the updated 2020 model kicks off its changes with a new face. It has a square-jawed grille seemingly pulled straight off the Sierra full-size pickup, and the size is amplified by the slender new LED headlights on either side. At the rear, the LED taillights are taller and more chiseled. A new AT4 trim level adds more visual distinction with black trim and wheels, plus all-terrain tires to make it a little more capable off road. The AT4 also boasts standard all-wheel drive. Under the revised skin, the Acadia hides one of two carryover engines, or a new turbocharged 2.0-liter inline-4. This new engine makes 230 horsepower and 258 pound-feet of torque with the help of a twin-scroll turbocharger. To make it more frugal, it's able to deactivate two of its four cylinders. The turbo engine is standard issue on the SLT and Denali trim levels. The carryover engines include a naturally aspirated 2.5-liter 4-cylinder making 193 horsepower and 188 pound-feet of torque, and a naturally aspirated 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque. The V6 is standard equipment on the AT4 trim. No matter the engine, all 2020 Acadias get a 9-speed automatic transmission. The new transmission also ditches the current Acadia's mechanical shift lever in favor of an electronic shifter with the Terrain's mix of buttons and triggers. It does free up space between the seats, but the button arrangement is still as strange as it was when we first saw it in the smaller crossover. There are a handful of other little upgrades to mention. The suspension has been revised for greater comfort; the infotainment has been revised with a bigger screen, USB-C inputs and customizable profiles; and wireless phone charging is now an option. The updated Acadia goes on sale this fall, and pricing will probably be announced close to launch.
