GM recalling 8.4M cars, 8.2M related to ignition problems

General Motors today announced a truly massive recall covering some 8.4 million vehicles in North America. Most significantly, 8.2 million examples of the affected vehicles are being called back due to "unintended ignition key rotation," though GM spokesperson Alan Adler tells Autoblog that this issue is not like the infamous Chevy Cobalt ignition switch fiasco.
For the sake of perspective, translated to US population, this total recall figure would equal a car for each resident of New Hampshire, Rhode Island, Montana, Delaware, South Dakota, Alaska, North Dakota, the District of Columbia, Vermont and Wyoming. Combined. Here's how it all breaks down:
7,610,862 vehicles in North America being recalled for unintended ignition key rotation. 6,805,679 are in the United States.

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 teases Hummer EV's removable roof panels

Today was supposed to be the day that GM took the wraps off its GMC Hummer EV. We were told as much during the Super Bowl commercial, but GM revised it to an undecided future date, citing the coronavirus as the reason. Instead of the big reveal, we have a teaser.  The Hummer EV is going to feature removable roof panels, and now we get a better look at them. There are four roof panels and a front T-bar that come out of the truck. You can see what that looks like in the video at the top of this post. Comparisons to Jeep are obvious as the open-air experience is likely similar to the Gladiator and Wrangler with their hardtop roof panels removed. That zero-limits slogan makes a bit of sense from this respect. With the sheer number of roof panels, we suspect a single person will be able to remove them alone. In addition to the video of the roof, we get a small peek at the massive digital screens the Hummer will be sporting. Check them out at the bottom of the photo below. They appear to be two large slabs, separate from each other. Other details are scarce on the ground. We’re not sure when the Hummer will make its grand entrance at this point, but are still excited to see the 1,000-horsepower truck hit the road. GMC is still advertising the 0-60 mph time of just 3 seconds, too. The latest tidbit of news suggests that further teasers might be coming, so we could be in for a rather drawn out reveal process. Our senior green editor John Snyder got to see the GMC Hummer in person earlier this year at GMÂ’s EV Day and described it like this: “ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel.” Related video:
