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

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

First 2016 Chevy Volt commercial rocks us to sleep

The 2016 Chevrolet Volt, with its thorough restyling and increased all-electric range, is an exciting evolution of Chevy's groundbreaking plug-in hybrid, so it's only fitting that the commercial campaign to sell it to the masses also be engaging and vibrant. Well, the first ad has just been officially released and it rocks... us to sleep. Now, we get that General Motors didn't want to repeat past Volt-commercial mistakes. No one wants to see dogs licking feet or dumb (and weirdly horny) aliens again. Nor would it be smart to slam all-electric vehicles, since it now sells the Spark EV and has just revealed its 200-mile Bolt concept. So, what does that leave? How about a mostly computer-generated spot that relies on cliche images and an upbeat synthetic soundtrack to communicate that the Volt is now as boring as other four-door appliances? An intro, featuring a lightly-bearded gentleman peering at his tablet through designer glasses launches us into the action as the Volt makes its way across a city bridge, then a curvaceous country road. Chevrolet doesn't include voiceover to inform you that the new Volt has a 50-mile battery-only range. There's no mention of its gas mileage once its electric charge is depleted – items that just might be of importance to hybrid buyers. The ad also makes no attempt at establishing an emotional connection, either through drama or comedy. There are, however, lots of fast cuts of the new, normalized interior, including a two-second detail shot featuring the windshield wiper switch. We imagine that this is only the first in a series of spots that will tell the Volt story and motivate potential buyers to run down to their local dealer, hopefully the next spots will be more interesting and informative.
