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.

2016 Chevy Volt powertrain video teasers

If there's one thing we've learned about plug-in vehicle fans, you have a thing for seeing your cars get made. The series of videos showing BMW i3 production was strangely popular, as were the shots from inside the VW e-Golf plant. Well, with General Motors pulling the veil off of the 2016 Chevy Volt this week, it's time to take a peek at the production process for that vehicle as well. You're welcome. Up first we've got a clip from CNN Money showing a little bit about how the new Volt's new battery pack and other powertrain components are made. Those of you who are trying to read the lithium tea leaves and see if the new shape reveals that the 2016 Volt will have five seats might want to check it out. Then we've got two clips from GM itself, one showing an animation about the updated Voltec powertrain and another with some B Roll of the old Volt. Since GM doesn't want us to see the new car quite yet, we'll have to enjoy this for now. Watch below. This content is hosted by a third party. To view it, please update your privacy preferences.

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.
