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

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

2019 GMC Sierra CarbonPro Edition pricing starts above $65,000

GMC is hard at work building carbon fiber beds for its CarbonPro trucks, so it's fitting that the company has finally released pricing for the 2019 GMC Sierra CarbonPro Edition. It's not cheap by any measure. The most "affordable" for 2019 is the AT4 version starting at $66,635. It's also available in Denali trim, and that version starts at $70,020. Both represent an increase of $8,000 to $9,000 more over the base AT4 and Denali models. That may seem like a lot to go from a steel bed to a carbon fiber one, but you're getting more than the bed for that money. GMC also includes unique badging, a Bluetooth bed speaker, rear-camera mirror, surround vision cameras, automatic emergency braking, lane-keep assist, automatic headlights, power side steps, a sunroof, trailer tire pressure monitoring and a color heads-up display to both models. The AT4 specifically gets a Bose sound system, navigation, parking sensors and a cat-back exhaust, too. The Denali adds unique 22-inch wheels. Both only come with the 6.2-liter V8 and 10-speed automatic. To equip a regular GMC Sierra AT4 similarly to the CarbonPro Edition, the price comes out to $64,110. The Denali comparably equipped to the CarbonPro is $67,940. So the bed itself is about $2,000 to $3,000. The 2019 GMC Sierra CarbonPro Edition trucks should be reaching dealers very soon. They will soon be supplanted by the 2020 version, which will add the new 3.0-liter diesel inline-six as an engine option. The AT4 CarbonPro will get some extra black accents for 2020, too.
