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

2019 GMC Yukon Graphite Edition offers Denali engine and features without the chrome

A sporty-looking option package called RST was recently introduced for the Chevy Tahoe and Suburban that also offered the option of a 6.2-liter V8 and magnetic suspension. Now GMC is getting in on the action with the GMC Yukon and Yukon XL Graphite Edition. The trim package adds a number of visual enhancements, and, if you're so inclined, has a performance version with the same 6.2-liter V8 and magnetic suspension as the Tahoe RST and Yukon Denali. As for appearances, the Graphite Edition adds black trim almost everywhere, including the roof rails, grille, fog light surrounds, and window surrounds. It also adds 22-inch wheels, regardless of whether it's just the appearance version or the performance version. The appearance package has machined-finish wheels, and the performance package has black painted wheels. As previously mentioned, the performance version of the Graphite Edition adds magnetic suspension and the 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque found on the Denali and the Tahoe and Suburban RSTs. It's coupled to a 10-speed automatic transmission, and gets a rear axle ratio of 3.23:1. It also gets a few other Denali features such as a color heads-up display, Bose noise cancellation, a 170-amp alternator, and a trailer brake controller. The Graphite Edition can be had with both two-wheel drive or four-wheel drive. The Graphite Edition can only be had on Yukon and Yukon XL SLT models. Pricing hasn't been announced yet, but it's likely it will be a bit more affordable than buying a Denali model.

2021 GMC Yukon Denali adds another extra-luxe accessories bundle

For the 2018 GMC Yukon Denali, GMC added a Denali Ultimate Package that combined every option already available with some 22-inch Midnight Silver rims. In 2020, GMC expanded build options for the Terrain with a Denali Premium Package, lumping together a couple of a la carte packages as an exclusive mix of features. The 2020 Yukon Denali configurator includes a lightweight Denali Premium Package, too, but for 2021 GM Authority reports the top-tier choices will expand to include an entry-level Denali Deluxe Package along with the Denali Premium and Ultimate options. The Deluxe Package checks the boxes for the Advanced Technology Package, Advanced Security Package, and the Rear Seat Media System. The long list of tech roped in with that trio includes adaptive cruise control, enhanced automatic emergency braking, rear camera mirror and washer, interior movement sensors, glass break sensors, dual 12.6-inch rear seat-mounted screens, two HDMI ports, and wireless projection capability. The exterior showpiece is a quartet of 22-inch bright machined aluminum wheels with premium paint, affixed with wheel locks. Go with those rims and the Denali Deluxe Package costs $5,750, opting for a different set of wheels can drop the price to $3,775. On top of that, choosing the right combination of options to go with the Deluxe Package can lower the price another $500. The Denali Premium Package includes almost everything above, only omitting the Rear Seat Media Package. In place of the screens for back-seaters, the bundle installs a powered panoramic sunroof and power-retractable assist steps with perimeter lighting. Purchased with the 22-inch wheels, this assortment runs $7,000, or $5,025 with a different set of wheels. Here again, the right combination of additional packages can save $500. The Denali Ultimate Package combines everything in the bundles above, plus the Max Trailering Package that gets GMC's ProGrade Trailering System and high-capacity engine cooling. The price is $10,460 on a rear-wheel drive Yukon Denali, $11,255 on the four-wheel drive models. Choosing a different wheel only saves $1,000 in this case, and there's no extra discount available. The 2021 Yukon is expected to enter production next month at GM's Arlington Plant in Texas, Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
