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

2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.

J.D. Power customer survey of dealers counts Cadillac, Buick as big winners

Cadillac and Buick have taken the trophies in J.D. Power's latest Customer Service Index Study examining satisfaction with dealer service. Surveying more than 90,000 owners and lessees of 2009-2013 model-year cars, the study found that those with pre-paid maintenance packages were ten percent more likely to buy their next car from the same brand.
Dealer satisfaction scores have improved overall, Cadillac nabbed the luxury segment ahead of Audi and Lexus, taking the crown that Lexus held last year. Buick keeps the mass-market dealer satisfaction win in the family, finishing ahead of Volkswagen and last year's winner GMC. The study also found that service department use of tablets increased customer satisfaction, as did "best practices" like "providing helpful advice." Who knew?
You can find details on those and more findings in the press release below.
