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 to build outgoing Silverado and Sierra until late 2019

As it has done with previous generations, General Motors is keeping the outgoing versions of its 1500 pickups in production despite the arrival of the all-new 2019 Chevrolet Silverado and 2019 GMC Sierra. The production of the previous, K2 generation models will begin to be wound down gradually, according to Automotive News, starting with crew cabs "early next year," and double and regular cab models following during "the early second half of next year." The old model trucks will continue to be built into "late 2019" based on market demand, GM's spokesperson Kim Carpenter said. The Chevrolet will go by the name Silverado LD, with the GMC Sierra designation still to be announced. Some of the outgoing models are built by sharing the assembly work between two GM plants. Partially finished Silverado and Sierra double cab bodies are shipped from Fort Wayne, Ind., to Oshawa, Ont., where the trucks are completed, including receiving paint. This eases the workload in Fort Wayne, where production of the new T1 generation trucks started in July 2018. In January, the Silao plant in Mexico will take on the duties of building new generation regular cab and crew cab trucks. Carpenter also said that the "Oshawa shuttle," as the shared production is called, has been very successful. As a result, 60,000 more trucks will be built than what the original production forecast initially called for. GM's latest quarterly profits, disclosed last week to be $1 billion, have been far higher than expected and will result in full-year profits far higher than what had been predicted in light of steel tariffs. GM isn't the only truck maker taking a similar multi-generation approach for 2019. Both the outgoing and redesigned Ram 1500 are in production, with the previous generation being dubbed Ram 1500 Classic. Related Video:

2014 Chevrolet Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.
