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.

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.

Trucks with the best gas mileage for 2024

There's no denying that pickup trucks are an integral part of our culture. They've been instrumental in building our infrastructure and giving the public access to remote locations and myriad recreation activities. Trucks aren't known for being particularly fuel efficient though, with boxy silhouettes and considerable weight negatively affecting their gas mileage ratings. The times are changing and not only are trucks getting more economical, but there are also several new smaller alternatives. An efficient tuck doesn't have to by tiny, though. Some of the trucks with the best gas mileage look classically bulky. What is the most fuel-efficient truck? So what's the most fuel-efficient pickup truck on sale in the U.S? It depends on which class of trucks you're looking at. For this list, we're focusing only on internal-combustion trucks. The small crop of all-electric trucks are certainly worth considering, but it's not so easy comparing EVs to ICE trucks here. In most cases, these trucks are the two-wheel-drive versions since they return the best mileage, but there are a few four- or all-wheel-drive models that we call out.  Not surprisingly, the revival of the compact pickup has altered the truck landscape. In many cases, these petite trucks may be just the right size for many shoppers. That's great because most owners would rather not lug around a ton of weight that they don't necessarily need. The simplest answer to the question posed above is the Ford Maverick Hybrid. It tops this list of fuel-efficient truckswith an impressive 37-mpg EPA estimate for combined city and highway miles. With only 191 horsepower and a continuously variable transmission, it's not as capable off-road or for towing as other trucks, but if you just need something to haul stuff around, you really can't do any better. Its 4.5-foot bed has a slight advantage over its only rival, the Hyundai Santa Cruz, which has a 4-foot bed and an estimate of 23 mpg. So now we know what truck uses the least amount of gas. 2024 Ford Maverick 2.5-liter hybrid powertrain 37 mpg combined (EPA estimate) What is the most fuel-efficient midsize truck? While not as popular as their full-size siblings, midsize strike a good balance of utility and drivability. They’re easier to navigate in a crowded parking lot, and fit down more trails earning a set of Arizona pinstripes.
