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.

2016 Chevrolet Malibu Hybrid: 48 mpg for $28,645

With the 2016 Chevrolet Malibu Hybrid, General Motors wants to show it's as serious about mainstream hybrids as it is about mainstream midsize sedans. Keeping with the theme, Chevy announced the Malibu Hybrid will have a serious price tag of $28,645. Chevy said Thursday the 2016 Malibu Hybrid will go on sale in the spring, with that price also including an $875 destination charge. That's about $3,000 more than where the Ford Fusion Hybrid kicks off, and about $2,000 more than a Toyota Camry Hybrid LE. The big news being pushed with the Malibu Hybrid, however, is the fuel economy. GM says it's capable of 48 miles per gallon city and 45 highway, for a combined rating of 47 mpg. That's better than any other 2016 midsize hybrid sedan. Power comes from a 1.8-liter gasoline engine and an electric motor with a 1.5-kWh lithium-ion battery, producing 182 combined horsepower. That's competitive with both the Camry and Fusion. Chevy also likes to say it's roughly the same system as the one installed in the 2016 Volt – although with a smaller battery, larger gas engine, and without the plug – so the Malibu Hybrid has that halo effect going for it. With both this Malibu and 2016 Toyota Prius, there's a lot of activity around gas-electric hybrids amid lowering fuel prices and a raft of plug-ins and full-electrics. The gas-only 2016 Malibu was found to be, "at least good again," so the 2016 Malibu Hybrid should be able to attract those who want a competent midsize sedan with excellent fuel economy that awaits EPA verification. We'll go with that thought until we get to drive it.

"The Malibu leverages knowledge and technology directly from the second-generation Chevrolet Volt," said Steve Majoros, marketing director of Chevrolet Cars and Crossovers. "By leveraging technology, we are broadening our level of expertise and lessons learned to bring consumers a world-class hybrid." With an all-new, hybrid powertrain that uses a slightly modified drive unit and electric motors used in the 2016 Chevrolet Volt, the Malibu Hybrid offers a GM-estimated 48 mpg city, 45 mpg highway – and 47 mpg combined, unsurpassed in the midsize car segment. Official EPA estimates are pending.

Next-gen Chevy Volt gets Corvette looks, adjustable regen levels

The hood may say "full speed ahead." The regenerative braking system says "slow down a bit." One person's automotive improvements is another's identity crisis, all in a day's work analyzing the new Chevrolet Volt. The next-generation version of General Motors' first extended-range plug in will include design touches taken from to the new Chevrolet Corvette, GM's iconic sports car. Hexagonal taillights and a "taut" hood will be part of the new package, Automotive News says, citing General Motors design chief Ed Wilbur. But does that mean the Volt is shedding any of its green-car cred? Not at all, if one considers that the Volt will also let the driver adjust the degree of regenerative braking using steering-wheel paddles to dial up and recapture as much energy as possible and engage in "one-pedal" driving or turn it down for easier coasting. Check out the 55-second video below featuring GM executives Mark Reuss and Andrew Farah trying out the Volt's new regenerative-braking system that was first used on the Cadillac ELR. GM will have more details for us when it unveils the 2016 Chevy Volt at the North American Auto Show in Detroit next month. The new version is said to have a larger battery, a longer all-electric driving range and more power, but Chevy's been fairly mum on those sorts of performance details so far.
