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.

2015 Chevy Tahoe gets Police Patrol Vehicle treatment

That was fast. Mere days after showing a Police Concept based on the 2015 Tahoe at the SEMA Show, Chevrolet has announced that it will build a PPV model based on the SUV to do battle with the Ford Police Interceptor Utility (Explorer) and Dodge Durango Special Service.
You'll recall that the Tahoe has been police staple for several years, predating both the Explorer and Durango police variants, so the fact that the new model would spawn a police variant is hardly surprising. Like the civilian model, the 2015 PPV benefits from a more efficient 5.3-liter, direct-injection V8 that pumps out 355 horsepower and 383 pound-feet of torque. It also features more high-strength steel, offering better crash protection, on top of optional safety items like lane departure warning, forward collision alert and a Safety Alert Seat.
The press release is rather light on police-specific items, aside from the auxiliary battery, which keeps the myriad of electronics in a modern police car running even when the engine isn't. Lightbars, 17-inch steel wheels on Goodyear Eagle RS-A tires and a push bar round out the mods for the Tahoe PPV. The cabin features a revised center console and room for laptop and other equipment mounts.

Chevy Bolt to start at $37,500 before rebates

During the recent debut at the Consumer Electronics Show, Chevrolet only described the 2017 Bolt's cost as "affordable" without any further explanation. Now the company's promo site for the EV spilled the beans of the $37,500 price after destination. That means some buyers could get the five-door hatch for $30,000 after the $7,500 federal tax credit – at least as long as that lasts for the Bowtie brand. State incentives might also reduce the bill even more when the Bolt arrives in late 2016. Chevy wants the Bolt to be a mainstream and affordable vehicle that can attract a wide swath of buyers. The company estimates the five-door's range at over 200 miles, which should be plenty for most customers. The promo site also touts that the batteries can recharge in nine hours from the automaker's 240-volt home charger. Inside, buyers find a high-tech cabin with a customizable 10.2-inch infotainment screen and an 8-inch instrument display. To limit range anxiety, the vehicle's computers can take into account the way an owner drives, the weather, terrain, and more to calculate just how much distance remains from the batteries. The system also pushes people to be greener drivers through a game-like interface that offers rewards and rankings. If $37,500 or less for this five-door EV intrigues you, read our Quick Spin of a preproduction example from CES for a better idea of what the Bolt is really like. The powertrain's regenerative braking impressed us even over the short driving course, and the infotainment system seemed incredibly useful. Related Video:
