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.

Kurt Busch suspended indefinitely after losing appeal

NASCAR has officially suspended Kurt Busch indefinitely after he was found in violation of two specific clauses in the stock racing rulebook, specifically "Actions detrimental to stock car racing" and a "Behavioral Penalty." Earlier in the week, the State of Delaware issued an Order of Protection from Abuse against him after a case detailing alleged domestic violence committed by Busch against his girlfriend, Patricia Driscoll, reached its conclusion. Busch and his legal team have exhausted all of their appeals options, meaning the indefinite suspension is official and final. Busch will not take part in the Daytona 500, which kicks off the 2015 NASCAR season today. Regan Smith will drive the No. 41 Stewart-Haas Chevrolet today at Daytona. It's not yet clear if Busch will face criminal charges over the domestic abuse incident. A Commissioner for Kent County in Delaware found that a "preponderance of evidence" led him to conclude that Busch did indeed commit "an act of domestic violence" against Driscoll, but that is a separate matter from the police investigation into the incident that is now in the hands of the office of the attorney general. NASCAR INDEFINITELY SUSPENDS DRIVER KURT BUSCH Daytona Beach, Fla. (Feb. 20, 2015) -- NASCAR has indefinitely suspended driver Kurt Busch for actions detrimental to stock car racing following the release today of a supplemental disposition setting forth the findings and conclusions that formed the basis for the Family Court of the State of Delaware's decision on Monday to issue an Order of Protection from Abuse against him. Busch, driver of the No. 41 car, was found to be in violation of: • Section 12.1.a: Actions detrimental to stock car racing • Section 12.8: Behavioral Penalty "Given the serious nature of the findings and conclusions made by the Commissioner of the Family Court of the State of Delaware, NASCAR has indefinitely suspended driver Kurt Busch, effective immediately. He will not be allowed to race nor participate in any NASCAR activities until further notice. "Kurt Busch and his Stewart-Haas Racing team are fully aware of our position and why this decision was made. We will continue to respect the process and timetable of the authorities involved."

GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.
