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.

2013 Cadillac ATS Premium 2.0T 6MT

The new Cadillac ATS is an impressive sport sedan, often considered one of the most serious threats to the BMW 3 Series. Unlike GM's previous attempts, this four door brings aggressive styling, commendable chassis dynamics and class-leading handling to the highly competitive battle. And, like its daunting German foe, Cadillac offer several powertrain choices.
I recently spent time with the ATS 2.0T Premium on my home California turf. Fitted with a turbocharged 2.0-liter four-cylinder engine mated to a six-speed manual gearbox with a limited-slip rear differential, my tester was lightly optioned, with only a paint upgrade and a cold weather package. That brought the as-tested price to $46,305, configured the way I imagine most enthusiasts would prefer. This meant I fully expected to enjoy a week with a tossable sport sedan that boasted "fun-to-drive" as its middle name, but all was not well...
