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 Cadillac CTS-V prepares to kick ass, take names

Some stories write themselves. This post on the North American International Auto Show debut of the 2016 Cadillac CTS-V is one of them. This 200-mile-per-hour sedan pilfers the 6.2-liter supercharged V8 from the Chevy Corvette Z06, and puts it to the same tire-devastating effect, offering up 640 horsepower and 630 pound-feet of torque. An eight-speed automatic – please join us in a moment of silence for the dearly departed manual CTS-V – then dispatches the force-induced thrust to a very large, sticky set of Michelin Pilot Super Sport tires. To ensure the CTS-V can tear your face off with lateral Gs as well as accelerative Gs, Cadillac stiffened the car's structure by 25 percent, fitted magnetic ride control and fitted the aforementioned tires. Beyond the mechanicals, a substantial rear spoiler, front splitter and diffuser improve grip through aerodynamics. Keeping drivers pinned during all this tire shredding and face tearing is the task of meaty, two-piece Recaro sport seats, which are found in a luxuriously appointed cabin, complete with 4G LTE connectivity, a Bose stereo and Siri Eyes Free. There's even a Performance Data Recorder, which will be on hand to record your miscues if (or perhaps when) the car's extreme abilities outpace your own talents. Take a look at our array of live images from the CTS-V's official debut at the 2015 Detroit Auto Show.

Crowd lifts Cadillac to free pedestrian after two vehicles barrel toward him

An elderly Missourian is lucky to be alive today after a car that had pinned him to the ground was lifted off him by witnesses. According to WDAF, Orlando Gentry and Troy Robertson were working at a Kansas City, Mo., clothing store when a stolen minivan careened through a red light at 35th and Prospect and was immediately T-boned by a woman driving a gold Cadillac. The impact drove both vehicles up onto the sidewalk at the corner, side by side, directly at pedestrian Carlos Green. "We was out here with our kids, and we was at work, and the next thing we heard was a boom!" Gentry told WDAF. "Man, those cars came out of nowhere, and Carlos was just helpless," Robertson said. Gentry tried to escape but was caught between the vehicles and pinned beneath the Caddy. Then a light pole punctuated the crash by falling on top of the Caddy - and almost on top of Carlos Green. "Yeah, he tried to jump out of the way, but he just got pinned underneath the Cadillac. He definitely hurt his right leg. When I saw all that, I screamed, 'Somebody help me help get this car off Carlos,'" Robertson said. He, Gentry and passersby lifted the heavy Caddy off Green so he could crawl free. Thankfully, Green wasn't seriously injured. He was discharged from an area hospital bruised, with one leg in a cast, but ultimately healthy. The woman driving the Cadillac was unhurt, but the two men driving the minivan ran off during the confusion. Kansas City police are looking for the escaped car thieves. This is the second time in as many weeks that people banded together to lift a car off someone. On May 9 in Philadelphia, a group of good Samaritans lifted an SUV off a little girl who had been run down and pinned beneath an SUV tire. Related Video:
