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.

Cadillac CT6 hits dealers in March for $54,490

When the Cadillac CT6 hits dealerships in March of 2016, it will carry a starting price of $54,490 (including a $995 destination charge). That strikes us as a reasonable asking price. For some context, the CTS, which sits a rung down the size and pricing ladder at Cadillac, starts at $46,555. A BMW 5 Series sedan begins its pricing journey at a bit over $50,000 while the larger 7 Series commands a bare minimum of $82,000. So, while the Cadillac's range-topping CT6 isn't exactly a 5 Series or 7 Series competitor, its pricing strategy seems to reflect an interesting position in the luxury-car playing field. For that $55,000-ish asking price, the CT6 comes equipped with a 2.0-liter turbocharged four-cylinder engine that pushes 272 horsepower to the rear wheels. When equipped with a 335-horsepower, 3.6-liter V6 engine and all-wheel drive, the CT6 nudges up just slightly to $56,490. Again, that's a reasonable $2,000 surcharge for more power and four driven wheels. Continuing up the CT6 structure brings us to the 400-horsepower, twin-turbo, 3.0-liter V6 for $65,390 that also comes with all-wheel drive. All models come with an eight-speed automatic transmission. At the very top of the pricing scale sits the CT6 Platinum, which carries a MSRP of $84,460. As noted earlier, that puts the tip of Cadillac's CT6 spear just into the starting territory of BMW's biggest luxury sedan. A plug-in hybrid model is promised that will offer 335 horsepower and 432 pound-feet of torque with double the fuel efficiency of a comparable non-hybrid CT6, but Cadillac hasn't yet announced pricing for that model. We're eager to find out exactly where the CT6 lands on the scale of high-end luxury cars in America. One thing is for certain, though: Cadillac is clearly trying pique the interest of German cross-shoppers with its top-level offering. Check out the press release below for more details from the automaker about its so-called Cadillac Touring 6 Sedan.
