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 is doing a 'second installment' of the CT6-V for $92,790

After being all but certain the Cadillac CT6 would begin pushing American daisies June 1, the brand said "the CT6 was never meant to be fully on the chopping block." The same day we got that news, Cadillac began taking pre-orders for the CT6-V. Limited to 275 units and costing $88,790 after destination, orders came in so quickly that order books closed only hours later. Turns out the phrase "275 pre-order slots" was another slight miscommunication. Cadillac has announced continued production of the CT6-V, this time costing $92,790. In February, Cadillac Society confirmed with the automaker that the 275 figure only applied to pre-orders. It isn't clear how many CT6-Vs will be built in what the brand calls the "second installment," but it is clear that buyers who didn't get in early will pay more. Cars Direct was privy to a letter sent to dealers that said pre-order buyers "were rewarded with a special introductory offer by quickly raising their hand." Those slow on the draw have hopefully used the extra time to fish another $4,000 from their pockets. The elevated price buys the same car that was $88,790 two months ago - nothing has changed but the bottom line. The new MSRP puts more distance between the hot CT6-V and the $89,290 CTS-V. Conversely, the CT6-V with a Blackwing V8 beating 550 horsepower and 627 pound-feet of torque is now just $4,000 less than the coming Platinum V8 trim, which costs $96,790. That Platinum version gets a detuned Blacking putting out 500 hp and 553 lb-ft. The vague phrase "second installment" phrase makes us think Cadillac's not committing to a number so it can cap production at will depending on how this more expensive go-round fares. Still, it's good news for anyone who wanted the sedan new and didn't hit the buzzer quickly enough in January. As if all that weren't surprising enough, GM Authority reported that there's a second-gen CT6 in development. The outlet's sources say the new sedan will move to GM's VSS-R platform, the modular architecture that will replace both the Alpha and Omega platforms. The platform initialism stands for Vehicle Set Strategy - Rear-wheel drive. The car even has a codename: 7ESL, where 7 represents the architecture, E the segment, S the sedan body style, and L the Cadillac brand. Looks like the CT6 will be nothing but surprises this year.

Cadillac scraps three-row CUV plans

Crossovers are one of the hottest automotive segments on the planet. Apparently, the idea of mixing the practicality of a station wagon with the looks of an SUV appeals to people whether they are in Cleveland or Shanghai because nearly every automaker is jumping into the market. So it was no surprise when early rumors suggested Cadillac was planning two, new CUVs to fit above and below the SRX. But things might have changed since then.
New rumblings indicate Caddy is taking a different route. Instead of two crossovers, only the compact is on the way, and the larger, three-row CUV on the Lambda platform to sit between the SRX and Escalade may be a goner. According to Ward's Auto, General Motors thinks that the other three-row, Lambda vehicles like the Buick Enclave and GMC Acadia compete too closely with the proposed Cadillac. The decision comes fairly close to the 2017 intended production date.
As far back as 2010, this Lambda-platform based CUV was considered highly likely for production. However, Cadillac Senior Vice President Bob Ferguson was somewhat cooler about it when he discussed the new crossover briefly last year. He said the model could use the Escalade name, despite its unibody chassis, but no decision had been made yet to actually produce it.
