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.

Corvette's Performance Data Recorder headed to other cars, will Cadillac ATS-V be first?

For 2015, the Chevrolet Corvette Stingray gained a novel piece of high-performance technology: The Performance Data Recorder. This trick system combines video from a front-mounted camera with in-car data and GPS information to help drivers record and study their lap times, complete with data overlays. While it's a clever tool for track days, it's also finding popularity as a built-in dash cam of sorts. To this point, the technology has been a Corvette exclusive, but General Motors' executive vice president of global product development, Mark Reuss, has confirmed to Autoblog that it will soon be available in other vehicles.
At a media luncheon on Thursday, we asked whether GM was keen to expand usage of the technology to other models, and if we could expect to see something soon. Reuss coyly replied, "What's soon?" When we suggested the 2016 Cadillac ATS-V (which is scheduled to debut at next week's LA Auto Show), he replied, "There will be other uses, and it won't be that far away. How's that?"
Certainly not an outright confirmation, but we wouldn't be at all surprised to see the next high-po Cadillac roll under the klieg lights at the Los Angeles Convention Center next Wednesday brandishing more than just 450 horsepower.

2020 Cadillac CT5-V, CT4-V to be revealed next week

Even though the ATS-V and CTS-V are on the way out, the future is looking bright for Cadillac's high-performance sub-brand. Why is that? Well we're going to see not one, but two all-new V models on May 30. The company revealed its plans to show the 2020 Cadillac CT5-V and the CT4-V in an announcement about 15 years of the V brand. Not much is known about either car, but both should be wickedly quick based on their predecessors. We're particularly curious as to what engines will be used. With the CT5-V, a return of a supercharged pushrod V8 seems possible considering the CT5 is based on the Alpha platform that also underpins the Camaro. But Cadillac may want to push its more unique powertrains such as the twin-turbo, double-overhead-cam 4.2-liter V8 in the CT6-V. In the CT6-V, it makes 550 horsepower and 627 pound-feet of torque. Cadillac's former CEO said that other cars getting the engine will have it 500 horsepower and 553 pound-feet of torque. We think the company could get away with the full power in the CT5-V, though, since each car's mission and character is different. There's also a slim chance we could see a return of the manual transmission for the midsize sports sedan, based on what a Cadillac engineer said. As for the CT4-V, there are more questions, simply because we haven't even seen the regular version yet except in spy shots. Since the CT5 is built off the Alpha platform, it seems reasonable to think the CT4 will do the same, especially since the ATS also used the platform. And to leave space between the CT5-V and itself, using a hot version of the twin-turbo 3.0-liter V6 seems like the most likely choice. The hot V6 in the ATS-V made 464 horsepower and 445 pound-feet of torque, so we would expect the same. Hopefully Cadillac will offer a manual with it again. One final note from the Cadillac V announcement also got our attention. It said that these two cars are "just the beginning." That seems a pretty obvious sign there are other V models in the works. Since the CT4 and CT5 will round out the company's car line, the logical next choice would probably be crossovers. It will be interesting to see what an XT4-V or XT5-V will be like, especially since they use front-drive platforms. But in the meantime, we'll look forward to Cadillac's hot sedans.
