Cadillac Super Cruise gets system enhancements, more compatible highways

Cadillac is updating Super Cruise to make it available to use on more highways, and it will offer better performance, too. Previously, Super Cruise worked on about 130,000 miles of highways across the continent. This update expands that to 200,000 miles. That's because GM has mapped that many more miles to be compatible with its lidar mapping system. As for the performance update, Cadillac says there will be enhancements to the driver monitoring system. That's the key feature that separates Super Cruise from all the other systems out there, making it a truly hands-free experience. It's able to quickly tell whether your eyes are on the road, and it reacts accordingly. We asked for details about the improvements, but all Cadillac would tell us is that there are "slight refinements to the driver attention system to even more accurately detect driver attention." Perhaps it's related to reports of sun-related issues plaguing the infrared monitoring camera. We can't tell you for sure. As for the extra miles, Cadillac says some added highways now include limited intersections and traffic control devices. Basically, there may be a stoplight or some cross traffic thrown into the mix now. Since GM has actually gone and mapped these areas, the car will tell you to take back control when approaching a railroad crossing, pedestrian crossing, stoplight or stop sign. Cadillac included a map (above) depicting the original and new Super Cruise compatible highways. You'll notice there are a lot more highways in the midwest and southeast, in addition to almost being able to cross the entirety of Canada now. Things are still a bit sparse in the western part of the country, but there aren't as many highways out there anyway. Owners of 2018 and 2019 Cadillac CT6s can expect to get the upgrade, but it's not as easy as you may think. Folks will have to take their CT6 in to the Cadillac dealer, where the "system enhancement" will take place. However, that enhancement doesn't include the additional miles. Cadillac says that update will be sent out over-the-air throughout the summer and fall. Updates for Super Cruise seem to be coming out with regularity. Last year Cadillac updated the system for easier activation, better lane placement (for passing large vehicles) and added gauge cluster messages for more information. We happen to love using the technology here at Autoblog, and gave it our 2019 Technology of the Year award.

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.

Watch the 2014 Cadillac CTS get its groove on in the rain

In case you haven't got enough of the 2014 Cadillac CTS that just debuted at the New York Auto Show, Cadillac has let us have some rolling footage of the car around its test track along with a few words from VP of marketing Don Butler and executive director of design Mark Adams.
You won't learn much more about its 420-horsepower, twin-turbo V6 but you can hear how it growls in the rain, and you can get a better idea of how you'll look in the driver's seat giving it a workout. That's got to be worth something, right? You'll find both videos just below.
