GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

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.

Cadillac SRX and Saab 9-4X recalled for suspension defect

General Motors has recalled 380,498 vehicles due to rear suspension toe link adjusters that may not have been tightened properly, which could result in a loose toe link. The vehicles affected by the recall are Cadillac SRX crossovers built between 2010 and 2016, and Saab 9-4X crossovers built in 2011 and 2012. A loose toe link could cause instability while driving, especially at highway speeds. This recall follows up an investigation by the National Highway Traffic Safety Administration after it received complaints from SRX drivers of uncontrolled swaying while driving. According to the agency, two incidents led to a crash. It's possible that improper procedures for tightening a toe link nut during four-wheel alignments may have resulted in corrosion and thread wear on the adjustable portion of the link. Owners of affected vehicles are advised to park their crossovers if they experience certain Malfunction Indicator Lamp warnings on the dashboard or if they feel unusual steering behavior while driving. According to the official NHTSA recall notice, dealers will replace the adjustable toe link with a non-adjustable one at no charge. Letters are expected to be mailed to owners of affected vehicles on August 9, 2021. Alternatively, owners can call Cadillac customer service at 1-800-458-8006 or Saab customer service at 1-800-955-9007 and reference recall number N212340980. This is the second time many of these vehicles have been recalled for problems with the rear toe links. Back in September of 2014, GM announced that it would recall 290,241 vehicles that included SRX and 9-4X models because a "nut in the rear suspension toe adjuster link may not be torqued to the proper specification."
