GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:

2018 Lincoln Navigator vs luxury SUV rivals: How it compares on paper

The all-new 2018 Lincoln Navigator is an impressive, luxury-lined beast. However, while its Black Label interior stood out most during our first drive of the new Navigator, it also seemed pretty clear that much of this full-size SUV was superior to the competition in a number of fundamental ways. Its Raptor-sourced 3.5-liter V6 had class-leading power for one, and its third-row seat seemed as spacious and comfortable as its rivals' are cramped and barely usable. To search for your next new vehicle, try Autoblog' s Car Finder. Yet, I wanted to take a closer look at how the Navigator fully compares on paper to its competitors - especially the Cadillac Escalade with which it most directly competes. The below spreadsheet should tell the whole story, but as you can see, there's an awful lot of class-leading green highlighter in the Navigator's column. The cargo volume and third-row legroom numbers are particularly telling, with the latter actually going up to 42.3 inches when you slide the second-row fully forward. Now, a few things to note about the above spreadsheet. The GLS-Class is also available as the GLS 550, which boasts a 4.7-liter V8 that just comes up short to the Navigator with 449 horsepower but has to deal with only 5,578 pounds. Its $94,950 price tag is comparable to the Navigator Black Label. Much of the LX 570's information is also applicable to the Toyota Land Cruiser, which, badge aside, could certainly be considered a member of this segment given its feature content and still-hefty price tag. It has better ground clearance and approach/departure angles than its Lexus sibling, along with an as-indicated lower price. Much of the Escalade's information also applies to the GMC Yukon Denali, while the Infiniti QX80 is applicable to the Nissan Armada.

2020 Cadillac CT5 prototype shows off more lighting details

The elusive 2020 Cadillac CT5 luxury sports sedan has once again been spotted by a spy photographer. This time, we get to see it from all angles, whereas last time we only saw it from the front. It still has quite a bit of fake body work, and it's very clear Cadillac still hopes you'll think this is a Charger, from the big hood scoop to the fake full-width taillights. Digging past those misdirects, we can find some new details about the car. First, the car's front lighting has developed further. There are production-ready headlights fitted that appear to have some sort of LED illumination. These production lights also fit the shape we saw on the last prototype, so they'll end high up on the body, extending slightly horizontally toward the grille. There's still a section that extends back along the fender, seeming to bridge the gap between current Cadillacs and the Escala concept from which this car takes inspiration. Another addition are the vertical LED accent lights. This is another trademark feature of both current Cadillacs and the Escala, but they were absent from the last prototype we saw. We also get a look at some of the grille's details. Instead of slats, this CT5 has a plastic mesh of small rectangles. The pattern is reminiscent of brickwork. These photos also give us our first look at the back of the CT5. It looks like a fairly typical Cadillac. It's much more conservative than the front end. There are some angular cutouts in the bumper to allow exhaust gases out. The taillights have the current Cadillac look with the top curving over the rear fender. We can't tell if there will be a horizontal element like on the Escala, due to the fake lights. We're expecting the CT5 to be shown sometime next year in time for the 2020 model year. Odds are it will use off-the-shelf Cadillac engines including the turbocharged 2.0-liter four-cylinder, naturally aspirated 3.6-liter V6, and the twin-turbo 3.0-liter V6. Now that Cadillac has revealed its twin-turbo 4.2-liter V8, we'll be interested to see if that shows up in a future CT5-V.
