GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

2021 Cadillac Escalade shown inside and out in leaked photos

Fresh off the official reveals of the all-new 2021 Chevrolet Suburban and Tahoe, here come leaked images showing the redesigned version of their upmarket sibling, the Cadillac Escalade, inside and out. The images were posted on Instagram by user @allcarnews, with a hat tip to Jalopnik, and give us our best look yet at the unadorned exterior and the new interior.           View this post on Instagram                       A post shared by A L L C A R N E W S (@allcarnews) on Dec 11, 2019 at 12:22am PST Let’s start with the body design of the large luxury SUV, with bears strong echoes of both the aforementioned Suburban and Yukon, albeit with a chrome stripe along the lower doors and chrome trim framing the windows. Then thereÂ’s the redesigned grille, which looks like a larger-maw version of the XT6Â’s grille and adopts the same horizontal LED headlights. Instagram commenters also liken the exterior to the new XT6, CadillacÂ’s smaller three-row crossover, and even the Hyundai Palisade. The swept-back, slightly tapered rear end in profile even reminds us a little of the Lincoln Aviator. All of which will beg the question of whether Cadillac has done enough to distinguish its flagship SUV to compete against the Lincoln Navigators of the world.             View this post on Instagram                   (UPDATED) LEAKED: 2021 Escalade ? _____________________________________ [12/11/19] (NEW INTERIOR SHOTS) CadillacÂ’s Escalade for 2021 has been leaked and well.. the exterior is subjective.. What I will point out is the side profile which is unfortunately still identical to the Tahoe & Suburbab albeit with a chrome bar on the bottom and chrome window frame trim. The rear gets full sized LED verticals taillights again, but now more integrated into the rear. The front is big and loud but looks like a blown up XT6. After reading your comments, it seems a mixed bag, especially with the horizontal headlights (which i lightened to show the elements) but the massive verticals LED DRLÂ’s remain thankfully. ???????????? ???????????? ???????????? ????????? ? @Allcarnews Spec Sheet: Powertrain wise there will be a carry over 6.2L 420HP+ V8 paired to a 10 speed auto gearbox. A supercharged V8 version (or TT V8) will be coming in the future with up to 650HP in some sort of V designation. Expect blacked out wheels, trim and grille. ? ???????????? ???????????? ??????????? But..

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
