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:

eBay Find of the Day: 1981 DeLorean with 570-hp twin-turbo Buick V6 [w/videos]

"Are you telling me that you built a time machine... out of a DeLorean?" So asked one Marty McFly of his mentor Dr. Emmett Brown, who replied: "The way I see it, if you're gonna build a time machine into a car, why not do it with some style?"
Doc Brown was right, of course: with an exotic mid-engine layout, gullwing doors and stainless steel body, the DeLorean DMC-12 sure looked the part. It just needed a little more juice. Well this one might not have 1.21 gigawatts of time-bending power - that'd be more than one and a half million horsepower - but it does have more than the 150 hp in the the standard 2.8-liter V6.
That's because this particular DeLorean has had its stock Peugeot Renault Volvo engine swapped out for a Buick-sourced, all-aluminum, 4.3-liter V6 from the Grand National. Dutteiller Performance didn't leave the engine in stock form, either: while they were swapping it out, they added a pair of turbochargers, new pistons, crank, cams and much, much more.

Buick begins offering 24-hour test drives

Even as the year's sales charts show a decline, Buick says its brand image is improving. To bolster that soft metric while it works on overhauling its lineup - consumers are clamoring for more crossovers - the brand will begin offering overnight test drives as of July 23. Buick trialled the program in Phoenix and got a good response, so it rolls out as an ad-supported nationwide campaign called "24 Hours of Happiness" as of July 22. The push is on probation for three months while Buick evaluates it, but they expect it to continue beyond 90 days. Cars will be sourced from the loaner fleets that dealers offer customers whose cars are in for service, so only dealers with such fleets will be able to participate. General Motors did the same thing in 2003 and 2004, at the time saying it led to more than 500,000 "extended" test drives and close to 190,000 sales. That program had a cash component, in that buyers were offered $250 if they chose a non-GM vehicle after their test drive. 24 Hours of Happiness won't come with any inducements; Buick is taking the long view, positioning this as support for the brand instead of as bait for immediate returns. The Phoenix dealer who ran the program first said that it got fewer bites than he expected, but that customers who took a car home "were far more likely to buy the vehicle."
