GM recalls nearly 24,000 Buick Regals for brake issue

Buick is recalling 2018-2020 model year Regals to address a software defect in the braking system that would result in a loss of power assist under certain circumstances, making the brakes difficult to operate and potentially leading to a crash. In total, 23,734 models are covered by the campaign. "In the event of a partial or full loss of vacuum-brake assist, the vehicle’s hydraulic-brake boost is designed to supply supplemental pressure to the vehicleÂ’s brake system. A software error in the electronic brake control module (EBCM) may fail to activate the hydraulic-brake boost under these conditions," GM said in its defect report to NHTSA. "If the vehicleÂ’s vacuum-power brake assist partially or fully fails, braking events may require additional stopping distance, depending on the brake pedal force applied by the driver. Increased stopping distances could increase the risk of a crash." GM says that a warning indicator will illuminate in the dash if the system completely fails, and drivers may notice an increase in brake pedal resistance. Failure will not render the brakes inoperable, but they will require more force to operate. GM has begun notifying dealers of the defect; owners should be notified starting in August.   Related video: Recalls Buick GM Safety Hatchback Wagon Sedan

NFL QB Cam Newton and supermodel Miranda Kerr star in Buick's Super Bowl ad

Buick's Super Bowl LI ad is another demonstration that its cars aren't frumpy anymore. The ad opens with parents watching their children play football, with one of the dads, we'll call him "Dad No. 1," shouting encouraging words to his son. In the background, a bright red Buick Cascada pulls up, and another dad, "Dad No. 2," points it out. Dad 1 doesn't believe him, and says, "If that's a Buick, then my kid's Cam Newton." All of sudden, his son transmogrifies into Carolina Panthers quarterback Cam Newton. As expected, he quickly dominates the game, with some amusing results. At the end, when a Buick Encore shows up, the referee inadvertently turns himself into supermodel Miranda Kerr, based on apparent disbelief over what constitutes a Buick. You can see all of the shenanigans in the video above. Plus, if you'd like to see what goes into making a Super Bowl commercial, Buick produced a short video with Newton and Kerr showing what happens behind the scenes. You can check it out below.

Third 1987 Buick Regal GNX will be auctioned in January

A member of the 1987 Buick press fleet is hitting the auction block next year and it's a rarified gem: a low-mileage Regal Grand National GNX, serial No. 003 and one of just 547 models built for that year, and the last of the traditional body-on-frame, rear-wheel-drive Grand Nationals. It'll be auctioned at the Barrett-Jackson Scottsdale Auction in January. The GNX No. 003 was loaned out to publications including Autoweek, Motor Trend and Road & Track, where it racked up around 8,200 miles. "Through it all, a constant sad undertone was the understanding that 1987 was to be the final appearance of the traditional body-on-frame, rear-wheel-drive G-body (which also underpinned the best-selling Chevy Monte Carlo, Pontiac Grand Prix and Olds Cutlass)," reads a the description published on Barrett-Jackson's website. "A totally redesigned W-body Somerset Regal, with front-wheel drive and unitized body construction, was slated to replace the popular midsize Buick in 1988." So Buick opted to make "a Grand National to end all Grand Nationals" with the '87 GNX, partnering with ASC/McLaren to equip them with wheel lip flares, fender vents, 16-by-8-inch BBS rims and more aggressive tires. It left untouched the Grand National's standard Sequential Electronic Fuel Injection 3.8-liter V6 but added a larger Garrett T-3 turbocharger with a ceramic impeller, a larger intercooler, more aggressive fuel, spark and waste gate tables, and a dual exhaust system that boosted output from 235 horsepower and 330 foot-pounds of torque to 276 hp and 360 lb-ft. That was enough, Barrett-Jackson reports, to make the performance coupe quicker and faster in quarter-mile tests than the Ferrari F40 and Porsche 930 Turbo. After making the test-drive rounds in the automotive media, the car sold in 1988 as a brass hat/company official car to Fischer Buick in Troy, Mich. with approximately 8,200 miles on it. From there, it quickly sold to a local resident who drove it very little, and sold it in the spring of 1989. Since 1992, it has reportedly been kept in climate-controlled storage, totally original, unmodified and undamaged, with just 10,790 miles on the odometer today. It recently underwent a complete mechanical service and cosmetic reconditioning. You can check out the listing on Barrett-Jackson here. The first '87 GNX ever produced resides in the General Motors Heritage Collection and No. 002 is at the Sloan Museum in Flint, Mich. Interestingly, another '87 GNX, No.
