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

Junkyard Gem: 2006 Buick Lucerne CXL

When The General's Buick Division axed the LeSabre and Park Avenue names in 2005 (after 46 and 30 years, respectively, though the Park Avenue returned a few years later in China), the replacement top-of-the-line Buick sedan became the new Lucerne. It wasn't the Buick with the biggest price tag that year— those honors went to the Terraza minivan and Rainier SUV— but it became the flag-bearer for a bloodline of cushy, prestigious Buick sedans that stretched all the way back to the early days of the American auto industry. Lucerne sales for the 2006 and 2007 model years went pretty well, and now enough time has passed that some of these cars are showing up in the self-service car boneyards I frequent. Here's a first-year example with the optional Northstar V8 engine, found in a Northern California yard last summer. Plenty of American cars have been named after cities in Italy, France, and Spain, but the Lucerne is the only one I can think of that bears the name of a Swiss city (to be fair, the entire Chevrolet Division is named after a Swiss man, so Switzerland didn't really get shortchanged by The General in the naming department). CXL was the Lucerne's mid-grade trim level, sandwiched between the CX and CSX. The high-zoot Lucerne CSX got the 4.6-liter Northstar as standard equipment, but this quad-cam V8 and its 279 horses cost extra on the CXL. The base engine for the CX and CXL was the good old 3.8-liter pushrod Buick V6, rated at 197 horsepower. No US-market 2006 Buick could be purchased new with a manual transmission; this car has a four-speed automatic. In a Buick tradition stretching back to the late 1940s, this car boasts flashy "Ventiports" on the fenders. In past years, the number of ports on each side designated the car's intended swank level; starting with the Lucerne, they indicated the number of engine cylinders. So, when you're crawling around your local Ewe Pullet and looking for Northstars, seek out the Lucernes with the four-hole Ventiports. "Leather-appointed" power bucket seats and "wood-toned" trim were standard on the CXL, as well as an MP3-capable CD player with six speakers. By 2006, most American vehicle shoppers seeking something big and luxurious chose trucks and truck-like machines, but the market still supported quite a few sedan models such as the Lucerne. Most US-market GM vehicles got these little square "Mark of Excellence" fender badges during the late 2000s.

MotorWeek remembers the nearly forgotten Buick Reatta

The Reatta was Buick's failed experiment to take on European competitors with its own two-seat luxury coupe and convertible. The model only lasted a few years, and US customers didn't see another droptop from the brand until the Cascada. The latest MotorWeek Retro Review takes a look back at the short-lived roadster and remembers it quite fondly. Host John Davis calls the 1990 Reatta droptop "one of the best looking convertibles ever." His sentiment seems a little hyperbolic, but the roadster is definitely an attractive machine by the standards of the time. The smooth front end and pop-up headlights are reminiscent of Japanese sports cars of era, and the profile with the top down is elegant. There are weaknesses, though. The manual roof mechanism appears cumbersome to operate, and the crude digital instruments, which simulate physical dials, make the cabin look too dated. Other than a complaint about over-boosted power steering, MotorWeek enjoys how the Reatta drives, too. Buick's roadster is largely forgotten today, but such glowing praise suggests it deserves to be better remembered. Check out this Retro Review to look back on this interesting experiment from the early '90s. Related Video:
