Nissan Sentra, Buick LaCrosse to headline LA Auto Show

We're less than a month away from the start of the Los Angeles Auto Show, and automakers have been lining up their debuts for the upcoming left-coast expo. The latest announcement comes from the show's organizers who are eager to tout the global debuts slated for next month. Chief among them will be new versions of the Buick LaCrosse and Nissan Sentra. So far all we've seen of the 2017 LaCrosse is a glimpse at the front grille, but it's already promising to bring elements of the Avenir concept to the street. The original LaCrosse was launched in 2004 and was replaced in 2010 with the current model. The Sentra nameplate has been around much longer, but the current model was launched more recently in 2013. The new version spied recently while undergoing testing is promised to be a substantial update on that model, not a complete replacement, bringing it up to speed with the latest equipment and revised styling. This represents the first official confirmation we've received of when Nissan will be unveiling the new Sentra. Mitsubishi will also be on hand with its new Outlander Sport, as well as the redesigned Mirage. They'll be joined as well by new versions of a couple of high-end models that promise to resonate with the local crowds in tinseltown. Land Rover has chosen the LA show as a suitable venue to unveil the production Range Rover Evoque Convertible that will drop the top on one of the most stylish luxury crossovers on the market. And Porsche, as we know, is gearing up to hit the track with the new Cayman GT4 Clubsport - a customer racing version of the company's little two-seat, mid-engined sports car that's been lightly modified for motorsport competition. Of course these won't be the only new metal on display at the Californian auto expo. They'll be joined as well by the likes of the new Infiniti QX30, Hyundai Elantra, Kia Sportage, and Jaguar F-Pace - many of which we've already seen. Meanwhile companies like Fiat, Ford, Mazda, Mercedes, Subaru, Volvo, Volkswagen, and Elio Motors are keeping their plans under wraps for the time being. But with mere weeks to go, it won't be long before we see what they've got in store as well.

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.

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:
