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.

Buick's Velite 5 is a rebadged Chevy Volt for China

There's nary a mention of the famous Chevy Bowtie badge in Buick's press release for its new Velite 5. No shoutouts to the extended-range Volt, with which the Chinese-market Velite clearly borrows its hybrid gasoline/electric technology. But that's okay; to borrow an adage, if it looks like a duck, swims like a duck, and quacks like a duck, it's probably a duck. And, as you can see from the image above, the Buick Velite 5 is a duck Volt with a Tri-Shield badge. The Velite 5's 1.5-liter engine and lithium ion battery pack provide up to 466 miles of range, with the first 62 miles or so coming on battery power alone. That's more range than Chevy quotes for the Volt, so we're not sure what methodology Buick is using to calculate mileage. Still, even if it's more like the Volt's estimated range of 53 real-world miles, it would be enough for many Chinese drivers to avoid the gas station altogether. Buick showed off a Velite Concept late last year that doesn't appear to share much at all with this new Volt-based production model. But since the brand is promising more plug-ins and EVs in the coming years, we wouldn't be surprised to see further models carrying the Velite moniker, perhaps one based on the all-electric Chevy Bolt EV.

Junkyard Gem: 1957 Buick Special Riviera Sedan

While I find plenty of 1950s Detroit cars in quick-inventory-turnover self-service wrecking yards during my travels, they tend to be the ordinary post sedans that were built by the millions during the heyday of the three-on-the-tree manual transmission and nuclear-attack symbols on car radios. The more sought-after convertibles, coupes, and four-door hardtops are tougher to find in such yards, which makes today's 1957 Buick Special Riviera in a yard in northeastern Colorado an A-List Junkyard Gem. During the late 1950s, the Special ranked at the bottom of the Buick prestige hierarchy just below the more upscale Super and Century. Of course, this was the era of Alfred Sloan's "Ladder of Success" and the lowliest Special outranked even the nicest Olds Ninety-Eight on the Swank-O-Meter. If you were the Buick-driving Joneses and your neighbors had proletarian Chevrolets, aspirational Pontiacs, or petit-bourgeois Oldsmobiles, they were failing to keep up with you… but then you'd see a new Cadillac and feel intense envy for your victorious rival. The Ladder of Success collapsed later on, when the top-trim-level Chevy Caprices began to compete against their Cadillac Calais big brother, but it was still standing tall in 1957. The Riviera name ended up being used for its own distinct model starting in 1963 and continuing nearly into our current century, but in 1957 it was a trim level designation, used to indicate a Century or Special sedan with the then-radical pillarless hardtop design. This car listed at $2,780, which comes to a cool $27,630 in 2021 dollars. That price included the 364-cubic-inch (6.0-liter) Buick Nailhead V8 engine, rated at 250 horsepower and enough torque to peel 1957's rock-hard bias-ply tires right off their rims. The Special had a three-on-the-tree column-shift manual as standard equipment, but the original buyer of this car sprang for the extra $220 ($2,185 today) to get the Dynaflow transmission. While the shift indicator looks just like the ones on GM cars equipped with the two-speed Powerglide, the Dynaflow was an odd beast used only in Buicks; while it had gears for two forward speeds, the driver had to select low gear manually. Otherwise, a complex torque converter rig provided an experience something like today's CVTs (though with better smoothness and much more wasted power), in which the car stayed in high gear all the time and used the torque converter to multiply as needed.
