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 Velite Plug-In Hybrid Concept debuts to little fanfare

Buick pulled the covers off its latest Velite Concept at the Auto Guangzhou 2016 show in China. We say latest because this is actually the second time Buick has used the Velite name for a concept, the previous having been shown at the 2004 New York Auto Show. The first Velite concept was a two-door convertible; the second Velite is a four-door crossover. Enough about the name, what about the concept? Well, it's very highly stylized, and we don't really mean that in a good way. There's nothing about the Velite that screams Buick, except for its badges, of course. At the front is a compressed version of Buick's traditional waterfall-like fascia. It's flanked by slit-like LED lighting elements. The rest of the face looks to our eyes like it draws inspiration from the latest Toyota Prius. There isn't a single flat element to the Velite Concept's bodysides, in a way that resembles recent concepts from Infiniti. The last bit of styling flourish are deep recesses just ahead of the rear wheels, a look that is reminiscent of BMW's i-series of vehicles. There aren't any images showing the Velite's hind quarters, but from what we can see, that also has a QX-ish look about it. There are no shots yet of the Velite's interior, but Buick says it's "elegant" and "includes recycled materials." We wish we could see what it looks like, because the automaker says it "[points] to design trends for upcoming new energy vehicles." So, the Buick Velite Concept is a nondescript mashup of design elements that we've already seen. Under the skin, however, things are more interesting. It's a plug-in hybrid with a modular lithium ion battery. That doesn't tell us much – it could be a variant of the Chevy Volt, or it could be a different system altogether. We look forward to finding out. In the meantime, have a look at the high-res image gallery up above. Oh, and if you're wondering, the word velite traces its roots back to a lightly armored military division in ancient Rome. Related Video:

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.
