GM recalling 117,000 sedans, crossovers, SUVs, pickups and vans

General Motors has issued a stop-sale to dealers and has notified the National Highway Transportation Safety Administration of its intention to recall 117,000 vehicles in the United States, Canada and Mexico. Of those vehicles, only 4,500 are at dealerships.
The affected vehicles include the Cadillac CTS and Chevrolet Impala sedans, fullsize SUVs (Cadillac Escalade, Chevy Tahoe and Suburban and GMC Yukon and Yukon XL), Lambda-platform crossovers (Chevy Traverse, Buick Enclave and GMC Acadia), heavy-duty pickups (Chevy Silverado HD and GMC Sierra HD) and fullsize vans (Chevy Express and GMC Savana). The sedans and body-on-frame SUVs include model years 2013 and 2014, while the CUVs, heavy-duty pickups and vans are limited to MY2014.
GM confirmed the recall to Autoblog via an emailed statement (which we've included below). According to the statement, the issue at hand in what is the company's 69th recall of 2014 covers the chassis-control module. Automotive News is reporting that a problem in the chassis-control system could cause a short in the module, which could cause the engine to stall or fail to start. The fault could also affect the trailer-brake control, provided it's equipped.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

President Trump's new limo spotted testing at high speed

What you're looking at is no ordinary limo. Look past the swirly camouflage and you'll see what appears to be a Cadillac, but don't let those looks fool you. This is the new Beast, otherwise known as Cadillac One, and codenamed by the Secret Service as Stagecoach. This is the car that will shuttle President Trump to and fro. It's hard to get a sense of scale from these images, but this car is huge. It's very likely built atop a heavy-duty truck platform, which is necessary due to the thick armor-like bodywork that's hermetically sealed to keep POTUS safe and sound. It's hard to tell for certain, but it appears this Beastie is riding on Goodyear Regional RHS II tires, which would otherwise be used on trucks and buses. Translation: this thing is heavy. The Beast is ostensibly badged as a Cadillac, and it wears the latest version of Caddy's corporate grille, badge, and upright headlamps at the front. From the rear, there's a hint of Rolls-Royce Phantom, with rear glass that tapers elegantly into the deck lid. In between is a massive slab-sided passenger compartment that's rumored to seat as many as seven passengers. These shots were snapped at GM's Milford Proving Grounds. It seems The Beast is undergoing some high-speed tests, though high-speed here is relative. Those Goodyears are only rated for 70 miles per hour or so, and we doubt the big 8.1-liter gasoline-fueled V8 engine is geared to push the President much faster than that, anyway. Related Video:
