GM recalls Chevy Impala, Cadillac XTS for braking problem

Back in April, General Motors launched an investigation into braking issues affecting the 2014 Chevy Impala. Now there's a recall of both the Impala and the Cadillac XTS with which it shares its Epsilon II platform.
The issue apparently revolves around the electronic parking brake, which may not properly disengage. As a result, the rear brake pads could rub the rotor even while the vehicle is in motion, causing "significant heat, smoke and sparks." The earlier investigation had been launched following a complaint regarding the forward collision avoidance system, which is now either appears to have been unrelated or possibly a symptom of this larger issue.
The recall affects 2013-15 XTS models manufactured between February 14, 2012, and August 22, 2014, as well as 2014-15 Impalas manufactured between January 15, 2013, and August 22, 2014. The total number of affected vehicles reported by the National Highway Traffic Safety Administration comes to precisely 132,921 units, while The Detroit News reports a higher total of 205,000 units - the difference potentially coming down to the scope within the US and more broadly across North America. Dealers will contact owners to update the software in order to fix the problem.

2016 Cadillac CTS-V First Drive [w/video]

A million insects lost their lives today. Boxelder bugs and mayflies making the ultimate sacrifice in Elkhart Lake, their carapaces no buffer against a rocketing rectangle of safety glass. Their bodies gorily streaking into spangles along the diamond-faceted face of the Cadillac CTS-V. Road America is a four-mile ribbon of pavement snaking its way through the emerald center of the country's northern heartland. Since the 1950s it's seen uncountable fields of diverse racing machinery rocket over its hills and around its 14 corners. I would imagine that on those occasions the tramping of onlookers and hubbub of vehicles, both competitive and commonplace, would dissuade a great number of our six-legged friends from making their way onto the track. But today it's just me turning laps. Inconceivably just one journalist, driving the baddest roadgoing Cadillac ever made, on one of the loveliest circuits America has ever carved out. So big-winged bugs made it out to me in a vast array and a tragic sum, and I drilled through them oblivious to anything but one of the greatest days of driving I've ever had. Cadillac has turned its CTS-V from a performance sedan to a monster. For 2016 Cadillac has turned its CTS-V from a performance sedan to a monster worthy of the carnage described above. The words "epic" and "awesome" are hilariously overused on the Internet, but in the case of the CTS-V's 6.2-liter supercharged V8, their literal meanings are fitting. The capacity to produce 640 horsepower and 630 pound-feet of torque is astounding. Feeling those outputs come to growling life under my foot arch, uncorks different reactions in my brain as the day wears on: first trepidation, next cautious optimism, finally red-eyed bloodlust. A glance at the power and torque curves will show you that the charged V8 behaves more like a naturally aspirated thing than a turbo'd on/off switch. Peak torque arrives at 3,600 rpm, horsepower at 6,400, giving the engine lovely, linear power delivery. Even with top torque happening near the middle of the tach, there's no small amount of the stuff when the engine first spins up, so launching all 4,145 pounds of Detroit iron still feels exotic. Launching all 4,145 pounds of Detroit iron still feels exotic. On the roads around Wisconsin, using all of the available power is hardly advisable, but I have no trouble driving this fast car slowly (sort of).

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.
