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.

GM cancels CES date, possible Cadillac EV crossover unveiling

General Motors is bailing on CES 2020, the big annual consumer technology showcase in Las Vegas, after its plans to showcase an autonomous, electric vehicle were derailed by the 40-day UAW strike this fall. New evidence suggests that vehicle may have been Cadillac’s upcoming EV crossover. MotorTrend got GM to confirm that it was pulling out of CES, which takes place in January, though CEO Mary Barra in an interview said only that the vehicle they had planned to unveil was electric and featured autonomous technology — two key areas where the automaker plans to focus in the future. The automaker said the model simply wasnÂ’t ready. But MT said it then received an invitation from Cruise, GMÂ’s self-driving vehicle subsidiary, to an event later in January in San Francisco. That suggests the automaker could have been planning a different vehicle to show at CES than its self-driving Cruise AV “robotaxi,” which famously features no steering wheel or pedals. Cadillac showed off a digital rendering of a forthcoming unnamed electric crossover in Detroit in January, saying only that it would be available in both two- and all-wheel drive and sold globally. GM has said Cadillac will be its lead brand as GM delves into EV technology. The speculation is that the crossover will also feature CadillacÂ’s Super Cruise semi-autonomous highway driving technology. Whatever the vehicle was, or is, Barra said itÂ’ll be ready for viewing in the first half of 2020. GM has been developing the Chevrolet Bolt-based Cruise AV, a fully autonomous car, alongside its Cruise self-driving technology subsidiary, and building them at Orion Assembly plant near Detroit. It had once planned to debut a fleet of ride-hailing Cruise AV robot axis by the end of this year but realized the timeline was not realistic. Testing of the robot axis continues in San Francisco, Phoenix and Michigan. As for timing on a new timeline for fleets of Cruise AVs to take over the streets, Barra wouldnÂ’t show her hand. “We see a line of sight but weÂ’re not going to put another date out there,” she told MT, adding it was more important to “gain customer trust and usage.” As for Cadillac, any new reveal would likely come after the all-new Escalade SUV in February and amid a product blitz that will see it introduce a new or redesigned model roughly every six months through 2021.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
