GM recalls nearly 340,000 large SUVs to fix daytime running lights

General Motors has initiated a recall campaign for more than 338,000 of its large SUVs to address a potential defect in the onboard computer software that controls the daytime running lights. In some cases, the DRLs may remain on even when the headlights are enabled, which creates additional glare for oncoming drivers at night and fails to comply with federal regulations for headlight performance.  "GM determined that the body control module (BCM) software in these vehicles, under a combination of certain pre-conditions, may fail to deactivate the DRLs when the headlamps are on," GM's recall report said. "A regulatory assessment was conducted to evaluate whether the condition presented a potential noncompliance with the DRL activation requirements in S7.10.5, Table I-a. of FMVSS 108. On October 27, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a recall for potential noncompliance with this standard." GM says the recall covers the 2021 model year GMC Yukon and Yukon XL, 2021 Chevrolet Tahoe and Suburban, and 2021 Cadillac Escalade and Escalade ESV. The company says all models produced within that operating window include the improperly programmed body control module, meaning all vehicles within the recall population may exhibit the problem. The issue was discovered by a GM engineer during validation testing in August, prompting a deeper investigation and eventually leading to the recall itself.   The module's software can be updated by GM dealers, so it should be a quick fix for customers. Notifications will be mailed to owners in December.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety SUV Luxury

Cadillac XT5 confirmed for 2016 as next-gen SRX

Cadillac's entire lineup of 2016 models gets a major infotainment upgrade this summer with improvements to CUE and integration with Apple CarPlay and Android Auto. There's one major exception for now, though. The SRX retains the old system until its all-new generation, called the XT5, debuts early in the 2016 calendar year. "When we transition into all new product lines, we will evolve the naming convention to suit the new classification we have announced. So SRX becomes XT5 next year," company spokesman David Caldwell said in an email to Autoblog. Earlier spy shots and rumors suggest the XT5 might be offered with a turbocharged four-cylinder and naturally aspirated six-cylinder engines, plus a nine-speed automatic transmission. For the rest of Cadillac's models, CarPlay arrives with the launch of the 2016 vehicles, and Android Auto joins later. Using either of them requires a connection via USB, and they add a new projection icon on the CUE screen. Once activated, both systems integrate with driver's phone and incorporate features like navigation, music, and contacts. They can also accept voice commands. Even for those that don't want to hook up a smartphone, CUE should work better thanks to a more powerful processor. Start-up times for the infotainment system are expected to be faster, and Cadillac claims that it's also more responsive for voice recognition, navigation searches, and media. The navigation interface is simplified, as well. The Escalade, CTS, and XTS can now be ordered with a 360-degree camera system to display on the screen. Cadillac Enhances Phone Integration for 2016 Models with Apple CarPlay, CUE Upgrades APPLE CARPLAY AVAILABLE AT LAUNCH; ANDROID AUTO COMING LATER IN MODEL YEAR 2015-06-09 NEW YORK – Cadillac's 2016 model year products will feature enhanced connectivity and control, including the addition of Apple CarPlay and Android Auto, the predominant new systems for in-car phone integration. These additions are part of a broader enhancement of CUE, Cadillac's user experience, with new features and a faster, streamlined operation. Apple CarPlay will debut in 2016 Cadillac models featuring CUE's 8-in multi-touch screen except the SRX Crossover, a model that will move to an all-new generation in early 2016. Android Auto is expected to be phased into 2016 production at a later date. The 2016 model year will begin this summer.

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.
