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

GM will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

Bosch builds an infotainment system that just might not suck

As far as we've come with in-car infotainment and interfaces over the past decade or so, we still have a long way to go — as most current systems show. Whether it's high-end brands like Mercedes-Benz with its kludgy COMAND system, which we hope will be replaced with the MBUX platform revealed at CES, or more mainstream vehicles like Hondas (with their frustrating, knobless Display Audio interface), getting the kind of content and ease of use in the car that we're used to having on other connected devices is far too complex and sometimes costly. While Apple and Google have tried to ride to the rescue with CarPlay and Android Auto, respectively, they're limited solutions. No automaker or tech supplier has been able to deliver an easy, economical, flexible and non-distracting infotainment solution. But Bosch could be closing in on this elusive goal, given the digital cockpit concept demo I recently received at CES. Displayed in a Cadillac Escalade, the concept featured five interconnected color screens: one in the instrument cluster, two in the center console, and two more in the front-seat headrest for second-row passengers. The digital cockpit concept demo had cool features such as haptic-feedback touch-screen controls that created an edge-like feeling similar to a physical button, facial recognition to confirm driver credentials, and the intelligence to know the location of a phone in the car to lock it out to keep the driver from texting. The most significant aspect of the Bosch digital cockpit concept wasn't visible — but shows the company's vision for a future of seamless, convenient, cost-effective and safe in-car infotainment. It's powered by a single electronic control unit (ECU) that can simultaneously run multiple operating systems and also separates vehicle and infotainment controls for critical safety and cybersecurity reasons. Most modern cars can have as many as 100 separate ECUs, Philip Ventimiglia, product manager for Bosch Car Multimedia North America, explained at CES, and several just for infotainment functions. "The goal is to reduce that to about 10 so that we can save cost throughout the vehicle and enable new technologies," he added. "OEMs want to put more technology into cars, but it costs money," Ventimiglia said.
