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

Chevrolet Colorado ZR2 concept suggests a diesel off-road future

"It takes the Colorado to a whole new place." – Mark Reuss The Chevrolet Colorado looks set to gain a more capable off-road version, with the company previewing a potential design direction with a ruggedized concept Wednesday at the Los Angeles Auto Show. Called the Colorado ZR2, the concept brings back the name used on off-road-tuned S-10 and Blazer models in the 1990s and 2000s. The ZR2 has a track that's four inches wider than the Colorado Z71, which is currently the line's most capable off-roader. The ZR2 is fitted with a new grille, power-dome hood, custom wheel flares and off-road-style fascia that reduces overhang and has flip-out aluminum tow hooks. It's all slathered in an outdoorsy hue dubbed Cyprus Green. The are electronic locking front and rear differentials, skid plates and mono-tube coilover shock absorbers. It all rolls (or crawls) on 275/65R18 off-road tires wrapped around custom 18-inch aluminum wheels. There's also a spare tire assembly mounted in the bed, which has a spray-in liner and 48-inch lift jack should things go afoul on the trail. "It takes the Colorado to a whole new place," Mark Reuss, General Motors executive vice president of global product development, said at the reveal. Power comes from the 2.8-liter Duramax diesel engine making 181 horsepower and 369 pound-feet of torque. This engine will arrive later in the year in the production Colorado. While the ZR2 remains only a concept, it suggests a new path for the Colorado – one we hope Chevy decides to take. Chevrolet Introduces Colorado ZR2 Concept Aggressively styled, more capable and driven by new 2.8L Duramax diesel engine LOS ANGELES – Chevrolet today introduced the Colorado ZR2 concept – a vision of how Chevrolet could take the all-new midsize truck's off-road capability to the next level. It also showcases the new 2.8L Duramax diesel engine that will arrive in the Colorado lineup later next year. The aggressively styled concept builds on the capabilities of the production Colorado Z71 and advances the legacy of Chevrolet's previous ZR2 production models. "From the bold stance to the trail-ready special equipment, the Colorado ZR2 is all about the fun of driving where the pavement ends – and doing it in characteristic Chevy style," said Tony Johnson, Colorado marketing manager.

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.
