GMC could have used Jeep's prized grille design on its born-again Hummer

General Motors confirmed it's bringing the Hummer nameplate back on an electric, GMC-badged pickup by publishing a dark photo of its front end. The battery-powered drivetrain under the sheetmetal represents a tectonic shift, but we noticed another flagrant break with tradition: it wears six slot-like inserts instead of seven like on every previous Hummer and countless Jeeps. Adding an extra slot wouldn't have landed GMC in hot water. The seven-slot grille has historically been associated with Jeep, and the company proved it's willing to go to significant lengths to ensure another automaker — especially one it perceives as a rival — doesn't use it. Parent company Fiat-Chrysler Automobiles (FCA) bitterly sued Mahindra over the Roxor's design, including its five-slot grille, and won in 2019, forcing the Indian firm to unveil a redesigned side-by-side for the 2020 model year. And yet, stylists would have very likely been able to get away with it on the Hummer. While General Motors owns Hummer, the brand traces its ancestry to 1970, when American Motors Corporation (AMC) purchased Jeep from Kaiser and changed the name of its General Products Division to AM General Corp. The division manufactured the rear-wheel drive, CJ-based DJ for the United States Postal Service and began developing the Humvee in 1979. Jeep and AM General went their separate ways when Renault began investing in AMC. Foreign companies weren't allowed to own defense contractors, and AMC had more to gain by gradually selling out to Renault than by keeping AM General, so it divested the division to LTV Corporation in 1983. Humvee production started shortly after, but no one protested its seven-slot grille because there was no risk of it stealing sales from a comparable Jeep model. It was manufactured exclusively for the U.S. Army, and civilian sales weren't planned.

It was huge, correspondingly expensive, and its portal axles made the YJ-generation Wrangler wet its pants. It's the H2 concept (pictured above) unveiled at the 2000 Detroit Auto Show that set off alarm bells in Auburn Hills. DaimlerChrysler's lawyers counted the slots in the chrome-plated insert that dominated its front end and shuddered when they reached seven.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

GM recalls 83,572 SUVs for ignition switch issue

General Motors is recalling 83,572 SUVs from the 2011 and 2012 model years over a potential ignition lock actuator issue. In affected vehicles, the actuator isn't the right size, which could cause the ignition to get stuck in the "Start" position, and then either due to a jarring event or a "cool interior temperature" the ignition could switch back to the "Accessory" position. Doing so would cause a loss of power assistance and the airbags might not deploy. This is a different ignition issue than the one that's been ongoing for the past year. GM said it expects that less than 500 vehicles suffer from the problem, but that the pool could include vehicles from 2007 through to 2014 that have already been fixed, but with defective parts. The 2011-2012 SUVs included in the National Highway Traffic Safety Administration notice: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. GM will notify owners and dealers will inspect the ignition lock housing to see if it needs a free replacement. RECALL Subject : Ignition Lock Actuator may Bind Report Receipt Date: DEC 30, 2014 NHTSA Campaign Number: 14V827000 Component(s): ELECTRICAL SYSTEM Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position. CONSEQUENCE: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury. REMEDY: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696 for the original equipment, and 14912 for the service replacement parts.
