Chevy Colorado, GMC Canyon get updated tachometers due to graphical error

After James Bearing bought a Chevrolet Colorado, he noticed a discrepancy between the truck's spec sheet and the truck's tachometer: Chevrolet said 3.6-liter V6 in the little pickup produces 305 horsepower at 6,800 rpm, but the the tachometer indicates a redline at 6,500 rpm. So either he wasn't making as much power as he was promised, or the tachometer display was incorrect. Bearing said he asked Chevy about it but got no response. Until now. A General Motors spokesman said the rev limiter is indeed set for 6,800 rpm, but the tach graphics "are slightly off" in the Colorado and the GMC Canyon, and submitted an SAE horsepower certification to back him up. If you're wondering how such a thing got past quality control... well, let's just say you're not alone. GM is going to fix "the graphics on future trucks," which makes it sound like Bearing will just have to learn to live with the indicated redline he's got. He could always pretend he's driving a sleeper, with four more ponies waiting to be unlocked in the danger zone for those who dare.

It's possible to go 111 miles on electricity in the new Chevy Volt

Wayne Gerdes at CleanMPG put the 2016 Chevrolet Volt in Premiere trim through a few closely watched on-the-road tests over a few days. One of them was a run from full charge to EV-only exhaustion, and at the end of the trip Gerdes had traveled 111.0 indicated miles on a single charge, 111.9 according to his Garmin. What's the catch? He guessed his average speed was about 20 miles per hour, which was 15 and 20 mph around town and "a few miles" at 50 mph on the highway. The EPA says the new Volt should go 53 miles on battery power. In the 2011 Volt, rated at 38 electric miles, Gerdes got 75.5 miles on a charge. The upshot is that at urban driving at average speeds should get drivers the EPA rated 53 e-mpg without fuss. He wasn't so impressed with performance in Charge Sustaining Mode, though. During one run that covered 101.2 actual miles in CSM, using 1.691 gallons, the Volt got 59.8 mpg. Speaking of driving in CSM only, Gerdes said it's less efficient here than in competitors from Toyota, Honda, and Hyundai, but that's one of the few performance-related complaints he had. Elsewhere around the PHEV, Gerdes liked improvements to the eight-inch display and rear-view camera, build and design quality, the much quieter ride, and the switch to regular fuel. The six-foot Gerdes found the cabin space still cozy, especially in the back where ingress and egress could be a challenge for people of a certain stature. He lamented the fact that he couldn't find instantaneous fuel and energy consumption or among the many readouts, and would prefer the sedan kicked into glide mode sooner. In spite of that, he declares the Volt II "a full blown electric car." Head over to CleanMPG for the rest of his assessment.

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
