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 patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Junkyard Gem: 1985 Chevrolet Sprint

For in the 1985 model year, General Motors began selling Chevrolet-badged Suzuki Cultus hatchbacks in California. Sales of the cheap three-cylinder econobox in the rest of North America followed soon after (with the Canadian version known as the Pontiac Firefly), and did pretty well considering the crash in gasoline prices during the middle 1980s. Starting in 1988, the facelifted Sprint became the Geo (and, later on, Chevrolet) Metro. Here's one of the very first Cultuses sold on our shores, found in a San Francisco Bay Area car graveyard. Amazingly, the primitive rear-wheel-drive Chevrolet Chevette remained available all the way through 1987, competing with the thriftier front-wheel-drive Sprint in the same showrooms. For 1988, Pontiac started selling a rebadged Daewoo LeMans, so the Sprint/Metro never lacked for intra-corporate competition. Inside, you'll find the same stuff most mid-1980s Japanese econoboxes got: tough cloth upholstery and long-wearing hard plastics. Suzuki quality in 1985 wasn't quite up to Honda or Toyota levels, but you weren't paying Honda or Toyota prices for the Sprint. MSRP on this car started at $4,949, or about $12,000 in 2020 dollars. The cheapest possible 1985 Chevette cost $5,340, while a new no-frills Ford Escort would set you back $5,620. Subaru, however, could have put you in a punitively unappointed base-model Leone hatchback for just 40 bucks more than the Sprint that year. I think I'd have sprung the extra for a $5,348 Toyota Tercel, a $5,195 Mazda GLC, or— best cheap-commuter deal of all that year— the $5,399 Honda Civic 1300 hatchback. I was 19 years old and driving a Competition Orange 1968 Mercury Cyclone that year, and I recall feeling pity for Chevy Sprint drivers, new-car smell or not. Still, these weren't bad cars for the price, though a Sprint with an automatic transmission was a real character-builder. Got three cylinders and uses 'em all! 48 horsepower from this hemi-headed SOHC 1-liter. The Turbo Sprint — yes, such a car existed — had a howling 70 horsepower. The hood-latch release is a rectangular button that resembles a badge. 1985 Chevy Sprint Commercial The highest-mileage, lowest-priced car you can buy. 1985 holden barina commercial The Australian-market version was the Holden Barina, and the TV ads featured the Road Runner. 1983 SUZUKI CULTUS Ad In its homeland, this car got screaming guitars and a drive through New York City for its TV commercials.
