Chevy, GMC and Ram dealers are worried they'll run out of new pickups

One of the unexpected side effects of the ongoing coronavirus pandemic is a shortage of pickups at Chevrolet, GMC and Ram dealers. Supplies are running out, and the factories that build these trucks remain closed. Stores across the nation began increasing incentives in March, when the first stay-at-home orders were issued, in a bid to continue luring buyers into showrooms. They also launched online sales channels, or expanded their existing digital business. Sales nonetheless plummeted in April 2020, but in-demand vehicles, like the Ram 1500 and the Chevrolet Silverado, are still selling relatively well thanks in part to the aforementioned incentives. Pickups outsold sedans for the first time in April 2020, according to The Detroit News, by 17,000 units. The problem is that General Motors, Fiat Chrysler Automobiles (FCA), and Ford temporarily closed their factories in March. "The pipeline is very dry," said Mike Maroone, the CEO of a large dealership group named Maroone USA, in an interview with Automotive News. He told the publication his Chevrolet stores are sitting on a 30-day supply of the Silverado, which is one of America's best-selling vehicles. "That is a problem for us," he concluded. Coronavirus-related lockdowns and factory closures compound problems already faced by dealerships who represent General Motors-owned brands. They entered 2020 with a thinner inventory than a year earlier due to the 40-day United Auto Workers (UAW) strike that paralyzed the company late in 2019, and the 0%, 84-month offers announced in March have sapped supply. Ram wasn't affected by a strike, but it has relied heavily on generous incentives to move trucks off lots. Ford, on the other hand, limited incentives to 2019 models. Inventory levels differ greatly from region to region. The national average for the Silverado stood at an 82-day supply in March 2020, down from 120 in March 2019. Ram stores had a 114-day supply of the 1500 (compared to 134 a year earlier), while Ford bucked that trend with a 111-day supply versus 84 in 2019. Don't panic if you're in the market for a truck; we're not facing a complete drought. Automotive News added that America's light-duty pickup inventory could fall to 400,000 units by the end of May, and drop further to 260,000 units in June. For context, there were about 700,000 light-duty trucks in stock in May and June of 2019. That's unquestionably a sharp drop, but there will still be over a quarter of a million trucks to choose from.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

GM recalls half-million full-size SUVs to address seatbelt issue

GM is recalling its redesigned full-size SUV models to address improperly riveted mounts securing the third-row seatbelts that may fail in the event of an accident. The population includes the 2021-2022 Cadillac Escalade and Escalade ESV, 2021-2022 Chevrolet Suburban and Tahoe, and 2021-2022 model year GMC Yukon and Yukon XL, for a total of 484,155 vehicles. "Operators at the supplier’s manufacturing plant may have not properly followed manufacturing processes and inadvertently missed the rivet forming operation," GM said in its defect report to NHTSA. "In certain of these vehicles, the rivet that retains the buckle to the mounting bracket in the left or right side third-row seatbelt buckle assembly may not have been properly formed during the manufacturing process. If the third-row seatbelt assembly is not properly riveted, it may not properly restrain occupants in a crash, increasing the risk of injury." Fortunately, the fix is relatively simple. GM service technicians will inspect the rivets on the rear seatbelt buckle assemblies and replace the entire unit if the rivets are not to spec. Dealer notifications have already been distributed; owners should receive notice start in September. Related video: Cadillac Chevrolet GM GMC Ownership Safety SUV
