GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

GM recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:

Junkyard Gem: 1998 Cadillac Catera

Every so often, during the last few decades of the 20th century, the suits running each of the big Detroit automakers would eye their European subsidiaries and decide that some car from the other side of the Atlantic could be making dollars over here in addition to pounds or francs or Deutschmarks over there. Chrysler didn't do so well with Simca 1204s or Plymouth-badged Hillman Avengers in the American marketplace (though the Simca-based Omnirizon did very well). Ford USA moved quite a few Capris and Fiestas during the 1970s, then bombed with the Merkur Scorpio and XR4Ti. General Motors tried, over and over, to get Americans to buy Opels (some sold by Buick dealers, others actually badged as Buicks), and I still see the occasional Kadett, GT, or Manta in junkyards to this day. For the 1997 model year, still stinging from the not-so-great sales of the Turin-Hamtramck-built Cadillac Allante, GM took the Omel Omega B and applied Cadillac badges. The result was the Catera, and I found this silver '98 in a Denver self-service yard recently. The Catera had a lot going for it, with a rear-wheel-drive layout and a modern V6 engine that made more power than the BMW 528i's straight-six that year. It should have been able to compete with European luxury sedans in North America because it was a European luxury sedan. Unfortunately, you couldn't get a manual transmission in the Catera, "traditional" Cadillac shoppers thought the Catera lacked a sufficiently massive presence, and younger Cadillac buyers flocked straight to the Escalade starting in 1999. After 2001, the Catera was no more. I still find Cateras in junkyards, nearly 20 years after the last ones were sold, so they appear to have held together pretty well. This one was in nice shape until the end, with all the original manuals still in the glovebox. Even the Catera ballpoint pen remained with the car for its whole life. As we can see in the owner's manual, Cadillac marketed the Catera as "The Caddy That Zigs." The idea was that younger car shoppers would become as Cadillac-obsessed as their grandparents had been. Inspired by the ducks in the Cadillac logo, the Catera marketing team created Ziggy the Duck to pitch this car. Things didn't go so well. The Catera listed at $29,995 in 1998, about $47,600 in 2020 dollars. That made it an affordable alternative to the BMW 5-Series or Acura 3.2 TL, but total Catera sales came to fewer than 95,000 cars over five model years.
