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.

Cadillac XT5, XT6, GMC Acadia recalled for two issues

General Motors is recalling three model years of the Cadillac XT5 and XT6, and the Cadillac's GMC sibling, the Acadia. The first recall has to do with the rearview camera. On 2020- and 2021-model-year XT5s, XT6s, and Acadias optioned with Surround Vision, insufficient crimping for the coaxial cables could cause a degraded signal from the rear camera, or cause the signal to fail. With all passenger vehicles required to have a working rearview camera, that's not an ideal situation. Only crossovers with Surround Vision are affected. The population at issue counts 95,231 vehicles, build dates being: XT5s produced from May 1, 2019 to June 23, 2021 XT6s built from February 25, 2019 to June 24, 2021 Acadias built from May 6, 2019 to June 24, 2021  The automaker hasn't been informed of any crashes or injuries related to the problem, and will begin mailing letters notifying owners of the issue on November 7. The fix is a trip to the dealer to have the cables inspected and replaced if necessary. Concerned customers can contact Cadillac customer service at 800-458-8006 or GMC customer service at 1-800-462-8782, then refer to GM's recall number, N222378380. Alternatively, they can get in touch with the National Highway Traffic Safety Administration (NHTSA) Safety Hotline at 888-327-4236 (TTY 800-424-9153), or go to www.nhtsa.gov, and refer to campaign number 22V709000. Another recall concerns just the 2023 Cadillac XT5 and XT6 and 2023 GMC Acadia units that were built on August 9, 2022. That day, a printer in the Spring Hill, Tennessee, Assembly Plant malfunctioned, producing vehicle labels for the driver's side B-pillar with illegible tire size information. That's a violation of a subsection of Federal Motor Vehicle Safety Standard No. 110. Only 24 units are affected, the fix being a jaunt to the dealer for a label with readable information. Owners who don't want to wait until November for letters from GM can contact Cadillac customer service at 800-458-8006 or GMC customer service at 800-462-8782, and mention recall number N222381690. Or they can head to the NHTSA Safety Hotline at 888-327-4236 (TTY 800-424-9153), or www.nhtsa.gov, and refer to campaign number 22V708000.

GM recall woes continue with 662,000 pickups trucks and Cruze sedans

General Motors can't seem to get its name out of the "bad news" column. Two more recalls were announced late Friday evening that will see The General calling in 490,200 fullsize pickup trucks and SUVs, along with 172,000 Chevrolet Cruze models.
For those keeping track, General Motors has issued recalls for an alarming 4.8 million vehicles so far since last month.
The Chevy Silverado 1500, Tahoe and Suburban, GMC Sierra 1500 and Yukon models from the 2014 and 2015 model years are being recalled for a flaw in their transmissions wherein loose oil cooler lines may cause a fire. The automaker said in a statement (see below) that it knows of three incidents of loose transmission lines causing problems, but no injuries. We can't confirm whether it was this transmission issue that caused the widely publicized blaze that consumed a 2015 GMC Yukon that was being test driven in California.
