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:

GMC Safari GT, a rad-era hauler with custom-van swagger

The GMC Safari van, along with its Chevy Astro sibling, performed yeoman service ferrying passengers and hauling cargo for two decades starting in 1985. But one special variant, the Safari GT — and, at Chevrolet, the Astro RS — added an unexpected dollop of swagger. Those vans had a custom look that was straight out of the '70s "sin bin" era. One of those Safari GTs is up for grabs right now, fittingly, on the RADforsale auction site. The option package at both GMC and Chevrolet was coded BYP, the GT Sport Package, and it appears to have been offered from 1990 to 1994. Its defining element was the two-tone paint treatment shown here, with black on the lower body and the greenhouse, and your choice of white, silver, blue, gold, or red as the main body color. Blanked out rear quarter windows and "simulated air exhaust louvers" behind the middle side windows added a further bit of style (long-wheelbase XT versions skipped that flourish). Also included were a front air dam, blacked-out grille, aluminum rally wheels, and a sport suspension. This 1991 Safari GT appears to have been further sportified with a lower-body aero kit, a rooftop spoiler, and aftermarket wheels. This rear-wheel-drive, standard-wheelbase model is powered by a 4.3-liter V6 hooked to a four-speed automatic transmission. It has traveled a relatively low 126,000 miles and looks to be in exceptionally good shape — particularly given that most of these vans lived a hard life. At this writing, bidding stands at $5,100 with bidding to end May 21. That suggests this Astro GT will bring a strong price — but if you want one, you may be hard-pressed to find another.

New recall issued in 2019 Chevy Silverado and GMC Sierra brake software saga

General Motors (GM) has issued a new recall for select 2019 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks that aims to resolve a faulty fix for a previous recall. According to National Highway Traffic Safety Administration (NHTSA) campaign No. 20V055000, a software update for the Electronic Brake Control Module (EBCM) could cause the electronic brake assist to be disabled.  The NHTSA first launched a recall for 463,995 Silverados, Sierras, and Cadillac CT6es on December 12, 2019 due to a software issue in the electronic brake control module (EBCM) that could disable the electronic stability control (ESC) and anti-lock braking system (ABS). As a response and resolution to that recall, GM began to reprogram the software in affected vehicles. GM later learned that the fix was creating a different problem. The installed software had its own error that was disabling the electronic brake assist. If customers see “Service Brake Assist” or “Service ECS" diagnostic warnings, they should park the vehicle and have it towed to a dealership, GM warns. While GM was going through the process of testing, pinpointing the issue, determining action and working with the NHTSA, safety experts have criticized Chevrolet and GMC for not reacting promptly and appropriately.  According to the recall, 148,055 are now affected, all of which do not meet the standards of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems." To fix the braking issue, GM will once again reprogram the software. GM began notifying owners of the recall on February 10, 2020. Related Video:
