GM recalls 51k Enclave, Traverse, Acadia crossovers over fuel gauge inaccuracy

With all eyes fixed on General Motors in the wake of the ignition recall debacle, the auto giant has been carefully calling in a wide array of vehicles to fix anything and everything that could prove problematic. Just the other day it issued two separate recalls - one concerning the Cadillac SRX and another its heavy-duty pickups - and now it is issuing another.
This time the vehicles in question are the Buick Enclave, Chevy Traverse and GMC Acadia, three fullsize crossovers based on GM's Lambda platform. In an estimated 51,640 units manufactured between March 26 and August 15, 2013, the engine control module has been found to incorrectly display the level of fuel in the tank.
As a result, owners are being notified to bring their vehicles in to their local dealers to have the ECU reflashed to fix the problem. View the full details in the announcement below from the National Highway Traffic Safety Administration.

2022 Chevy Tahoe, Suburban and GMC Yukon get updated transmission

General Motors' full-sized SUVs have slipped in one more change before the year turns. GM Authority reports that the 2022 Chevrolet Tahoe and Suburban, and the 2022 GMC Yukon and Yukon XL equipped with gas V8 engines, will pick up a revised ten-speed automatic transmission. The new unit carries RPO code MHS, and Chevrolet communications rep Catherine Scales told GMA the updated gearbox "allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future." It seems GM wants to make it easier to update the transmission's tuning and calibration in the future with the automaker's networked Vehicle Intelligence Platform/Global B electronic architecture. The 10-speed auto comes bolted to the 5.3-liter V8 and the 6.2-liter V8. The 3.0-liter inline-six Duramax diesel continues with the 10-speed automatic already in use. To recap the other changes for the full-sizers, we'll start with the 2022 Tahoe and Suburban, which get a new 12.3-inch digital instrument display to replace the former 8-inch unit and physical gauges. Navigation will be standard equipment displayed on the 10.2-inch infotainment touchscreen on all trims barring the base LS. Lane-keeping assist and parking sensors are also now standard, while reverse automatic braking is added to the Enhanced Display and Alert package on the top trims. Finally, the 6.2-liter V8 option is expanded to the Z71, RST and Premier trim levels, but it requires selecting one or more packages on the Z71 and RST. Moving onto the 2022 Yukon, availability of the 6.2-liter V8 expands to the AT4 trim, and the big V8 comes with a shiny pair of exhaust finishers. Redwood Metallic paint joins the exterior color palette, more wheel options are on offer, and illuminated sill plates can gussy up the rocker panels . An Enhanced Trailering Technology Package adds 13 cameras with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Inside, the Yukon welcomes the 12.3-inch digital cluster, the Yukon Denali welcomes the power sliding console as a standard feature instead of a $350 option.  Related Video:

GMC and AEV reveal Sierra Grande upfit SEMA concept

If there was any question as to whether GMC was dedicating resources to its off-road models, it was dismissed the instant American Expedition Vehicles entered the conversation. The two have already partnered to produce a GMC-branded alternative to the Chevrolet Colorado ZR2 Bison. The 2024 GMC Canyon AT4X AEV Edition is midsize pickup perfection, but the collaboration is far from over. With GMC now pushing the AT4X package on its heavy-duty pickups, AEV is looking for ways to explore the space.  "The Sierra Grande Concept represents AEV’s creative vision of how the company would further elevate the adventure-ready foundation of the GMC Sierra HD AT4X into a legendary overlanding rig," AEV said in its announcement The Sierra Grande is all Sierra HD AT4X underneath. The steering knuckles, control arms, rear suspension and butter-smooth DSSV dampers are all lifted directly from the production truck. This SEMA-bound concept is the quintessential upfit smorgasbord, boasting everything from add-on lighting to upgraded underbody protection. There are even two winches — one for the front and one for the back. If you ask us, they should have gone ahead and put one on each side too.  The snorkel pairs nicely with the 40-inch BF Goodrich tires, and the onboard air system guarantees you're never in a pickle when you hit pavement to head home. The bed is aluminum, but the skid plates are stamped steel (as is the brush guard). The front winch is rated for 12,500 pounds; the rear for "just" 9,500.  Unlike the Canyon AT4X AEV Edition, the Sierra Grande is merely an exercise — for now, anyway. We suspect that GMC has plenty more in store for its off-road trucks.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
