GM cars and SUVs recalled for leaking transmission fluid

General Motors is recalling more than 194,000 vehicles from 2018 to 2020 due to transmission fluid leaks. The leaks stem from an auto stop-start component that may have been installed with loose or missing bolts. The leaking fluid can affect the transmission's performance, and if it leaks onto a hot exhaust component, could potentially cause a fire. GM says that to date, it knows of no accidents or injuries related to the defect. The issue affects models from all four GM divisions. From Chevrolet, the affected vehicles are: 2018 Malibu, 2018–2019 Cruze, 2018–2020 Equinox, 2018–2020 Traverse, 2019–2020 Blazer At Buick, the following models are included: 2018–2019 LaCrosse, 2019–2020 Encore, 2019–2020 Enclave, At GMC, the recall includes: 2018–2020 Terrain, 2019–2020 Acadia Cadillac has two affected vehicles: 2019–2020 XT4 and 2020 XT6 The recall is scheduled to begin in mid-December. Owners of the affected vehicles will be contacted. Dealers will inspect the transmission accumulator, and replace those with loose or missing bolts.

2024 GMC Sierra HD unveiled with new design and more powerful turbodiesel V8

The 2024 Chevrolet Silverado HD made its debut in September 2022, so it was only a matter of time before the GMC Sierra HD received a similar round of updates. Unveiled online, the truck gains a new-look design and a more powerful turbodiesel V8, among other changes. GMC developed the Sierra HD primarily for towing and hauling so the most significant changes are found under the hood. The available 6.6-liter turbodiesel Duramax V8 engine now develops 470 horsepower at 2,800 rpm and 975 pound-feet of torque at 1,600 rpm, figures that represent increases of 25 and 65, respectively, over the 2023 model and that match the 2024 Silverado HD's. GMC notes it increased low-end torque by about 25% by fitting a new turbocharger. The V8 spins the rear or the four wheels via a 10-speed automatic transmission.  On the gasoline side of the spectrum, the 6.6-liter V8's output stays flat at 401 horsepower and 464 pound-feet of torque. It's now bolted to a 10-speed automatic transmission, and replacing the 2023 truck's six-speed lets the engine run closer to its peak power for longer periods. Here again, rear-wheel-drive comes standard and a part-time four-wheel-drive system is available across the entire line-up. Properly equipped, the 2024 Sierra 2500 HD Crew Cab can tow up to 21,900 pounds. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), and the 3500 HD is capable of towing up to 36,000 pounds — that's nearly 13 Subaru BRZs. Buyers have a dizzying selection of trim levels and body styles to choose from. The range includes Regular, Extended, and Crew cabs as well as seven trim levels called Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate, respectively. The AT4X variant will not be available at launch, and the Denali Ultimate is new for the 2024 model year. Additionally, 3500 HD models can be ordered with dual rear wheels. What the truck looks like depends on the trim level. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic, respectively.

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:
