GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

2021 GMC Terrain spied on GM's Proving Grounds

As the Chevrolet Equinox changes, so does the GMC Terrain. We saw shots of an updated Equinox not too long ago, and now our spy shooters have caught the GMC version of the crossover testing inside GM's Milford Proving Grounds. Similar to the Equinox, the Terrain is due for a mid-cycle refresh soon. Unfortunately, GM has this compact crossover covered up heavily to make sure we can't tell what's coming yet. The midsection of the vehicle remains the same as before, and we can even see the floating roof design outlined in the back by the camouflage. We imagine the majority of the changes will come up front with a new fascia including a different grille and headlight design. If it adopts the latest from the bigger Acadia, we'll be looking at a much more upright and butch-looking grille. That look descends from the full-size Sierra, though, so we'll see how much truck GMC wants to put in its small crossover. What will be most interesting of all is if GMC sticks to its guns with the wacky push-button shifter on the dash. The weird design has received mixed feedback, and this would be GMC's first big opportunity to respond. However, we expect most interior changes to be kept to a minimum, as this is only a mid-cycle refresh — GM completely redid everything for the full redesign in 2018. Additionally, we'll be interested to hear if the diesel will continue to be available as an option going forward. We'll likely see the refreshed Terrain sometime after the next Equinox is revealed. As it stands, this Terrain is probably a 2021 model year vehicle, and will be revealed at the tail end of this year, or in early 2020.

Chevrolet Silverado, GMC Sierra could get independent rear suspension

The Chevrolet Silverado and the GMC Sierra could reportedly receive a variant of the four-link independent rear suspension found under the new Tahoe and Suburban. While that's not a surprise, a recent report suggests electrification, not comfort, convinced General Motors to make the change. Replacing the time-tested solid rear axle with an independent suspension will improve comfort, handling and off-road prowess, while adding weight, and likely making the trucks a little bit more expensive. It's a fair trade-off, but GM Authority learned the real reason for the swap is that at least one of the pickups will spawn an electric model, and it's more difficult to package a bulky battery pack around a solid rear axle. The independent rear suspension takes up far less space, even if it has more moving parts. General Motors will build its first regular-production electric pickup on an evolution of the Silverado's T1 platform named BT1, according to the same source. The b stands for -- you guessed it -- batteries. The firm reportedly doesn't want to make two suspensions for cost reasons, so the independent setup will come standard regardless of whether the truck runs on gasoline, diesel, or electricity. As a bonus, Chevrolet and GMC could choose to offer their T1-based trucks with Magnetic Ride Control or an air suspension, options available on the 2021 Suburban and Tahoe. The independent rear suspension will also find its way to the next-generation GMC Yukon due to be revealed January 14, and to the 2021 Cadillac Escalade scheduled to make its debut February 4. The long-rumored, born-again Hummer will get it, too, because it will arrive as an electric model built on the BT1 platform. It's worth noting none of this is official, and General Motors has remained quiet about what's next for its new suspension design, and what will be under its electric truck's sheet metal. If the GM Authority report is accurate, the Silverado (pictured) and the Sierra could ditch their solid rear axle for the 2021 model year. The change will likely be accompanied by other tweaks inside and out. Featured Gallery 2019 Chevrolet Silverado 1500 View 16 Photos Chevrolet GMC Truck
