GM is warning owners not to drive their vehicles until the repairs have been made.
The recall affects certain 2016-2017 model year Silverado 1500 and 2016 Sierra pickup trucks, along with several other GM SUVs, including the 2016 Cadillac Escalade, Cadillac Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon and GMC Yukon XLs.
The front upper control arms that help manage the motion of the wheels have poor quality welds] near the control arm’s bushing. They could separate and cause a collision.
“If the weld were to fail, steering and directional control of the vehicle could be compromised, which could increase the risk of a crash,” the National Highway Traffic Safety Administration said.
No crashes or injuries associated with this defect have been reported.
Mechanics will fix the issue by replacing the left and right front upper control arms and realign the vehicle as soon as the parts are available.
Dealers have already been notified of the issue. Owners will receive a recall letter this month, followed by a second notice when the parts are available.
