GM to recall nearly 4,800 big trucks and SUVs over suspension failures image

General Motors is forced to issue a recall campaign in the US for certain new full-size pickup and SUV models, as it found out some suspensions issues.

Following a routine test on a newly built GMC Yukon XL performed on April 5 at GM’s Arlington assembly plan, the engineers faced some serious steering and handling issues, for them to find out that the vehicle’s left front tire showed excessive camber and the left front upper control arm of the suspension was bend. Therefore, the arm was removed and sent to GM’s materials lab for further analysis which confirmed poor quality welding that may cause the arms to deform or break even at low speeds.

After GM concluded the full investigation on the matter, it decided to issue a recall of 4,789 vehicles in the United States, affecting certain model year 2016-2017 Chevrolet Silverado 1500 and 2016 Cadillac Escalade, Cadillac Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, GMC Yukon and GMC Yukon XL models.

The company will notify owners and dealers will replace the left and right front upper control arms and realign the wheels. Vehicles produced on or after April 8 are not affected by the failures, as they were built with parts of supplier improved manufacturing processes, GM said.

Customers will be mailed an interim notification in early May and will be sent a second one when remedy parts are available. Until the repairs have been made, the automaker advises owners not to drive their cars.
