The fifth-generation Cadillac Escalade got its big debut for the 2021 model year, introducing a long list of upgrades and changes compared to the preceding 2020 model year. Among these was a new independent rear suspension setup. However, some fifth-gen Cadillac Escalade owners may notice that their SUV’s suspension makes a pop or clunk sound when turning, but now, a possible cause for the issue has been identified, as has a fix.
According to a recent report from GM TechLink, some units of the 2021 through 2023 model-year Cadillac Escalade may emit a rattle, clunk, pop, or click sound from underneath the vehicle while turning. It’s possible that this sound can be duplicated when making a full left turn, followed by a full right turn, at slow speeds in a parking lot. The report indicates that the noise may sound like it’s coming from the front of the vehicle. However, the culprit could in fact be a loose rear sway bar link upper mounting.
To address the issue, a GM technician will inspect the rear of the Cadillac Escalade to ensure that the rear sway bar link upper mounting bolt and nut are properly torqued. If the rear sway bar link upper mounting bolt and nut are loose, the GM tech will torque the assembly to 74 pound-feet.
To note, a similar issue may be present for the current-generation Chevy Tahoe, Chevy Suburban, and GMC Yukon. All three of these vehicles, as well as the Cadillac Escalade, were overhauled for the 2021 model year, introducing a new independent rear suspension setup.
As a reminder, the fifth-generation Cadillac Escalade is available with two engine options, including the naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax engine. The GM T1 platform provides the underpinnings, while production takes place at the GM Arlington plant in Texas.
