Lower Lateral Link detachmentOpen
The Office of Defects Investigation (ODI) has received 156 complaints alleging a suspension failure in model year (MY) 2018-2020 Model 3 and MY 2021-2023 Model Y vehicles. The suspension failure involves the detachment of the front lower lateral link, which potentially causes a loss of vehicle directional control. In most cases, there was no advance warning or indication that the suspension failure would occur. Â Some cases cite noises occurring prior to failure, but note that the vehicle provides no visual warnings. Once the failure occurs, the vehicle may not be drivable, thus requiring a tow. Tesla has previously recalled vehicles for lateral link detachments through two recalls. Recall 21V-835 addressed 2,791 MY2019-2021 Tesla Model 3 vehicles due to a production issue. Recall 23V-235 addressed 422 2018-2019 Tesla Model 3 vehicles that had experienced similar failures to those…
