Owners of 2021 Subaru Impreza cars should not drive their vehicles until dealerships can repair the front lower control arms.
More than 800 model year 2021 Subaru Impreza cars are being recalled because the left-front lower control arm weld may fail and allow the control arm to separate from the crossmember. Once this happens, the tire can make contact with the wheel well, causing a loss of control and an increased risk of a crash.
In June, Subaru received a field report about a vehicle with a partially separated control arm. The arm was collected, and Subaru opened a joint investigation with the supplier. In August, Subaru received a second field report for a similar issue. The LOT number on the control arms were the same. The same month, Subaru visited the supplier’s production facility.
The investigation found that the equipment on the control arm assembly line was damaged. The resulting contact between the part ejector rod and the welding torch made the torch unable to trace a proper welding path. As a result, some Subaru vehicles contain an improper weld.
Recall notices are expected to be mailed September 3. Subaru dealers will inspect the control arms, check the LOT numbers, and replace the arms, if necessary.
