Filing in context
The Suspension Arm/Rod is the most frequently cited component category in this archive, appearing in 24 of its 4,890 filings. This filing is one of 46 Toyota notifications from 2023 in this archive. For scale, 65 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 3 years and 5 months.
Defect
The front suspension lower arm on affected vehicles contains cracks at the ball joint mounting area due to improper manufacturing of that section. Repeated driving over uneven road surfaces allows the cracks to propagate and, in the worst case, the lower arm may fracture, causing the ball joint to detach and resulting in loss of vehicle driving stability.
Corrective action
On all vehicles, inspect the left and right lower arms and replace any cracked lower arm with a conforming replacement part.
