SSM 550932026-08-20. Service bulletin. Some 2021-2026 F-150 vehicles may exhibit a concern of the windshield wipers not parking in the correct position on the windshield and/or over-traveling.

Replacement of the wiper pivot arm, due to a missing alignment key is a not warrantable. Refer to Workshop Manual (WSM), Section 501-16.

These settings only need to be set once and will persist through subsequent remote starts. Heated and cooled seats will be set to Level 2 when turned ON via "Climate Settings" in the Ford mobile application during a remote start event. This is normal operating characteristic. This condition does not affect vehicle durability and no a
