- [SIB510922](/bulletins/10218415.md), 2022-08-22, Service bulletin: VISIBILITY; VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR; VISIBILITY:REARVIEW MIRRORS/DEVICES. A "squeaking" noise might be heard from the driver's exterior mirror when it's folding in and out. The gap \(4 \& 5\) between the base and cap of the exterior mirror is too small due to manufacturing oversight. This tight gap only applies to the driver's side mirror, because the passenger mirror was produced with different tooling.
