Service bulletin SA-027-19

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SA-025-252025-06-05. Service bulletin. Some vehicles may exhibit wiper blade contact with the A-pillar trim, with or without a chattering noise. This condition may be caused by worn or contaminated wiper blades. It can also be caused by bent wiper arms, or loose wiper arm retaining nuts due to improper handling. Improper handling occurs when pulling on or forcing the wiper arms. Technicians should be aware that while replacement of the wiper blade may resolve some cases, correction of bent components or repositioning of the wiper arms, particularly when the retaining nut is loose, requires additional steps to ensure proper alignment and function.
09-034-242024-07-04. Service bulletin. Some vehicles may exhibit the inner cloth (A) falling down at the rear end causing a poor appearance and obstructing the view of the back window.
