Service bulletin ITB14032

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.

ITB14028A2021-05-10. Service bulletin. SERVICE INFORMATION The information in this bulletin is provided to help ensure correct diagnosis and repair of fluid leaks. All fluid leaks, when properly diagnosed, should be repaired (whether under warranty or customer pay) to ensure proper vehicle operation. However, certain normal operating conditions can be misdiagnosed as a leak requiring repair. Unnecessary repair or replacement of parts in connection with incorrectly diagnosed "leaks" can negatively impact customer satisfaction, be time consuming and costly, and if not performed correctly can lead to future repairs. See this bulletin for further detail.
