# Service bulletin 32\-025 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. - Type: Service bulletin - NHTSA id: 11010926 - Published by NHTSA: 2024\-12\-03 - Manufacturer's number: 32\-025 - Manufacturer's date: 2024\-11\-22 - Campaign id or software version: 32\-025 - NHTSA component: ENGINE ## NHTSA's summary Info Only Unnecessary starter replacements can result from customer complaints regarding engine starting issues. A new Starter Troubleshooting Guide has been created to provide a comprehensive list of starting system checks, which should reduce unnecessary starter replacements and associated warranty claims. Engine starting system warranty claims now require a completed Starter Checklist, a Battery Pack Midtronics Report, and a Cable Drop Midtronics Report. Claims filed without these documents may be denied. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2024/MC-11010926-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2024/MC-11010926-9999.pdf) The document is the manufacturer's.
