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.

91006142025-06-26. Service bulletin. ENGINE. ADJUSTER Valve Lash Customer's complaint may include a ticking noise coming from the engine. Technician's observations can refer to spongy or stuck hydraulic lash adjusters. Exhaust lash adjusters found with a "spongy" condition (compressible plunger) leading to the assumption of being defective/malfunctioning. EXHAUST lash adjusters are designed to be COMPRESSIBLE by hand. Intake lash adjusters found with a stiff or stuck condition (non-compressible plunger) leading to the assumption of being defective/malfunctioning. INTAKE lash adjusters are designed to be NON COMPRESSIBLE by hand. Do Not Replace EXHAUST lash adjusters when the following condition is present: should be compressible, but they will exert a reactionary spring force during compression and return to full expansion without a compression force. Do Not Replace INTAKE lash adjusters when the following condition is present: should feel very firm and difficult to compress. Once the correct functioning of the intake and exhaust lash adjusters is validated with the procedure above, refer to the Service Manual "HYDRAULIC LIFTER(S) NOISE DIAGNOSIS" procedure. After the corresponding service procedures from the Service Manual involving the Lash Adjusters have been conducted, refer to the detailed instructions in the Service Manual to diagnose and/or service any other component.

This bulletin involves cleaning the piston heads and cylinder head combustion chambers to resolve a spark knock condition being caused by oil intrusion through the PCV system."
90040032025-05-29. Service bulletin. STRUCTURE:BODY. Backlite Heated Liftgate Glass Assembly: For rear window defrost inoperative concerns where heated glass electrical tab has become detached, it is not necessary to replace the glass assembly. For loose or detached electrical tab, refer to TSB 23-007-25 for repair procedures on reattaching a loose tab. For burned or discolored gridlines on hard tops, DO NOT change the complete Flipper glass assembly. This discoloration is oxidation of the ceramic silver material and is normal. The Engineering standard call out the fact that this bus bar will change in color and is not a deterioration of the material or performance.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
