Service bulletin FDM-TSB-004

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.

NHTSA's summary

This bulletin provides information and instructions for visually inspecting the LSTA piston accumulators to make sure the correct pressure accumulators were installed on the vehicle. A group of incorrect pressure accumulators were sent by the supplier and may have been installed on vehicles built between 8/1/2024 to 10/2/2024. A visual inspection of the accumulator label will determine if the correct accumulators were installed.
