Service bulletin TT 27-15-01

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

Tech Tips (No Crank, No Start After Cold Soak issues): Concern may be the result of a leaking vacuum check valve not holding residual pressure overnight. This results in a hard brake pedal that may require more pressure than usual to allow the vehicle to crank.
