Basically the shifter (bezel) is fine, the problem is the wiring harness that connects to the shifter.
The harness connector is not securely fastened to the shifter and so it works loose.
Also there may corrosions on the connector contacts.
The solution is to use a wiring harness with a clip that holds it on to the shifter, which requires a new shifter.
And, putting dielectric grease on the the connector contacts to prevent corrosion.
This is the shifter Post:
Gear Indicator LIghts All Lit Post #51 Post #62 has the TSB.
Stuck with Shifter Service after recall Post#19 has Flo100 instructions.
My repairs were done under Warranty.
Opening and closing the door corrects the problem until the next time.
It never affected the shifting operation.
When/if the connector actually falls off you will have a problem.
