I am arriving to from Newark Airport on Sunday 12th May and will be collecting our rental car. I currently have a broken foot and will need a wheelchair when leaving the shuttle to collect car at Dollar- Will there be a wheelchair available?

I am not sure, but better to be prepared. As others mentioned people are helpful. No need to worry much. Be optimistic and upbeat. Have a safe and enjoyable journey.

Ask for assistance from the baggage claim to go rental car someone will assist you there in a wheelchair

Arriving in Newark at the help desk wheel chairs are available and to go to Dollar you can use the airtrain and the elevator so this should not be a problem. Maybe it's helpful to inform the airline about your needs. Have a save trip

Yes that rental car place have a person at the top of the ramp where the shutter stops and you just let that person knowe you need a assistem and they take you to the car desk and the car , they are tremendous good people ,
