Welcome to iRV2

Unfortunately your issue is internal in the speedo head .
Needle binding on face plate or stepper motor internal problem.
Rebuilding or replacement required .

If there was a sensor or wiring issue , neither the cruise or odometer would function.

First off you have to verify what the chassis is sending to the spedo.....get a cheap scan tool and monitor vehicle speed (vss) if the signal matches your road speed then your issue is the speed head, if it does not then you have a chassis issue causing the speed to reads what it is being fed.

When I bought my 2000 HR 8 years ago, I had a similar issue. Speedo would read up to 35 and then stop. Get below 35 and it would drop. Salesman, who was a good friend of mine says "I guess you'll be driving with a GPS" ODO worked just fine.

I did a little searching and found a guy in Pennsylvania that rebuilds them. I wish I had saved his name and number for the number of times I've been asked about it.

He gave me two options. Take a picture of the ODO and send it to him, along with $235 and he would send me a rebuild, or send mine to him to rebuild. Checks only, no CC. He took my info and put one in the mail. I had it in my hand before the check even cleared the bank. Trusting guy. Sent the old one back as a core. Got a thank you call from him when he received the core.

Best business experience I've had in a long time.
