My Hyundai Elantra 2000 GLS Speedometer Gauge is Slipping!
The colder the weather the worst the slippage!
There is a loud grinding scraping noise when this happens.
Under 25mph - 30 mph it reads accurate.
Over 30mph - 40 mph it starts to slip more and more the faster I go.
45mph to 55 to 65 to 85 to 100 mph to even 110 mph when I'm doing less than 50 mph!
The speedometer reading is not inaccurate when the engine warms up but I'm afraid, because of the loud noise, it will wear out, not work and have to be replaced again!
The speedometer has been replace once already.
Any Ideas?
I had a car that did this to me. It started happening last year so I took it in and they were baffled. Lesson learned never take a car to a big chain store for a difficult diagnosis.They just told me to let my car warm up for 5 minutes and it would be fine. If I let it warm up it was good. This winter it started doing it again but it would do it all the time even after I let it warm up. I never bothered bringing it in again because it was dieing. If you are truly concerned take it into a mechanic ( a good one) and have them diagnose it. Your spedometer cable could just be wearing out.
I think that your elantra 2000 model doesn't have a speedometre snsr if so, you can remove your speed metre gear from your transmission and ckecked for damage if its ok you rotate the cable and let some one to check the response on gauge .some time the cable is damage from gauge side causing inapropriate fixation.

I went to my mechanic and he said it might help to grease the cable.
He also said since the mph races real high it's probably in the speedometer gauage area instead of at the transmission.
Once it warms up it works great!
