2000 hyundai Elantra speedometer making noise and reading wrong

I was on the highway and suddenly the speedometer went over 100 mph and dropped straight down, I was going about 60 at the time. Then, it started making a loud noise. I pulled over and at a dead stop it was reading 20 mph, I started going again, the noise had stopped and speedometer was moving as it would normally except at 20 mph more than I was actually going. Once again, it did the same thing, dropped straight down and making noise. What would cause this? Is it expensive to repair? Is it something I could do myself? Appreciate any help - Frustrated Lady

    So, I apparently need to add more details. The sound it makes when the speedometer spins to the right and then goes straight down, sounds like a motor or like when you clip a playing card on a bike to make the sound only louder. Once I pull over it stops. But it appears to do it again once I reach 40 mph. I hope this helps. It's still doing it and I am using a friends car because I've called a few shops, I don't know anyone trust worthy or a good shop. The shops I've called had different answers and sounded like it would be a thousand and up and if I take it, and they get it apart to look at it, they will charge me twice if they put it back together and I don't do the actual work. It's made me nervous to do anything. Borrowing a friends extra car for the moment.

My speedometer odometer;cruise recently stopped working 2000 Hyundai elantra I don't know where to start looking?

First thing I would go after is the speed sensor on the transmission. Have the codes read to make sure. The sensor is on the drivers side. Standing at the fender, look down between the air plenum/filter and the engine and you will see it.

A repair shop can
No way to guess at what you have or haven't
done, as far a preventative maintenance goes
I will say this,IF you just drive any car & never go
to a shop or educate yourself or spend time at a shop
& ask the right questions, then you will have issues
To notice a mileage drop you have to have things that
either need attention or you have an unfixable mechanical

My 2000 Hyundai Elantra is stalling intermintantly as I slow down at stop signs/lights, etc. I have noticed that the speedometer is not working properly.....i.e. when I'm moving at 30 mph the speedo is...

According to the Hyundai service website, "If there is an open or short circuit in the vehicle speed sensor signal circuit, the engine may stall when the vehicle is decelerated to a stop." This sounds like what you're describing, so you should check out the detailed troubleshooting info for the VSS at, available free with registration.

The transmission does have a separate computer (TCM), it's a $700 plus item from the dealer, but if necessary you can get one for much less from a salvage yard. The same goes for the ECM.

"Humming" or "bearing" type noise in left front at highway speeds

That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.

Speedometer Gauge Slipping - Inaccurate Reading

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.

2000 Hyundai Elantra Transmission problem

I don't know if I can help but as an owner of a Hyundai Elantra 2000 GLS with 205,000 miles and the original clutch and transmission I'll try and help!

I always start with the lowest cost solution first and avoid mechanics as much as possible!

Have you checked the trans fluid?
It should be changed every 30,000 miles!
Sometimes a Lucas Trans Fluid will cure - fix slippage!

Have you checked for a clutch adjustmet!
An adjustment can cure - fix slippage!

Are you a clutch rider with your foot always on the clutch?
If so you may have worn out the clutch!

How many miles to you have on your Hyundai Elantra 2000?
