My 2002 Santa Fe has about 40000 miles on it and I just started experiencing intermittent problems with my speedometer/odometer. It sometimes just drops to zero mph, no matter what speed I'm driving, what other electric components are on, or what outside temperature is. Hyundai service had no answers and, as you would expect, when I took it in for them to look at it, it worked. It has messed up several times since.
 
Any helpful suggestions?

Does a car of that recent vintage even have a speedometer cable though? Seems like most use sensors that feed electrical signals to the ECU.

possibly- not 100% sure how it works but if it is not a cable then it would still be easy enough to find the problem at the dealer - if it is a signal driven system - then you might have to look at where and when the malfunction occurs - possible electromagnetic interference from somewhere might be affecting the speedometer- i have an aftermarket setup that uses electrical signal and it used to malfunction going over a specific draw bridge for some reason... and have no problem anywhere else. is there any other malfunction? svc engine light? abs light? awd light? if your not there at the dealer they can always say they can't reproduce the problem but if your there and it presents itself - they should be able to figure out what is malfunctioning and why...

My speedo went on my 2001 Santa Fe twice. The first time it was the fuse, the second time it was an intermittent fault and was traced to a speed sensor. This was changed for about £130 by a main dealer.

The most common problem is a loose connection or moisture in the connection at the speed sensor on the transaxle. the next thing that I have seen is a worn speedo driven gear on the sensor itself. Provided the gear isn't when due to worn diff side bearings not a real complicated job or excessively costly. An experienced Hyundai tech would find the problem pretty quickly.

I bought a used 2003 Santa Fe with 59000 miles in December and I am having the same problem. Please let me know what the outcome is.

#8 of 42 Hundai Santa Fe Speedometer problem fixed! by dreber1

Thanks to all who submitted replies to my original speedometer problem. I took my Santa Fe back to the dealer and told them to keep it until they found and fixed the problem. It only took one day for them to see the problem. At first, they said it was the speedometer gear (in the speedometer) and they replaced it. When they took the vehicle out to test the "fix", the speedometer failed two more times. This time they replaced the sensor in the transaxle (which I and several of you suggested was the problem). That did the trick - it has worked ever since. Apparently they have an inherent problem with the early Santa Fe speed sensors, but for some reason, don't want to notify their customers to come in and have the sensors replaced. Thanks again.

#9 of 42 brake fault by stuart703

As I approach junctions etc and slow down, there is a grinding, clunking noise with the brakes. The brakes are also ineffective. If I remove my foot the sound will continue, but if i tap it sharply it will go away. It's quite dangerous. Has anyone any ideas?
