Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Can you get a scan for codes done on the vehicle please?
Sounds like a vehicle speed signal error, could be the sensor or wiring fault.
It may have P0500 VSS signal low input.
Hope this helps.
It depends on the amount of diagnosis time required to find the fault, plus the cost of any part required.
Could be the Vehicle speed sensor, at about $200 fitted.
Could be the instrument cluster, could be the engine computer, since the signal goes there first or a wiring fault.
Best to take your car to Hyundai to let me them fix it for you.
I hope my advice has been of assistance to you.
