2005 Kia Sorento Repair Question
Kia Sorento Rpm Problem
Speedometer readings would seldom match exactly with GPS as tire wear and inflation pressure etc would affect the actual reading and a variation of about 3 % is expected.
As to rpm not registering correctly and the speedometer suddenly going out of specs, it can mean a fault with the electrical circuit of the meter cluster. A connection could be loose or has poor continuity, high resistance in the ground circuit.
