speedometer dies at times
On my 08 Vette the speedometer needle will start to bounce around wildly then settle at zero. A short time later it begins to bounce around again and goes back to normal. If the radio is on the sound drops off at the same time. Sometimes the dash displays service traction control. When the speedometer starts working again the traction control display also clears. On one occasion the check engine lite came on. The code was p0502 Vehicle Speed Sensor (VSS) Circuit Low Voltage ECM.
I've been waiting for complete failure before taking it in for service, but it
just continues to come and go. Anyone have any ideas? The car does nor have the telescopic steering wheel.

The cluster might fall under one of the longer warranties provided with the car. Check with a dealer. Dad got his 2004 truck speedo fixed about 4 years ago with almost 100k miles on the truck.

The sensor needs cleaning or replacing. Since the volume of the radio increase and decreases with speed (if you have auto leveling) that why the radio is involved. The sensor is located on the top off the rear differential.
