I have the same problem - last yr it came on during vacation in hot weather and a lot of stuff in and around the seats. It came off at the Honda dealer parking lot in October (at least that's what they told me). It came on again this vacation - I'm waiting for the cool weather to set in again. I have taken out all of the stuff from behind the driver's and passenger's seat hoping this will have some effect. Good Luck.
Could be your speed sensor on your transmission
Anything that brings the car to a complete stop? Such as the brakes or a Tree?
You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
My 89Chevrolet astro van digital speedometer stop working. How do I fix it
why would a speedometer stop working on a Mazda
you can go to speedometer and out of speedometer
Most likely the VSS. Vehicle Speed Sensor. It is mounted on the side of the transmission.
Sounds like the speedometer cable broke.
spray pam on them
A blown fuse can cause your fuel gauge and speedometer to stop working. Replace the fuse. The fuse can be found in the fuse box. The location of the fuse will be listed on the inside cover of the fuse box.
Broken speedometer cable.
