Tried Auto ISO yesterday, never again.
That's a tough situation. Your car is in the shade so you might get some shutter speed variations if you are in matrix metering. It may read that your subject is dark, or it may read the background which is bright sun light. Honestly I think your scene is fooling your camera's meter. You should try moving you your car out of the shadow and try it again. That would be my guess. Or try shooting the car in Spot metering.

Mr web - the answer was given on page 2. Your guess is wrong.
In manual mode, if you have chosen a specific shutter speed and aperture, it should not change. So you are either not in manual mode or there is something wrong with your camera. If you are using spot metering then you can have widely varied exposure based upon the sampled spot, but again the variable should be the ISO not the shutter speed or the aperture which you have selected and should remain constant.
@ tdekany,
Which one is correct? I would like to know. Thanks.

The camera was bracketing
Since this is still going on I'll take a stab at it.
OP was shooting Tri-X but thought he was shooting Pan-X.
There is a reason the camera manufacturers give us a place to hold the end of the film box.
