Give me a museum and I'll fill it. (Picasso) Give me a forum ...
^^^^ Some dealers can be pretty shady.
Many years ago, our neighbor was a mechanic, and he told me how when he worked at a small used car dealer, one time a car came in that ran fine, but the oil light was on.
They cut the wire to the light.
A young teenager bought the car as his first car... A year later he came back saying the car was great !
Guess it was just the pressure switch.
Most cars go through a little initialization, where they light up every light on the dash. The intention (I assume) is so you can check for a burned out bulb. But there are so many now, that w/o a guide and time to look for each, the odds of noticing one missing, even if you tried, would be slim.
My 2017 Buick does a start up 'dance' of the speedometer and tach, running them from zero to full range and back down, I guess also to give some visual indication that they are working. Scared the cr@p out of me the first time, thinking for a split second that the engine was revving to max, and am I in gear? Took me a while to get used to that, it's still a bit unnerving.
