Hello!

Car in question:  1995 Volvo 850 w/ Turbo

A couple months ago I got my ignition switch replaced by a very
reputable shop.  They specialize in foreign cars and seem to very
knowledgable with Volvos.

Around 3 weeks after I had it replaced, my car, after it had been run
for awhile, refuse to start.  When you turn the key, it locks the
doors (not a standard occurence).  Once it set the alarm off.
Sometimes when this is happening, the brake pedal causes the dash
lights (check engine, brake, etc) to turn off when it is pressed.

The problem seems to happen at random times, but it does always seem
to be when the engine is warm.  I don't believe that it has ever
happened at the first start in the morning.

I am getting very frustrated with it.  The mechanic said that he
doesn't believe it could be anything that they caused when they put
the switch in, but it seems to be related since it never happened
before the switch was replaced (but it could just be coincidence).

Does anyone have any idea what it could possibly be?

Thanks,

A Troubled Volvo Owner
