I was driving my S60 and about a mile down the road
the transmission felt like it slammed into gear. It was
not changing gears at the time. It felt similar to when
I had computer issues before that were fixed by a
software upgrade.

It happened one more time another mile down the
road and then the brake and ABS lights come on. The
mssg window says "Brake system failure stop when
safe" or something similar. Then all the gauges shut
down, I couldn't roll down my window and my air got
hot. I came to a stop and shut the car off.

I pulled out my OBD reader and it gave me p0116
and U0100 p. I then cut the car back on and the
guages came back on, the windows would work again
but the temp guage was maxed and the mssg
window said "high engine temp" and "SRS Airbag
Urgent service".

The over flow had fluid and the vehicle did not feel
that hot. I squeezed the hoses and there was not that
much pressure. I left the car for an hour and the
guage still showed it as maxed out.

Am I dealing with some massive computer failure or
is there any way all these different problems and
messages are happening?
