exposure very inaccurate on EOS 10D?

I have an EOS 10D that frequently snap photos with one to two stop
over/under, judging by the histogram. This inaccuracy extends to the flash.
About half the photos are like this.

Now when I take photos with it, I have to check the histogram, adjust
exposure and flash exposure, then re-shoot the same shot.

It has been this way ever since I got it. After upgrading the firmware, it
is the same. Has anyone experienced this?

Also, with a 550EX attached, sometimes the flash goes into stroboscopic mode
for half a second when I'm previewing the photos on the camera.

In my experience, if my pictures are under or over exposed with the 10D,
it's my fault. Change your metering mode. Depending on the subject,
partial metering may work better than evaluative when the subject is
dark or backlit.

As for the flash, make sure your contacts are clean and you're not
bumping anything when previewing.

I've had no exposure problems...no problems of any kind with my 10D.
But then, I'm a highly trained (former) professional.

Don't try this at home!(?) ;-)

IME, such problems are usually down to user error. In particular, flash
exposure with E-TTL is actually quite non-trivial.

For non-flash stuff, I tend to use partial metering and meter for the
highlights 2-3 stops above the neutral meter reading (using RAW - don't go
for 3 stops with JPEG). This results in the desired exposure pretty much all
the time.

Watch exactly what you're metering off of, and the metering mode. I find
this is primarily user error. Not sure about the flash. If possible, try a
different 550EX and see if you can duplicate what's happening. That's never
happened on mine with either a 420EX or Sigma EF-500 Super.

Keep your back to the sun and always use manual exposure. That'll cure it.

This is a frequent occurance with Canon EOS products. I have heard
this particular complaint too many times, from too many different
Canon owners. Say what you will about Sigma SD* cameras, but exposure
is always dead on balls accurate. At one time, Canon actually was a
quality camera manufacturer. Once they got into the EOS line, things
started to "about face" for them. It's sad and pathetic what has
become of Canon.
