My ABS and Check Engine and Traction control lights come on randomly
but
always together. I noticed that they come on at highway speeds above
70mph
every time as well. I have seen posts regarding similar problems and
was hoping someone would pass along their wisdom experience that led
to a solution.
If you had it diagnosed, what was the prognosis?

Thanks in advance.

It is all just a big fat guess until you have the computer read out and
determine the codes. Then we can make an educated guess.....

I have a 2000 Monte Carlo SS with 54,000 miles that is currently at the
dealer with similar problems. They have had it for a total of 7 days over
the last 2 months. It started with 3 warning lights coming on at different
times, but progressively got to the point last week where 5 warning lights
would come on for 5 seconds whenever the turn signal was used. Also, it
started having unpredictable starting problems. Previously, the diagnostic
test couldn't find a problem and the dealer said they couldn't do anything.
This time the diagnostics showed over 20 error messages. The dealer says
that their GM database says that replacing the ignition switch has solved
the problem on some occasions. I hope so since I just authorized the
repairs and am fed up with the problem and GM's crappy service and attitude.
