My STS with Northstar engine started just dying while I was driving - no matter what speed or whenever, no rhyme or reason. It has pretty much stopped doing that, but now I have trouble starting it with anywhere from 2 to 60+ tries to get it started. Had AAA come over to haul it to a garage, and he started it by hooking on to the engine instead of the battery. It started and he said it most likely needed a new battery since that one was the original. Got a new battery, car started immediately then the next time I went to start it, it took about 30 tries. What is going on?

Diane -
What ever happened with your car? Did they find out what was the problem?? I have a 2001 STS that has been in twice for the very same reason. I could be doing 60 miles an hour on the Parkway and the car will completely turn off - no power steering, no brakes... or I could be idling at a light and it does the same thing. I heard some STS's were recalled because of this. HELP ! I don't want to get rearended becasue the car shuts off. Can Anyone advise me?

My STS spent more time at the dealership with electrical systems issues than in my garage. I had a lemon of a car. At 800 miles, a new engine was needed. Electrical systems issues haunted me the entire 18 months of ownership, before GM bought the car back.

I have a 1988 Cadillac Seville STS that I bought used with cooling fan problems.
The fan was grounded with a piece of wire to the battery.
The information center displayed,"Cooling Fan Fault."
I used the car as is.Then the "Gear selection fault" was also displayed.
After that,the digital display slowly started to flash on and off.
Now the instrument panel is mostly off.
In the morning's it's on for awhile and everything on the panel is working.
Then the display shuts off.
The car is still running as normal but I can't read any of the functions.
The self diagnostic shows the codes:
 
B120-B127-B441 current
E052 History
B552 History
 
It is very difficult to drive the car without seeing the instrument functions.
Please help me locate the source of the problem.

Yep.
 
You need to have the crankshaft postition sensor replaced.

#36 of 39 Brake light problem by lilczar

Jun 03, 2009 (7:24 pm)

Cadillac STS , one brake light on the drivers side doesnt operate when brake pedal is pressed. When the keyless entry is used the brake light works. There is no brake light fuse in box. Cant figure out how it can light up with the keyless entry, but not when using the actual brake itself...Any ideas???

My Bose system in the house blocked the signal When I deduce that I change the dip switch on the stereo. Now my wife can acess the car with her #1 but I can not with my remote #2, however the is sporadic. It occurs more often than not. Very connfusing and it doesn't matter with location
