I too am having the same issue with the "service traction control/ABS" lights coming on with the pulsing and shuddering, feeling like the ABS is kicking in when it shouldn't. I understand under some constraints that it should be looked at by a GM tech, but when the issue has no explanation to solve the problem except throwing money at it, well that just seems wrong. Especially having to pay for the diagnosis that there's no explanation. For the stalling issues, I will be cleaning the throttle body, as that seems to have worked for several people on this forum. With the braking issues, it seems to me that GM should take note of forums like this and address the problem and help it's customer. Negative publicity is not good for business. Christina, what is your email so I can get more information. Thanks

I'm wondering if you might be able to help me. I just had front and back brakes as well as the rotors replaced on my 2004 GTP. Unfortunately, we were in a hurry due to time retraints and I am wondering if the bf forgot something. After replacing them, now everytime I get in the car my ABS, Service Traction Control soon, Stability, and effortless steering (or something like that) lights all come on. After reading around I am thinking maybe there is a wheel sensor unplugged or knocked loose maybe that we didn't notice. The bf said he didn't unplug anything like that though. Oh and we also replaced all spark plugs and wires that day too (just in case that could mean something as well, something up front that could have got loose). My brakes work but the ABS don't seem to be or Traction Control. My steering seems fine though. I'd like to get some ideas to start with/look for and maybe any assistance in finding proper diagrams etc. I'm a girl LOL but am intersted in figuring this one out. I am guessing it has to be something not done right during the brake job because all of those lights weren't on before. Thanks for your assitance in advance!

I have been having the same issues! This is my 5th pontiac and never have i had this problem... My ABS ,Traction, Steering and brake lights have been coming on as soon as i start my car.. It started by when id first start it and start moving it sounds like a growling for a quick second then stops.. then began to start that noise when id be pulling in to park.. ive had it hooked to a diagnostic machine and at first it threw a few codes.. one being the main abs computer and sensors in the wheel hubs.. so the hubs was replaced.. started it and it threw an new code for my steering sensor..when i took it back the next day it wouldnt throw that code so we didnt replace that.. i then drove it directly to the GM dealer and they said that it was pointing to the abs module system which is i guess the heart of all this .. Guess its tied in together.. but then was told that they was only about 90% sure that this was the problem.. after being told i was gonna be paying .. could there be something that is being overlooked that would be the problem.. i hate to sink this into it and not be the problem..

I've made several posts here about this issue (for my 2004 Grand Prix). After having EVERYTHING replaced except the ABS computer control module it has become obvious that this is the problem. I have a friend who had same issue and that is what cured his, but the part is between $1000-1200 so I'm not investing in it. Just unplug the ABS control module and the growling and ABS kicking in when it shouldn't will stop. You won't have ABS but of course brakes work. The ABS/Traction Control & Brake warning on the digital display will ding and flash everytime you start it, but for me that was the only thing else I'm willing to do. I'm just waiting until January to ditch the car, which I love other than this issue which is frustrating. Don't look for GM to help you out. Many, many others have tried and they won't do a recall although it obviously needs to be.
#119 of 204 2004 GTP has three lights on. (ABS, Brake, Traction)
Jul 12, 2011 (5:14 am)
After gaining speed from 60 to 80 and BF jerking the car to the left real hard these three lights came on. One is service brake system, the other service abs system, and lastly service traction system. I don't know where to look. I had it hooked up to a computer to check and it gave me no code or anything. Could someone help besides GM ppl? Thank you!

Mike, hope you can help me with your experience. Just bought an 02 Gran Prix GT, the ABS and Traction Off light are constant on. Using a Genesis I've determined that both rear sensors are reading correctly but both front sensors read "2MPH" constantly rather I'm moving or not. Checked the front sensors at the wheel with a volt meter and both showed to be working when spinning the front wheels by hand. The right front has a history code and the left front has a history and current code. Tried to clear codes and the lights never go off, as soon as I turn the key back to the on position both lights come back on. I'm thinking short in the harness as you've described. I see that Dorman offers one for the right side but not for the left and that is where there is a current code. Will a damaged harness on the right cause codes on both sides? Do you know of a replacement for the left side or can I just cut and splice in new wire? Thanks in advance for your advice and help!

I found that both harnesses to the ABS sensors had deteriorated and broken about 4-6 inches from where they plug into the sensors. Fixed both sides and now the ABS and "TRAC OFF" lights don't stay on but instead they both blink together for the first several minutes while driving. There are several history codes stored but no current codes. History codes will not erase using a Genesis scanner????? So far I've noticed no shuddering or other unusual braking issues, just the #$% lights! Can anyone offer up some advice on what is causing them to flash? Should I try a used ABS module or ECM? Will I likely just get another module or ECM with the same issues? Any ideas would be greatly appreciated!

Update to my post. I posted about my BF taking off and jerking my car to the left then all these lights came on. ABS, brake, and traction control. I forgot to mention the steering wheel hardened. Well today we found out that the wiring harness was stripped and getting hit by the belt. We just retaped it and moved it away from the belt. All three lights came right off and my steering wheel loosened right up. Everything is back to normal....I guess if anyone is havong trouble with lights only should really check the wiring harness, make sure they're in good condition.
