I have a small shop. I opened up the business so I can be one of the few mechanics that people can trust. I had two grand prixs come in today with the same exact problem. One was a 2004 other is 2005. The 04 I replaced the abs module as she told me she had already had all the speed sensors replaced. Same symptoms as yours. Did not fix it. No stored codes, and I tested the speed sensors while driving. Everything tested good. Even got the car to act up with the scanner hooked up and nothing. GM needs to do something about this. As far as the 05 I told her I would have to find out what the problem truly is before I waste her money. GM will not help all they say is you have to bring us the car to properly diagnose it. I am working on trying to find out the true cause of this and will post what I find so people can get their car fixed the first time and quit throwing money away.

OK folks, here is my update:
I contacted GM (Christina) via email and shared details, she informed me that there was no recall. I had also contacted the Pontiac Customer Assistance Center and opened a case. Christina became aware of this, and handed me off to an "agent". I spoke with my assigned "agent", who informed me that GM would likely assist with the repair, so he convinced me to take the car into the dealership for precise diagnosis and repair. I was encouraged by the conversation, and thought wow, the new GM really does care.
Although the hub bearings were previously identified to be making noise and thus in need of replacement, the secondary diagnosis upon further investigation was the simple ABS wiring harness was corroded all the way through. Upon replacing that part, the issue was solved. I requested the old part, which upon inspection, had water all through the inside of the harness casing. To me, that meant the design was flawed, and that added to my case.
Without going into the specific resolution, here is my advice for any of you who may be affected by issue you believe shouldn't be present. If your vehicle has low mileage or is otherwise just out of warranty, I would rate your chances of GM assistance to be good. If your car is older, maybe not so much. I will say that it took over 2 months to gain any satisfaction, but I did in fact get my repair issue addressed, and GM did in fact finally deliver on their earlier promise.
Bottom line: provided you have great patience (dealing with being handed off from agent to agent, not getting return phone calls, being over-committed to based on actual performance, etc.), and are willing to be actively engaged in seeing it through, and your situation aligns to the above details, it would behoove you to follow Christina's advice and contact them to discuss the matter. She stayed engaged from afar with my issue, and served as another point of contact, which I found to be of value.
Hope this helps, and thanks Christina (and GM) for your help.

Thank you for taking the time to share your experience and conclusion. You are very welcome, I am happy I could be of assistance. I would like to provide a little more information on why you may speak with a few different agents. There are different levels of Customer Assistance Representatives with different tools to assist customers. This is due to the wide variety of situations. I apologize as this can be frustrating; but this is why I wanted to stay in contact with you and make sure everything was taken care of for you. Anyone who would like to email me please feel free. I am happy to look into your situations, recalls, dealer concerns, and any feedback you would like to provide.

I have the same exact issue as above (#145), with my 2004 Grand Prix GT. I have the ABS activating at random braking times, for NO reason. The traction/ABS lights are lighting up like a Christmas tree. I changed the RH Half Shaft after investigating a very loud grinding noise. The RH boot had a hole in it and grease was everywhere. That ended up NOT being the noise issue, so I changed the LH as well. The grinding noise finally stopped after changing the LH, and so did the ABS acting up... briefly. About a month or so later, the ABS is acting up again, as described above.
Before spending a fortune on the dealer to tell me that it is not acting up when they drive it, I'm wondering if a relay has gone bad. Unfortunately, I'm not an electrician so my play is to start changing them and see if that works.
After being jumped on by my wife (she drives the car) I'm on the internet searching - and found this site. Please help me with a cheaper and quicker fix than going to a dealer.
Apparently I'm not the only one with this issue and I'm sure GM knows what the issue is. Please let me know how to fix it.

I've have the exact same problem with my 2007 Grand Prix GT. ABS and Traction control light come on. When i make a tight turn it seems like the ABS would kick on then off. Brought it to the dealer, at the time i had one of those Progressive Insurance driving monitors plugged into the computer. Dealership couldnt find anything wrong with my car, and told me to remove the monitor..i took it offbut it didnt change anything. My car stops just fine, so i havent brought it back in.

I have fixed the 4th grand prix today. Same problem abs kicks on usually at low speeds or while turning. Traction control light comes on but no codes. The Front speed sensor Harness has been the problem on all the grand prix. 2002 thru 2007. All of them have been on the left front. Good luck.

I am having the same issue. on my 2006 Grand Prix GXP left front Wheel sensor bad. ABS, Brake and Trac control lights are on. go off from time to time. had wheel hub replaced and didnt fix issue. dealer told me after they replaced it that it probably the cable now. So a flaw in the design of the cable from what I am seeing by reading this forum. Has a recall been issued on it yet? Anyone have any luck getting GM to replace when out of warranty? Can you please tell me the part number for the cable? Also direct me to any documentation on replacing the cable?

Can you please check to see if there are any open recalls on my vehicle? Also is there anyway you can help me in getting the left fron ABS wireing replaced on my vehicle? I had wheel hub replaced and still have the same issue.

I have had the issue for months now. I have brought my car the the dealership where they could not diagnose the problem but offer a repair suggestion of $1000 plus to fix so I brought to another repair shop that finally got a reading off my car and said it was my sensor so I replaced both sensors but the problem still exists. I am amazed to see so many people have the same issue as I do. The 8 of VIN number is 41264723 and my car has $71K miles on it. I woudlliek to know if htere are any recalls on my car.
