#11 of 23 05 GP GT: service traction/var eff steering/abs by tempala May 10, 2007 (2:04 pm)
My 2005 Grand Prix GT just turned 41000mi and now intermittently displays "service traction system/service variable effort steering/service ABS" (never says anything about basic brake system, no brake light ever comes on). Anyone experience this or have a clue what is going on? All 3 systems couldn't have gone bad simultaneously! I hope this isn't a bad computer module.

My 05 (which I just purchased last week) is doing the same thing. It will tell me every now and then to "Service ABS/Service Traction Control/Service Variable Effort Steering." My ABS Light comes on and the Traction Control Disabled light comes on.   Any ideas?

Replying to: jeremers (May 23, 2007 5:07 am) Just went and picked my 05 today with the exact same lights on. It was the right rear wheel bearing, and the right rear speed sensor. The lights were cleared and have not come back on as of today. It was still under 36,000 so not sure of the cost factor. Hope this helps!

Replying to: jeremers (May 23, 2007 5:07 am) Hm... I think I also have a same issue. On end of January, I bought 06 Grand Prix GT with 16,000 mi ( at that time it was great, my best car ever). I have nothing problem with it before the mechanic replaced the intermediate steering shaft. They said it was recall thing and of course it was under the warranty. After that, tapping and knuckling started through the steering ( actually the vibration also came up while braking). When I took in, the mechanic replaced wheel baring because it worn out ( this really did not make sence). the vibration was gone but the tapping remain. I had taken my GT 4 times for tapping issue. Last week, they finally fixed. What they have been done is re-adjusting steering intermediate shaft, and injected grease which is the newest version. The ABS service light still on, after replacing the wheel baring, However, it still needs to be fixed. Hpe it helps to anyone.   for me steering var, tapping was really anoying because I could feel while accelating and braking.
#15 of 23 Trac Light on Pontiac Grand Prix 2002 by cmichalak Jun 24, 2008 (7:43 am)
My trac light comes on after a couple miles and therefore my RPM's shut off. In one instance after the trac light came on my oil light came on and the car shut off! There is oil in the vehicle. I went to re-start it and it took 3 times of hard starting to get it started....HELP!

Replying to: morty72 (Apr 22, 2009 9:33 am) Most likely a bad wheel hub assembly which holds bearings and ABS speed sensor. Jack up the wheel off the ground. Grab it at 12 and 6 position and shake it. Any movement equals bad bearings. This will cause the wheel speed sensor to move around and be read as a faulty ABS/Traction Indicator. Then grab it at 3 and 9 and shake it, movement will most likely be worn outer tie rod ends. Same part for either side. Pontiac recommends using 3 new bolts for the hub to knuckle mounting. If asked about plastic or steel clip, they are talking about the clip that holds the ABS wire to the mount. NAPA part came with both. Jim
#20 of 23 Service Traction Control/ABS by cnancgo Jun 15, 2009 (7:53 pm)
I have a 2008 Grand Prix GXP and have had it in to the dealer 14 times in 11 months for the TC/ABS service lights coming on. I take a regular trip, approx. 1 hour 15 min, almost every weekend to the coast of OR. After the car has been driving between 45 min to 1 hour the service TC/ABS light comes on. It resets when the car is turned off and then it happens again on the way home. The dealer gets the same error message each time it is taken in. They have sent 2 specialists from out of town to look at the car and actually drove it the same route to see the error for themselves. They also hooked up a monitor so I could record the error when it happened. The computer says the car is at a dead stop when the TC/ABS light comes on, I was driving 65 miles an hour. Why can't they figure this out? Will the traction work when I am on ice? Is the car safe to drive? They have replaced sensors, wiring, etc. Anyone have any idea?
