: service power steering message



oxymoron
05-03-12, 11:01 AM
Searched about 10 pages and couldn't find a reference to this question.
This morning I got a message in the DIC to service power steering. It seemed to handle fine when the message was showing. I pulled into a parking lot and at full right hand lock, it did seem as if the assist was way down. Stopped car and after about 3 hours got back in. No sign of assist lost at full or partial steering lock.
Has anyone experienced this? Is it maybe a false message? Haven't taken it in to be looked at and didn't have time today to check fluid. When I arrived at my destination this morning, steering seemed normal, making me think a trip to the dealer would result in a "can not duplicate" scenario.

Any thoughts on this? Thanks

Hi oxymoron,

I'm sorry to see that you've been experiencing this! This message displays if a problem is detected with the speed variable assist steering system. If you notice that the effort required to steer the vehicle increases or feels heavier, I would recommend taking it to your dealership for a diagnosis (see "Steering "on page 8-5 of your owners manual for more details). Seeing as how the message has not been displayed again, however, I can appreciate your reticence to take it to the dealership and hope the community chimes in soon with helpful feedback!

Feel free to email me anytime at Katie_Lucille@gmexpert.com if you would like further assistance.

Best,

Katie

I had the same message pop up while cruising down the highway in drive at 65mph on my way to work this morning. As I pulled a gas station after exiting off the highway, I noticed my steering effort was way up. I park the car, gas it up, and when I'm leaving everything is back to normal and no message. I drive a few more miles to work and everything seems fine. I guess I'll just keep an eye on it and if it happens a few more times, I'll take it in.

Because my DIC messages were intermittent, I didn't think it was a fluid question. But that was it.
My fluid dipstick when car was at operating temp was barely wet. Had differential topped up a few months ago, too. Evidently things left the factory not topped up as I have read here often.

Mine has done it twice. Both times have been when I romped on it. I checked my fluid after the first time, and it was barely registering on the dipstick, so I topped it off. It happened again tonight, and the fluid level is perfect. Every time I shut it off and restart with no signs of the issue. Combine this with a noisy rearend at 4,700 miles, and I'm disappointed. Both will have to quit working before I hand it over to the dealer. It's my third CTS-V, and every time I keep thinking the previous problems were isolated. It's a great car when working properly, but I'm not too sure I'll buy one again. Lots of cars are making it through PDI with low fluid levels. Not that exciting after writing a check for my $70k car.

Well shit, I just took my brother in law for a drive in my 2012 sedan with 1004 miles on it and got the Service power steering and the steering got heavy. I pulled over and cycled the ignition and it stopped. I have about an ounce of patience with anything. This better not be a big problem or I am going to blow the hell up. a $73k car just rolling 1000 miles. And yes, it was in sport mode on tranny and suspension, but it failed while I was warming it up, I had not got on it hard yet. Automatic.

UPDATE: sure as hell, I just drove it again. Put car in sport tranny mode and suspension in sport mode. As soon as I gave it 75% throttle it triggered the Service Power Steering. I called onstar, and they ran a diagnosis and came up with nothing. Car is brand new with 1000 ish miles. I am wishing now I had bought a BMW, as I am nervous as hell about how careful the dealership will be with the car, considering the HORRIBLE experience I had with my 2008 Z06 at the local Chevy dealer.

Anyone Anyone?

I drove it for an hour this morning in both modes and all was well. It is a fourth car for me, so I am going to wait until a clear week rain free to take it in to the dealer.

Mine just did the same thing this morning. Has anybody figured out what this is? I dont want to have to pull my pulleys and tune so I can take it into the dealer. We all know if I bring it is with them on they are just going to point to the aftermarket stuff and say "THAT'S THE PROBLEM"

My 2012 sedan has done this about 10 times. It is drivable but more like manual steering. I particularly don't like it when this happens on the freeway. I've taken in twice but it wasn't giving the message in the DIC at the time and the dealer couldn't make it replicate. They ran the car and no code was thrown. The only thing they can suggest is to drive it right over if it happens again...... I would love to know the fix for this!

My car has done it 8 times now. Let me know if you figure out what it is. I topped off the fluid and that changed nothing it still does it.

#PIC5058B: Service Power Steering Message Possible DTC C0450 - (Mar 30, 2012)
Subject: Service Power Steering Message Possible DTC C0450



Models: 2008 - 2012 CTS Cadillac CTS All



--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
This PI was superseded to update recommended field along with model and model years. Please discard PIC5058A.
--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

A customer may comment on a "Service Steering System" message on the DIC int.

Recommendation/Instructions:

Upon further diagnostics the technician may find that he has a history C0450. Please verify that the DTC is not set because of the condition called out in the latest version of PIC5272.

If all diagnostics have not lead to a repair, please check G110 on the right side of the frame rail and repair as necessary. Dealer feedback has verified a possible loose G110.

Another possible cause for the C0450 may be the engine wire harness chafing on the right cylinder head or bracket (1). This condition could result in an increase to steering efforts but not total loss of assist. It would be noticed more in parking lot maneuvers. Please review picture below.





Inspect the engine wire harness for chafing along the right cylinder head. Repair the wiring as necessary using SI2000 Diagnostic Information and Procedures. Protect the harness from future chafing.

ADDITIONAL SI KEYWORDS:

EBCM EBTCM ground instrument IPC panel variable ves wiring

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

Has anyone had this problem fixed yet? I am assuming so. I am having the exact same thing now but almost every time I drive my 2008 STS and its only after a few minutes of driving does the DIC pop up and then the problem immediately exists. This just does not seem mechanical. However, more electrical or maybe a sensor but I will do more investigating on the wire harness to see if there is "Chaffing" anywhere present. Please let me know if I should be checking anything else besides this and fluid levels. This is becoming very agitating to drive like this and the dealer without a doubt will want to replace the Rack or the Pump or both and I want to make sure its not something else prior to going in that very painful, expensive direction. :want:

Thanks,
Jeff

Hi Jeff,

I can understand your concern with the problem your STS seems to be having. Although it looks like you are trying to get some advice from the forum before heading to a dealership, I just wanted to offer my assistance should you feel that you need it at any point in time. Hope you have a great day.
