| Anyone experiencing steering wheel vibration above 60 mph with the 2009 CTS? All attempts to fix the problem haven't worked. | |

i kept getting a vibrating feeling in my ears when i got over 40 mph. i have a 2009 cts,1000 miles on it. i thought i was nuts and when i mentioned it to my service writer,his reply was we know all about it. they ordered a rear differential insulation kit and re aligned the differential and now all its ok. i posted the following question earlier and have not had any response. when my car sits in the hot sun and i start it up the climate control blower only comes up to a little more then half speed. i have had climate control in cars since 1988 including a 2005 cts and when the car was hot inside the fan speed would come up to maximum, until the car started to cool down. the only way i can get the fan to come up on high speed is to lower the temp to 60 degrees or bring the speed up manually. general motors tech has told my dealer that this is the way it works in the 2008 and 2009 cts. i think they have a manufacturing defect. if any one else is experiencing this problem,please let me know. if it works properly,i would also appreciate hearing from you. joey245

I've got about 3200 miles on my CTS AWD with 3.6DI. Have always noticed a slight vibration in the steering wheel at highway speeds, it but wasn't that severe and thought maybe I was being overly critical. Mine has had the two recalls performed for onstar and airbag, a faulty window regulator replaced and door lock mechanism ordered because it would only sporadically unlock. It seems like every day there are new creaks and rattles but some only intermittent. The newest thing is a drivers seat backrest that creaks loudly when I move around. I'm an average sized and weight guy. Don't know why it would do that, but passengers even comment on it. I looked up the lemon law but no one repair has had to be made more then once, and the vehicle has not been out of service for the required time either. Quickly becoming disheartened with the purchase decision.

Replying to: asrose (Feb 18, 2009 7:57 pm) all this seems to be car unique......I have an 09 RWD non-DI model fully loaded otherwise...and have neither problem... picked it up in Sept 08 and have over 10K on it now without any problems...... here is the TSB for the insulators: This bulletin is being revised to update model years and add insulator washers (only for vehicles built without washers). Please discard Corporate Bulletin Number 08-07-30-044 (Section 04 - Driveline/Axle). Condition Some customers may comment on a drone, boom, moan or vibration during light acceleration which phases in and out in intensity. The condition may be most noticeable at about 80 km/h (50 mph), or 1000 - 1300 engine RPM, and occurs over a speed range of 5 to 8 km/h (3 to 5 mph). Cause This condition may be caused by the rear axle assembly responding to engine firing frequencies passed through the driveline when the torque converter clutch (TCC) is engaged. Correction For All Vehicles -- Calibration Update This condition can be verified by driving the vehicle to duplicate the concern and using the Tech 2® to turn off the TCC. If the noise stops when the TCC is turned off, the calibration detailed below should help to eliminate the noise or vibration. Important: • This calibration may result in decreased fuel economy up to approximately one mpg/kpg. Because of this, the software should not be used in a vehicle without this concern. • There are two calibration part numbers that are "selectable" for this controller. Read the description to determine the correct calibration for this condition. • DO NOT replace rear drive axle or propshaft for this concern. A revised calibration has been developed to correct this condition. Technicians are to reprogram the transmission control module (TCM) using SPS with the latest software available on TIS2WEB. Refer to the Service Programming System (SPS) procedures in SI. As always make sure your Tech 2® is updated with the latest software version. For Vehicles Built Prior to VIN Breakpoint 90159377 - Install Insulator Washers After Reprogramming 1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in SI. 2. Place a transmission jack stand under the rear differential assembly. 3. Remove the two front differential mounting bolts 4. Install the rubber insulators (2), GM P/N 20827776, between the rear drive axle and the body 5. Install the rear differential mounting bolt. Tighten Tighten the rear differential mounting bolt (1) to 220 N•m(162 lb ft). 6. Remove the transmission jack stand. 7. Remove the support and lower the vehicle. Parts Information Part Number Description Qty 20827776 INSULATOR ASM - DIFF CARR 2 Warranty Information For vehicles repaired under warranty, use: Labor Operation Description Labor Time K9532* Transmission Control Module Transmission Reprogramming with SPS 0.4 hr Add Install Rubber Insulators in Rear Differential 0.3 hr *This is a unique labor operation for bulletin use only. It will not be published in the Labor Time Guide. 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. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION © 2009 General Motors Corporation. All rights reserved. |
