2020-2024 Cadillac XT6 Steering Column: Power Adjust Failure, Diagnosis & Replacement
This guide covers common failures, part numbers, and compatibility warnings for the power tilt and telescopic steering column in the 2020-2024 Cadillac XT6.
- The most common failure is the power tilt/telescopic adjustment, often due to a wiring or module fault, not the motor itself.
- Verify your vehicle has the POWER tilt/telescopic feature and does NOT have the 'Super Cruise' option before buying.
- A "Service Steering Wheel Lock" message that prevents the car from starting is a known issue related to the column's anti-theft system.
- The correct OEM part number for the complete assembly is 85561699, which can be found new for significantly less than MSRP from online dealers.
Symptoms of a Failing Steering Column
A problem with the steering column in the 2020-2024 Cadillac XT6 often presents as an electrical issue rather than a complete loss of steering control. Pay attention to these specific signs.
1. Power Tilt or Telescopic Adjustment Stops Working
This is one ofthe most common failures. You might find that the steering wheel no longer moves up, down, in, or out when you use the adjustment switch. The memory function that sets your wheel position may also fail. Forum posts from XT6 owners indicate this is frequently caused by a wiring issue, such as corroded connector pins or a damaged wiring harness, rather than a failed motor. In some cases, the issue may be the steering column control module itself.
2. "Service Steering Wheel Lock" Message and No-Start Condition
If you see a "Service Steering Wheel Lock" message on the dash and the vehicle won't start, it points to a communication problem. The Body Control Module (BCM) is not receiving the correct signal from the Steering Column Lock Module (K60). This anti-theft feature prevents the vehicle from starting if it can't confirm the steering column is securely locked. This can 🎬 Watch: Understanding the Service Steering Column Lock warning sometimes be triggered by putting force on the steering wheel after the vehicle is turned off.

If your cruise control, radio volume, or phone buttons on the steering wheel stop working, the problem is often the clock spring. The clock spring is a coiled ribbon of wires inside the steering column that allows the wheel to turn while maintaining electrical connections for the airbag and all the buttons. When it wears out or breaks, these functions are lost.
4. "Steering Assist Reduced" Warning
Some owners have reported a "Steering Assist Reduced" warning light, which results in noticeably heavier and more difficult steering, especially at low speeds. While this can be caused by the steering rack itself, it can also be triggered by faults within the column's electronic systems that communicate with the power steering control module.
Pro Tip: On some older Cadillac models, a common issue was the Torx bolts holding the telescopic mechanism backing out and falling, causing excessive play in the steering wheel. While not specifically confirmed for the XT6, if your wheel feels physically loose, it's worth inspecting under the dash for any fallen bolts before assuming a major component has failed.
Buying a Used 2020-2024 XT6 Steering Column
Purchasing a used OEM steering column can save you hundreds of dollars compared to a new part. Because these are complex electronic and mechanical assemblies, it's crucial to buy the right part and inspect it carefully.
Warning: This steering column is for models with the POWER TILT and TELESCOPIC adjustment feature. It will NOT fit base models with a manual adjusting column. Furthermore, this specific part is for vehicles WITHOUT the 'Super Cruise' hands-free driving option. Columns for Super Cruise vehicles have a different design to accommodate a light bar and other sensors. Always verify your vehicle's options before ordering.
What to Check Before You Buy
- Verify Part Numbers: The most reliable way to ensure compatibility is to match part numbers. The primary OEM part number for this assembly is 85561699. This number supersedes older part numbers, including 84625112.
- Inspect All Connectors: Look closely at all electrical connectors. They should be clean, with no bent, broken, or corroded pins. A damaged connector is a major red flag.
- Check for Physical Damage: Inspect the column for any signs of impact, cracks, or bends from the donor vehicle's accident. A bent column is unsafe and unusable.
- Confirm Included Components: Ensure the column comes with the tilt/telescopic motors and the control module if you are trying to solve an issue with those parts. Ask the seller to confirm what is included.
- Review Donor Vehicle Information: If possible, get the mileage from the donor vehicle. A column from a low-mileage vehicle is always preferable. Also, confirm the donor vehicle had the same features (power tilt, no Super Cruise).
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls from the NHTSA for the steering column assembly itself on the 2020-2024 Cadillac XT6. There are recalls for other items like rearview cameras and instrument panel lighting.
- TSB #24-NA-017: Addresses an issue where the heated steering wheel may be inoperative during a remote start.
- TSB #PIT5662G/F: Provides diagnostic information for trouble codes C056D or C056E, which can be related to the steering angle sensor 🎬 Watch: How to diagnose and repair trouble code C056D within the column.
Cost Comparison
Replacing the entire steering column is a significant expense, but buying a used OEM part offers substantial savings over a new unit from the dealer.
| Part Type | Estimated Cost |
|---|---|
| New OEM Assembly (Part #85561699) | $380 - $610 |
| New Aftermarket Assembly | Not commonly available |
| Used OEM Assembly | $150 - $400 (Varies by condition and seller) |
| Shop Labor for Replacement | $400 - $650 |
Frequently Asked Questions (FAQ)
How do I know if my XT6 has the power tilt/telescopic column?
Look for a small, four-way joystick or switch on the left side of the steering column. If you have this switch and can electronically adjust the wheel's position, you have the power feature. Base models without this feature have a mechanical lever to unlock and manually move the column. The power feature was standard on Premium Luxury and Sport trims.
Is programming required after installing a new steering column?
Yes, calibration is often necessary. The Steering Angle Sensor (SAS), which is part of the column assembly, will need to be calibrated using a diagnostic scan tool. If the Steering Column Lock Module is replaced, it may also need to be programmed to communicate with the Body Control Module.
Can I just replace the tilt motor or control module instead of the whole column?
Yes, in many cases, individual components like the tilt/telescopic control module (Part #84625122) can be replaced. This is a less expensive repair if you can accurately diagnose the specific failed component. However, the labor can still be significant as it requires disassembling the column covers.
What is the difference between the steering column and the steering rack?
The steering column is the part inside the cabin that you interact with, connecting the steering wheel to the firewall. The steering rack is located in the engine bay between the front wheels and does the work of turning them. A problem with the column is usually electrical or related to adjustment, while a problem with the rack often involves leaks or a complete loss of power steering assist. Replacing the rack is typically a more expensive job.
