2020-2025 Cadillac CT4 Steering Column Cover: A Guide to Fitment, Finish, and Replacement

Symptoms of a Failing Steering Column Cover

Since the steering column cover is a cosmetic trim piece, its failure will not affect the vehicle's drivability. However, a damaged cover can be a significant cosmetic issue or a source of constant noise. Symptoms are typically straightforward and easy to identify.

• Rattling or Squeaking Noises: This is the most common symptom. The noise is often most noticeable when driving over rough roads or turning the steering wheel. It is usually caused by broken mounting tabs or clips, which prevent the upper and lower halves of the cover from fitting together securely.
• Visible Damage: Scratches, scuffs, and gouges are common from daily use, such as from keys, watches, or during vehicle service. On models with a leather-wrapped finish, you might see peeling, discoloration, or worn stitching.
• Poor Fit or Gaps: A warped or damaged cover may not sit flush, creating unsightly gaps between the upper and lower pieces, or between the cover and the dashboard or steering wheel. This is often a sign that the part has been removed improperly in the past, breaking the delicate plastic clips.

Known Issues, TSBs, and Recalls

As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) issued by General Motors for problems directly related to the steering column cover on the 2020-2025 Cadillac CT4. While the CT4 has been subject to several recalls for other components like airbags, brakes, and lighting systems, the steering column shroud itself has not been identified as a problematic part by the manufacturer. Any issues with this part are typically due to wear and tear or accidental damage.

Variant and Trim Level Differences

This is the most critical information for anyone buying this part. While the basic plastic structure of the steering column cover is the same across all 2020-2025 Cadillac CT4 models, the finish is not.

• Standard Finish: Base and Luxury trims typically come with a standard molded black plastic cover.
• Upgraded Finish (Part No. 84751385): The upper cover with part number 84751385 is finished in black leather with orange accent stitching. This finish is specific to certain trim levels, such as the Sport and V-Series models, to match the rest of the interior trim.

Buying a Used Steering Column Cover

A used OEM steering column cover is an excellent way to save money, especially for a cosmetic part. Since aftermarket versions are generally not available, a recycled part is often the only alternative to an expensive new one. Here’s what to inspect:

1. Inspect All Mounting Points: This is the most important step. Carefully examine photos or the part in person. Look for broken or stressed plastic around the screw holes and, most importantly, check that all the small plastic snap-clips that hold the upper and lower halves together are present and intact. Even one broken clip can cause a persistent rattle.
2. Verify the Finish: Confirm whether you need the standard plastic finish or the upgraded leather with specific stitching. Ask the seller for clear, well-lit photos to check the color and condition of the stitching. For part number 84751385, ensure the orange stitching is not frayed or stained.
3. Check for Surface Damage: Look for deep scratches, gouges, or chemical stains that won't come out with a simple cleaning. On leather-wrapped versions, check for peeling, punctures, or excessive wear from the previous owner's keys or accessories.
4. Ask About the Donor Vehicle: Knowing the trim level of the donor vehicle can help confirm the finish. For example, a cover from a CT4 Sport is likely to be the leather-wrapped version.

Cost Comparison

Prices can vary based on condition and supplier, but here is a general cost breakdown:

Replacement Guide (DIY Difficulty: 1/5)

Replacing the steering column cover is a simple task that most DIYers can complete in under 30 minutes with basic tools. The estimated professional installation time is 0.5 hours.

Tools Needed:

• Torx driver set (often T15 or T20) or a small Phillips head screwdriver
• Plastic trim removal tool (recommended to avoid scratches)

Step-by-Step Process:

1. Adjust the Steering Wheel: Lower the steering column to its lowest and most extended position using the adjustment lever. This provides the most room to work.
2. Remove Lower Screws: Look underneath the steering column. You will find two or three recessed screws that hold the lower cover to the upper cover. Remove these screws. You may need to rotate the steering wheel 90 degrees left or right to gain access to the screw heads.
3. Separate the Lower Cover: Gently pull down on the lower cover. It is held in place by several plastic clips along the seam where it meets the upper cover. A plastic trim tool can help to carefully pry the seam apart without causing damage. The tilt/telescope lever will pass through a cutout in the cover.
4. Remove the Upper Cover: Once the lower cover is off, the upper cover can be lifted straight up. It is typically held in place by clips that attach it to the steering column assembly itself. Be gentle and wiggle it loose rather than pulling with force.
5. Installation: Installation is the reverse of removal. Position the new upper cover and press down until it clips into place. Fit the new lower cover, ensuring the adjustment lever is properly seated in its opening, and press it upwards to engage the clips with the upper cover. Finally, reinstall the screws from underneath. Do not overtighten the screws, as this can crack the plastic.
