2018-2020 Buick Regal Steering Column Cover: A Buyer's Guide to Fitment and Replacement
This guide covers the common failure points, replacement costs, and critical compatibility differences for the 2018-2020 Buick Regal steering column cover.
- The most critical factor when buying a replacement is matching it to your vehicle's manual or power tilt/telescoping column, as the cutouts are different.
- When buying a used cover, thoroughly inspect all plastic mounting tabs and screw holes for cracks, as this is the most common damage and leads to rattles.
- Replacement is a very easy DIY job, requiring only basic hand tools and about 20-30 minutes.
- Used OEM covers are the best value, offering a perfect factory fit and finish for significantly less than a new part, especially since aftermarket options are rare.
Symptoms of a Damaged Steering Column Cover
Failure of a steering column cover is almost always due to physical damage rather than mechanical wear. Here are the most common symptoms:
- Visible Cracks or Scuffs: The most obvious sign is physical damage. This can happen from impacts, attempted theft, or from being removed improperly during other repairs.
- Rattling or Buzzing Noises: If the plastic mounting tabs or screw holes break, the cover can become loose. This will often cause a persistent rattling or buzzing sound, especially when driving over rough roads. Some owners of this Regal generation have reported general plastic rattles from the steering column area.
- Interference with Controls: In rare cases, a broken piece of the cover could become lodged and interfere with the movement of the tilt/telescope adjustment lever or the ignition key.
Known Issues, Recalls, and TSBs
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA for the steering column cover on the 2018-2020 Buick Regal. The existing recalls for this vehicle pertain to the brake system and seat frames, which are unrelated to the column plastics. Any issues with the cover are typically isolated incidents of physical damage.
Compatibility Warning: The most significant issue when sourcing this part is the difference between vehicles with a manual tilt/telescoping column and those with a power tilt/telescoping column. The lower cover has a different cutout for the adjustment control. You must verify which system your vehicle has before ordering a replacement.
Buying a Used Steering Column Cover: What to Check
A used OEM cover is often an excellent choice, as aftermarket options are not widely available for this part. A recycled OEM part guarantees the correct color, texture, and fitment. Here’s what to inspect before you buy:
- Verify the Adjustment Type: This is the most critical check. Look at the donor vehicle's options or the part itself. A manual column has a large lever on the left side, while a power column has a small, four-way electronic switch. The cutout in the lower plastic shroud is different for each.
- Inspect All Mounting Points: Carefully check every screw hole and plastic clip tab. These are the most common points of failure. A cover with even one broken tab is likely to rattle or fit poorly. Ask the seller for close-up photos of these areas.
- Check for Cracks and Stress Marks: Look for hairline cracks, especially around the seams where the upper and lower halves meet. White stress marks in the plastic indicate it has been bent or stressed and may be prone to breaking.
- Assess Cosmetic Condition: Note any deep scratches, scuffs, or discoloration from sun exposure. While minor scuffs are normal for a used part, deep gouges are impossible to fix.
- Confirm Part Numbers: If possible, match the part number from your original cover to the replacement. Common part numbers for the upper cover include 39134101 and 13486176 (with head-up display), while the lower cover is often 13486243.
Replacement Overview and Difficulty
Replacing the steering column cover is a straightforward task suitable for a beginner DIYer. It requires basic tools and can typically be completed in under 30 minutes.
- Difficulty: 1 out of 5
- Estimated Time: 0.5 hours
- Tools Needed: Phillips or Torx screwdriver set, plastic trim removal tool (recommended).
Step-by-Step Guide:
- Adjust the steering column to its lowest and most extended position to create working space.
- Locate and remove the screws on the underside of the lower steering column cover. There are typically two or three.
- If your vehicle has a manual tilt lever, it can usually be pulled straight off its post with firm pressure.
- Carefully separate the lower cover from the upper cover. They are joined by plastic clips along the seam. A plastic trim tool can help release the clips without scratching the plastic.
- Maneuver the two halves around the turn signal and wiper stalks to remove them.
- Position the new covers and snap them together, ensuring all clips are engaged.
- Reinstall the screws on the bottom and push the tilt lever back into place.
Pro Tip: If you are chasing a rattle and the cover is not broken, you can apply small pieces of felt or foam tape to the contact points where the two halves meet. This can often silence minor vibrations from a slightly loose fit.

Frequently Asked Questions (FAQ)
How do I know if I have a manual or power tilt steering column?
Look on the left side of your steering column. A manual column will have a large, distinct lever that you pull to unlock and adjust the column. A power column will have a small, joystick-like switch that you press to make adjustments electronically.
Do I have to replace both the upper and lower covers at the same time?
Not necessarily. If only one half is damaged, you can replace it individually. However, they are sold as a set from most used parts suppliers, and replacing both ensures a perfect fit and color match.
Will a steering column cover from an Opel Insignia fit my Buick Regal? 🎬 Watch: Buick Regal and Opel Insignia steering wheel disassembly guide
While the 2018-2020 Buick Regal is based on the Opel Insignia, there can be minor differences in interior trim and options. It is always safest to source a part specifically listed for the Buick Regal to guarantee compatibility, especially concerning the cutouts for controls.
Can I repair a cracked steering column cover?
Small cracks can sometimes be repaired from the inside with a strong plastic epoxy, but the repair will likely be visible. Broken mounting tabs are very difficult to repair reliably, and replacement is almost always the better and longer-lasting solution.
