2017-2019 Karma Revero Steering Column Cover: Fixing Rattles and Damage

Symptoms of a Failing Steering Column Cover

Failure of a steering column cover is almost always physical or cosmetic. Because it is a simple plastic trim piece, it will not trigger any warning lights or diagnostic trouble codes. Symptoms are typically seen or heard.

1. Rattling, Buzzing, or Creaking Noises

This is the most common symptom of a failing steering column cover. The noises are often most noticeable when driving over rough roads or when turning the steering wheel. These sounds are typically caused by:

• Broken Mounting Tabs: The upper and lower halves of the cover are secured by plastic clips and tabs. Over time, this plastic can become brittle and break, preventing the cover from fitting together tightly.
• Loose Screws: The screws holding the lower cover in place can sometimes back out, allowing for excessive movement and vibration.
• Improper Installation: If the cover has been removed previously for other repairs (like ignition switch or turn signal stalk replacement), it may not have been re-seated correctly, leading to a poor fit and rattles.

2. Visible Cracks or Physical Damage

The cover can be damaged from impact, such as from a knee or from items being stored in the driver's footwell. Look for cracks, deep scratches, or stress marks (white lines in the plastic), especially around the screw holes and seams. A cracked cover can be a source of future rattles and may have sharp edges.

3. Loose Fit or Gaps

You may notice the cover feels loose to the touch or that there are uneven gaps where the two halves meet. This indicates broken internal clips or that the cover is not properly seated, which can allow dust and debris to enter the steering column assembly.

Buying a Used Steering Column Cover

Due to the low production volume of the Karma Revero, new aftermarket covers are not manufactured. A used OEM part is the most practical and cost-effective replacement. When purchasing a used cover, a thorough inspection is critical to ensure you get a good, usable part.

What to Inspect:

• Mounting Points are Key: This is the most important check. Carefully inspect all screw bosses (the plastic towers the screws go into) and all plastic tabs and clip receivers along the seams. These are the most common failure points. If a screw boss is cracked or a tab is broken, the cover will not install securely and will likely rattle.
• Check for Cracks and Stress Marks: Examine the entire surface of both the upper and lower pieces, especially in corners and around openings for levers. Bend the plastic slightly to reveal any hidden stress marks, which look like faint white lines and indicate the plastic is weak and close to breaking.
• Surface Condition: Look for deep scratches, scuffs, or discoloration from sun exposure. While minor cosmetic issues are expected with a used part, significant wear may not match the rest of your vehicle's interior.
• Confirm Both Halves: Ensure the listing includes both the upper and lower halves of the cover, as they are a matched set.

Known Issues, TSBs, and Recalls

There are no specific recalls or Technical Service Bulletins (TSBs) for the steering column cover itself. However, technicians and DIYers should be aware of related issues in this area of the vehicle:

• Steering Column Knocking Noise (TSB TB-18-44-01): Some 2017-2018 Reveros may develop a knocking noise from the steering column when the wheel is pushed or pulled. This is caused by loose telescope actuator bolts and is not a failure of the cover.
• Airbag Recalls: The 2018 Revero was subject to recalls related to the airbag system, including one for rollover sensors that were not enabled (NHTSA Campaign 19V296000). Since the driver's airbag and its wiring are housed within the steering column, extreme care must be taken when working in this area. Disconnecting the battery is a mandatory safety step.

Replacement Overview

Replacing the steering column cover is a relatively simple task that most DIYers can accomplish with basic tools. The main challenge is being careful not to break the plastic tabs on the new or existing cover.

1. Safety First: Disconnect the negative terminal of the 12V battery to disable the airbag system.
2. Adjust Steering Wheel: Use the tilt and telescope feature to lower the steering wheel and extend it as far out as possible. This provides the best access.
3. Remove Screws: Locate and remove the screws on the underside of the lower cover. There are typically two or three Phillips or Torx head screws.
4. Separate Halves: Gently pry the upper and lower halves apart at the seam. They are held together by plastic clips. A plastic trim removal tool can help avoid scratching the surface. You may need to turn the steering wheel 90 degrees left or right to get better access to release certain clips.
5. Remove Levers (If Necessary): On some designs, you may need to remove the tilt adjustment lever, which usually pulls straight out.
6. Installation: Installation is the reverse of removal. Carefully align the two halves, ensuring all clips are engaged before pressing them together. Reinstall the screws without over-tightening them to avoid cracking the plastic. Reconnect the battery when finished.

Cost of Replacement

Pricing for Karma Revero parts can be difficult to pin down due to the vehicle's rarity. Aftermarket options are nonexistent.
