2017-2019 Karma Revero Door Panel: Fixing Blisters, Rattles, and Buying Used

Symptoms of a Failing Door Trim Panel

Failure of a door trim panel is typically related to its physical condition rather than mechanical breakdown. These issues can degrade the car's luxury feel and interior quietness.

• Rattling or Buzzing Noises: The most common symptom. This is usually caused by broken or loose plastic mounting clips on the back of the panel. The panel no longer sits securely against the metal door frame, causing it to vibrate with the vehicle, especially over rough roads or from the sound system's bass.
• Blistering or Peeling Material: On 2017-2018 Revero models, the material (often leather or a synthetic equivalent) can develop blisters or begin to separate from the panel's backing. This is a known issue addressed by a technical service bulletin.
• Poor Fitment or Gaps: If a panel has been removed previously without care, the mounting points or clips can be damaged, leading to visible gaps between the panel and the door frame or other interior pieces.
• Loose Switches or Controls: The panel provides the mounting structure for window switches, the interior door handle, and speakers. If the panel's mounting points for these components crack, the switches can feel loose or push into the door.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While no recalls target the interior trim panel itself, several official service actions are relevant to any owner or technician working on the doors of a Karma Revero.

TSB for Front Door Trim Panel Blister (2017-2018 Revero)

Karma issued Technical Service Bulletin TB-17-82-18 in September 2017 to address reports of the front door panel material developing a small blister. This issue affects 2017 and 2018 model year Revero vehicles. The official remedy involves carefully removing the door panel, heating the affected area with a heat gun to at least 400°F, and using a special roller to re-adhere the material. The bulletin also calls for replacing three specific screws and all nine door panel clips during reassembly.

Recall: Front Door Upper Intrusion Bar (2018 Revero)

NHTSA recall 19V408000 (Karma number RC-19-70-01) was issued for some 2018 Karma Revero vehicles because an internal structural bar in the front doors could be split, potentially reducing side-impact protection. The fix requires a technician to remove the interior door trim panel to inspect the intrusion bar. If you own a 2018 model, you should ensure this recall has been performed. This is also important for anyone buying a used door, as the panel may have been removed and reinstalled as part of this service.

No Known Issues for Karma GS-6 Panels

Currently, there are no widespread known issues, TSBs, or recalls specifically related to the door interior trim panels for the 2021-2022 Karma GS-6. Problems would likely be limited to general rattles from clips, which is common on any vehicle.

Buying a Used Door Interior Trim Panel

Due to the rarity of these vehicles, used OEM panels are the most practical and often only replacement option. Aftermarket manufacturers do not produce parts for such low-volume cars. Here’s what to check before you buy:

• Inspect the Backside First: This is the most important step. Flip the panel over and inspect all the plastic mounting clips. Look for any that are broken, bent, or missing. More importantly, check the mounting *points* on the panel itself where the clips attach. If the panel's plastic is cracked where a clip is supposed to go, the panel will not mount securely and will rattle.
• Check for Blisters or Peeling: Carefully examine the entire surface, especially on panels from 2017-2018 models, for any signs of blistering or material separation, as described in the TSB. Run your hand over the surface to feel for any bubbles.
• Verify the Trim Package: Confirm the panel is from a vehicle with the same interior trim (e.g., 'Palisades Sport'). Look at the color, the material of the armrest, and any wood or metal trim inserts. Get photos in good light to ensure it matches your existing interior.
• Examine Switch Cutouts: Check the areas where the window switch and door handle mount. Look for cracks or stress marks in the plastic, which could indicate a previous improper removal.
• Ask About its History: Ask the seller if the panel was removed for a specific reason, such as the intrusion bar recall. A panel removed carefully by a professional is a much better bet than one pried off with the wrong tools.

Replacement Overview

Replacing the door panel is a straightforward job for a DIY mechanic with the right tools, but requires patience to avoid damage.

• Difficulty: 2/5 (Requires care but not specialized skills)
• Estimated Time: 0.75 hours
• Tools Required: Plastic trim removal tools, Phillips screwdriver, small flathead screwdriver or pick tool. A 10mm socket may also be needed.

General Steps:

1. Remove Screws: Locate and remove all visible screws. These are typically found in the door pull handle/armrest area and sometimes behind small plastic covers near the door latch.
2. Pry Off Trim Covers: Use plastic trim tools to gently pry off any covers, such as the one behind the interior door handle or the master window switch panel.
3. Release the Clips: Starting from the bottom, slide a plastic trim removal tool between the panel and the metal door. Gently pry outwards to pop the first clip. Work your way around the perimeter of the door, releasing each clip. Do not pull from one corner, as this can break the panel.
4. Lift the Panel Up and Off: Once all side and bottom clips are free, the top of the panel is usually hung on the window sill. Lift the entire panel straight up to disengage it.
5. Disconnect Electronics: Don't pull the panel away yet. It will still be connected by wires for the switches, speakers, and lights, as well as the cable for the door latch. Carefully disconnect each electrical connector and the door latch cable before setting the panel aside.

Cost Comparison

Pricing for Karma parts can be difficult to obtain due to the low production volume.
