2017-2020 Karma Revero Radiator Splash Shield: A Guide to the GM-Powertrain Undertray
This guide covers the specific radiator support splash shield for the 2017-2020 Karma Revero, focusing on the critical compatibility differences and what to inspect on a used part.
- This shield ONLY fits 2017-2020 Revero models with the GM engine; it will NOT fit the 2020+ Revero GT or GS-6 with the BMW engine.
- Failure is caused by physical damage and results in scraping or flapping noises. It does not cause check engine lights.
- New aftermarket parts are not available, making a quality used OEM part the best value for replacement.
- Driving without the shield exposes critical engine and electrical components to damage from water and debris.
Critical Compatibility Warning: GM vs. BMW Powertrains
Warning: This radiator support splash shield (OEM Part Number C171000000298) is specifically for the 2017-2020 Karma Revero equipped with the original GM-sourced 2.0L turbocharged engine-generator. Starting in mid-2020, Karma introduced the Revero GT, followed by the GS-6 in 2021. These newer models use a completely different 1.5L BMW-sourced powertrain and have revised bodywork and subframes. The splash shield from a Revero GT or GS-6 will NOT fit the earlier GM-powered models, and vice-versa. Always verify the model year and powertrain before purchasing.
Symptoms of a Damaged or Missing Splash Shield
Failure of this part is almost always due to physical damage from road hazards like curbs, speed bumps, or debris. The symptoms are physical and audible, and will not trigger any check engine lights or diagnostic trouble codes.
- Scraping or Dragging Noises: The most common symptom is a scraping sound, especially when driving over bumps, dips, or up steep driveways. This indicates the shield is loose, sagging, or has a piece dragging on the pavement.
- Flapping or Rattling at Speed: If fasteners are missing or broken, the shield can flap in the wind at highway speeds, creating a loud rattling or drumming noise from under the car.
- Visible Damage: A visual inspection may reveal cracks, holes, large missing sections, or that the entire shield is gone. Pay close attention after hitting any object on the road.
- Excessive Dirt and Moisture in Engine Bay: If you notice an unusual amount of dirt, mud, or water spray on the engine and other components, it's a strong sign the shield is no longer providing protection.
Buying a Used Radiator Support Splash Shield
Due to the rarity of the Karma Revero, new aftermarket splash shields are generally not available. A new OEM shield can be very expensive, making a quality used OEM part the most practical and cost-effective solution. When inspecting a used shield, focus on these key areas:
- Check All Mounting Points: The holes where bolts and clips attach are the weakest areas. Ensure they are not cracked, torn, or elongated. A shield with damaged mounting points will not attach securely and will likely fail again.
- Inspect for Cracks and Tears: Look for major cracks, especially ones that run from an edge toward the center. While minor scuffs and scrapes are normal, large cracks compromise the structural integrity of the panel.
- Look for Heat Damage or Warping: Check for any signs of melting or warping, particularly around areas that would be close to the exhaust system. This could indicate the car it came from had other issues.
- Verify the Part Number: If possible, confirm the OEM part number is C171000000298. While there may be other numbers on the part, this is the primary identifier for the main assembly.
Pro Tip: A used OEM shield, even with minor cosmetic scrapes, is often superior to a new aftermarket part if one were available. The OEM part is designed for a perfect fit, which is essential for proper aerodynamics and cooling, and is made from materials specified by the manufacturer for durability.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls, Technical Service Bulletins (TSBs), or common failure patterns issued by Karma Automotive or the NHTSA for the radiator support splash shield on the 2017-2020 Revero. Failures are exclusively related to external physical damage.
The vehicle has been subject to other recalls for issues such as faulty airbag rollover sensors and intermittent turn signals, but none involve the underbody panels.
Cost Comparison
Prices for this part can vary significantly given the low-volume nature of the vehicle. The lack of aftermarket options makes used OEM parts particularly valuable.
| Part Source | Estimated Cost |
|---|---|
| New OEM | $450 - $700+ |
| New Aftermarket | Not Available |
| Used OEM | $200 - $400 |
| Shop Labor | $120 - $250 |
Cost estimates are for the part only, except for labor. Labor costs are based on a typical shop rate of $120-$200/hour for 1-1.5 hours of work.
Installation Details
- Difficulty: 1/5 (Easy)
- Estimated Time: 0.5 - 1.5 hours
- Tools Required: Basic hand tools (socket set, screwdrivers), potentially a trim clip removal tool.
Replacement is straightforward. The vehicle needs to be safely raised on ramps or jack stands. The shield is held in place by a series of bolts and plastic push-clips. Simply remove all fasteners, lower the old shield, and install the new one. It is common for the plastic clips to break during removal, so it's wise to have a few replacements on hand.
Frequently Asked Questions (FAQ)
Can I drive my Karma Revero without the radiator splash shield?
You can drive the car for a short time in dry conditions, but it is not recommended. Driving without the shield exposes the engine, radiator, and critical electrical components to damage from water and road debris, which can lead to much more expensive repairs.
Is this the same part used on the original Fisker Karma?
While the 2017 Revero is based on the Fisker Karma, parts are not always interchangeable. The Revero underwent significant updates. To ensure a correct fit, you must use a shield specifically listed for the 2017-2020 Karma Revero and not assume a Fisker part will work.
Why can't I just repair my cracked splash shield?
For small, clean cracks, temporary repairs using zip ties or fiberglass repair kits are possible for DIYers. However, for a part that plays a role in aerodynamics and protection, a replacement is the best long-term solution. A repaired shield may not have the same structural rigidity and could fail again, especially at high speeds.
Will a missing splash shield cause my car to overheat?
Potentially, yes. The shield is designed to channel air through the radiator and cooling system. While a missing shield might not cause immediate overheating in casual driving, it could contribute to higher operating temperatures during hot weather or demanding situations by disrupting the intended airflow.
