2017-2019 Karma Revero Suspension Strut: Noises, Leaks, and Compatibility Warnings
This guide covers common failure symptoms, replacement costs, and the critical Short-Long Arm (SLA) suspension detail for the 2017-2019 Karma Revero.
- Compatibility is critical: These struts only fit 2017-2019 Revero models with the standard Short-Long Arm (SLA) suspension.
- Always replace struts in pairs (both front or both rear) to ensure vehicle stability and predictable handling.
- A wheel alignment is mandatory after strut replacement to prevent uneven tire wear and handling problems.
- Key failure signs include clunking noises over bumps, excessive bouncing, fluid leaks on the strut body, and cupped tire wear.
Symptoms of a Failing Suspension Strut
A worn or failing strut can compromise the Revero's handling, safety, and ride quality. Look for these common signs.

- Clunking or Banging Sounds: A hollow clunking or banging noise, especially when driving over bumps or uneven road surfaces, is a classic sign of a bad strut. This is often caused by worn internal components or loose strut mounts.
- Creaking or Popping When Turning: If you hear a creaking, popping, or binding sound when turning the steering wheel, it could point to a failing strut bearing, which is part of the overall assembly.
- Excessive Road Noise/Vibrations: A strut that is no longer damping properly can transmit more road harshness and vibration into the cabin, leading to a rougher, noisier ride.
Driving and Handling Issues
- Excessive Bouncing: After hitting a bump, if the car continues to bounce up and down, the struts are likely worn out and no longer controlling the spring oscillations.
- Nose-Diving and Squatting: Worn front struts can cause the front end of the car to dip excessively during braking. Similarly, bad rear struts can allow the rear to squat during acceleration.
- Swaying or Body Roll: You may feel the vehicle swaying or leaning more than usual during turns or lane changes, indicating a loss of stability. This can feel like the car is less controlled and less responsive.
Visual Signs
- Fluid Leaks: Struts are filled with hydraulic fluid. If you see oily or greasy residue on the body of the strut, it means a seal has failed and the fluid has leaked out, rendering the strut ineffective.
- Uneven Tire Wear: A bad strut can cause tires to bounce on the road surface, leading to a distinctive "cupping" or scalloped wear pattern on the tire tread. It can also affect wheel alignment, causing wear on the inner or outer edges of the tires.
Compatibility Warning: The 2017-2019 Karma Revero uses a specific Short-Long Arm (SLA) front and rear suspension architecture. It is critical to ensure any replacement strut is designed for this exact system. Using an incompatible part can lead to poor fitment, unsafe handling, and damage to other suspension components.
Known Issues, TSBs, and Recalls
While no recalls or Technical Service Bulletins (TSBs) directly pertaining to the suspension struts on the 2017-2019 Karma Revero were found during research, the vehicle has been subject to several safety recalls for other issues. These include recalls for non-functional rollover sensors in the airbag system, faulty side impact protection brackets, incorrect rearview mirrors, and defective turn signals. Always check with a Karma service provider or use the NHTSA database to see if a specific vehicle is affected by any open recalls.
Buying a Used Suspension Strut
Given the rarity and cost of new OEM parts for the Karma Revero, a used OEM strut can be a smart purchase. However, careful inspection is key.
🎬 See how a mechanic diagnoses a bad strut or shock.- Physical Inspection: Thoroughly inspect the strut for any signs of leaking fluid—this is an automatic rejection. Check the piston rod for any pitting, rust, or bends that could tear the seals. Ensure the strut body is not dented or damaged, and that the spring is intact with no cracks.
- Mileage and Age: Struts typically have a lifespan of 50,000 to 100,000 miles. For a low-mileage vehicle like a Revero, age can be just as important. Rubber components can degrade over time. A used strut from a low-mileage donor vehicle (e.g., under 40,000 miles) is ideal. Listings for used Revero struts have been seen from vehicles with as low as 13,801 miles.
- Verify Compatibility: Double-check part numbers and confirm the strut is from a 2017-2019 Revero to ensure it's correct for the SLA suspension. A used front left strut has been seen with OEM part number KR041522-187.
- Buy in Pairs: It is essential to replace struts in pairs (both front or both rear) to maintain balanced handling and stability. A new strut on one side and a worn strut on the other can make the vehicle unpredictable.
Cost Breakdown
Replacing suspension struts on a luxury vehicle like the Karma Revero can be expensive. Aftermarket options are virtually non-existent, making OEM parts the primary choice.
| Part Type | Estimated Cost (Per Pair) | Notes |
|---|---|---|
| New OEM | $1,000 - $2,000+ | Sourced from a Karma dealer. This is the most expensive but guaranteed-fit option. |
| New Aftermarket | Not Generally Available | The low production volume of the Revero means major aftermarket brands do not typically produce replacement struts. |
| Used OEM | $500 - $800 | Based on individual used strut listings around $295 each. Offers significant savings. Price depends on condition and mileage. |
| Shop Labor | $400 - $800 | Labor typically runs 2-4 hours for a pair of struts. An alignment is also required, adding to the cost. |
| Total (with Used OEM) | $900 - $1,600 | Includes parts, labor, and a wheel alignment. |
Pro Tip: When replacing struts, it's highly recommended to also replace related components like the strut mounts, bearings, bump stops, and dust boots. These parts wear out at a similar rate and are much easier to replace while the strut is already disassembled.

Do I need a wheel alignment after replacing struts?
Yes, absolutely. A strut is a structural component of the suspension, and replacing it will alter the vehicle's alignment angles (camber, caster, and toe). Failure to get an alignment will result in poor handling, pulling to one side, and rapid, uneven tire wear.
Can I replace just one strut?
No, you should always replace struts in pairs (both front or both rear). A new strut will have different damping characteristics than the old one on the opposite side, leading to an imbalance that can negatively affect handling, braking, and stability.
Is it safe to drive with a bad strut?
It is not recommended. While the car may be drivable, a failing strut significantly compromises your vehicle's ability to handle emergency maneuvers and can increase your stopping distance. A severely worn or broken strut can lead to a loss of control, making it unsafe to drive.
How can I confirm my Revero has the SLA suspension?
All 2017-2019 Karma Reveros were built with a Short-Long Arm (SLA) independent suspension on both the front and rear axles. This was a standard feature of the vehicle's aluminum spaceframe chassis.
