2020-2022 Karma Revero & GS-6 Front Engine Brace: Damage Inspection and Replacement
This guide covers the essential inspection points, compatibility warnings, and replacement costs for the front lower engine brace on the Karma Revero GT and GS-6.
- This brace only fits 2020-2022 Revero GT & GS-6 models with the 1.5L BMW engine; it does NOT fit earlier models with the 2.0L GM engine.
- Failure is always caused by collision or underbody impact, not by normal wear and tear. There are no recalls for this part.
- When buying a used brace, it is critical to inspect it for any bends, cracks, or signs of previous repairs, as even minor damage can cause alignment issues.
- A professional wheel alignment is highly recommended after replacing this brace to ensure proper vehicle handling and tire wear.
Compatibility Warning: 2020-2022 Models Only
Warning: This front lower engine brace is specifically for the 2020 Karma Revero GT and the 2021-2022 Karma GS-6 models. These vehicles are equipped with a 1.5L BMW 3-cylinder range-extender engine. This part will not fit the earlier 2017-2019 Karma Revero models, which used a completely different 2.0L GM engine and have a different subframe design.
Symptoms of a Damaged Front Engine Brace
The front lower engine brace is a robust piece of metal that does not wear out or fail on its own. Damage is almost always the result of a front-end collision or a significant underbody impact, such as hitting a curb, large pothole, or road debris.
- Clunking or Popping Noises: A loose, bent, or cracked brace can cause metallic clunking or popping sounds from the front of the vehicle. These noises are most noticeable during acceleration, braking, or when driving over uneven surfaces as the chassis flexes. 🎬 Watch: How to diagnose front end clunking noises
- Poor Wheel Alignment: Because the brace helps lock the subframe geometry in place, any damage to it can lead to persistent wheel alignment issues. The vehicle may pull to one side, and you might experience uneven or premature tire wear.
- Vibrations: While less common for a brace than a failed engine mount, a damaged support can sometimes contribute to unusual vibrations felt through the floor or steering wheel.
- Visible Damage: The most definitive symptom is visible damage. After any significant front or underbody impact, the brace should be inspected for bends, cracks (especially near mounting points and welds), or severe corrosion where the protective coating has been scraped off.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of mid-2024, there are no recalls or TSBs issued by Karma Automotive or the National Highway Traffic Safety Administration (NHTSA) that specifically relate to the front lower engine brace support frame bar on the 2020-2022 Revero or GS-6.
It is worth noting that a recall was issued for these vehicles (NHTSA Campaign Number: 24V379) for an intermittent failure of the front turn signals due to a software communication error. This issue is entirely unrelated to the vehicle's structural components but is the only major recall for this model range.
Pro Tip: The absence of recalls or TSBs for this part confirms that it is not a common failure point. Any issues with this brace will almost certainly be linked to a prior accident or impact.
Buying a Used Front Lower Engine Brace: What to Inspect
Due to the rarity of Karma vehicles, new OEM parts can be extremely expensive and difficult to source, and no aftermarket alternatives exist. A recycled OEM part from a reputable seller is often the most practical and cost-effective solution. A thorough inspection is critical to ensure you are buying a straight, undamaged part.
- Check for Bends or Warping: Lay the brace on a flat, level surface like a concrete floor. It should sit perfectly flat with no rocking. Use a straightedge to check the main spans of the bar for any subtle bends or deformations. Even a slight bend can compromise its structural integrity and cause alignment problems.
- Inspect Welds and Mounting Points: Carefully examine all the welds for any signs of cracking. Pay close attention to the areas where the mounting tabs or brackets are welded to the main bar. Ensure all bolt holes are round and not elongated or damaged, which would indicate it was stressed during an impact.
- Look for Signs of Repair: Be suspicious of any areas that have been re-welded, ground down, or show signs of body filler. A previously repaired brace may not have the same strength as an original part and should be avoided.
- Check for Corrosion: Surface rust on a steel part is usually cosmetic, but you should check for deep, flaking rust or pitting that could weaken the metal. If the part has been scraped bare in an accident, it should be cleaned and painted to prevent future corrosion.
- Verify Compatibility: Double-check that the part came from a 2020-2022 Revero GT or GS-6. An eBay listing for a used part from a 2021 model confirms its availability in the recycled parts market. Compare photos of the used part to your existing one to ensure all brackets and mounting points match exactly.
Replacement Cost Comparison
Replacing the front lower engine brace is typically done as part of a larger collision repair. Prices are estimates and will vary based on your location and the extent of any related damage.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $400 - $700+ | Very difficult to source. Must be ordered through an authorized Karma service provider. Price is an estimate based on similar parts for luxury vehicles. |
| New Aftermarket | Not Available | Due to the low production volume of the Karma Revero, aftermarket manufacturers do not produce this part. |
| Used OEM | $150 - $300 | The most common and cost-effective option. Price depends on condition and availability from automotive recyclers. |
| Shop Labor | $150 - $300 | Labor typically involves 1-2 hours of work. A wheel alignment is highly recommended after replacement, which will add to the cost. |
Installation Overview & Difficulty
Replacing the front lower engine brace is a straightforward but structurally important task.
- Difficulty: 2 out of 5
- Estimated Time: 1-2 hours
- DIY Feasible: Yes, for an experienced DIY mechanic.
The general process involves safely raising and supporting the front of the vehicle, locating the brace under the engine, and unbolting it from the subframe. 🎬 Watch: How to install a front subframe brace Installation is the reverse of removal. It is critical to use a torque wrench to tighten the bolts to the manufacturer's specifications to ensure the chassis is properly secured. Because this part is integral to the front subframe's alignment, a professional four-wheel alignment is strongly recommended after the replacement is complete.
Frequently Asked Questions (FAQ)
Can I drive with a damaged front engine brace?
It is not recommended. A bent or cracked brace compromises the structural integrity of your vehicle's front end. This can negatively affect handling, especially in emergency maneuvers, and can accelerate wear on tires and other suspension components. If the damage is severe, the vehicle should be towed to a repair facility.
Can a bent engine brace be repaired or straightened?
No. Attempting to straighten a bent structural component is unsafe. The metal has already been stressed and fatigued, and it will never regain its original strength and rigidity. A damaged brace should always be replaced with a straight, undamaged part.
What other parts should I inspect if the engine brace is damaged?
An impact severe enough to damage the brace likely affected other parts. Always inspect the main front subframe for cracks 🎬 See this guide on inspecting and repairing subframes or deformation, check the control arms and their bushings, and look for damage to the radiator, A/C condenser, and their supports which are located nearby.
Why can't I find this part for my 2018 Revero?
The 2017-2019 Revero used a 2.0L GM engine and has a different chassis and subframe structure. The front lower engine brace is not interchangeable between the early GM-powered cars and the later 2020-2022 BMW-powered cars. You must source a part specific to your vehicle's year and powertrain.
