Honda Civic Engine Mount Guide for 2017-2024 Models
If your Civic is vibrating or making a clunking noise, a bad engine mount could be the problem.
- Vibration at idle and clunking noises are the most common symptoms of a bad engine mount on a 2017-2024 Civic.
- The factory OEM mounts are fluid-filled for comfort, while most affordable aftermarket mounts are solid rubber and will increase vibration.
- Budget-friendly brands like Anchor, DEA, and Westar have mixed reviews and may not last as long or ride as smoothly as OEM parts.
- Replacing only the failed mount is possible, but inspect the others for wear, as a bad mount puts stress on the entire system.
Is Your Civic Shaking? Signs of a Bad Engine Mount
When an engine mount fails, it can no longer do its job of holding the engine steady and absorbing vibration. You will usually notice one or more of these symptoms. 🎬 Watch: How to locate and diagnose bad engine mounts Many owners report the passenger-side mount is a common part to fail.
- Excessive Vibration: This is the most common sign. You might feel a strong vibration through the steering wheel, seats, or dashboard, especially when the car is idling in Drive or Reverse.
- Loud Noises: You may hear a 'clunk' or 'thud' from the engine bay when you accelerate quickly, shift gears, or put the car into Drive. This sound is the engine moving and hitting against its restraints.
- Engine Movement: If you open the hood and have a friend safely rev the engine while the car is in Park, you might see the engine rock or lurch more than an inch or two.
- Visual Damage: A failed mount might have cracked or torn rubber. The passenger-side hydraulic mount can leak dark, oily fluid when it breaks.
Don't Ignore a Bad Mount
While you can drive with a bad engine mount, it's not recommended for long. The excessive movement can put stress on other parts like hoses, exhaust pipes, and even the other engine mounts, causing them to fail sooner.
Choosing a Replacement: OEM vs. Aftermarket
When replacing a failed engine mount on your Civic, you have a choice between Original Equipment Manufacturer (OEM) parts and aftermarket parts. There are important differences in quality and price.
OEM Mounts
Honda's original mounts are hydraulic, meaning they are filled with fluid to absorb even the smallest vibrations. This gives your car a smooth, quiet ride from the factory. They are made with high-quality, softer rubber for the best comfort. However, they are much more expensive.
Aftermarket Mounts
Aftermarket mounts are a more affordable option. The brands available in the specified price range are typically made of solid rubber, not fluid-filled. This has pros and cons:
- Pro: They are less expensive and can be more durable than the stock hydraulic mounts.
- Con: They do not absorb vibration as well as the OEM parts. You will likely notice more vibration at idle after installing them. This is the main trade-off for the lower price.
Brand Quality Matters
When it comes to aftermarket mounts, you often get what you pay for. Economy brands like Anchor, DEA, and Westar offer a low-cost solution, but owner reviews are very mixed. Some owners report these parts failing quickly or causing significant vibrations right after installation. For a daily driver, many mechanics and owners recommend spending more on the OEM part to maintain ride quality.
How Much Does an Engine Mount Replacement Cost?
The total cost depends on whether you do the work yourself or hire a professional. The passenger-side mount is the most common one to fail.

| New OEM Mount | $250 - $425 |
| Shop Labor | $140 - $210 |

Frequently Asked Questions (FAQ)
Is it hard to replace a Honda Civic engine mount myself?
It is a moderately difficult job. You will need a floor jack to support the engine, a metric socket set, and wrenches. The passenger-side mount is the easiest, while the transmission-side mount requires removing the battery and air intake box. 🎬 Watch: How to replace the transmission-side engine mount It is a doable DIY project for someone with mechanical experience.
🎬 See this step-by-step passenger side mount replacement walkthroughAre there any recalls for 2017-2024 Civic engine mounts?
No, there are no active recalls or Technical Service Bulletins (TSBs) from Honda for engine mount failure on this generation. However, it is a widely discussed problem among owners in online forums.
Why do aftermarket mounts cause more vibration?
Most aftermarket mounts use solid, harder rubber instead of the fluid-filled design of the original Honda part. While this can make them more durable, the harder material transmits more of the engine's natural vibrations into the car's frame, which you feel in the cabin.
If one mount is bad, should I replace all of them?
It's a good idea to inspect the other mounts. A single broken mount puts extra stress on the others, which can cause them to fail too. However, you don't necessarily have to replace them all at once if the others look okay. The passenger-side and lower torque mounts are the most common points of failure.
