How long do Honda motor mounts last?

Most Honda motor mounts last roughly 60,000 to 100,000 miles (about 5 to 8 years) for rubber mounts; hydraulic mounts used in many newer Hondas can exceed 100,000 miles and may last even longer under normal driving. However, driving style, road conditions, climate, and maintenance can shorten or extend that lifespan. This article breaks down typical expectations, what can wear them out, how to recognize failure, and what to expect financially when replacement becomes necessary.

Lifespan expectations by mount type

Overview of typical mount types found in Honda vehicles

The ranges below reflect common configurations used in Honda vehicles. Specific models may vary based on engine family, drivetrain, and manufacturing year.

• Rubber engine mounts: typically 60,000–100,000 miles. Rubber can crack, harden, or separate from the mount housing due to heat, oil exposure, and age.


• Hydraulic engine mounts: commonly 100,000–150,000 miles. These mounts use fluid to dampen vibrations and can fail if the internal seals deteriorate or the fluid leaks.


• Transmission mounts: often 100,000–150,000 miles. These mounts support the transmission and can wear from engine movement and drivetrain loading over time.


• Polyurethane/performance mounts: 40,000–100,000 miles in many applications. They are stiffer and may transmit more vibration, which can affect perceived longevity depending on driving style and model.

Actual life varies with model year, engine setup, climate, maintenance history (such as oil leaks that degrade rubber), and how aggressively the vehicle is driven. Some owners may replace mounts earlier due to noticeable symptoms, while others go longer with careful driving and proper maintenance.

Signs of wear and failure

Common symptoms to watch for

Early detection can prevent secondary damage to the drivetrain or exhaust and may save on labor costs. Monitor for the following indicators:

• Increased engine vibration at idle or during acceleration, especially when the engine is under load.


• Clunking, banging, or rocking sensations when shifting, accelerating, or decelerating abruptly.


• Visible cracking, tearing, or deterioration of rubber mounts, or hydraulic fluid leakage around hydraulic mounts.


• Engine movement or misalignment that feels pronounced compared with how the car behaved previously.

If you notice any of these signs, have a qualified mechanic inspect the mounts as part of a broader drivetrain diagnosis. Early replacement can prevent damage to other components.

Costs and replacement considerations

What affects price and scope

Costs vary by mount type, vehicle model, and labor rates. The following ranges give a general sense of expected prices, though actual quotes will depend on your specific Honda model and local shop pricing.

• Engine mounts (rubber/hydraulic): parts typically $60–$350 per mount; labor $150–$500; total installed range roughly $210–$850 per mount.


• Transmission mounts: parts typically $60–$350; labor $150–$500; total installed range roughly $210–$850 per mount.


• Replacing multiple mounts or dealing with high-torque engines can push total costs higher, with some jobs reaching $1,000–$1,800 or more depending on parts and accessibility.

Prices can vary widely by dealership versus independent shops, geographic region, and whether additional components (such as related brackets or control arms) require service. Replacing mounts in pairs is a common practice to maintain balanced ride quality and vibration control.

Summary

In general, Honda motor mounts tend to last between 60,000 and 100,000 miles for rubber variants, while hydraulic mounts commonly reach 100,000–150,000 miles under typical driving conditions. Longevity is influenced by engine torque, driving style, climate, and maintenance history. Watch for rising vibrations, clunking noises, or visible wear to catch issues early. When replacement is necessary, expect a broad price range based on mount type, the model year, and labor costs, with options varying from aftermarket to OEM parts and from single-mount to multi-mount replacements. Planning ahead and obtaining multiple quotes can help manage the cost of keeping the Honda drivetrain quiet and aligned.

At what mileage do motor mounts go bad?

Engine mounts can last anywhere from 50,000 to 100,000 miles or more, but their lifespan is highly dependent on factors like driving habits, road conditions, climate, and the quality of the mounts. Instead of a strict mileage, it's best to watch for symptoms like increased vibrations, knocking noises, or a visibly tilted engine. Many OEM (original equipment manufacturer) mounts are made of rubber and are designed to be replaced within the vehicle's lifetime.

Factors influencing engine mount lifespan

• Driving habits: Aggressive driving, frequent hard braking, or driving on rough roads can cause mounts to wear out faster. 
• Climate: Extreme heat or cold can degrade the rubber components more quickly. 
• Fluid leaks: Leaks from oil, power steering fluid, or other engine fluids can accelerate the breakdown of rubber mounts. 
• Mount quality: Higher-quality or performance-oriented mounts may last longer than standard OEM mounts, which are often optimized for comfort. 

When to replace your engine mounts
Rather than a specific mileage, pay attention to these signs of wear:

• Excessive vibrations: You may feel more vibration in the steering wheel or seat than usual. 
• Noise: Listen for knocking, clanking, or other unusual sounds, especially when accelerating or shifting gears. 
• Visible damage: Inspect the mounts for cracked or broken rubber. 
• Engine position: Check if the engine appears to be sagging or tilted to one side. 

What to do

• Have your engine mounts inspected regularly, especially around the 75,000-mile mark. 
• If you notice any of the symptoms above, have a professional technician inspect them as soon as possible. 
• If one mount fails, it's often recommended to replace all of them at the same time. 

How much does it cost to replace the engine mount on a Honda CRV?

The cost to replace a Honda CR-V engine mount ranges from approximately $400 to over $1,000, with the average hovering between $400 and $1,000. The total price depends on whether you replace a single mount or all of them, the type of mount (standard rubber vs. hydraulic), the cost of parts (which can range from about $50 to $600 per mount, or higher for premium or dealership parts), and local labor rates.

Factors that influence the cost

• Number of mounts: Replacing all four mounts will cost more than replacing just one. 
• Type of mount: Standard rubber mounts are cheaper than hydraulic or active mounts. 
• Part source:
  • Aftermarket parts can range from about $50 to $200 for a basic mount, and may be more for premium or specialized mounts. 
  • Dealership parts are often more expensive, sometimes costing four times as much as aftermarket options. 
• Labor costs: A professional mechanic's labor rate is a significant factor. The total cost can be between $400 and $1,000, including both parts and labor. 

How to save on costs

• Shop around: Get quotes from different shops to compare labor rates. 
• Consider aftermarket parts: Aftermarket options can be significantly cheaper than OEM parts. 
• DIY (if you have the skills): If you are comfortable with car repair, you can save a lot by replacing the mounts yourself, as a single part can be inexpensive ($50-$200). 

How do you know if your Honda motor mounts are bad?

Signs you need to check or replace the motor mounts are clunking or knocking noise when shifting from park to reverse or park to drive, vibration at idle, vibration at the brake pedal, engine movements, fluid leaks from engine mount, cracked or missing rubber on mount.
