Motor mount replacement typically costs between $300 and $1,500 per mount, depending on which mount needs replacement, your vehicle's make and model, and whether you go to a dealership or independent shop

A motor mount is a rubber-and-metal component that holds your engine in place and absorbs vibration as it runs. When one fails, you'll notice excessive engine movement, clunking sounds when you accelerate or shift gears, or vibration throughout the cabin. Replacing it is straightforward work, but the total bill depends on three things: how many mounts need replacement, how hard they are to reach on your specific vehicle, and where you have the work done.

Most vehicles have three to four motor mounts. You rarely need to replace all of them at once — usually one fails while the others still function. However, if multiple mounts are worn, a mechanic may recommend replacing them together to avoid returning for the same job in six months.

Key Takeaways

  • Labor makes up most of the cost, ranging from $150 to $400 per hour depending on your location and shop type, and the job typically takes one to three hours.
  • The mount itself costs $50 to $200 per unit, so a single replacement runs $200 to $600 in parts and labor at an independent shop.
  • Dealerships charge 20 to 40 percent more than independent mechanics for the same work because of higher overhead and warranty coverage.
  • Some mounts are harder to access than others — a mount tucked behind the transmission costs more to replace than one on the side of the engine.
  • Waiting to replace a failed mount can damage the engine, transmission, or suspension, turning a $400 repair into a $2,000 one.

How labor cost breaks down the total bill

Labor is where motor mount replacement gets expensive. A shop charges you by the hour, and the hourly rate varies by location and shop type. Independent mechanics in rural areas may charge $100 to $150 per hour, while shops in cities or dealerships often charge $150 to $400 per hour. The job itself usually takes one to three hours depending on the mount's location and how corroded the bolts are.

A mount on the side of the engine that takes one hour to replace at $150 per hour costs $150 in labor alone. The same mount at a dealership charging $250 per hour costs $250. If the mount is behind the transmission and takes three hours, you're looking at $300 to $1,200 in labor before the part itself is added.

Some shops quote a flat rate for motor mount replacement rather than hourly labor. Flat rates are usually based on how long the job takes according to the manufacturer's service manual. Ask your shop whether they charge hourly or flat rate, and get the estimate in writing before work begins.

What the motor mount itself costs

The part ranges from $50 to $200 depending on whether it's an original equipment manufacturer (OEM) part from the vehicle's maker or an aftermarket part from a third-party supplier. OEM mounts are more expensive but are may provide to fit and often come with a warranty. Aftermarket mounts are cheaper and usually work just as well, though quality varies by brand.

Luxury vehicles and some European cars have more expensive mounts — a mount for a BMW or Mercedes can cost $150 to $250, while a mount for a Honda or Toyota typically costs $50 to $120. Vehicles with electronic engine mounts (which adjust stiffness based on driving conditions) cost significantly more, sometimes $300 to $400 per mount.

Ask your mechanic whether they source OEM or aftermarket parts and what warranty comes with each option. Some shops include a parts warranty; others do not. A warranty that covers the mount for one year or 12,000 miles is standard.

Dealership versus independent shop pricing

Dealerships typically charge 20 to 40 percent more than independent mechanics for motor mount replacement. A job that costs $500 at an independent shop might cost $600 to $700 at a dealership. The difference comes from higher overhead (rent, staff salaries, certification requirements) and the fact that dealerships use only OEM parts and provide manufacturer-backed warranties.

Independent shops often have lower overhead and can source aftermarket parts at a discount, passing savings to you. However, not all independent shops are equal — a shop with a good reputation and certified technicians may charge more than a fly-by-night operation, and that premium is usually worth it.

If your vehicle is still under warranty, check whether the warranty covers motor mount replacement. Some warranties do; others exclude wear items. If covered, you may have to go to the dealership to keep the warranty valid. If not covered, an independent shop is usually the more economical choice.

Why location and accessibility matter

Not all motor mounts are equally accessible. On some vehicles, the mount bolts are straightforward to reach from the top of the engine bay. On others, the mechanic has to remove the wheel, drop the subframe, or disconnect the transmission to reach the mount. The harder the mount is to access, the longer the job takes and the higher your labor cost.

Front mounts are usually easier to access than rear mounts. Side mounts are often easier than top mounts. If your vehicle has a transverse engine (engine mounted sideways), the mounts may be harder to reach than in a vehicle with a longitudinal engine (engine mounted front-to-back). Ask your mechanic how long they estimate the job will take — that estimate reflects accessibility.

Some vehicles require removing other components to access a mount. For example, on some Subarus, you have to remove the intake manifold. On some Fords, you have to drop the engine slightly. These extra steps add time and cost. Your mechanic should tell you upfront if additional work is required.

What happens if you delay replacement

A failed motor mount doesn't make your car undrivable, but it gets worse over time. The engine moves more than it should, putting stress on the transmission mounts, engine oil pan, and radiator hoses. A clunking sound when you accelerate or shift gears is a sign the mount is failing. Excessive vibration in the steering wheel or cabin is another.

If you ignore these signs, the engine can shift enough to damage the transmission, radiator, or suspension components. A transmission mount that fails because the engine was moving too much can cost $500 to $1,500 to replace. A radiator hose that ruptures because of engine movement can cause overheating and engine damage worth thousands of dollars.

The longer you wait, the more damage spreads. A $400 motor mount replacement today can prevent a $2,000 transmission repair six months from now. If you notice clunking or excessive vibration, have a mechanic inspect the mounts within a week or two.

Getting an estimate and comparing shops

Call three to five shops in your area and describe the symptom — clunking when you accelerate, excessive vibration, or visible engine movement. Ask each shop for a written estimate that includes the hourly labor rate or flat rate, the cost of the mount itself, and how long the job is expected to take. Some shops charge a diagnostic fee ($50 to $150) to confirm which mount has failed; others waive it if you proceed with the repair.

Compare the estimates side by side. If one shop is significantly cheaper, ask why — they may use aftermarket parts, have lower overhead, or straightforward be less experienced. If one shop is significantly more expensive, ask what you're paying for — a warranty, OEM parts, or a reputation for quality work.

Check online reviews for each shop before deciding. Look for comments about pricing accuracy, timeliness, and whether the shop stands behind its work. A shop that charges a bit more but has consistently good reviews is often a better choice than the cheapest option.

Frequently Asked Questions

Can I drive my car if a motor mount is broken?

Yes, but not for long distances or at highway speeds. A broken mount causes excessive engine movement and vibration, which can damage other components. Drive only to a repair shop if possible. If you must drive, keep speeds below 45 mph and avoid hard acceleration or sudden braking.

Do all motor mounts fail at the same time?

No. Mounts typically fail one at a time over several years. If one fails, the others are usually still functional but may be nearing the end of their life. A mechanic can inspect all mounts during the repair and let you know if others are worn.

Is it worth replacing all mounts at once if only one is broken?

Not always. If only one mount is clearly failed and the others look good, replace just the failed one. However, if the mechanic finds that two or more are worn, replacing them together saves labor cost because the engine only has to be lifted once.

What's the difference between OEM and aftermarket motor mounts?

OEM mounts are made by the vehicle's manufacturer and are may provide to fit perfectly. Aftermarket mounts are made by third-party suppliers and are usually cheaper but vary in quality. Both work, but OEM mounts often last longer and come with better warranties.

How long do motor mounts last?

Motor mounts typically last 5 to 10 years or 50,000 to 100,000 miles, depending on driving habits and vehicle condition. Aggressive driving, towing, and rough roads wear mounts faster. Regular maintenance doesn't extend mount life, but catching a failing mount early prevents damage to other components.
