Motor mount replacement typically costs between $300 and $1,200 per mount, depending on which mount fails, 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 brake, or vibration that shakes through the steering wheel and cabin. The cost to replace it depends on three things: how many mounts need replacement, how difficult they are to access 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 a second repair in six months. Labor time ranges from one hour for an accessible mount to four or five hours for mounts buried deep in the engine bay, which is where most of your bill comes from.
Key Takeaways
- Parts alone cost $50 to $300 per mount, but labor typically runs $200 to $900 depending on how hard the mount is to reach on your vehicle.
- Dealerships charge 30 to 50 percent more than independent shops for the same work, though they may use original manufacturer parts.
- A failing motor mount creates engine movement you can see and feel, but it does not damage the engine itself if caught within a few weeks.
- Replacing one mount costs less than replacing all mounts, but if two or more are visibly worn, replacing them together often saves money on labor.
What the parts themselves cost
Motor mount parts range from $50 to $300 each, depending on whether you buy an original manufacturer part or an aftermarket replacement. Original parts from your vehicle's manufacturer cost more but come with a longer warranty — often three years or unlimited miles. Aftermarket mounts from brands like Prothane or DEA cost less upfront but may wear faster and come with shorter warranties, typically one year.
Some vehicles have specialty mounts that cost more. Hydraulic mounts, which use fluid to dampen vibration more effectively than rubber alone, can run $150 to $300 per mount. Luxury vehicles and performance cars often use these. If your vehicle has an electronic engine mount that adjusts stiffness based on engine load, replacement parts can exceed $400 each.
The part cost is usually the smaller piece of your bill. Most of your expense comes from the labor required to remove the old mount and install the new one, especially if the mechanic has to remove other components to reach it.
Labor costs at dealerships versus independent shops
An independent repair shop typically charges $200 to $600 in labor per mount, depending on how accessible it is. A dealership charges $300 to $900 for the same work. The difference reflects dealership overhead, technician certification requirements, and the fact that dealerships often use original manufacturer parts as part of their standard practice.
For a straightforward replacement — say, the front engine mount on a Honda Civic — an independent shop might bill one hour of labor at $100 to $150 per hour. A dealership might bill the same hour at $150 to $200 per hour. For a rear mount on a Subaru or a side mount on a V6 engine, labor can stretch to three or four hours because the mechanic must remove the engine subframe, exhaust components, or transmission cooler lines to access it.
Dealerships have one advantage: they can often order the exact original part and have it in stock within a day. Independent shops may need to order parts, which can add a day or two to the repair timeline. If you need your vehicle back quickly, a dealership may be worth the extra cost.
Why labor time varies so much between vehicles
A motor mount on a four-cylinder engine mounted lengthwise (front to back) is usually accessible from the top or side of the engine bay. Replacing it takes 45 minutes to an hour. A motor mount on a transverse engine (side to side) in a compact car, or a mount on a V6 or V8 engine, often requires removing the engine subframe, which can take three to five hours of labor.
Some vehicles require you to remove the wheel well liner, drop the engine slightly using a jack and block, or disconnect the transmission cooler lines just to reach a single mount. Luxury vehicles and newer models with tightly packed engine bays are the worst offenders. A Mercedes or BMW motor mount replacement can cost $1,000 to $1,500 in labor alone because the engine bay is so compact.
Before you get a quote, ask the mechanic how many hours they estimate for your specific vehicle and which components they'll need to remove. This tells you whether you're looking at a one-hour job or a half-day job.
Total cost breakdown by vehicle type
| Vehicle Type | Parts Cost | Labor Cost (Independent) | Labor Cost (Dealership) | Total Range |
|---|---|---|---|---|
| Compact sedan (Honda, Toyota) | $75–$150 | $150–$300 | $250–$450 | $300–$600 |
| Mid-size sedan (V6) | $100–$200 | $300–$600 | $450–$800 | $500–$1,000 |
| SUV or truck | $100–$250 | $250–$500 | $400–$700 | $450–$950 |
| Luxury vehicle (BMW, Mercedes, Audi) | $150–$300 | $600–$1,000 | $800–$1,200 | $1,000–$1,500 |
These ranges assume replacement of a single motor mount. If your mechanic recommends replacing two or more mounts at the same time, add the parts cost for each additional mount but do not double the labor — replacing two mounts in one visit usually costs only 1.5 times the labor of replacing one, because the mechanic has already done much of the setup work.
Signs you need motor mount replacement soon
A failing motor mount produces symptoms you can see and hear. The most obvious is a loud clunk or thud when you shift from Park to Drive, or when you accelerate hard from a stop. This happens because the engine lurches forward or sideways without the mount holding it in place. You may also notice the engine visibly shaking when you look under the hood at idle, or vibration traveling through the steering wheel and seat while driving.
Another sign is that your engine rocks excessively when you rev it in Park. Put your vehicle in Park, have someone rev the engine to 2,000 RPM while you watch from the side, and look at how much the engine moves. A healthy engine moves slightly. A failing mount lets it swing several inches. If you see that, one or more mounts are worn.
Do not ignore these symptoms. A failing mount does not damage the engine itself, but it can cause the engine to contact the frame or transmission, which can crack engine mounts, bend cooling lines, or damage the transmission bell housing. Catching the problem within a few weeks of noticing symptoms keeps the repair straightforward and inexpensive.
When to replace one mount versus multiple mounts
If your mechanic finds that one mount is clearly failed and the others look intact, replacing just that one is the right choice. However, if the inspection shows that two or more mounts are visibly cracked, leaking fluid, or severely compressed, replacing them together often makes financial sense. The labor to remove and reinstall the engine or subframe is the same whether you replace one mount or three, so the additional parts cost is usually worth avoiding a second repair in six months.
Ask your mechanic to show you photos of the mounts they inspected. A mount that is slightly compressed but not cracked can last another year or two. A mount that is visibly split, leaking, or has separated from its metal bracket should be replaced. If you see two or more in that condition, replacing all of them at once saves money overall.
Some shops offer a discount if you replace multiple mounts in one visit — typically 10 to 15 percent off the total labor. It is worth asking.
Frequently Asked Questions
Can I drive with a bad motor mount?
Yes, but not for long. A failed mount causes excessive engine movement and vibration, which can damage cooling hoses, transmission lines, or the engine itself if the engine contacts the frame. Most mechanics recommend having it replaced within a week or two of noticing symptoms. Driving long distances or towing with a failed mount increases the risk of secondary damage.
Do I have to go to a dealership, or can any mechanic replace a motor mount?
Any certified mechanic can replace a motor mount. Independent shops often charge less and can complete the work just as well as a dealership. The main advantage of a dealership is access to original manufacturer parts and the ability to diagnose complex issues on newer vehicles with electronic engine mounts. For most vehicles, an independent shop is a good choice.
Why does labor cost so much more than the part itself?
Motor mounts are often buried deep in the engine bay, requiring removal of other components like the subframe, exhaust system, or transmission cooler lines just to reach them. On some vehicles, the mechanic must partially remove or lower the engine. This setup and removal work takes most of the time, not the actual mount replacement itself.
Will replacing motor mounts fix my check engine light?
Not always. A failed motor mount can cause the engine to move enough to damage sensors or wiring, which triggers a check engine light. Replacing the mount may resolve the light if the sensor damage is minor. However, if the engine contact damaged a sensor or connector, you may need to replace that component as well. Have the mechanic scan the code before assuming the mount replacement will fix it.
Is it cheaper to replace all motor mounts at once, even if only one is bad?
Not necessarily. If only one mount is clearly failed and the others are in good condition, replacing just that one saves money. However, if two or more are visibly worn or cracked, replacing them together often costs less overall because you avoid paying labor twice. Ask your mechanic to inspect all mounts and show you photos before deciding.
