Motor mount replacement typically runs between $300 and $1,500 per mount, depending on which mount fails, your vehicle's make and model, and whether the job requires removing the engine

A motor mount is a rubber-and-metal assembly that holds your engine in place and absorbs vibration. When one fails, you'll feel severe shaking at idle or when accelerating. The cost to fix it depends almost entirely on how accessible that particular mount is on your car. A front mount on a sedan might take a technician 45 minutes. The same mount on a truck with a tight engine bay might take three hours. Labor rates vary by shop and region, but expect $100 to $200 per hour.

Parts themselves are usually $50 to $300 each, though some luxury or performance vehicles run higher. The real expense is labor time. If the shop has to remove the engine subframe, transmission, or other major components to reach the mount, you're looking at the upper end of that range or beyond.

Key Takeaways

  • Motor mount replacement costs $300 to $1,500 per mount, with labor making up most of the expense on difficult-to-reach mounts.
  • The location of the failed mount determines labor time more than anything else — front mounts are usually faster than rear or transmission mounts.
  • Many vehicles have multiple mounts, and shops often recommend replacing all of them at once to avoid repeat visits, which increases total cost.
  • Getting a second estimate is worth your time, because labor estimates for the same job can vary by $200 to $400 between shops.

Why location matters more than the part itself

Your vehicle has three to four motor mounts depending on the model — typically one on each side of the engine, one at the rear, and sometimes one under the transmission. The front mounts are usually the most accessible and therefore the cheapest to replace. A technician can often reach them without removing anything else.

Rear mounts and transmission mounts are another story. On many vehicles, the shop has to lift the engine slightly, remove the subframe, or drop the transmission to access them. That's where a $400 job becomes a $1,200 job. Before you get a quote, ask the shop specifically which mount has failed — they can tell you from a visual inspection or by feeling the engine movement when the car is running.

Labor time varies sharply by vehicle design

A Honda Civic with a failed front motor mount might take 1 to 1.5 hours of labor. A BMW or Audi with the same failure can take 3 to 4 hours because the engine bay is tighter and other components are in the way. Trucks often fall somewhere in between — more space than a compact car, but the engine is larger and heavier, which means more care during removal.

This is why two shops can give you vastly different quotes for the same vehicle. One shop's technician might know a faster route to the mount; another might follow the manufacturer's recommended procedure, which takes longer. Neither is wrong — they're just different. Getting quotes from two or three shops in your area gives you a realistic range for your specific car.

Whether to replace one mount or all of them

If only one mount has failed, you can replace just that one. However, many shops recommend replacing all mounts at the same time, especially if your vehicle is older or has high mileage. The reasoning is sound: if one has worn out, the others are likely close behind, and you'll be back in the shop in six months for the next one.

Replacing all mounts at once costs more upfront — typically $800 to $3,500 depending on your vehicle — but you avoid multiple labor charges. If you're on a tight budget, replacing only the failed mount is a legitimate choice. Just understand that you may need to return for additional replacements sooner than you'd like.

What to expect during the repair

The shop will lift your vehicle, locate the failed mount, and remove the bolts holding it to the engine and frame. On accessible mounts, that's straightforward. On difficult ones, the technician may need to support the engine with a jack or hoist while removing the mount, then carefully lower it back down once the new one is installed.

The entire job usually takes one to four hours depending on location and vehicle design. You should be able to pick up your car the same day. After the repair, the shaking at idle should stop when ready, and acceleration should feel smoother. If shaking persists, the shop should re-inspect — sometimes a second mount has failed, or the original diagnosis was incorrect.

Comparing quotes from different shops

When you call for an estimate, tell the shop which mount is failing (if you know) or describe the symptoms — shaking at red lights, clunking when you shift into gear, or movement you can see under the hood. Ask for a written estimate that breaks down parts cost and labor hours separately. This lets you compare apples to apples.

A shop charging $150 per hour for 2 hours of labor plus a $100 part is different from one charging $200 per hour for 1.5 hours plus a $150 part, even though both might quote you $400. The first shop may be slower or more cautious; the second may have a faster technician or a different approach. Neither quote is automatically better — you're paying for different things.

When motor mount failure is a warning sign of other problems

Motor mounts fail from age and wear, but premature failure sometimes signals that something else is wrong. If your mounts are only a few years old and one has already failed, the engine may be running too rich, producing excess vibration that's wearing them out faster. A check engine light or rough idle can point to this.

Similarly, if you've had a collision or accident, a motor mount may have been damaged even if you didn't notice it at the time. Before authorizing the repair, ask the technician whether they see any signs of impact or other damage that might explain the failure. It won't change the repair cost, but it might reveal a bigger issue that needs attention.

Frequently Asked Questions

Can I drive with a bad motor mount?

Yes, but not comfortably or safely. A failed mount causes severe vibration that can damage other engine components over time, and the excessive movement can stress transmission mounts and engine oil lines. The shaking also makes the car harder to control. Most shops recommend fixing it within a week or two, not when ready, but not indefinitely.

Do all motor mounts fail at the same time?

Not usually. Mounts wear at different rates depending on driving habits, engine load, and how much vibration each mount absorbs. The front mounts typically fail first because they handle the most movement. However, if your vehicle is old or has very high mileage, multiple mounts may be close to failure, which is why shops often recommend replacing them all together.

Is motor mount replacement covered by warranty?

Factory warranties typically cover motor mounts for three years or 36,000 miles, whichever comes first. Extended warranties vary — some cover them, some don't. If your vehicle is still under warranty and a mount has failed, contact your dealer for a quote before going to an independent shop. Dealer labor is usually more expensive, but the warranty may cover it.

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

OEM (original equipment manufacturer) mounts are made by your vehicle's manufacturer and typically cost more but are may provide to fit perfectly. Aftermarket mounts are made by third-party suppliers and usually cost less, but quality varies. Most shops use aftermarket mounts unless you specifically request OEM. Ask your technician which they're quoting before you commit.

Will replacing motor mounts improve my gas mileage?

No. Motor mounts don't affect fuel consumption. However, if a failed mount has caused your engine to run rough or misfire, fixing it might improve mileage slightly by allowing the engine to run more smoothly. The improvement, if any, would be minor — usually a few miles per gallon at most.
