Driving with Broken Motor Mounts

Motor mounts in your car provide a simple but critical job. They depict the place where the chassis and the engine meet. They’re usually made of a mix of metal and rubber. They will degrade over time due to wear and tear, so is driving with broken motor mounts safe? and what are the signs and symptoms of poor motor mounts that you can look for?

Simply put, you can drive for a long time with faulty motor mounts, but they will become increasingly ineffective at keeping the engine in place and damping vibrations as time goes on. As a result, you will begin to hear and feel annoying noises and vibrations.

A faulty motor mount can cause substantial engine damage and have a significant impact on the vehicle’s performance.

What Are Motor Mounts Used For?

Motor mounts also called engine mounts, serve as a connection between the engine and the car’s body. Engines are extremely cumbersome. Engines with eight cylinders can weigh up to 700 pounds. There’s a lot of force to control when you consider the quantity of energy released by internal combustion and the spinning of the crankshaft.

Mounting the engine in place is an option, but it comes with its own set of issues. Even if the engine is secured, vibrations will still be generated, which will pass through the chassis and make the ride uncomfortable. Furthermore, the vibrations could break out engine parts, causing them to self-destruct.

The chassis and the engine are connected via rubber or fluid-filled mounts. They absorb engine vibrations and prevent them from migrating to the chassis, as well as absorb vehicle movement and keep the engine balanced.

Each wheel of a four-wheel car has its own suspension point. Consider the motor mounts as the fifth suspension point for a different perspective.

Driving with Broken Motor Mounts: Is It Safe?

Even if your motor mounts start to fail, you can still drive, but you won’t be able to experience a hassle-free or smooth ride. When the engine mounts begin to fail, there are a few things to keep an eye out for:

#1 When driving, unwanted vibrations and noises happen

The rubberized portion of the motor mount minimizes vibration and shocks, which is especially important while accelerating over uneven terrain. You’ll still be capable of driving when the rubber goes off, but you’ll hear vibrations, which are plainly annoying.

These vibrations can cause wear and tear on multiple elements around the engine, in addition to being an annoyance to the ears. These vibrations will get more powerful as your motor mounts deteriorate over time. When you find something like this happening, it’s better to have them fixed or replaced by an auto mechanic or yourself.

#2 The engine in motion

One of the purposes of the motor mount, in addition to absorbing vibrations, is to keep the engine fixed in place. You’ll be able to hear the car’s engine moving a little while changing gears, applying brakes, or accelerating if your motor mounts start to fail. It can also damage other parts of the car if it becomes too intense.

Your automobile may even begin to shift to the side as the weight that the motor mounts were kept in place no longer holds equally, causing your vehicle to veer to the side.

#3 Noises of rattling

You’ll hear loud rattling, clunking, or banging noises if your engine mounts are damaged, especially when you speed. It’s a symptom that the engine’s motor mounts have begun to deteriorate, and the engine isn’t properly anchored.

What Causes Motor Mounts to Break Over Time?

The following are some of the most common reasons and causes for motor mount failure over time:

#1 Excessive use without routine maintenance

It’s a good idea to have your motor mounts and engine examined by a mechanic or yourself at least once every few months or years. Excessive usage without regular maintenance will inevitably lead the motor mounts to collapse, as they will begin to age. You’ll notice the rubber starting to wear out and the metal starting to rust as they get older.

#2 Driving dangerously

While driving, be courteous and aware of your surroundings. Applying the brakes too rapidly, or accelerating too quickly, for example, will result in violent motions and vibrations, which will harm your motor mounts.

#3 Inadequate installation

A car mechanic should install motor mounts professionally and correctly. They will certainly cause problems if they are not fitted in the proper position and angle.

#4 Mistakes and accidents

After an accident, it’s especially necessary to have the motor mounts repaired because they may have shifted out of position, weakening the engine’s connection.

#5 Handling uneven terrain

Your engine mounts will generally wear out sooner than the average 5-7 years if you travel a lot over uneven and rough terrain. This is because uneven routes will cause them to encounter greater vibration, wear, and tear.

How Long Can You Drive If Your Motor Mounts Are Faulty?

If you’ve started to notice vibrations and know they’re coming from the motor mounts, you shouldn’t drive for long with them in this state. However, an engine mount usually lasts for around 5-7 years of driving, so if you haven’t had them replaced in that time, you should have them checked or replaced.

By damping vibrations, the rubber component of the motor mount guards against them. When the rubber section wears out, the metal part stays attached to the engine and does its role of securing it for a long time, however, it no longer provides much vibration protection. When engine mounts become fully separated from the engine, which takes several years, they are considered completely worn out.

How Much Does A Motor Mount Repair Cost?

Good motor mounts are pricey, ranging from $220 to 570 dollars based on the condition of the old motor mounts as well as the vehicle’s type and make. Although some may be able to go for as cheap as $50.

Motor mounts are pricey, but they are justified when you realize that making them out of cheap, inferior materials will only detract from their primary function of providing a solid barrier to protect the engine.


Is it possible to drive with a damaged motor mouth? Sure, but it’s always best to be cautious than sorry. Motor mounts are an important aspect of any vehicle’s engine, and they should be maintained regularly to guarantee that you can drive safely.
