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 significantly impact the vehicle’s performance.

What Are Motor Mounts Used For?
Motor mounts, also called engine mounts, connect 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, passing through the chassis and making 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 recklessly
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 noticed vibrations and know they’re coming from the motor mounts, you shouldn’t drive with them in this state for long. However, an engine mount usually lasts for around 5-7 years of driving, so you should have them checked or replaced if you haven’t had them 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 secures 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 and the vehicle’s type and make. However, 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 providing a solid barrier to protect the engine.
How to Prevent Motor Mounts from Breaking
One way to prevent motor mounts from breaking is to pay attention to the regular maintenance and upkeep of the vehicle. For example, checking the engine and transmission mountings should be done regularly. This can help identify any signs of wear or damage before it becomes an issue.
- Inspect engine mounts regularly for signs of fatigue or wear, and replace them as soon as possible if any issues are found to prevent further damage.
- Make sure the engine is properly mounted and aligned when installing it in a vehicle, as misaligned mounts can lead to premature failure.
- Ensure all bolts and fasteners for securing motor mount brackets are properly secured and tightened to their correct torque specifications.
- Avoid overloading your engine with excessive weight, as this can increase stress on the motor mounts and cause them to fail prematurely.
- Use higher quality aftermarket motor mounts when replacing worn-out factory units, as these often feature upgraded components designed to withstand increased stress levels than stock parts.
- Check the condition of exhaust system mounting points during routine maintenance; exhaust leaks can cause vibration that could damage the motor mount brackets over time if not addressed promptly.
- Keep an eye out for any fluid leaks around the transmission or engine area; if there are any obvious signs of oil leakage, be sure to have it inspected by a certified mechanic right away before it starts to affect your vehicle’s performance or lead to potential damage to the motor mounts themselves or other surrounding components.
