As the engine of your vehicle, the motor mount plays a crucial role in keeping everything running smoothly. These sturdy components connect the engine to the car’s frame, stabilizing the engine and absorbing vibrations to provide a comfortable driving experience. But what happens when a motor mount goes bad? Can you still drive your car, or is it a serious issue that needs immediate attention?
In this comprehensive guide, we’ll explore the signs of a bad motor mount, the potential dangers of driving with one, and how to get it fixed to keep your vehicle running at its best.
What is a Motor Mount?
A motor mount, also known as an engine mount, is the component that secures the engine in place within the vehicle’s frame. These mounts are typically made of a combination of rubber and metal, with the rubber element designed to absorb the vibrations and shocks generated by the engine during operation.
The primary function of a motor mount is to:
- Stabilize the engine: Prevents the engine from moving around excessively, which could cause damage to other components.
- Absorb vibrations: Dampens the vibrations and shakes produced by the engine, resulting in a smoother, more comfortable ride.
- Maintain alignment: Keeps the engine properly aligned with the transmission and other drivetrain components.
Most vehicles have between two and four motor mounts, depending on the make, model, and engine configuration. While a single worn-out mount may not be an immediate cause for concern, multiple damaged mounts can lead to significant problems.
Symptoms of a Bad Motor Mount
So, how can you tell if your motor mounts are failing? Here are some common signs to watch out for:
- Excessive Engine Movement: If you notice the engine moving around more than usual, especially during acceleration or gear changes, it could be a sign of a bad motor mount.
- Unusual Noises: Damaged or worn-out motor mounts can cause a range of noises, including clunking, rattling, or thumping sounds from the engine bay, particularly when starting the engine or while driving.
- Increased Vibrations: As the motor mounts lose their ability to absorb vibrations, you may feel more engine shakes and tremors transmitted through the steering wheel, floor, or seat.
- Poor Handling: Faulty motor mounts can affect the vehicle’s handling, making it feel less responsive, unstable, or wobbly, especially at higher speeds or when cornering.
- Visible Wear: Inspect the motor mounts visually for signs of cracking, deterioration, or detachment from the engine or frame.
Dangers of Driving With a Bad Motor Mount
While it is technically possible to continue driving with a bad motor mount, it is not recommended, as it can lead to a range of serious issues:
- Engine and Transmission Damage: Without the proper support and stabilization provided by the motor mounts, the engine and transmission can shift, causing them to strike other components. This can result in significant and costly damage over time.
- Loss of Control: The excessive engine movement caused by a bad motor mount can make the vehicle more difficult to control, especially during braking or cornering, increasing the risk of an accident.
- Accelerated Wear on Other Components: The extra stress and vibrations caused by a faulty motor mount can prematurely wear down other parts of the vehicle, such as hoses, belts, and suspension components.
- Safety Hazards: In extreme cases, a completely failed motor mount could cause the engine to break free from its mountings, leading to a catastrophic failure that could result in a serious accident.
How Much Does It Cost to Fix a Bad Motor Mount?
The cost to repair a bad motor mount can vary depending on several factors, including the make and model of your vehicle, the number of mounts that need to be replaced, and the labor costs in your area.
On average, you can expect to pay between $200 and $500 to replace a single motor mount. However, if multiple mounts need to be replaced, the total cost can quickly rise to $500 or more.
It’s important to note that ignoring a bad motor mount and continuing to drive your vehicle can lead to even more expensive repairs down the road, such as engine or transmission damage. Therefore, it’s crucial to address the issue as soon as possible to avoid further complications.

Is Replacing Engine Mounts a Big Job?
Replacing engine mounts is generally considered a moderately complex repair, but the difficulty can vary depending on the specific vehicle. In some cases, the job can be done relatively quickly by a skilled mechanic, taking around 1-2 hours. However, in some vehicles, the engine may need to be partially or fully removed to access the mounts, which can significantly increase the labor time and complexity of the repair.
It’s important to have the job done by a qualified automotive technician, as they will have the necessary tools and expertise to perform the repair safely and effectively. Attempting to replace the motor mounts yourself without the proper knowledge and equipment can be dangerous and may lead to further damage to your vehicle.
How Serious is a Leaking Engine Mount?
A leaking engine mount is a serious issue that should not be ignored. The rubber components of the mount can deteriorate over time, leading to cracks and holes that allow fluid to leak out. This fluid, which is typically a mixture of engine oil and coolant, can then drip onto other engine components, potentially causing further damage.
A leaking engine mount can lead to the following problems:
- Increased Vibrations: As the mount loses its ability to absorb vibrations, you may experience more engine shakes and tremors, which can accelerate the wear on other components.
- Engine Misalignment: The leaking fluid can cause the engine to shift out of alignment, leading to issues with the transmission, driveline, and other related systems.
- Potential Fire Hazard: Leaking fluids near hot engine components can increase the risk of fire, posing a serious safety hazard.
If you suspect a leaking engine mount, it’s crucial to have it inspected and repaired as soon as possible to prevent further damage and ensure the safe operation of your vehicle.
Frequently Asked Questions
What happens when motor mounts go bad?
When motor mounts go bad, the engine can move around excessively, causing damage to the engine, transmission, and other related components. This can lead to increased vibrations, noises, and poor handling, as well as the potential for catastrophic engine failure.
How much does it cost to fix a motor mount?
The cost to fix a bad motor mount typically ranges from $200 to $500 per mount, depending on the make and model of the vehicle. If multiple mounts need to be replaced, the total cost can quickly add up to $500 or more.
