You may feel more shaking, hear loud noises, or notice a bumpy ride if your motor mounts go bad. You might also see damage or see the engine move. Many people ask, “How do I know if my motor mounts are bad?” Some signs are strong shaking and banging sounds, mostly when you start or stop the car. These engine mount problems can show up early. Watch for any new sounds or feelings in your car. If you ask, “Are motor mounts important?”—yes, they hold your engine in place and help stop shaking.
Key Takeaways
Watch for excessive vibrations in your car. Strong shaking can indicate bad motor mounts. Check them if you feel new or stronger vibrations.
Listen for unusual noises like thumping or clunking. These sounds often mean the engine is moving too much and may signal failing motor mounts.
Look for visible wear on the mounts. Cracks, corrosion, or fluid leaks can show that your motor mounts need attention.
Notice engine movement when you accelerate or shift gears. If the engine rocks or shifts, it may be a sign of mount failure.
Act quickly if you notice any symptoms. Timely repairs can prevent further damage and keep your car safe and running smoothly.
Symptoms of Bad Motor Mounts

When you know the symptoms of bad motor mounts, you can spot problems early and keep your car running smoothly. Here are the most common bad engine mount symptoms you might notice:
Excessive Vibrations
You may feel strong vibration in your seat, steering wheel, or even the floor. This is one of the most obvious symptoms of bad motor mounts. When the engine mount fails, it cannot absorb engine vibration, so you feel it inside the car. These vibrations often get worse when you start the engine or when you accelerate. Sometimes, the vibration can be so strong that it feels like the whole car is shaking. Unlike vibrations from unbalanced wheels or a misfiring engine, vibration from bad motor mounts often feels harsher and more direct. You might even notice the gear shifter moving or hear things rattling inside the cabin.
Tip: If you feel new or stronger vibrations, especially when idling or speeding up, check your motor mounts soon.
Unusual Noises
Bad engine mount symptoms often include weird noises. You might hear thumping, clunking, or impact noises when you start the car, shift gears, or speed up. These sounds happen because the engine moves more than it should and hits other parts. Impact noises from the engine can sound like metal hitting metal. If you hear these noises, especially during quick starts or stops, your engine mount may be failing.
Thumping sounds
Clunking noises
Impact noises from the engine making contact with other parts
Rough Ride
A rough ride is another sign of engine mount failure symptoms. When the mounts cannot hold the engine steady, the car feels bumpier, especially on rough roads. You may notice the car shakes more than usual, and the ride feels less smooth. This bumpier ride can make driving less comfortable and may even make it harder to control the car.
Visible Wear
You can sometimes see visible signs of wear on the engine mount. Look for cracks, corrosion, or warping on the rubber parts. If you see the rubber flaking or splitting, or if the mount looks misaligned, these are bad engine mount symptoms. Fluid leaks near the mounting points can also mean the mount is damaged. A quick visual check can help you spot problems before they get worse.
Cracks or tears in the rubber
Corrosion or rust on the metal parts
Warping or bending
Fluid leaks near the mount
Misaligned or tilted engine
Engine Movement
If you notice the engine moving more than usual, this is a clear sign of engine mount failure symptoms. When you rev the engine or shift gears, watch to see if the engine rocks or shifts. Too much movement can cause other problems, like broken hoses or damaged wires. Engine movement can also lead to excessive vibration, impact sounds from the engine, and even poor handling. If the engine looks like it is not sitting straight, or if you see it move when you press the gas, the mount may have failed.
Note: Engine movement can cause other parts to wear out faster and may lead to bigger repairs if not fixed quickly.
Knowing these symptoms helps you catch bad motor mounts early. If you notice any of these signs—vibration, weird noises, a rough ride, visible signs of wear, or engine movement—get your car checked by a professional.
Are Motor Mounts Important?
What Motor Mounts Do
You may ask if motor mounts matter for your car. The answer is yes, they are very important. Motor mounts help keep your engine safe and steady. They hold the engine in one spot and stop it from moving too much. Here are the main jobs of motor mounts:
