What are the symptoms of a broken engine mount?
3 Answers
Symptoms of a broken engine mount include: 1. Obvious engine vibration when reversing; 2. Noticeable shaking when starting the vehicle; 3. Significant engine vibration when the engine is cold, with noticeable improvement after warming up; 4. Steering wheel vibration during idle and noticeable brake pedal vibration. When the engine is running, it generates certain vibrations. The engine mount contains rubber components to eliminate resonance produced during engine operation. Some mounts also feature hydraulic oil pressure reduction, all serving the same primary purpose. If the engine mount is damaged, the vibrations from the engine will cause the entire vehicle body to vibrate.
As someone who commutes by car daily, I've experienced firsthand what happens when engine mounts fail. At idle after starting, the entire car begins shaking violently - the steering wheel and seats vibrate so intensely that even a phone placed on the dashboard bounces. During acceleration, the car feels like it's dancing, with particularly severe shaking when shifting gears or climbing hills. Turning on the AC makes it worse - the vibrations double in intensity, accompanied by occasional clunking noises. Once I delayed repairs until the engine actually sagged, damaging the exhaust system and costing me a fortune. My advice: get to a repair shop immediately if you notice abnormal vibrations to check the engine mounts. Don't let it deteriorate to the point of compromising driving safety. Regular maintenance can prevent this issue and ensure smoother driving.
As someone who frequently deals with cars, I've seen many symptoms of engine mount failure. During idle, the vibration inside the car is very noticeable, with both the steering wheel and floor trembling—it feels like a minor earthquake when things quiet down. The body shake becomes significantly worse during acceleration, especially in the low RPM range, and the vibration intensifies several times when the AC compressor kicks on. Aging engine mounts can cause the engine to sag and may be accompanied by metallic rattling noises. Ignoring this issue can lead to vibrations transmitting to the chassis or drivetrain components, causing further damage. It's recommended to replace them with high-quality mounts and use a multimeter to check the engine gap during inspection. Make it a habit to regularly inspect the mounts for cracks and avoid driving fast in rainy conditions to prevent accelerated wear.
