Why Does My Car Shake At 70 Mph? Common Causes And Solutions

“Why does my car shake when I hit 70 mph?” is a common question among drivers, and there are several key reasons behind this issue that we’ll explore. One prominent factor contributing to this unsettling sensation is the presence of sticky brake calipers. When your brake calipers become sticky or stuck, they can cause an unwanted vibration in your car, particularly noticeable in the steering wheel when you reach speeds over 70 mph. This vibration can be unsettling and potentially unsafe, making it crucial to address this issue promptly. To ensure your safety and a smooth driving experience, it’s essential to understand the various reasons your car may shake at higher speeds and take appropriate measures to address them.

If you’re experiencing a noticeable shaking sensation in your car when driving at high speeds, it’s essential to diagnose and address the underlying issues to ensure your safety and vehicle’s performance. This shaking may stem from a deficiency in power, fuel delivery, or oxygen supply to the engine. To pinpoint and resolve these issues effectively, you should inspect and potentially replace critical components such as the spark plugs, fuel filter, and air filter. By doing so, you can restore your car’s smooth operation and enhance its overall performance during high-speed driving.

“Why does my car shake at 70 mph but not at 80 mph?” Many drivers wonder about this phenomenon, and the answer often lies in the condition of your car’s tires and how engine problems manifest at different speeds. When your car shakes or vibrates at a specific speed, such as 70 mph, it may indicate that your tires are out of balance. Tire imbalance is a common culprit behind vibrations that occur only at certain speeds. The uneven weight distribution in imbalanced tires can lead to oscillations that become noticeable within a specific speed range. On the other hand, engine-related issues typically become more apparent as your vehicle’s speed increases. This means that if your car isn’t shaking at 80 mph, the engine is likely not the primary source of the problem, and it’s advisable to start by having your tires balanced to address the issue.
