Why My Car Shakes When Accelerating in First Gear

February 20, 2024

When your car shakes when accelerating in first gear, it can be alarming and could indicate a serious issue that needs to be addressed as soon as possible. There are several reasons for this shaking, ranging from problems with the engine, transmission, or suspension system. It’s important to get this problem fixed right away as it can lead to expensive repairs down the road if left untreated.

The most common cause for this shaking is due to a failing or damaged motor mount. These are the components that connect the engine to the rest of the vehicle and can be worn out or broken, causing excessive movement during acceleration. Other causes for this shaking include worn out spark plugs or ignition coil, a malfunctioning fuel injector, or a damaged clutch disc. These issues are often hard to pinpoint, so it’s best to visit a professional auto technician for diagnosis and repair.

Another reason for this shaking is due to a faulty exhaust system. If the exhaust system is clogged or has damage, it can interfere with the flow of gases, leading to vibrations during acceleration. This is usually easy to fix, and a mechanic will be able to inspect the exhaust system for damage and make any necessary repairs.

A damaged or loose axle is also a common cause of shaking when accelerating. Axles are responsible for transferring power from the engine to the wheels, so they need to be in good condition to provide a smooth ride. A qualified mechanic can replace or repair any axles that are worn out or damaged.
