Why is my Mercedes shaking when I accelerate?

Oceanside Motorsports • March 13, 2025

If your Mercedes is shaking during acceleration , it may be a sign of underlying mechanical faults that need to be addressed urgently. Disregarding the issue may cause further damage and expensive repairs. 

In this blog, we will discuss the typical causes of this phenomenon and how skilled mechanics for Mercedes repair services at Oceanside Motorsports can diagnose and repair the issue.

Common Causes of Shaking During Acceleration

Worn-Out or Unbalanced Tires

Uneven tire wear, imbalanced tires, or out-of-alignment wheels may cause vibrations that become worse as you increase your speed. If the vibration begins at a specific speed and increases, your tires may be the culprit. Inspect for obvious damage, bulges, or uneven tread wear, and make sure your tires are properly inflated. At Oceanside Motorsports, professional mechanics can inspect the wheel balancing and alignment for you.

Worn-Out Transmission or Engine Mounts

Engine and transmission mounts hold these heavy parts in place, but they wear out with time. When worn, they permit too much movement, causing vibrations upon acceleration. Symptoms are excessive engine movement, clunking when shifting, and more vibrations during idling. If not addressed, this may lead to other drivetrain problems.

Failing CV Axles or Joints

CV joints carry power from the transmission to the wheels but eventually wear out. When they fail, they produce intense vibrations that become worse during acceleration, particularly at high speeds. Clicking sounds when turning and grease leaking from CV boots are typical signs of impending failure. Replacing worn-out CV joints can improve smooth driving.

Suspension or Steering Issues

Worn-out ball joints, tie rods, or bushings may cause vibrations, particularly on acceleration. They support your vehicle, and when damaged, they result in poor handling and uneven tire wear. A pull to one side of your vehicle or excessive play in the steering means you need to have your vehicle inspected. Alignment and suspension repairs can avoid further damage.

Driveshaft or U-Joint Problems

Rear-wheel-drive Mercedes vehicles use the driveshaft to send power, and if damaged, it produces vibrations. Worn-out U-joints or an unbalanced driveshaft cause clunking sounds and shuddering that gets worse with velocity. If you detect a lot of play or visual damage, then it’s time to inspect. Letting this happen can result in drivetrain failure.

Brake System Problems

Distorted rotors or jammed calipers may create shaking during acceleration from a standstill or upon braking. Braking causes a pulsating feel, uneven pad wear, or a burning odor close to the wheels, indicating problems. Though brakes are not necessarily connected with acceleration, faults here can nevertheless result in vibration. Maintenance on a regular basis will save repairs that are very expensive.

Bad Fuel or Ignition System

A misfiring engine may result in noticeable vibration when accelerating. Faulty spark plugs, deteriorating ignition coils, or dirty fuel injectors may result in incomplete combustion. Symptoms are the Check Engine Light, acceleration hesitation, and decreased fuel economy. Repairing ignition or fuel system problems returns performance and avoids additional damage.

How to Fix the Shaking Issue

Schedule a Professional Inspection

The best method of diagnosis for shaking problems is to bring your vehicle to a professional Mercedes repair such as Oceanside Motorsports. Their expert mechanics employ high-tech diagnostic equipment to identify the specific problem. A complete check-up prevents underlying problems from being overlooked. Timely diagnosis helps avoid further damage and expensive repairs.

Perform Regular Maintenance

Regular maintenance prevents costly mechanical issues before they begin. Maintaining oil changes, spark plug replacement, and tire rotation ensures optimal performance. Transmission fluid checks and brake pads are also important to the life of your vehicle. Regular maintenance keeps your Mercedes in top condition.

Address Issues Immediately

It can result in larger, costlier repairs later if unusual vibrations are ignored. Immediately have it looked at by a professional once you feel shaking. Minor issues, such as a misaligned tire or deteriorated mount, become worse if neglected. Acting in a timely manner ensures safety and avoids more harm.
