REASONS YOUR CAR VIBRATES WHEN ACCELERATING

Cars are one of the largest conveniences of our time that often goes underappreciated until drivers experience performance issues in their vehicles. One common performance issue that nearly all drivers report is, “my car vibrates when accelerating or driving at high speeds.” Since this is such a pervasive issue, it’s common for drivers to continue driving despite the concerning symptom. If you experience this issue in your own car, it’s important to bring it to a specialist for an inspection right away to spare your car further strain and damage and save yourself some money in unnecessary repairs. Here’s what you should know about car vibration upon acceleration and what you can do to prevent it.

The Most Common Causes of a Vibrating Car While Driving

It is your automotive specialists’ primary mission to determine the cause of the vibration that you’re experiencing in your car; once the source of the problem is detected, it can be resolved with the appropriate treatment interventions. These are the most common causes of vibration, or shaking, that you should know about:

Spark plug issues

Spark plugs are critical for ignition and combustion, they ignite the fuel/air mixture that makes your car go. The plugs themselves, or failing electrical wiring, put the engine under a great amount of strain and may be the reason behind the vibration and shaking.

Dirty air or fuel filter

As we mentioned, a perfect fuel/air mixture is an important for optimal performance. If the air or fuel filters are clogged, then the engine can’t get enough air or fuel and becomes strained. This leads to shaking when the car attempts to accelerate.

Engine mount failure

The motor mounts holding your engine in place are instrumental to the quality of your drive. If a motor mount is cracked, collapsed, leaking or damaged at all, it can cause your engine to vibrate intensely.

Brake wear

The brake system can encounter problems now and then that surprisingly leads to vibration while driving. Although the symptoms usually occur when applying the brakes, you may also experience them upon acceleration.

Suspension or steering issues

Faulty or failing suspension or power steering components are often the sources of vibration during acceleration. As the car generates speed, it puts more pressure on the suspension components – especially if the road conditions aren’t optimal.

Wheel and tire care

Proper wheel care entails tire rotations, filling tire pressure, wheel alignment, and wheel balancing. If any of these tasks aren’t upheld, it can lead to vehicle vibration.

The Importance of Preventive Maintenance and Ongoing Automotive Care

Preventing your car from vibrating when accelerating, or shaking at all for that matter, can not only make you feel safer in your car but keep your car performing optimally year round, which leads to the need for fewer repairs. These are a few other valuable byproducts of preventive maintenance:

  • Retains a car’s reliability
  • Retains a car’s value
  • Extends a car’s longevity
  • Upholds performance standards
  • Saves money in unnecessarily expensive repair bills

In terms of preventive care, there are a number of things you can do to keep your car from vibrating while accelerating. Here are a few suggestions that you should adhere to for optimal performance results and less intense and costly repair work:

  • Look for an automotive shop that specializes in the particular type of car you drive
  • Stay on top of routine maintenance and repair tasks
  • Don’t let concerning symptoms go unattended

When your car begins to vibrate at all while you drive, it can be concerning for your safety depending on where the original source of the issue is coming from. For instance, if the issue is related to the engine, you may eventually experience engine stalling, misfiring, or other serious symptoms related to engine performance.

Mercedes-Benz Gear Shift Problems

Mercedes-Benz is a brand known for their durability, longevity, and sophistication; however, even the most highly reliable brands can let us down once in a while. Whether you own an automatic or a manual transmission Mercedes, particular models have been known to undergo transmission issues—particularly with the gear selectors. When a gear selector fails, it can be frustrating to deal with the inconvenience and sometimes the problem is expensive to repair. Keeping up with ongoing vehicle maintenance can greatly reduce the risk of gear selector issues, although sometimes the cause of such issues has nothing to do with our diligence as car owners and everything to do with manufacturing and design. It helps to know how you as a Mercedes owner can help prevent such issues from occurring, but first let’s take a look at what gear selector issues look like and the potential causes.

Symptoms of gear selector failure

It’s not always easy to differentiate gear selector issues from other similar problems in a Mercedes-Benz, but it helps to have an idea of what to look for. If your gear selector is failing, you might notice grinding noises while shifting gears, or clicking sounds coming from the gear selector itself. It is also common to experience difficulty shifting smoothly from one gear to the next—which mainly occurs in automatic engines. Drivers with gear selector failure have also noticed difficulty going from drive to reverse smoothly without stopping fully in neutral.

Potential Causes

While the symptoms of transmission problems mimic the symptoms of other potential issues, these are some of the common reasons why you could be having issues with your gear selector.

Transmission is worn

Your transmission is made up of a system of intricate parts including bands, linkages, cables, and gears, all of which wear out over time. It is important to keep your Mercedes well-maintained, including frequent tune-ups and inspections, fluid changes and top-offs, and replace any parts that are especially damaged or worn. By doing these things and following your recommended maintenance schedule set forth by the dealership, you can prevent transmission wear from leading to gear selector failure.

Failing valve body

The valve body is a critical element of an automatic transmission. It is responsible for keeping hydraulic fluid flowing through the transmission so that the proper gear-shifting mechanism can be enabled while going from one gear to the next. If the valve body fails, then the gear-shifting mechanism also fails. It is important to have your automotive specialist thoroughly inspect the valve body to determine where the root of gear-shifting issues is coming from. If the valve body is failing or damaged, then it will need to be replaced by a professional.

Defective Manufacturing

Although Mercedes vehicles are exceptional, every brand has its downsides and manufacturing issues. Mercedes vehicles have been known to display some transmission difficulties, which in the past have lead to several class-action lawsuits due to customers’ dissatisfaction with faulty transmissions. Other transmission issues that have been known to come up in Mercedes vehicles are shifter module or brake light switch failure, both of which can lead to gear-shifting problems.

The importance of an accurate diagnosis

When you experience transmission issues, the best thing to do is schedule an appointment with a professional Mercedes specialist. It is imperative to employ the correct troubleshooting methods and order of operations to rule-out potential causes of the problem. To accurately diagnose an issue, it is important to have the proper equipment and specialized skills working with Mercedes vehicles—otherwise, you might end up spending hundreds in diagnostic fees alone.
