5 Common Car Repairs You Should Not Do Yourself

Years ago, passenger cars were much simpler to repair, or maintain than they are today. This is why some drivers in decades past worked on their own vehicles. Modern automobiles, however, are extremely complex machines, requiring specialized tools, training, and experience to repair them.

While it is tempting for some car owners to try to save time and money by repairing their own vehicles, it is not advisable. People who work on cars, but are not qualified to can jeopardize not only their safety, but also the welfare of other motorists on the road.

In this blog, let’s look at 5 common car repairs that you should not do yourself.

Common Car Repairs by Mechanics

Brake Repair

A car’s brakes seem pretty simple. You press the pedal, and the vehicle stops. However, what is behind that process in modern cars is extremely complex. Brakes are made up of many individual components, all working together. These include brake pads, calipers, rotors, brake fluid, electronic sensors, motors, and a master cylinder.

With the introduction of Automated Driver Assistance Systems (ADAS), your car’s brakes are likely part of a network of computer modules, electronic sensors, motors, and software that run the Anti-Lock Braking System (ABS) Lane Departure System (LDS) or Collision Avoidance Systems. Many of these safety features require post repair calibration to operate correctly.  Because a vehicle’s braking system is such a critical part of its safety features, be sure to have a qualified technician repair it.

Transmission Repair      

Automobile transmissions have always been complicated, but this is especially true today. Because modern transmissions are part of the powertrain control network, classic symptoms like slipping, erratic or hard shifting are generally not transmission malfunctions but rather a sensor providing incorrect data to the powertrain control module and/or transmission control module. Discovering the root cause of these symptoms usually requires advanced specialized training.

In fact, not all mechanics are qualified to do it. If you sense your transmission is slipping, or not shifting correctly, be sure to take the car to a technician who is qualified to diagnose the problem and fix it.

Engine Diagnostics

Today’s vehicles have multiple onboard computers that help monitor and control their performance. If the  Check Engine light appears on your dashboard, this is your car letting you know that something needs attention.

Well-meaning parts store employees can plug a diagnostic reader into a port under the dash and learn from a series of codes why your engine light is glowing. While some people try to interpret a code by looking it up on the internet, correctly repairing the issue is an entirely different skill set. A qualified technician will use specialized tools to analyze which sensors are reporting outside of their acceptable parameters then perform tests to discover why it is occurring.  Pro Tip: The root cause is generally not the sensor which illuminated the “check engine light”.

Car Electrical Repair

 Automobile electrical systems are more complicated today than any other period in the history of vehicle manufacturing. The science of electricity hasn’t changed since Ben Franklin flew his kite in a thunderstorm. But the strategies employed to control nearly every component of a modern car is changing with every model year.  Even simple light bulb functionality requires knowledge of advanced electronic networks.

Be sure to take your car to an experienced, trained mechanic to address any electrical system problems.

Suspension Repair   

Like your car’s braking system, its front and rear suspension play a critical role in keeping you safe.

They are designed to support the weight of the car as it travels down the road. In addition, your car’s steering is dependent upon the front suspension operating properly.

Over time, a vehicle’s suspension parts will wear, and need to be replaced. Because your safety is literally riding on your car’s suspension, be sure it is serviced by people who have been formally trained to repair, perform an alignment and calibrate any affected sensors such as SAS.

Car Starter Issues

One of the most often used components on your car’s engine is the starter. Without it, your vehicle won’t be taking you anywhere.

Starters in most modern cars are attached to the engine in hard-to-reach spots. In addition, many vehicles require that other parts be removed before the starter can be accessed. If your starter is not performing as it should, be sure to take the car to a qualified mechanic who can fix it properly.

When to Consult a Mechanic: Key Signs to Watch For

You should consult your mechanic if you experience any of these common car problems.

• Grinding sounds, or poor stopping performance from the brakes.
• Transmission shifting issues.
• The “Check Engine” light comes on.
• Something goes wrong with the electrical system.
• The car begins to ride rough, or not steering like it should.
• The starter will not engage the engine.
