7 Most Common Car Diagnostic and Repair Issues You May Face

Car repair is one of those activities that many people consider to be complicated and time-consuming, but it doesn’t have to be this way. By understanding some basic car diagnostic and repair issues that are common with cars, you can save yourself from wasting money on unnecessary repairs or missing out on necessary repairs simply because you don’t know the signs to look for.

From the outside, your car may seem to be in perfect working condition, but on the inside, it could be riddled with problems that you won’t know about until something goes wrong. That’s why you should always be aware of the most common car diagnostic and repair issues so you can troubleshoot them before they become major problems. Here are some common issues that you should watch out for in your vehicle.

  1. Check Engine Light

If the Check Engine Light comes on, it’s a sign that something may be wrong with your vehicle. If you’re unsure about what to do next, visit your local auto repair shop for expert advice.  They can test your engine system using diagnostic equipment like an OBD II scanner and a data code reader. The only time when the light should stay on is if there is an actual problem or concern detected by the computer.

  • Excessive Oil Consumption

The engine is designed to provide lubrication for critical components of the engine, but when there is excessive oil consumption, or low oil pressure, it can lead to potential problems. Oil serves as a lubricant and coolant for the engine. As oil circulates through the engine, it provides a barrier that prevents friction from damaging other parts. It also helps keep metal surfaces clean by trapping dirt particles before they can do any damage.

  • Misfire

A misfire is typically a symptom of an issue in the fuel system, including problems with the fuel injectors, spark plugs or even the air intake. Misfires can be caused by engine wear and tear, improper fuel mixture, or even a bad timing belt. If you experience a misfire problem it’s best to have your car looked at by a mechanic.

  • Low Fuel Pressure

When the fuel pressure is too low, this can lead to a number of issues with your vehicle. Your engine may not start, it might stall during acceleration or deceleration, or the engine might make knocking noises. One way to check for low fuel pressure is to remove the gas cap and look for gas vapor coming out.

It’s important to have your car checked by a professional if you notice any of these symptoms when driving.

  • No Crank/No Start

If you are driving with no crank or no start problems, your most likely culprit is a battery issue. You may have left the lights on, drained your battery due to high electrical load such as running the AC or heated seats, or a number of other reasons. Remember, if you still don’t get any power after checking all of these items, it’s time to bring in the professionals for help.

  • Dead Battery

A dead battery is one of the most common car diagnostic and repair issues that you may face. Fortunately, it’s not too difficult to diagnose a dead battery, so you can head down to your nearest auto parts store for a new battery. The first step in diagnosing a dead battery is to make sure that the engine is off. Then, disconnect all of the accessories from the vehicle. Next, check whether or not there are any lights on inside the car when you open the door.

  • Fluctuating Gas Gauge Readings

A fluctuating gas gauge reading is a common car diagnostic issue. The problem could be as simple as a loose connection or as serious as an internal leak. Either way, it’s important to get the car checked out by a professional so that you can get the problem fixed and avoid driving with an inaccurate gas gauge.

Affordable but Professional Automotive Diagnostic Scanner

While cars are a really great way to get from point A to point B, they do require some work on your part. This can range from changing the oil once in a while to more serious issues like diagnosing your car for problems that need to be fixed.
