Few things are as perplexing or unnerving as a sudden failure in your car’s system while you are driving down the road. Your vehicle depends on specific components to operate. If the parts break down, your car will suddenly cease to work, and you may find yourself on the side of the road or in a hazardous situation.


If your car suddenly stops in the middle of driving, call AA Auto Tech right away. We can send out a tow truck and bring your vehicle into our service center for an auto inspection. To schedule service, contact us at 651-437-2218.

1. Empty Fuel Tank

When your randomly car shuts off while driving on the road, the first thing you should check is your car fuel tank. You cannot drive a car with no fuel. Thus, looking at the fuel gauge may save you from trying to figure out what is wrong with the vehicle. If fuel loss continues to happen while you are driving, you may need to get an AA Auto Tech mechanic to check your fuel gauge. It may be displaying a false reading.

2. Alternator Failure

An error alternator is one of the most common reasons your car stops working while you are driving. The alternator loses the ability to charge the electrical system, which causes the power to drain.  Therefore, you may have to recharge the alternator before operating the vehicle so that the alternator does not consume the battery's power again. A malfunctioning alternator can cause an unexpected shutdown, putting you in a difficult situation on the roads.

3. Worn Out Ignition Switch

The ignition switch supplies power to the starter motor, ignition system, and engine controls. A faulty switch can prevent these systems from getting power, resulting in an engine that won’t start. A worn ignition switch can disrupt the supply of power to vehicle electronics. Worn switch contacts can momentarily cause a loss of voltage to vital systems, such as the engine controls.

4. Clogged Fuel Pump


If your fuel pump gives up on you, you will not be able to restart your engine.

Be careful what fuel you feed your car. More often than not, a simple mistake of pumping petrol into diesel cars, or pumping diesel into petrol cars is enough to screw things up. If you don’t hear it and you can’t start your car, it’s likely that you have a malfunctioning fuel pump. Your best bet is to get your vehicle towed to AA Auto Tech to get it checked out.

5. Crankshaft Position Sensor

All modern vehicles contain a crankshaft position sensor. It is a component for monitoring the crankshaft’s rotational speed and position. It also sends a report to the engine control unit so that the crankshaft can make the right adjustments if any component is malfunctioning. There is a wide range of failed sensor symptoms that you should observe. Many vehicles stop functioning if this component fails to send accurate signals.
