What Causes a Car to Stop While Driving

If your car dies while driving it'due south best not to panic. Panicking will merely make y'all unable to recall clearly and brand the state of affairs worse. Virtually of us have been in this situation whether we similar it or not. If yous've been in this situation recently and you're trying to detect out what happened, we'll be discussing the common reasons why your car dies while driving and how to diagnose it. Only before that, here are things you lot should practise if you lot find yourself in this situation:

• What to do if your car dies while driving
• Common causes
• How to diagnose
• How to avert a motorcar dying while driving
• Conclusion

What to Do If Your Machine Dies While Driving

In that location are four steps that you should practice if you find your engine has died while you're driving:

1. Guide the car to the side of the road. If your automobile was moving when its engine died, it volition probably withal have enough speed and momentum for you to coast to the side of the road. If your car died while you lot were at a consummate halt, you lot should push it or ask for assist to push button it to the side of the road. Park out of the fashion of other drivers to brand sure you – and everyone around you – is safety.
2. Turn on emergency blinkers. This way, drivers around you will be aware that yous've cleaved down and tin can give y'all some space. Who knows, maybe a good samaritan will find you're in an emergency and stop past and lend you a hand.
3. Endeavour to start the car, if information technology does, so that'southward nifty. You lot can drive immediately to the nearest repair shop to encounter what went wrong. We would suggest you lot to bulldoze in the right lane, then you tin can hands get to the shoulder should your car breakdown over again.
4. Call for help. If your car won't kickoff again and y'all're not sure what to do, it's time to telephone call for help. You lot can either call a friend or a family that can assistance, or call for a towing service to at least get you off the road first. Diagnosing and fixing a car by the side of the road can be tricky and uncomfortable, we wouldn't arraign you if y'all want to just get your auto home first.

Common Causes Why a Car Dies While Driving

Before we learn how to diagnose a machine that dies while driving, here are some of the well-nigh common causes y'all might want to know:

1. Bad Battery (and weak alternator)

This is quite a common event. If your battery dies while information technology'southward driving, information technology wouldn't be able to feed electricity to a variety of important components, leading to your auto shutting off while driving. For example, your engine needs the ignition organisation to create a spark to showtime the combustion process. The ignition arrangement gets its energy from your battery, so if your battery dies, the ignition organisation will cease to work too.

A flat battery takes no more than than fifteen minutes to modify, and a fresh battery should cost no more than $200 even for the premium ones. Most batteries will final you bet iii to v years, simply they may get flat prematurely. This segues u.s.a. perfectly to the second reason:

2. Bad Alternator

The alternator is in charge of charging your automobile'south battery as you drive along. If the alternator has gone bad, then information technology won't be able to charge your battery properly. This then leads the battery to go flat even if it's still new. We'll hash out more than how to diagnose an alternator below. If you have a bad alternator, frequently your car volition bear witness symptoms such every bit dimmed headlights or interior lights while idling.

If you practice have a bad alternator, then replacement cost tin exist quite costly. Depending on your motorcar's brand and model, a brand new alternator can cost between $300 – $7000. However, you can salve some money by getting a remanufactured (or refurbished) i for effectually $200 – $300.

Y'all can besides save some money by doing information technology yourself thus eliminating the need for you lot to pay for labor costs. However, alternators volition be a bit catchy to install since you lot demand to attach the serpentine or bulldoze belt onto it. If this is done incorrectly and there isn't enough tension, your alternator won't work properly. We don't recommend doing this unless y'all know what you're doing or a DIY enthusiast that's willing to follow the proper steps.

3. Faulty Fuel Pump

A fuel pump is responsible for, well, pumping fuel into your engine. A fuel pump that has gone bad won't be able to feed the needed corporeality of fuel to your engine, or worse, it won't be able to practice it at all. If this is the crusade of your motorcar shutting off, yous will ofttimes discover your car jerking as you lot bulldoze along.

Most fuel pumps are designed to terminal for up to 10 years, but for one reason or another, they may neglect prematurely. The average replacement price for a fuel pump is $450. However, the price varies between $250 – $1000 depending on your car brand and model.

4. Faulty Mass Airflow Sensor

Your engine needs to take in air to start the combustion process in the engine. Within the intake system, your car has a mass airflow sensor (MAF) which tells your ECU how much air to put in. If this sensor goes bad, your car will accept in the incorrect amount of air into the engine, disrupting the combustion process. In some scenarios, it can pb to the motorcar shutting off. Similar to the fuel pump trouble, you volition notice your car jerking before it dies on you. A MAF will toll yous around $450 to replace.

5. Bad Ignition Coils or Spark Plugs

Recall how your battery is needed to power the ignition coils and spark plugs? Well, these parts could go bad over time and causing your motorcar to shut off. It's non very common as cars with a bad ignition system usually struggle to turn on in the first place anyway. However, if your auto is misfiring and and so it dies on you, and then yous might have an ignition system problem. About unremarkably with the ignition coils and spark plugs.

Spark plugs volition usually need to be changed around xx,000 – thirty,000 miles and should cost you no more $10 to supervene upon. While ignition coils will last for around 100,000 miles, and a gear up of ignition coils should cost no more than than $450, including labor cost.

How to Diagnose a Car That Dies While Driving

If your auto dies while driving, there are several possible scenarios. Paying attention to this could help you diagnose what's wrong with your car:

1. Automobile Dies While Driving and There's A Alarm Low-cal

If your automobile dies and you lot see a warning lite on the dashboard, this can be i of 2 things. If you lot meet a check engine light, then there's something wrong with your engine. The trouble varies from ignition coils to faulty air intake sensors, which y'all will need to determine by using an OBD reader to come across the error codes.

Meanwhile, if yous see a bombardment alarm lite, so the problem is related to your electric organisation. Most likely it's your alternator that has gone bad or the belt has snapped. An alternator is used to charge your battery with electricity as y'all drive forth. If your alternator has gone bad, then the machine is consuming more electricity than it is making. As a result, your battery will run flat and your car will shut off.

To check this, you volition need a voltmeter to test your battery's volt. A good for you battery should read at least 12.iv volts when the machine is off. If you're lucky and the car can get-go, a running automobile with a healthy alternator should annals at to the lowest degree 14 volts. Whatsoever less than that then yous have an alternator and bombardment consequence.

What Else Should Y'all Check?

If your bombardment alert light is on, here's a few more things that you could bank check:

• Check the bombardment terminals and connections. It's not uncommon to discover corrosion around the bombardment terminals and connections. Corrosion might crusade the battery to exist unable to charge properly, leading to a flat bombardment as you drive. A loose cable might also cause this.
• Check the drive belt, since the alternator runs on the drive belt. If it's loose, worn, or installed improperly then it could touch the alternator's ability to charge the battery.
• Check the electronic system circuit, including wires, connectors, fuses, and fusible links. See if there is impairment to whatsoever of them, as this could touch on the entire charging system.

You should as well endeavor to diagnose why your auto won't restart. If it's caused past a flat battery, then you can nevertheless start your auto once more past using jumper cables with the help of a friendly passerby'southward automobile. This will hopefully be enough for yous to get to the nearest repair shop.

If your motorcar can offset once more and it's an alternator problem, nosotros'd recommend driving without the A/C and headlights on (if you've broken down during the 24-hour interval, that is). Shutting off your car's electrical components will prolong the battery's life when you drive and should give y'all more juice to get home or to the nearest repair store.

2. Car Dies While Driving and The Lights Cut Off

The root of this problem is largely similar to when your automobile dies and you lot see a check bombardment alert light. If your auto shuts off and the electronic components are completely off, open up your motorcar's hood and inspect your motorcar'south battery. See if in that location are any loose cables or corrosion. You volition demand to tighten a loose cablevision or supercede information technology if necessary. Meanwhile, corrosion on your battery's terminals or cables can be cleaned by using a mixture of baking soda and water.

A faulty ignition switch might also cause this, but your headlights should still turn on. Another thing yous might want to check is the fuse. If y'all take a blown fuse, some electrical components might still work but it's preventing you from turning the machine on.

3. Car Dies After Running for a Few Minutes

If your car starts just fine only then dies after a few minutes, you could exist dealing with one of the post-obit bug:

• A bad ignition coil or ignition module
• Faulty crankshaft position sensor
• Bad fuel pump

These components may fail as the car warms up later on you lot turn it on. You lot can bank check a bad ignition coil yourself using either a multimeter or a spark tester, depending on the type of your ignition curl. As for the crankshaft position sensor, you will demand a multimeter and yous tin watch the video beneath on how to examination it:

4. Car Dies at a Full Stop or Idling

If you were driving just fine but your motorcar suddenly dies equally you reach a full stop, information technology could exist caused by a faulty idle air control (IAC). The IAC is responsible for controlling your engine's idling rotational speed. Over fourth dimension, clay may build up inside the IAC and jamming it closed, stalling your auto while idling. Another common problem would be IAC's circuit or solenoid has failed. Yous tin larn how to check and supervene upon your IAC in the video below:

What Else Should Y'all Cheque?

If your car dies as yous reach a full stop or when idling, at that place are a few more possible reasons. Another common problem is with the Mass Airflow Sensor (MAF). This sensor is responsible for determining the airflow rate that should enter your engine. A faulty sensor would mean your machine'due south Engine Control Unit of measurement (ECU) is feeding the wrong amount of air. If your engine doesn't get enough air, then it could stall.

Other possible causes include faulty manifold absolute pressure level, engine coolant temperature, throttle position sensor, and intake vacuum leak. When these parts neglect, y'all will nigh likely meet a bank check engine lite on the dashboard. If at that place'southward a check engine calorie-free, you can easily pinpoint the problem by using an OBD reader and crosscheck the error codes. You tin either buy an OBD reader for less than $500 or infringe one from your local repair shop or a friend.

v. Car Dies While Driving simply It Can Start Again

This problem usually happens when at that place's an consequence with your fuel system. The possible causes are as follows:

• Clogged fuel filter.A clogged fuel filter ways your auto is unable to feed the necessary amount of fuel to the engine. Well-nigh fuel filters are supposed to exist changed every two years or 24,000 miles. Although they can last for up to 50,000 miles in some cars. Effort to remember if you've had your fuel filter changed recently.
• Faulty fuel pump. A faulty fuel pump would hateful your machine is unable to feed fuel to your engine properly. Most fuel pumps tin terminal for up to 15 years, only they may fail prematurely. If your machine jerks before information technology shut off then you might want to bank check your car'southward fuel pump.
• Bad fuel pressure level regulator. Your fuel system needs pressure to operate, a faulty regulator means there isn't plenty pressure level in the organisation. You will need a fuel pressure level exam kit to test this, and you lot can larn how to practise it in the video below:

6. If Your Car Shuts Off Suddenly

In about of the scenarios in a higher place, you lot will notice signs before your car dies. Either a alert light on your dashboard may appear, a jerking or misfiring engine, or electrical components acting funny. However, if your car just completely shuts off out of nowhere as if someone has switched it off, you could be looking at these possible problems:

• Faulty crankshaft position sensor or circuit.
• Faulty ignition switch
• Other faults in the ignition organization, which includes the battery, anchor resistor, ignition control module, or ignition coil if your car has a unmarried scroll with a distributor.

If your car is completely unable to restart, then you may have a cable or a excursion that has completely failed. If your car tin start once again after it cools downward, so you can troubleshoot by checking section 5.

How to Avoid Your Car Dying While Driving

A lot of the common causes can be avoided by simply taking proper care of your car. Virtually of the parts mentioned in a higher place are replaced regularly during a routine service. Here are some of our tips:

• Call up to check your battery regularly. A skillful bombardment should annals between 12.iv – 12.ix volts when the car is off and to a higher place fourteen volts while idling. We would suggest every three months or so is enough, but monthly would exist great. Additionally, you should likewise keep a lookout for damaged cables and corrosion.
• Check your alternator if your car is over five years old or has done more than 150,000 miles. Alternators are supposed to final a long time, ordinarily upward to 150,000 miles. If your car has washed more than than that and you oasis't had your alternator replaced, information technology would be wise to check it regularly in apprehension.
• Routine air filter maintenance. Ordinarily, a dusty air filter won't shut off your car entirely. At its worst, information technology will "only" cause your auto to jerk or misfire as you drive along. Notwithstanding, leaving a muddy air filter uncleaned or unreplaced could shorten your MAF sensor's lifespan. Be sure to supersede your air filter when necessary, which is usually around 10,000 miles. They should cost you no more than $xx to replace.
• Change your ignition coil and spark plugs. These are the two parts that need to be replaced regularly in your ignition arrangement. Well-nigh of the other components should last quite long and yous need non worry. Most of the time, your mechanic will notify you lot when it'due south fourth dimension to change the ignition coils and/or spark plugs.

Heed to What Your Car is Telling Y'all

A lot of the time, your car won't suddenly die on you lot and will testify symptoms before it dies while driving. Listen to what your auto is telling you and you can avert having to deal with a car shutting off while you're driving.

• Bank check Engine or Warning Light. This one is adequately obvious and a very straightforward fashion for your car to tell yous that there's an issue. If you lot see this light, be sure to take it to diagnose it, you lot can do it yourself or do it at a trusted repair shop. This should be done immediately equally there's something incorrect. If the check engine calorie-free flashes rather than lit continuously, you should cease driving immediately.
• Dim interior or headlights. This would indicate that there's something incorrect with your car's electric system. It may be a battery, alternator, or fuse issue. If you run across this, exist sure to check your car's electrical system to avoid further problems.
• Car jerking equally you drive. If your auto jerks or misfires while you lot drive, then in that location's a myriad of possible issues that we've listed down in a dissimilar article. In any case, a jerking car is not normal and you should check it to find out what the result is. This way, you lot can stop the trouble from getting more serious to the point where your car breaks down.
• Colored fume from your exhaust. Unless your car is a diesel, and then the fume it produces should exist clear and mostly odourless. Thick white smoke from your exhaust indicates a serious problem and can lead to the car breaking downwardly if not addressed immediately.

Car Dies While Driving Conclusion

Believe me when I say that having your car die on you equally you drive forth is an unpleasant experience and is a massive inconvenience. I used to drive a 1976 Mini Cooper and I call back I had more than breakdowns than problem-free journeys. Anyhow, hopefully, later reading this nosotros've helped you lot sympathize better why your motorcar died, how to diagnose information technology, and besides the possible repair costs you might be facing.
