15 Overlooked Signs Your Car Could Be on the Verge of a Breakdown

Sudden car breakdowns are always heavy on nerves and pockets, but here’s the fact: they are never sudden. Signs are always there as your car starts telling you something inside is wrong. However, the “sudden” breakdown results when you aren’t aware of the signs or choose to ignore them for a long time. Since a stitch in time saves nine, keep the following signs at your fingertips to identify, fix, and prevent severe damage.

Squealing or Unusual Noises

You can always tell when your car starts making a different sound; never ignore it. When you hear the squealing sound, the fan belt is to blame, and you need to replace it before it leaves you stranded on the road. Knocking and grinding sounds indicate rod bearings and front brake pad issues. It’s unsafe to drive a car without resolving issues in both cases.

Warning Lights

Could the sign get any clearer? Kelly Blue Book recently published a study showing that nearly half of the drivers drive with the warning lights on. Remember that these warning lights use computer communication and sensors to indicate the vehicle’s best interest. Sometimes, these lights may illuminate even minor issues like a loose gas cap, but checking the problem quickly can keep a lot of fuss away.

Unusual Odors

According to the American Car Association (AAA), a sweet burning smell is a sign of a coolant leak, while a smoky burning smell may result from a transmission fluid or oil leak. Even the rotten egg smell isn’t always some forgotten lunchbox; it indicates the issues with fuel filters, fuel pressure sensors, or catalytic converters. If you notice any of these, it’s better to check for the leakage to be sure and safe.

Engine Stalling

You must have let out a sigh of relief if your engine restarted after abruptly ceasing once. Well, don’t sit back if it’s repetitive. The engine may stall because of a human error. However, if there hasn’t been any operational mistake, contamination, bad fuel pump, ignition issues, faulty sensors, and clutch problems can be the culprit. Battery, electrical problems, and alternators can also be the reason. Visit a reputable workshop to get these issues fixed.

Vibrations

If you are vigilant and have sharp senses, you can quickly sense even mild vibrations in the steering rod. Vibration and shaking mostly arise from issues with suspension and tires. However, they can also be due to the engine’s inadequate air and fuel supply and bad motor mounts. If these issues are not fixed in time, they lead to more significant troubles.

Hard or Rough Engine Start

Having trouble starting the engine? While your first suspicion is low fuel level, things worsen if that’s not the issue. In that case, your fuel pump is most likely failing, and immediate attention is warranted. You may also need to look for thick oil, slow battery, damaged starter motors, failing solenoid, and worn-out ignition switch. The sooner you pinpoint and troubleshoot the problem, the safer you are.

Fluid Under the Vehicle

Have you witnessed a pool of liquid in the car parking areas once the car is removed from the spot? It’s definitely the leaked car oils or fluids, but the reasons may vary significantly. There is nothing to worry about if the leaked fluid is water since it’s just the air conditioner doing its job. However, a faulty hose will lead to the leak of coolant fluid. 

Similarly, a failing engine gasket, oil pan spill, and crankshaft seal are responsible if the engine oil leaks. Transmission fluids vary in color, but the changes in gear shifting may indicate that the leaked fluid is from the transmission.

Dim or Flickering Lights

Lights get their power from electric sources, and flickering lights indicate a problem with the battery or electric components. The alternator is in charge of recharging the battery and managing other electrical components, which might be the root cause. Delaying fixing this issue will worsen the situation and compromise the safety of everyone on the road.

Transmission Slipping

Transmission is genuinely the working unit of your drive. It is in charge of serving the driver with his desired power rate from the engine. Hence, proper fluids are needed for it to function smoothly, and like any other fluid, you will have to regularly maintain the fluid level and quality to prevent the transmission components from wearing out. If you are facing difficulty while shifting gears or doing so produces unusual noises, it’s better to refill the fluid or flush it before the major breakdown.

Dragging/Slipping Clutch

Clutches know nothing like mood swings, so you must notice if they drag. Clutch drag occurs if the disc and flywheel fail to disengage completely when pressing the clutch pedal in manual cars. It is potentially the issue if you find it hard to put the car in first, reverse gear, or gear changes are noisy.

Uneven Wear Tire

Tires wear over time, no matter how much you try to prevent it. The real cause of concern is when the tire wear is uneven, and one or two are significantly more worn out than the others. As expected, the balancing and alignment issues put more stress on the side, resulting in greater damage.

Overheating Engine

If not fixed, an overheated engine can backfire or explode. Most vehicles will notify you through a warning light when the engine overheats. If not, the thumping sounds, reduced power, and hot-to-touch bonnet are the signs of an overheated engine. Other underlying reasons include inappropriate coolant levels, low engine oil, or cooling system malfunctions. 

Sudden Mileage Changes

It is natural for engines to suck more fuel when there’s an excessive load on the vehicle, electric equipment is running, or the driver changes gears quickly. If none of the above causes are present, defective engine block, poorly inflated tires, dragging brakes, low coolant level, or bad fuel injectors may result in the engine burning more fuel than usual. 

Slow Acceleration

It’s disappointing when pressing the accelerator doesn’t give the expected response. Experienced drivers always know the road conditions or carloads cause the difference. Also, slow acceleration indicates low fuel pressure, clogged fuel system, or air intake problems, which must be fixed.

Unusual and Excessive Smoke

Clear smoke from the tailpipe is normal, but your car needs a proper inspection if the smoke changes color. Blue smoke indicates oil leakage from the engine, as the blue color results from the direct burning of the oil. Similarly, burning coolant or antifreeze makes the smoke turn white. A clogged air filter will turn the smoke black. If not addressed promptly, all these issues may lead to an engine breakdown.
