5 Common Indications of an Engine Issue

American Five Star Auto Repair & Transmission • Mar 25, 2024

When you notice evidence of an engine issue, it’s always best to alert the mechanic right away. This will give you the best chance to prevent the problem from escalating and causing breakdowns and/or more expensive repairs. At American Five Star Auto Repair & Transmission, we provide expert engine repair in the greater Tempe, AZ area. Here’s a look at five common signs of engine trouble.


Check Engine Light

The check engine light is your car's way of telling you that something is wrong under the hood. While it can sometimes be triggered by minor issues like a loose gas cap, it's crucial not to ignore it. A diagnostic scan can reveal the specific problem, which can then be promptly addressed. Common check engine light triggers include issues with oxygen sensors, catalytic converters, and MAF sensors.


Decreased Performance

If your vehicle isn't accelerating as smoothly as it once did or if you notice a decrease in power and efficiency, it could be a sign of engine trouble. This could be caused by various factors, such as a clogged air filter, a malfunctioning fuel pump, or worn-out spark plugs. Addressing these issues promptly can prevent further issues and restore your engine’s performance.


Discolored/Excessive Smoke from the Exhaust

The smoke’s color can provide clues about the underlying issue. Blue smoke commonly suggests burning oil. White smoke might indicate a coolant leak, while black smoke could signal a rich fuel mixture. 


Strange Noises 

One of the most obvious signs that something is wrong with your engine is unusual noises. Knocking, tapping, hissing, or grinding sounds could indicate various issues, and should be promptly investigated. 


Unusual Smells 

Strange odors can also indicate engine trouble. A sweet smell could mean a coolant leak, while a burnt odor might suggest that oil or transmission fluid is leaking. Any unusual smells should be investigated promptly to prevent further damage.

It’s important to get to the shop when you first notice that your car is struggling to fire up as easily as usual. If you delay, the underlying issue may soon escalate and prevent your car from starting at all. At American Five Star Auto Repair & Transmission, our local mechanics are experts at identifying and fixing issues that cause no-start. Here are five common issues that prevent cars from starting up. Dead Battery One of the most frequent culprits for a car that won't start is a dead or weak battery. Common causes of dead batteries include loose/corroded connections, old age, parasitic draws, and leaving on headlights. If you hear a clicking sound when you turn the key or notice dim lights on the dashboard, you may well have a battery issue. Faulty Starter Motor The starter motor is responsible for turning the engine over when you turn the key. If the starter motor is faulty, your car won't start. A sign of a malfunctioning starter is that there’s a grinding noise. Fuel System Issues If there are issues with the car’s fuel system, it may not start. Common fuel-related problems include a clogged fuel filter and a malfunctioning fuel pump. Fuel system problems often cause symptoms such as sputtering and decreased fuel-efficiency. Ignition System Failure The ignition system is crucial for starting your car. Problems with components like the ignition switch, spark plugs, or ignition coil can prevent your car from starting. Symptoms may include a lack of engine turnover or irregular engine firing. Faulty Alternator The alternator charges the battery while the engine is running, and a malfunctioning alternator can lead to a drained battery and difficulty starting the car. Signs of alternator issues include dimming headlights and problems with interior electrical accessories.

Your vehicle's suspension system plays a crucial role in providing a smooth ride and proper stability. Eventually, wear and tear can take a toll on your suspension components, leading to potential safety hazards and a compromised driving experience. When you first notice a symptom of suspension trouble, it’s best to visit the shop for an inspection. At American Five Star Auto Repair & Transmission, our local mechanics are highly experienced with suspension repair in the greater Tempe, AZ area. Here are five signs of a suspension problem. Bumpy or Unstable Ride If you notice excessive bouncing, swaying, or a generally uncomfortable ride, it could suggest problems with your shocks or struts. These components are responsible for absorbing shocks and vibrations, and when they fail, your vehicle's ride quality diminishes. Knocking or Clunking Noises Unusual noises, such as knocking or clunking sounds, when driving over rough terrain can indicate problems with the suspension system. These noises may be a result of worn-out bushings or issues with the shock absorbers. Ignoring these sounds can lead to further damage and compromise safety. Visible Fluid Leaks Leaking shock absorbers or struts can lead to a loss of fluid, affecting their ability to absorb shocks effectively. If fluid is leaking out onto your shocks, there’s a good chance that you’ll need to replace them. Dipping or Nose-Diving During Braking A healthy suspension system helps maintain stability during braking. If you notice your vehicle dipping forward or nose-diving when you apply the brakes, it could signal issues with the front suspension components. Failing shocks or struts can compromise braking performance and overall safety. Uneven Tire Wear In many cases, one of the first signs of a suspension problem is uneven tire wear. If you notice that your tires are wearing out unevenly, particularly on the inside or outside edges, it could be an indication that the suspension components are not properly supporting the vehicle's weight.

Your car's alternator plays a vital role in keeping the electrical system running smoothly. It generates electrical power to recharge the battery and supply electricity to various components in your vehicle. When the alternator malfunctions, it can lead to a host of issues, and potentially leave you unable to start your vehicle. This makes it important to get to the shop at the first sign of trouble. At American Five Star Auto Repair & Transmission, we provide expert alternator replacement and auto electric repair in the greater Tempe area. Here are five symptoms of an alternator problem. Dimming Headlights and Interior Lights A common early sign of an alternator problem is the dimming of headlights and interior lights. The alternator is responsible for providing power to the lighting system, and if it's failing, you may notice a gradual or sudden decrease in the brightness of your lights. Dashboard Warning Light Vehicles are regularly equipped with a dashboard warning light that specifically indicates issues with the charging system. Often shaped like a battery, this light will illuminate if the alternator is not providing sufficient power. Ignoring this warning light may lead to a drained battery and eventually leave you stranded. Strange Noises Unusual noises could be a sign of alternator trouble. A failing alternator may produce grinding, whining, or squealing sounds. These noises can result from worn-out bearings or a loose belt. If you hear any unusual sounds, it's best to have your vehicle inspected promptly to prevent further damage. Difficulty Starting the Engine If you find yourself struggling to start your car, the alternator might be the culprit. A failing alternator may not be able to charge the battery adequately, leading to difficulties starting the vehicle. Flickering or Malfunctioning Electronics The alternator supplies power to various electronic components, such as the radio and power windows. If you notice erratic behavior from your electronics, or if they cease to function altogether, it's a strong indication that the alternator is struggling to provide a consistent power supply.

At the first indication of automatic transmission trouble, you’ll want to get to the shop for an inspection. When transmission issues are ignored, they often escalate quickly and become more costly to address. At American Five Star Auto Repair & Transmission, we provide expert automatic transmission repair in the greater Tempe, AZ area. Here are five warning signs of automatic transmission trouble. Delayed or Rough Shifting One of the most noticeable signs of automatic transmission trouble is delayed or rough shifting. You might feel your car hesitating or jerking when changing gears. This can happen when the transmission doesn't engage smoothly, and it may be accompanied by a clunking sound. If you experience this, it's important to have your transmission checked to prevent further damage. Fluid Leaks Automatic transmissions require a specific type of fluid to operate correctly. If you notice red or brownish fluid leaking from your vehicle, it's a potential sign of a transmission fluid leak. Low transmission fluid can lead to overheating, which can cause serious damage. Slipping Gears Transmission gears are responsible for the power transfer from the engine to the wheels. If your transmission is slipping, you'll feel your vehicle losing power unexpectedly, often with a noticeable increase in engine RPM. Sometimes, gears slip due to problems with transmission fluid. Unusual Noises Unusual noises coming from your vehicle can be a sign of transmission trouble. Listen for sounds like grinding, whining, or clunking when you shift gears or while the car is in neutral. These noises can indicate worn-out or damaged transmission components, and ignoring them can lead to more severe issues down the road. Difficulty in Engaging Gears If you find it challenging to engage gears, whether moving from "Park" to "Drive" or vice versa, it's a clear sign of transmission trouble. This symptom should be brought to the mechanic’s attention so the underlying issue can be pinpointed and addressed before it escalates.

The right level of clean transmission fluid is vital to your transmission’s health. Transmission fluid serves multiple important functions. It provides lubrication, cooling, fluid pressure, and rust prevention. If your transmission fluid becomes contaminated, then significant issues could arise. At American Five Star Auto Repair & Transmission, we provide expert transmission service in the greater Tempe area, including transmission fluid exchanges. Indications of a Transmission Fluid Problem There’s definitely cause for concern if your car suddenly pops out of gear while you’re cruising along. This may happen because pollutants in transmission fluid are impeding the fluid’s flow. In turn, fluid pressure decreases to the extent that the vehicle can’t dependably stay in gear. You might be able to resolve this symptom by getting to the shop for a transmission fluid exchange, which is a maintenance task that should always be completed at the mileage point indicated in your owner’s manual. Other symptoms of polluted transmission fluid include whining noises and grinding. Transmission fluid leaks are a common problem, making it important to be aware of signs that such a leak is present. One potential sign that transmission fluid is leaking is that there’s red-to-pink colored fluid on the pavement beneath your vehicle. Another indication that it’s transmission fluid that’s leaking is that it has a slightly sweet scent. You might also have a leak if you check your transmission fluid level and see that it has gotten very low. Transmission fluid should be checked every month so that you’ll know if your fluid is getting dangerously low or starting to burn. In many cases, transmission fluid leaks arise due to issues such as damaged transmission lines and failing pan gaskets. If a leak is causing your transmission fluid to get too low, then you may notice symptoms such as delayed shifting, grinding, or a burning smell.

If your check engine light comes on, it doesn’t necessarily mean that your engine is nearing total disaster. But you should still get to the shop ASAP for computerized diagnostics so that the problem can be identified and resolved before it escalates. At American Five Star Auto Repair & Transmission, we provide expert check engine light diagnostics and repair in the greater Tempe, AZ area. Here’s a look at six common reasons the check engine light turns on. Failing Catalytic Convertor Catalytic converters do the important job of turning harmful substances in exhaust gasses into less polluting emissions. A faulty catalytic converter is a common check engine light trigger, and may also cause signs of trouble such as decreasing acceleration, a sulfurous odor, and darkened exhaust smoke. Faulty Oxygen Sensor Oxygen sensors monitor how much unburned oxygen is in the exhaust system. An oxygen sensor problem can lead to issues with the catalytic converter. Bad Mass Airflow Sensor Mass airflow sensors help with making sure that fuel is correctly injected with incoming air. Symptoms of a mass airflow sensor problem include poor acceleration, rough idling, and difficulty starting your engine. Faulty Spark Plugs Healthy spark plugs help to optimize engine performance and gas mileage. With bad spark plugs, you may notice symptoms such as worsening acceleration, hard starts, and misfiring. Bad Battery/Charging System If your battery is falling, then low voltage at the computer could lead to an illuminated check engine light. Gas Cap Is Loose/Missing It might seem bizarre that a loose or missing gas cap could trigger the check engine light, but it does sometimes happen. It’s important to keep your gas cap fastened tightly so that gas doesn’t evaporate before it is directed to your engine.

It’s important to get to the shop when you first suspect that engine trouble is brewing. By getting to the mechanic quickly, you’ll have the best chance to address the issue before it escalates and costs a lot more money to fix. At American Five Star Auto Repair & Transmission, our local mechanics are highly experienced with engine repair in the greater Tempe area. Common Symptoms of an Engine Problem If your check engine light comes on, you’ll want to get to the shop for diagnostics. While an illuminated check engine light doesn’t necessarily mean that your engine is on the brink of disaster, it’s still important to pinpoint and address the issue as early as possible. Common reasons the check engine light turns on include problems with catalytic converters, mass airflow sensors, oxygen sensors, ignition coils, and spark plugs. There’s also cause for concern if you notice abnormal sounds coming from under the hood. Knocking/tapping noises can arise due to faulty rod bearings, a lean air/fuel mix, and inadequate lubrication due to low oil. Squealing sounds are often due to serpentine belt problems. Grinding noises may arise because of issues with your power steering or water pump. Another common sign of engine trouble is power loss. If you drive an old vehicle with high miles and it has gradually lost a little power over the years, then you don’t necessarily have a significant problem. But a sudden loss of a substantial amount of power could mean you have head gasket or piston trouble, or another serious issue. You should also get to the shop if you notice discolored/excessive exhaust smoke. Blue-tinted smoke is a sign of an oil leak. Black smoke is symptomatic of too much fuel being burned up. White smoke could mean you have an internal coolant leak and perhaps a blown head gasket.
