Your vehicle’s engine is the heart of its performance, and when it starts showing signs of distress, quick action can make the difference between a simple repair and a costly rebuild. Ignoring early warning signs can lead to severe damage and even complete engine failure. By paying attention to unusual sounds, performance changes, or dashboard alerts, you can catch problems before they escalate. At Murphy Family Auto Repair, we provide expert engine repair in the greater Mesa, AZ area. Here are five common signs of engine trouble that should be addressed by a mechanic as soon as possible. Check Engine Light Is On One of the clearest warnings of engine trouble is the check engine light illuminating on your dashboard. While it can signal a range of issues—from a loose gas cap to serious engine malfunction—it should never be ignored. The mechanic can use diagnostic tools to pinpoint the exact cause and help you resolve it before it becomes a bigger problem. Unusual Noises from Under the Hood Knocking, tapping, or grinding sounds coming from your engine are never normal. These noises often indicate worn-out components. A knocking sound in particular can be a sign of poor lubrication or misfiring, which can cause internal damage if left unchecked. Any unfamiliar noise from the engine bay warrants a professional inspection to prevent further harm. Decreased Power and Performance If you notice your vehicle struggling to accelerate, experiencing rough idling, or losing power while driving, it’s a sign of trouble. Common causes include clogged fuel injectors and ignition system problems. Even small changes in performance can indicate developing issues that will only worsen over time, so it’s best to have a mechanic evaluate the cause immediately. Discolored/Excessive Smoke from the Exhaust The color of your exhaust smoke can reveal a lot about your engine’s condition. Blue smoke suggests oil is burning, white smoke can indicate coolant leakage from a blown head gasket, and black smoke often points to an overly rich fuel mixture. Any of these conditions can lead to worsening engine issues if not corrected promptly. Fluid Leaks/ Burning Smells Puddles under your vehicle or the smell of burning oil or coolant are strong indications of a leak. Engine oil and coolant are vital for lubrication and temperature regulation, and low levels can quickly lead to overheating or internal wear. A mechanic can identify the source of the leak and repair it before it causes permanent damage.

Few issues are as alarming to drivers as seeing the temperature gauge climb into the red or noticing steam rising from under the hood. An overheating car can quickly escalate from a minor inconvenience to a major repair bill if not addressed promptly. At Murphy Family Auto Repair, we provide expert cooling system repair in the greater Mesa, AZ area. Here are four of the most common culprits behind this issue. Radiator Problems The radiator plays a central role in releasing heat from the coolant. If it becomes clogged with debris, or if the radiator fan fails, airflow is restricted and heat cannot dissipate effectively. A leaking radiator can also reduce coolant levels, compounding the problem. Radiator issues often lead to rapid overheating. Faulty Thermostat The thermostat regulates the flow of coolant between the engine and radiator. When working properly, it opens and closes to maintain the ideal operating temperature. If it gets stuck in the closed position, coolant cannot circulate, causing the engine to heat up quickly. A malfunctioning thermostat is a relatively inexpensive part to replace but can create significant overheating risks if ignored. Low Coolant Levels Coolant is the lifeblood of your vehicle’s cooling system, circulating through the engine and radiator to absorb and release heat. If your coolant levels are too low, your engine won’t be able to regulate its temperature properly. Water Pump Failure The water pump is responsible for circulating coolant throughout the engine. When it fails, coolant movement slows or stops, leading to dangerous spikes in temperature. Signs of a failing water pump can include leaks, grinding noises, or whining sounds. Because the water pump is so essential, its failure often leads to overheating in short order.

Your vehicle’s engine is a complex machine that relies heavily on clean, high-quality oil to function properly. While it may be tempting to put off an oil change when life gets busy, staying on top of this routine maintenance task is one of the most important things you can do to keep your car running smoothly. Ignoring your recommended oil change intervals can lead to decreased performance, costly repairs, and potentially even engine failure. At Murphy Family Auto Repair, we provide full-service oil changes in the greater Mesa, AZ area. Here are three reasons why you should always keep up with oil changes. Protects Your Engine Engine oil lubricates the moving parts inside your engine, reducing friction and preventing metal components from grinding against each other. Over time, oil breaks down and becomes contaminated with debris. When oil is old and dirty, it can no longer provide proper lubrication, leading to increased wear and tear on the engine. Regular oil changes help ensure your engine is protected with fresh, clean oil, which can significantly extend its lifespan. Improves Fuel-Efficiency When your engine runs smoothly and efficiently, it doesn’t have to work as hard, which can help improve fuel-economy. Dirty oil creates more resistance between internal components, making the engine work harder to perform even basic functions. Following your oil change schedule helps maintain your engine’s efficiency and can lead to noticeable savings at the gas pump over time. Prevents Costly Repairs Neglecting oil changes may save you money in the short term, but it often leads to much bigger expenses down the road. When engine oil becomes dirty, it can result in overheated components or lead to sludge buildup. These issues can cause significant internal damage, requiring extensive repairs. Sticking to a regular oil change schedule is a simple way to help prevent these problems and avoid unexpected expenses.

Your vehicle’s alternator plays a crucial role in keeping the electrical system running and the battery charged while the engine is on. Without a properly functioning alternator, your car can experience a range of issues that affect everything from your headlights to your ability to start the engine. Because alternator problems can lead to breakdowns or battery failure, it’s important to recognize the warning signs early. At Murphy Family Auto Repair, we provide expert alternator replacement and auto electric repair in the greater Mesa, AZ area. Here are four signs that your alternator may be malfunctioning and needs professional attention. Battery Warning Light on the Dashboard The battery warning light doesn’t only indicate problems with the battery itself—it often comes on when the alternator isn’t charging properly. This light usually appears as a battery symbol or the word ALT or GEN. Don’t ignore this warning, even if your car seems to be running normally at the moment. Dimming or Flickering Lights One of the more common symptoms of a bad alternator is dim or flickering lights. This includes your headlights, dashboard lights, and interior lighting. As the alternator begins to fail, it can’t maintain consistent voltage output, causing lights to lose brightness or pulse. If your lights seem unusually dim at night or flicker, it’s time to have your alternator tested. Strange Noises Coming from the Engine A failing alternator can produce unusual sounds such as grinding or whining. These noises often come from worn-out bearings or a loose belt connected to the alternator. Any unfamiliar noise coming from the engine area should be checked out to prevent more extensive damage. Electrical Accessories Working Erratically When the alternator begins to fail, it can’t supply consistent power to your vehicle’s electrical systems. You may notice issues such as power windows moving slowly, malfunctioning power seats, or a stereo that cuts out. These accessories rely on stable electrical power, and fluctuations in voltage can affect how well they operate.

Your vehicle’s suspension system does more than just keep your ride comfortable, it also helps maintain control and prevent rollovers. Ignoring suspension problems can lead to more serious damage and safety risks. Below, we discuss a few common warning signs to look out for. When you need suspension repair, including shock and strut replacement, bring your vehicle to Murphy Family Auto Repair in Mesa, AZ. Bumpy Ride? Something’s Off Unless you're off-roading, you shouldn’t feel every bump in the road. Struts and shock absorbers are designed to smooth out your drive. If your ride starts to feel rough or bouncy, it's a sign that these components may be worn. Depending on driving habits, shocks and struts typically need to be replaced every 50,000 to 100,000 miles. Steering Feels Off-Center? If your car pulls to one side or steering feels unusually difficult, even at low speeds, it could point to suspension trouble. A whining or screeching sound when turning may also signal low power steering fluid. If one side of the vehicle sits lower when parked and it's not part of the design, it may be time to inspect your springs, struts, and shocks. Uneven Tire Wear Uneven tread wear is more than a tire issue, it can also be a sign of failing suspension parts. Worn shocks, aging struts, or damaged components like ball joints, tie rods, and control arms can all lead to imbalanced wear and increase the risk of a tire blowout. A thorough suspension inspection should cover all these parts. Suspension Repair in Mesa At Murphy Family Auto Repair, our professional technicians offer suspension repair as well as shock and strut replacement for all makes and models. If your suspension seems off, head to our Mesa auto shop. We have plenty of experience working on domestic, European, and Asian-manufactured vehicles.

Changing your car’s filters might not seem like a big deal, but neglecting them can lead to major performance problems down the line. Filters keep dirt and debris out of important parts of your vehicle, helping it run smoothly. There are three main filters you should stay on top of: the oil filter, air filter, and fuel filter. When it’s time to replace your filters in Mesa, AZ, give the team at Murphy Family Auto Repair a call. Oil Filter Your engine oil does a lot of heavy lifting; it lubricates moving parts, reduces friction, and carries away heat. But as it flows through your engine, it can pick up tiny metal shavings and dirt. That’s where the oil filter comes in. It traps all that grime, so the oil stays clean and effective. A clogged oil filter, on the other hand, can’t do its job properly, leading to poor engine performance and even long-term damage. Swapping it out during your regular oil change is a simple step that pays off big. Air Filter Engines need clean air to perform well. The air filter keeps out dust, pollen, and debris from the air that enters the engine. In dusty environments or during allergy seasons, it can get clogged quickly. When that happens, your engine has to work harder to get the oxygen it needs, which hurts fuel efficiency and power. Replacing the air filter regularly helps your car “breathe” better and improves performance. Fuel Filter The fuel filter’s job is to stop dirt and rust from making their way into your engine through the fuel lines. Over time, this filter can get clogged, restricting the flow of fuel and causing your car to hesitate, stall, or even struggle to start. Regular replacement keeps your fuel system clean and your engine running efficiently. Car Tune-Up Services in Mesa When your vehicle starts getting poor fuel economy, misfires, has performance issues, or otherwise just doesn’t seem to be running right, it may be time for a car tune-up service. During an engine tune-up, your vehicle may undergo a variety of minor auto maintenance services, such as installing new spark plugs, replacing the air, oil, and fuel filter, or completing fuel injection cleaning. Give us a call at (480) 597-8097 to request an estimate for the cost of a tune-up for your car.

If your car has been slipping gears, refusing to shift, or making unsettling grinding noises, you might be facing one of the bigger repair jobs in the automotive world—a transmission replacement. While it sounds intimidating (and, let’s be honest, it’s not cheap), understanding what actually happens during the process can help ease the stress. If you suspect you need a transmission replacement in Mesa, AZ, give the team at Murphy Family Auto Repair a call. How Do Mechanics Know It’s Time to Replace the Transmission? Before jumping into a full replacement, our mechanics run a series of diagnostic tests. These might include scanning for error codes, checking fluid levels and conditions, and performing road tests to observe shifting performance. In some cases, a failing transmission can be repaired or rebuilt, but if there’s extensive damage, like burned-out clutches, warped gears, or contaminated internal components, then a full replacement is often the most reliable (and cost-effective) solution. Out With the Old, In With the New (or Rebuilt) Once a replacement is deemed necessary, the vehicle is lifted, and the transmission is carefully disconnected from the engine and drivetrain. This involves removing the driveshaft, unbolting the transmission from the engine block, and disconnecting the linkage, electrical connections, and cooler lines. It’s a labor-intensive job that requires precision. Depending on the situation, your mechanic may install a brand-new transmission, a factory-remanufactured unit, or a professionally rebuilt one. Each has its pros and cons in terms of cost and warranty coverage. Installation and Testing Once the new (or rebuilt) transmission is installed, the mechanic reconnects everything, refills the transmission fluid, and reprograms any electronic control modules if necessary. But the job isn’t done yet; extensive testing ensures the new transmission shifts smoothly, operates at the right temperature and communicates properly with your vehicle’s computer system. Transmission Repair and Replacement in Mesa At Murphy Family Auto Repair, our professional technicians offer automatic transmission repair, manual transmission repair, and CVT transmission repair for all makes and models. So if you notice grinding gears, hard shifting, delayed shifting, or a transmission fluid leak, head to our Mesa transmission shop. We can properly diagnose issues and let you know what the best course of action is. Whether your vehicle needs minor transmission service, clutch repair or adjustment, or a full transmission replacement, we do it all. Give us a call at (480) 597-8097 to request an estimate for transmission repair in Mesa.

When you turn the key (or push the start button) and your car hesitates to come to life, it’s not just a minor annoyance—it could be a sign of underlying problems. Hard start issues can stem from various causes, and understanding them can save you time, money, and the frustration of unexpected breakdowns. When you need auto repair in Mesa, AZ, give the team at Murphy Family Auto Repair a call. Battery and Electrical Woes One of the most common culprits behind a hard start is a weak or failing battery. Over time, batteries lose their charge, especially in extreme weather conditions. In cold weather, battery performance can drop significantly, making it harder for your engine to turn over. Similarly, corroded or loose battery terminals can hinder the electrical connection, reducing the power available to start your car. Regular battery maintenance—cleaning terminals and checking voltage levels—can often resolve these issues before they escalate. Fuel System Challenges Another potential cause lies within the fuel system. A clogged fuel filter can restrict the flow of gasoline, leaving the engine starved for fuel. Similarly, dirty or malfunctioning fuel injectors can prevent the proper atomization of fuel, leading to inefficient combustion. In these cases, routine maintenance and timely replacement of fuel system components are essential to keep your car running smoothly. Ignition System Issues Your car’s ignition system plays a major role in getting your engine started. Faulty spark plugs, worn-out ignition coils, or even a malfunctioning ignition switch can result in hard starting. If the spark needed to ignite the fuel isn’t strong or consistent, your engine might struggle to fire up. Regular inspection and replacement of spark plugs, as well as monitoring the overall condition of the ignition system, can help prevent these problems. Additional Factors Other factors that can contribute to hard start issues include problems with the starter motor or even air intake restrictions due to a clogged air filter. A malfunctioning sensor, such as the crankshaft or camshaft position sensor, can also cause your engine’s computer to misjudge the timing of fuel injection, resulting in a rough start. Auto Repair in Mesa When you need auto repair, turn to Murphy Family Auto Repair.

Keeping a fleet of vehicles running smoothly is no small feat. With constant mileage and heavy usage, even the most reliable trucks can develop issues if not properly maintained. Recognizing early warning signs and knowing some quick fixes can help you avoid costly downtime and ensure vehicles are always ready for the road. When you need to schedule fleet vehicle maintenance or repairs in Mesa, AZ, give the team at Murphy Family Auto Repair a call. Spotting the Early Warning Signs One of the first things to watch for is unusual noises. If you start hearing grinding, clunking, or squealing sounds from your vehicle, it could be a sign that components like brakes, suspension, or even the transmission are wearing out. Another red flag is a noticeable drop in performance. If a vehicle hesitates, struggles to accelerate, or exhibits reduced fuel efficiency, it might be time for a thorough check-up. Warning lights on the dashboard—like the check engine or ABS indicators—should never be ignored either. These signals are often the vehicle’s way of telling you that something isn’t quite right. Common Repairs and Quick Fixes Brake System Repairs Fleet vehicles face heavy braking demands. If you notice squeaky brakes or a soft pedal, it might indicate worn brake pads or air in the brake lines. A quick fix can often be as simple as replacing the pads and bleeding the brakes. Regular inspections can catch this before it escalates into a more serious problem. Tire Issues Tire wear is another frequent problem. Uneven tread wear, bulges, or low pressure are common indicators that it’s time to either balance, rotate, or replace your tires. Maintaining proper tire pressure is a quick fix that improves fuel efficiency and extends tire life. Fluid Leaks and Low Levels Whether it’s engine oil, transmission fluid, or coolant, leaks and low fluid levels can cause major problems if not addressed. A visual inspection for puddles under the vehicle can help identify leaks early. Often, a simple repair such as replacing a worn seal or topping off fluids can prevent further damage. Suspension and Steering Issues Worn-out shocks, struts, or misaligned wheels can lead to uncomfortable rides and increased wear on tires. If you notice excessive bouncing or drifting while driving, a quick visit to a mechanic for an alignment or suspension check can be all it takes to restore smooth performance. Fleet Vehicle Maintenance in Mesa Fleet vehicles tend to spend a lot of time on the road, meaning they’ll generally require maintenance more often than a daily driver. At Murphy Family Auto Repair, our team is equipped to handle the service needs of all types of fleets, such as light-duty work trucks, including diesel trucks powered by Cummins, Power Stroke, or Duramax diesel engines, rental cars, taxis, delivery vans, police cars, mail trucks, and other company vehicles.
