Don’t Ignore these 5 Common Symptoms of an Engine Problem

February 27, 2025

Recognizing early warning signs of engine trouble can help you address problems before they become severe. By paying attention to how your vehicle behaves, you can help prevent breakdowns and extend the life of your engine. At American Five Star Auto Repair & Transmission, we provide expert engine repair in the greater Tempe, AZ area. Here are five common signs of an engine issue.

Strange Noises Coming from the Engine

Unusual sounds such as knocking, tapping, or grinding can indicate serious engine problems. A knocking noise could be a sign of worn-out bearings. Tapping noises may signal low oil levels. Grinding sounds might indicate a problem with the water pump or alternator. Any persistent or loud noise should be inspected by the mechanic to help prevent more serious damage.

Loss of Power/Poor Performance

If your vehicle loses power while driving or feels sluggish, you’ve got a sign of an issue with the engine. Reduced performance can be caused by problems such as clogged fuel injectors, a failing mass airflow sensor, or worn-out spark plugs. If your car is not responding as it normally would, it’s best to have it checked to avoid further complications.

Discolored/Excessive Smoke from the Exhaust

The color of the smoke coming from your exhaust can tell you a lot about potential engine problems. Blue smoke indicates that oil is burning. White smoke suggests coolant is leaking into the combustion chamber, which may be due to a blown head gasket. Black smoke signals that the engine is burning too much fuel. If you notice discolored/excessive smoke coming from your exhaust, it’s essential to diagnose and fix the problem quickly.

High Engine Temperature

If your temperature gauge rises above normal levels, it’s an indication that your engine is overheating. Overheating can be caused by failing cooling system components, such as a malfunctioning thermostat, a leaking radiator, or a broken water pump. Driving with an overheated engine can lead to severe damage. 

Check Engine Light 

The check engine light is a clear indication that something is wrong with your engine. While it could be triggered by a minor issue like a loose gas cap, it can also signal more serious problems, such as a failing oxygen sensor, catalytic converter trouble, or ignition system failure. Ignoring the check engine light can lead to bigger and more expensive repairs, so it’s best to visit the shop for diagnostics ASAP.

Why Do Car Batteries Die Faster in Arizona? | American Five Star Auto Repair & Transmission
September 26, 2025
If you live in Arizona, you’ve probably noticed that car batteries don’t seem to last as long as they do in other parts of the country. While most drivers elsewhere can expect three to five years from a battery, it’s common for Arizona batteries to give out in as little as two years. The intense desert heat plays a significant role, but several other factors also contribute. Knowing why this happens can help you take better care of your battery and avoid unexpected breakdowns. How Heat Affects Car Batteries Most drivers think cold weather is what drains a car battery, but extreme heat can actually be far more damaging. Inside your battery, chemical reactions produce the energy needed to start your car and power electrical systems. High temperatures speed up those reactions, which sounds like a good thing at first. The downside is that the heat also causes the battery’s internal components to wear out faster. Excessive heat evaporates battery fluid, which reduces its ability to hold a charge. It can also damage the plates inside the battery, making it harder for the battery to deliver power when you need it. Even though your car might start just fine for a while, the battery’s overall lifespan is being shortened every time it’s exposed to extreme heat. Under-the-Hood Temperatures Make Things Worse The Arizona sun is intense, but the heat doesn’t stop there. Under your hood, temperatures can climb well above 200 degrees, especially during summer driving. These conditions place additional stress on the battery and other components around it. If you’ve ever opened your hood after a long drive in the heat, you’ve experienced just how extreme these temperatures can get. Drivers who make frequent short trips are especially vulnerable. Every time the engine heats up and cools back down, the battery endures repeated thermal cycles, which accelerates internal wear. Heavy Electrical Demand Modern vehicles rely on far more electronics than older models. Between air conditioning systems running at full blast, infotainment units, power-hungry sensors, and driver-assist features, today’s batteries have a lot more work to do. In Arizona, where air conditioning often runs nonstop for months, the demand on the battery is even greater. If your alternator or charging system isn’t keeping up, the battery can’t fully recharge between trips. Over time, this constant strain shortens its lifespan, especially in the intense desert heat. The Role of Driving Habits Short trips and stop-and-go driving are common in city areas and contribute to battery wear. When you only drive a few miles at a time, the alternator doesn’t have enough time to fully recharge the battery. Combine that with the heat, and you have a recipe for frequent battery replacements. Longer drives at steady speeds allow the alternator to restore more energy to the battery. If most of your driving is around town, consider taking your car for a longer drive every so often to give the charging system a chance to catch up. How to Extend Your Battery’s Life While you can’t control Arizona’s climate, you can take steps to protect your battery and get as much life out of it as possible: Park in the shade or a garage whenever you can to reduce exposure to direct sunlight. Inspect and clean battery terminals regularly to prevent corrosion that interferes with charging. Check fluid levels if you have a serviceable battery, since heat accelerates evaporation. Test your battery often, especially before summer, to catch early signs of weakness. Have the charging system inspected during routine maintenance to ensure it’s keeping up with demand. These simple habits won’t make your battery immune to Arizona’s climate, but they can give you more time before a replacement is necessary. Signs Your Battery Is Failing Slow or hesitant engine starts. Flickering dashboard lights or dim headlights. Frequent need to jump-start the car. Warning lights related to the charging system. If you notice these symptoms, it’s best to have the battery tested as soon as possible. Waiting until it fails completely can leave you stranded, especially in extreme heat when roadside assistance may take longer to arrive. Keep Your Car Ready for Arizona Roads with American Five Star Auto Repair & Transmission At American Five Star Auto Repair & Transmission , we understand how Arizona’s heat affects your vehicle. Our technicians can test your battery, inspect the charging system, and help you stay ahead of problems before they cause a breakdown.
