The alternator generates electrical power as your car moves. This power is used to maintain your battery at full charge and also to supply all the electrical power your car's electronic components demand. An alternator does last for many years, but it will eventually fail and will need to be replaced. In Fort Smith, AR, your Hyundai dealer can replace it for you. These are some of the signs that you may need an alternator repair.

Battery Warning Light

The battery warning light is often believed to signal a problem with the battery, but it means that there is a problem with the electrical system. The alternator is designed to work at a specific voltage, which is usually 13-14.5 volts. When an alternator starts to fail, its voltage will drop and this can cause the warning light to come on. The warning light may also start to flick on and off if your alternator is weakening. This is because the demands by the electrical components, for example, the windshield wipers, are constant but the alternator is not able to supply enough power. If the warning light comes on or flickers, we recommend bringing your car to our service department ASAP so we can investigate.

Burning Rubber or Metal Smells

Both of these smells are nasty, but they also represent problems with your alternator. The alternator is driven by a long belt called the serpentine belt that runs through several pulleys. The belt moves at great speed under constant tension and friction in a hot environment, and this can cause wear. A worn belt will give off the smell of burnt rubber. A worn alternator or damaged wires produce a smell of burning metal. Frayed or damaged wires create resistance to electricity, and as the alternator tries to supply power through them, they heat up and being to smell.

Stalling or Starting Problems

Stalling can be extremely dangerous, especially if it happens when you are traveling fast or overtaking another vehicle. The alternator supplies power to the spark plugs and coils for combustion to take place, which allows your car to move. If the alternator fails, and cannot supply enough power, your car may suddenly stall and just stop dead. A problem starting your engine can be caused by a weak alternator. If the alternator is weak and cannot charge the battery, your battery power may drop too low to start the ignition. If you hear a clicking sound when you try and start your engine, a damaged alternator is one of the likely culprits. The good news about a failing alternator is that it will never just fail. There are always warning signs that it is weakening. Now you know some of the signs, if you experience any of them call us right away at Crain Hyundai of Fort Smith. Our highly-trained technicians will be happy to check your alternator and replace it if needed. Image via Hyundai.

Ask the Hyundai Dealer: 4 Common Signs of a Faulty Ignition Coil

The ignition coil, an essential component in your Hyundai's ignition system, is responsible for transforming low voltage from the battery into high voltage required to generate a spark for igniting the air-fuel mixture in the combustion chamber. Visiting a Hyundai dealer for diagnosis and repairs is crucial as they have specialized knowledge, ensuring accurate identification of the faulty ignition coil and reliable repairs tailored specifically to your vehicle. 1. A Loss of Power If you notice a significant loss of power in your vehicle, it could be a sign of a defective ignition coil. When the coil is faulty, it may fail to deliver a strong spark, resulting in poor engine performance. You may experience sluggish acceleration, difficulty climbing hills, or a general lack of power. If you start to experience these symptoms, it's best to have your ignition coil checked by a qualified mechanic to regain optimal engine function. 2. Your Check Engine Light Is On One of the common indicators of a defective ignition coil is the illumination of the check engine light on your dashboard. The check engine light serves as a warning system that detects various issues with your vehicle's components, including the ignition system. When the ignition coil is malfunctioning, it can trigger the check engine light. Ignoring this warning can lead to further engine damage or decreased fuel efficiency. It's important to have your vehicle's diagnostic system scanned to retrieve error codes and pinpoint the specific issue. A professional mechanic can then diagnose the problem and recommend the necessary repairs to resolve the ignition coil issue. 3. Your Fuel Economy Decreases A damaged ignition coil can contribute to poor fuel economy in your vehicle. When the coil is faulty, it can lead to incomplete combustion or misfires, resulting in inefficient fuel consumption. You may notice that you are visiting the gas station more frequently than usual and that your vehicle's fuel efficiency has significantly decreased. 4. Misfiring Engine When an engine misfires, it means that one or more cylinders fail to ignite the air-fuel mixture properly. This can result in a rough-running engine, noticeable vibrations, and a lack of smooth power delivery. A damaged ignition coil can cause inconsistent or weak sparks, leading to misfires. If you experience frequent engine misfires, it's crucial to have your ignition coil checked. Ignoring this issue can lead to further damage to the engine components, such as the spark plugs or catalytic converter. Potential causes of a defective ignition coil include electrical faults, wear and tear over time, exposure to extreme temperatures, or moisture intrusion, which can all lead to compromised performance and eventual failure. If you've experienced any of the above-named issues, don't hesitate to reach out to us. Send us a message at Crain Hyundai of Fort Smith to book your diagnostic appointment with our experienced team.

Signs You Need New Spark Plugs From Your Hyundai Dealer

A vital component in your vehicle's engine system is the spark plug, and detecting early signs that your Hyundai needs new spark plugs can enhance performance, save you on fuel consumption, and prevent more serious problems down the road. Talk to a Hyundai dealer if you notice any of the following signs. Decreased Fuel Efficiency One of the first telltale signs that your Hyundai might require new plugs is a decrease in fuel efficiency. These plugs play an instrumental role in combusting the fuel in your engine, so if they are malfunctioning, your car may consume more fuel than necessary. If you notice you're visiting the gas station more frequently, it's time to consider having your plugs checked. Difficulty Starting the Vehicle These plugs are key to starting your Hyundai. They ignite the air-fuel mixture in the engine's combustion chamber, enabling your vehicle to start. If your Hyundai struggles to start, or you're experiencing more instances of your car failing to turn over, it may be a sign that your plugs need replacement. Poor Acceleration and Rough Idling The state of your plugs can impact your Hyundai's overall performance. If you're experiencing sluggish acceleration or your vehicle seems less responsive when you hit the gas pedal, it may be due to worn plugs. Additionally, a rough idle – where your Hyundai feels shaky and produces a loud, irregular noise while stationary – can also point to spark plug issues. Misfires and Engine Surges Finally, engine misfires or surges are significant indicators of spark plug failure. If your engine is not running smoothly or if it surges and falls repeatedly, it can be due to malfunctioning plugs. This erratic operation can lead to larger issues if not addressed promptly. How a Spark Plug Works A spark plug sends an electrical signal sent from the ignition coil, creating a spark that ignites the air-fuel mixture in the combustion chamber. This is what powers your engine and propels your vehicle forward. The electrodes on a spark plug are subjected to extreme conditions, and over time, they wear out. This deterioration is what leads to many of the symptoms previously described, such as decreased fuel efficiency, difficulty starting, poor acceleration, rough idling, and engine misfires or surges. At Crain Hyundai of Fort Smith, we understand the importance of proactive maintenance, and our team of experienced technicians is ready to help. If you suspect your Hyundai needs new plugs, don't wait until your vehicle's performance suffers. Reach out to Crain Hyundai of Fort Smith today and let's ensure your Hyundai continues to deliver the performance and efficiency you've come to expect.

3 Electrical Problems You Should Always Fix at Your Hyundai Dealer

Electrical problems can vary from minor to major, but they all affect your ability to enjoy the benefits of your Hyundai. If a problem isn't repaired, it could lead to extensive damage to your car. Fortunately, your Hyundai dealer in Fort Smith, AR, can fix any possible problem for you. These are a few potential issues that mean you need to visit us for a repair. Worn Alternator The alternator is a small generator inside your engine that produces electricity for your car's systems and devices while your engine is running. Some of the electricity it produces is used to recharge your battery. An alternator has an average lifespan of eight years before it needs replacement. Eventually, the alternator will slow down due to age wear, and this reduces the amount of power it produces. A failing alternator isn't usually noticeable when it starts, as the alternator produces more power than your car's systems require. As time passes, the reduced power supply from the alternator will cause problems for your car including misfiring, slower starting, and dim lights. The battery warning light on your dash will also illuminate. We can test your alternator and install a new one very quickly if required. Damaged Fuse Box Every electrical system in your car has a fuse. These fuses function identically to the ones in your home, as they protect their connected systems against electrical overloads and shorts. Fuses age and wear out, and they can also blow due to electrical shorts. The blown fuse prevents a short from damaging its system but also cuts power to that system until the fuse is replaced. If you're experiencing multiple blown fuses, the problem is very likely due to a damaged fuse box. Our technicians will test the fuse box and the wiring connected to it to find and isolate the problem. We can replace damaged wiring and fuses and will also install a new fuse box if it is causing the problem. Once the fuses are reconnected, your car's electrical system will work correctly again. Damaged Spark Plugs Healthy spark plugs are essential for efficient combustion, as they provide the ignition source for the fuel-air mixture in the cylinders. The spark plugs are supplied with power from the electrical system. Spark plugs will wear out in time, and we test and replace them as part of your car's service schedule. Plugs can also be damaged by the failure of other engine components, like a worn ignition coil or a fuel-rich engine. Damaged plugs will cause misfiring and could prevent your engine from starting. Our technicians will test each spark plug and replace any damaged ones. Problems in the electrical system can cause additional damage to your car and its systems.
