Common Signs of Engine Trouble We Can Fix at Our Novato Auto Shop

Novato Auto Service • October 26, 2023

At the first indication of an engine problem, you’ll want to be proactive about getting to the shop. Otherwise, the problem could soon escalate and cost a lot more to fix. At Novato Auto Service, we provide expert engine repair in the greater Novato, CA area. Here are five common signs of engine trouble.


Check Engine Light

If your check engine light flashes on, it doesn’t automatically mean that disaster is imminent. But you should still get to the shop for diagnostics so the issue can be identified and resolved before it gets worse. Common check engine light triggers include issues with catalytic converters, O2 sensors, MAF sensors, and spark plugs.


Strange Noises

Unusual noises coming from your engine should never be ignored. Common engine-related noises include knocking, tapping, hissing, and rattling. A knocking noise could indicate issues with the engine's connecting rods, while a hissing sound might be a sign of a vacuum leak. If you hear any unfamiliar sounds coming from under the hood, it's best to get it checked out ASAP. 


Decreased Power/Performance

Power loss can be caused by serious issues such as piston or head gasket trouble. Decreased performance may arise due to issues such as fuel system problems, clogged air filters, or worn-out spark plugs. Regular maintenance can help prevent these issues.


Overheating

Overheating can lead to severe engine damage, so it should be addressed promptly. Common causes of engine overheating include coolant leaks, a malfunctioning thermostat, or a failing water pump. If you see your temperature gauge climbing into the red zone, find a safe place to park. Then, turn off the engine and seek assistance.


Rough Idling

A healthy engine should run smoothly even at idle. If you experience a rough or shaky idle, it may be due to problems with the spark plugs, fuel injectors, or air intake system.

Few things are more frustrating than getting in your car, turning the key, and being met with either a sluggish engine start or complete silence. Hard-start and no-start issues can happen unexpectedly and are often symptoms of underlying problems that need immediate attention. At Novato Auto Service, our local mechanics are experts at diagnosing and fixing problems that cause no-start. Here are four common reasons your car might struggle to start—or fail to start altogether. Weak or Dead Battery A weak or dead battery is one of the most common causes of starting trouble. If the battery doesn’t have enough charge, it won’t be able to power the starter motor or ignition system. In some cases, you might hear a clicking noise when you try to start the car. Batteries naturally lose power over time, and extreme temperatures can accelerate the process. Corroded battery terminals or loose connections can also interfere with proper electrical flow, leading to starting problems. Failing Starter Motor The starter motor is responsible for cranking the engine when you turn the key. If it fails, the engine won’t turn over. A bad starter may produce a single click or no sound at all. Over time, the internal components of the starter motor can wear out. If your battery is fully charged but your car still won’t start, the starter motor could be to blame. Ignition Switch Problems The ignition switch sends power from the battery to various components, including the starter and fuel systems. When the ignition switch fails, your vehicle may not respond when you try to fire it up. A faulty ignition switch might also cause intermittent starting issues, making it more difficult to diagnose right away. Fuel Delivery Issues Your car needs the right amount of fuel to start and run properly. Problems with the fuel pump, fuel filter, or fuel injectors can prevent fuel from properly reaching the engine, resulting in a hard-start or no-start condition. A clogged fuel filter can restrict fuel flow, while a failing fuel pump may not supply enough pressure to start the engine.

The shocks in your vehicle play a critical role in ensuring a smooth and controlled ride by absorbing bumps and keeping the tires in contact with the road. As the miles add up, shocks wear out and lose their effectiveness, leading to a less comfortable ride and potential safety issues. At Novato Auto Service, we provide expert suspension repair in the greater Novato, CA area. Here’s a look at five signs that it’s time to replace your shocks. Bouncy or Rough Ride A common sign that your shocks are in need of replacement is a bouncy, rough, or uncomfortable ride. When shocks wear out, they can no longer absorb the impacts of road bumps effectively, leading to excessive bouncing. If you notice your car bouncing excessively after hitting a bump, it’s a strong sign that your shocks are past their prime. Longer Stopping Distances Shocks help keep your tires in contact with the road while braking. Worn shocks can cause your car to “nose-dive” or dip forward when you press the brake pedal, which increases stopping distances and can affect overall braking performance. If you’ve noticed that your car takes longer to come to a stop, it’s time to get your shocks checked. Uneven Tire Wear Shocks that are no longer functioning properly can lead to uneven tire wear. This happens because the shock absorbers fail to evenly distribute the weight of the vehicle, causing some tires to wear down faster than others. If you notice bald spots or uneven tread wear, it’s a good idea to inspect the shocks. This type of wear can shorten the lifespan of your tires and reduce overall vehicle safety. Leaking Fluid Shock absorbers are filled with fluid that helps them maintain their performance. If you notice fluid leaking from the shock absorbers, it’s a clear sign that the shocks are worn or damaged. Leaking shock fluid reduces the shock’s ability to function properly, leading to poor ride quality and handling. If you spot any fluid around the shocks, it’s time for a professional inspection. Unstable Handling or Poor Control If your car feels unstable or difficult to control, especially when turning or driving over rough terrain, it could be due to worn shocks. Shocks are essential for maintaining proper vehicle handling by keeping the tires in contact with the road. If your vehicle feels loose or harder to steer, it may be a sign that the shocks are no longer performing at their best and should be replaced.

A healthy transmission plays a critical role in enabling smooth operation and reliable performance. Without proper care, transmission problems can lead to costly repairs or even complete failure. To keep your transmission in excellent condition and extend its lifespan, consider these quick tips for keeping your transmission healthy. Check and Change Transmission Fluid Regularly Transmission fluid is vital for lubricating moving parts, cooling the system, and enabling smooth gear shifts. But as the miles add up, the fluid can become contaminated or lose its effectiveness, leading to increased wear and overheating. Regularly check the fluid level and condition using the dipstick, if your car has one, or follow manufacturer guidelines for inspections. Dirty or low transmission fluid should be addressed promptly, and a complete fluid change should be done in accordance with your vehicle's requirements. Avoid Overheating the Transmission Excessive heat is one of the leading causes of transmission damage. Driving in stop-and-go traffic, towing heavy loads, or driving aggressively can increase transmission temperatures, potentially causing the fluid to break down. To help prevent overheating, avoid overloading your vehicle. Use the Correct Type of Transmission Fluid Not all transmission fluids are the same, and using the wrong type can result in poor performance and internal damage. Always refer to your vehicle's owner manual or consult with the mechanic to ensure you use the recommended fluid. Be Gentle with Gear Changes Abrupt gear changes or improper shifting can put unnecessary stress on your transmission. For vehicles with manual transmissions, avoid riding the clutch or shifting gears roughly. In automatic vehicles, always come to a complete stop before switching from reverse to drive or vice versa. Driving habits that minimize strain on the transmission will help prevent wear. Schedule Regular Transmission Inspections Even if your transmission seems to be working fine, regular professional inspections are crucial to catching small problems before they escalate. The mechanic can check for leaks, worn parts, or unusual noises that might indicate a developing issue. Early detection and preventive maintenance can help save you from expensive repairs.

The check engine light is a sign that your vehicle’s onboard diagnostic system has detected an issue that needs attention. At Novato Auto Service, we provide expert check engine light diagnostics and repair in the greater Novato, CA area. Here’s a look at five common check engine light triggers. Faulty Oxygen Sensor The oxygen sensor plays a critical role in monitoring the balance of air and fuel in your engine. If the sensor becomes damaged or malfunctions, it can cause inaccurate readings, leading to reduced fuel-efficiency and increased emissions. A faulty oxygen sensor is one of the most frequent triggers for the check engine light and should be replaced as soon as possible to maintain optimal engine performance. Loose or Damaged Gas Cap It may seem surprising, but a loose or damaged gas cap is a common reason the check engine light comes on. The gas cap seals the fuel system, and if it isn’t tightly secured, fuel may evaporate before your engine gets the chance to use it. Failing Catalytic Converter The catalytic converter helps reduce harmful emissions by converting pollutants into less harmful gases. A failing catalytic converter can also lead to poor performance and increased emissions, making immediate attention important. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the amount of air entering the engine and helps regulate the air-to-fuel ratio. If the sensor fails, your engine may run too rich or too lean, leading to poor fuel-economy and potential engine stalling. Worn or Misfiring Spark Plugs Spark plugs are essential for igniting the fuel-air mixture in your engine’s cylinders. When spark plugs wear out or misfire, they can cause engine performance issues such as rough idling, reduced power, and poor fuel-efficiency. Worn spark plugs are a frequent reason for the check engine light and should be replaced as part of your vehicle’s regular maintenance.
