5 Symptoms of a Brake Problem that You Shouldn’t Ignore

Interstate Automotive • November 19, 2024

Your vehicle’s braking system is crucial for safe driving, and when it begins to show signs of trouble, it's essential to address them quickly. Ignoring brake problems can lead to costly repairs, or worse, put you and others on the road at risk. At Interstate Automotive, we provide expert brake repair in the greater Olympia, WA area. Here are five common signs of a brake issue that mean it's time to visit the mechanic.

Squeaking or Squealing Noises

One of the first signs of a brake problem is a high-pitched squeaking or squealing noise when you apply the brakes. This is often caused by a worn-down brake pad, which includes a small metal indicator designed to create this noise as a warning.

Grinding Sounds

If you hear a grinding noise when you press the brake pedal, it’s typically a sign that your brake pads have completely worn away, and the metal parts of the brakes are now rubbing against each other. This not only reduces braking efficiency, but can also damage the rotors, leading to more costly repairs. Grinding sounds should be addressed immediately to prevent further damage.

Vibrations when Braking

When you press the brake pedal and feel a vibrating or shaking sensation, it often points to warped rotors. Warped rotors create an uneven surface, causing the brakes to pulse when you slow down. This vibration can affect your control over the vehicle, so having the rotors resurfaced or replaced will help ensure smooth and safe braking.

Soft or Spongy Brake Pedal

A soft or spongy brake pedal, one that sinks closer to the floor when pressed, can indicate an issue with the brake fluid or the brake lines. This can happen if air gets into the brake lines or if there’s a leak in the brake fluid system. Without sufficient fluid pressure, your brakes won’t be as effective. This is a serious safety concern and should be checked immediately by a professional.

Car Pulls to One Side When Braking

If your car pulls to one side when you apply the brakes, it may be due to a stuck caliper. A vehicle that doesn’t stop in a straight line can be difficult to control and increases your risk of an accident, making it important to address this issue ASAP.

What caused my check engine light to come on? Here are 5 common triggers

By Interstate Automotive • April 16, 2025

Seeing your check engine light illuminate on the dashboard can be alarming, but it doesn’t always mean your car is about to break down. The check engine light is designed to alert you to potential issues that range from minor to major. Addressing the problem early can prevent more costly repairs and keep your vehicle running smoothly. At Interstate Automotive, we provide expert check engine light diagnostics and repair in the greater Olympia area. Here are five of the most common reasons your check engine light may turn on. Faulty Oxygen Sensor Your car’s oxygen sensor monitors the level of unburned oxygen in the exhaust and helps regulate the air-fuel mixture. A failing oxygen sensor can lead to poor fuel-efficiency and increased emissions. Replacing a faulty oxygen sensor as soon as possible helps maintain fuel economy and engine performance. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the amount of air entering the engine and helps adjust fuel injection accordingly. A malfunctioning MAF sensor can cause poor acceleration, rough idling, and reduced fuel-efficiency. If the sensor fails, the car may even stall or have trouble starting. Worn or Failing Spark Plugs and Ignition Coils Spark plugs and ignition coils play a crucial role in igniting the fuel mixture in your engine. When these components wear out, your car may experience misfires, rough idling, or difficulty starting. Replacing spark plugs and ignition coils at the recommended intervals helps ensure smooth engine operation. Failing Catalytic Converter The catalytic converter reduces harmful emissions by converting pollutants into less toxic gases. A failing catalytic converter can lead to poor fuel-efficiency and reduced engine performance. With a bad catalytic converter, you might notice a smell similar to rotten eggs. Loose or Faulty Gas Cap One of the simplest and most overlooked reasons for a check engine light is a loose or faulty gas cap. The gas cap helps seal the fuel system. If it’s loose or missing, fuel might evaporate before your engine gets the chance to run on it.

Is my car leaking transmission fluid? Don’t ignore these 5 warning signs

By Interstate Automotive • March 22, 2025

Your vehicle’s transmission relies on fluid to keep its components lubricated and running smoothly. When a transmission fluid leak occurs, it can lead to serious mechanical issues, costly repairs, and even complete transmission failure if left unchecked. At Interstate Automotive, we provide expert transmission fluid leak repair in the greater Olympia, WA area. Here are five signs that your vehicle may be losing transmission fluid. Puddles of Red Fluid Under Your Car One of the most obvious signs of a transmission fluid leak is a puddle of red or brown fluid forming beneath your vehicle. Transmission fluid is typically bright red when fresh, but it can turn darker brown as it ages. If you notice an oily spot in your driveway or garage, it’s important to determine whether it’s transmission fluid or another type of automotive fluid. If you suspect a leak, have a professional inspect your vehicle to locate and repair the source of the problem. Difficulty Shifting Gears Low transmission fluid levels can lead to sluggish, rough, or delayed gear shifts. Transmission fluid plays a vital role in creating hydraulic pressure for smooth gear changes, so difficulty in shifting could be a warning sign of a possible leak. Burning Smell Coming from the Engine If you detect a strong burning odor while driving, it could be due to overheating transmission fluid. When fluid levels drop due to a leak, the remaining fluid may overheat as it struggles to keep the transmission cool and lubricated. If this issue is not addressed quickly, it can cause severe damage to the transmission. Unusual Noises While Driving A healthy transmission should operate smoothly and quietly. If you begin to hear whining or grinding sounds, it could be a sign that your transmission fluid is low due to a leak. These noises typically indicate that metal components within the transmission are not receiving adequate lubrication, leading to increased wear and tear. Transmission Slipping or Hesitation Transmission slipping occurs when the transmission fails to stay in the correct gear, causing a sudden loss of power or erratic shifting. This can be especially dangerous when driving at higher speeds or merging onto highways. When transmission fluid leaks, the hydraulic pressure needed for proper gear engagement diminishes, leading to slippage or hesitation.
