Engine issues often escalate quickly, making it important to get to the shop at the first sign of trouble. At Interstate Automotive, we provide expert engine repair in the greater Olympia area. Here’s a look at five warning signs that you need engine repair.


Check Engine Light Is On

One of the most common signs that your car needs engine repair is when the check engine light comes on. This light serves as an early warning system that something isn't right under the hood. While it doesn't necessarily mean there's currently a catastrophic issue, ignoring it could lead to more severe damage, so it's important to get your vehicle checked as soon as possible.


Strange Noises

If you start hearing unusual sounds coming from your engine, it's often a sign of trouble. Knocking, tapping, or grinding noises can indicate a variety of engine issues, including worn-out bearings or insufficient lubrication. These noises are a strong indication that your engine needs professional attention.


Discolored/Excessive Exhaust Smoke

The color and quantity of your car's exhaust smoke can give you valuable clues about your engine's health. Blue smoke indicates that oil is burning. White smoke suggests an internal coolant leak, and could mean you have a blown head gasket. Black smoke commonly points to the engine burning too much fuel. Any unusual exhaust smoke should be checked out by the mechanic right away.


Poor Performance and Reduced Power

If you notice that your car is struggling to accelerate, feels sluggish, or has lost its usual power, there could be an engine problem at play. Poor performance can result from a variety of issues, including fuel system and ignition system problems. Regardless of the cause, a drop in performance is a red flag that your engine needs attention.


Engine Stalling or Misfiring

Frequent engine stalling or misfiring can be a sign of a serious problem. These issues could be caused by faulty spark plugs or fuel delivery problems. If your engine stalls when you're driving or misfires regularly, it's crucial to get it inspected.

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.
