If you open your trunk and find the carpet soaked after a rainy day, that’s more than just an inconvenience—it’s a sign that water is getting into your car where it shouldn’t be. A wet trunk doesn’t just ruin whatever you’re storing back there. Over time, it can lead to mold, mildew, and corrosion that damages your vehicle’s structure and electrical components. Water intrusion in the trunk area is surprisingly common, especially in older vehicles or those that have been through body repairs. The good news is that most leaks can be tracked down and fixed without major work—if you know where to look.    Where the Water Is Coming From One of the most common sources of trunk leaks is a worn or damaged trunk seal. This rubber gasket surrounds the edge of the trunk and is designed to keep water out, but age, heat, and pressure can cause it to crack, flatten, or come loose. Another culprit? Tail light assembli ... read more

Spark plugs may be small, but they have a big impact on engine performance. They create the spark that ignites the air-fuel mixture, powering your vehicle. Over time, worn-out spark plugs can lead to rough idling, poor fuel efficiency, sluggish acceleration, and even difficulty starting your car. Replacing them at the right time can prevent engine problems and keep your vehicle running at its best.    What Do Spark Plugs Do Each time you start your car, the spark plugs generate a high-voltage spark to ignite the fuel inside the combustion chamber. This controlled explosion powers the engine, creating the energy needed to move your car. A properly functioning spark plug ensures efficient fuel combustion, smooth engine performance, and optimal fuel economy.    Signs Your Spark Plugs Need to Be Replaced While spark plugs can last anywhere from 30,000 to 100,000 miles, depending on the type and manufacturer recommendations ... read more

Ever notice your car pulling to one side or a weird vibration in the steering wheel? These could be signs your wheels are out of alignment. But how does this happen? Wheel alignment issues don’t just come out of nowhere; they’re caused by everyday wear and tear or specific incidents that knock things out of place. Misaligned wheels can lead to uneven tire wear, poor handling, and even safety risks, so understanding the causes is important.    Everyday Driving Hazards The roads we drive on aren’t perfect. Potholes, curbs, and rough patches are all too common and can wreak havoc on your car’s alignment. Hitting a pothole at high speed can jolt the suspension system, shifting the angles of the wheels. It might not seem like a big deal at first, but even a small misalignment can worsen over time. Similarly, accidentally bumping into curbs while parking or making sharp turns can nudge the wheels out of place. Even driving over spee ... read more

Buying a car is a significant decision. With so many choices and variables to consider, it’s easy to get caught up in the excitement of purchasing your dream vehicle. However, there’s one step you shouldn’t overlook—a pre-purchase inspection. This simple but thorough examination can save you from potential headaches and financial loss in the future. But why is a pre-purchase inspection a smart investment?    What Is a Pre-Purchase Inspection A pre-purchase inspection (PPI) is a comprehensive check performed by a professional technician to assess the condition of a vehicle before the purchase is finalized. The technician will carefully examine all the key components, including the engine, transmission, brakes, suspension, and electrical systems, as well as the exterior and interior condition of the car. This inspection helps identify any underlying issues or future repair needs that might not be visible during a casual test drive ... read more
