Follow the intervals in your owner’s manual and your vehicle’s maintenance minder. As a rule of thumb, plan for oil changes every 5,000–7,500 miles (synthetic), tire rotations every 6,000–8,000 miles, brake inspections every service, and fluids/filters at manufacturer intervals. Powerhouse Automotive can create a maintenance plan based on your mileage and driving conditions.
A check engine light indicates the powertrain control module detected a fault. It could be minor (loose gas cap) or more serious (misfire, emissions, sensor failure). If it’s flashing, avoid driving and call us. We’ll scan diagnostic codes, test underlying systems, and provide an estimate before any work begins.
Many modern engines require synthetic oil for protection and longer intervals. We follow manufacturer specs for viscosity and oil type. If you’re unsure, we’ll recommend the right oil based on your engine, mileage, and driving habits.
Squeaking can be caused by wear indicators, glazing, or debris; pulsation often points to rotor thickness variation or runout. We’ll measure pad thickness, rotor condition, and hydraulic performance, then recommend the right fix—pads/rotors, hardware, fluid service, or caliper work if needed.
