Frequently Asked Automotive Questions
Common symptoms, warning signs, and maintenance concerns we regularly see in New Hampshire vehicles.
Why is my check engine light on?
A check engine light can be triggered by many different issues ranging from loose gas caps and oxygen sensors to ignition problems, emissions faults, fuel delivery concerns, or drivability issues.
Proper diagnostics are important before replacing parts. Learn more about our diagnostic services.
Why are my brakes squealing?
Brake squealing may be caused by worn brake pads, brake dust, corrosion, moisture, rotor wear, or brake hardware concerns.
New Hampshire winter conditions can accelerate brake wear and corrosion. Learn more about our brake repair services.
Why does my steering wheel shake while driving?
Steering wheel vibration can be caused by tire balance problems, suspension wear, wheel bearings, steering components, or brake rotor issues.
Rough roads and potholes can also contribute to suspension and steering wear over time.
What does a bad wheel bearing sound like?
A failing wheel bearing often creates a humming, growling, grinding, or roaring sound that changes with vehicle speed or while turning.
Wheel bearing noise is commonly mistaken for tire noise. Suspension and wheel bearing concerns are especially common after harsh winters and rough road conditions.
Why does my battery keep dying?
Battery problems may be caused by old batteries, failing alternators, charging system faults, parasitic electrical drains, poor connections, or temperature extremes.
Learn more about alternator and electrical diagnostics.
Why is my car overheating?
Overheating may be caused by coolant leaks, radiator problems, water pumps, failed thermostats, cooling fan issues, or low coolant levels.
Learn more about cooling system repair.
How often should I change my oil?
Oil change intervals vary by vehicle, engine type, oil type, driving habits, and manufacturer recommendations.
Many modern vehicles typically require oil changes between 5,000 and 7,500 miles, though some vehicles may differ.
