A check engine light could signal anything from a minor issue to a major repair. While auto parts stores can provide Diagnostic Trouble Codes (DTCs), these only point to the problem area, not the exact cause. At 21 Machine, we use advanced diagnostic tools to pinpoint the exact issue and recommend the right fix, saving you time and money. Don’t guess—let us handle it for you.

Regular tire checks are essential for safety. Replace your tires if you notice: Worn-out tread or bald spots. Cracks or bulges in the sidewalls. Uneven wear patterns or vibrations while driving. Embedded nails or objects. We can inspect, repair, or replace your tires and ensure proper tire balancing and alignment to keep you safe on the road.

If your car shows these signs, it’s time for an alignment: Pulling to one side while driving. Uneven tire wear. Vibrations in the steering wheel. Steering wheel not centered when driving straight. Proper alignment improves tire life, fuel efficiency, and ride quality. Schedule your alignment check with us today!
