Your vehicle tells you when something's wrong, and it's important to listen. Proper alignment ensures even tire wear and smooth handling, while calibrated ADAS systems keep your safety features functioning as designed. If you've recently had windshield replacement, collision repairs, or suspension work in Fredericksberg, Woodbridge, and surrounding areas, your ADAS likely needs recalibration. Watch for these warning signs:

• Vehicle pulling to one side
• Uneven or rapid tire wear
• Steering wheel off-center when driving straight
• Dashboard warning lights for safety systems
• Lane departure warnings malfunctioning
• Adaptive cruise control not working properly

Ignoring these issues can compromise your safety and lead to costly repairs down the road. Our certified technicians have over 30 years of combined experience diagnosing and correcting these problems quickly.
