Why Your Lane Assist Isn’t Working After a Windshield Replacement

Posted on April 15, 2025

Advanced safety features like lane assist are becoming standard in modern vehicles, helping drivers stay safe and focused on the road. But if you’ve recently had your windshield replaced and noticed your lane assist isn’t working properly, you’re not alone. This issue is typically caused by a disruption to your vehicle’s ADAS (Advanced Driver Assistance Systems) and highlights the critical importance of ADAS calibration services. If you need professional service, Modern Automotive provides high-quality help you can rely on.

Getting to Know Lane Assist and ADAS Technology

Lane assist is one of your car's advanced driver aid systems, utilizing cameras and sensors that are usually fitted near or on the windshield to find lane lines and help maintain your vehicle in position. ADAS systems are extremely finely tuned and rely on precise angles and positioning in order to work. Even minimal misalignment in the windshield or its location will offset the accuracy of the system.

How Windshield Replacement Impacts Lane Assist

When your windshield is replaced or damaged, the mounted ADAS camera can be slightly displaced or misaligned; even if it's only a tiny misalignment, it causes the lane assist system to fail or shut down altogether. That's why ADAS calibration services are not an option, they're a necessity following windshield replacement.

Drivers expect that a standard auto glass replacement ensures their car is back to as-new condition, but by failing to recalibrate the ADAS, essential features like lane assist may be compromised. That is why it is important to work with an auto body shop in Vaughan that offers complete calibration services and windshield repair, such as Modern Automotive.

The Importance of Recalibration During Replacement

Recalibrating your car's ADAS involves resetting the system's sensors and cameras so that they are calibrated to factory specifications. There are two main types:

Static (performed in-shop with professional equipment)
Dynamic (performed while driving)

Most newer vehicles require both.

Modern Automotive offers accurate ADAS calibration services with the latest diagnostic equipment to get your systems optimally realigned. Without recalibration, your safety systems can issue false alerts or fail when you need them the most.

Signs Your Lane Assist Needs Calibration

If your dashboard indicates a lane assist warning light, or if the system is slow to react—or won't activate at all—your ADAS likely requires maintenance. Erratic lane keeping, excessive warning chimes, or clear drifting are all signs the system isn't calibrated correctly. A trip to a qualified auto body shop in Vaughan, like Modern Automotive, can quickly diagnose and fix the issue.

What to Do If Your Lane Assist Isn't Working

If your lane assist system stopped functioning after having your windshield replaced, call the location where the service was performed. Ask if they had an ADAS recalibration performed. If they did not, contact us at Modern Automotive and get your vehicle's safety systems in full operation in no time.
