Your Lane Departure Warning System Just Went Silent After Windshield Service – Here’s Why Calibration Is Critical
You just had your windshield replaced and everything looks perfect – until you notice your lane departure warning system isn’t working properly. Warning lights flash on your dashboard, or worse, the safety features that help keep you between the lines have gone completely silent. This isn’t a coincidence, and it’s definitely not something you should ignore.
Replacing a windshield requires that the ADAS cameras and sensors be removed from the original windshield and reinstalled onto the new windshield, which can completely disrupt these critical safety systems. Understanding why calibration is necessary – and what happens when it’s skipped – could be the difference between safe driving and a serious accident.
Why Your Safety Systems Stop Working After Windshield Replacement
In many newer model vehicles with advanced driver assistance systems (ADAS) there are cameras, sensors and other equipment mounted on the windshield that can affect how your car functions. Your lane departure warning system relies on precise camera positioning to monitor lane markings and alert you when your vehicle drifts.
A change in camera angle of just one degree can have a huge impact on the camera’s viewing area, which can affect how the vehicle’s ADAS features will work. As AAA explains, “… a sensor on the car that is out of alignment by a fraction of an inch or even one degree will be aimed at an area significantly off axis 50 or more feet down the road.”
Even when technicians are extremely careful during windshield replacement, many forward-facing ADAS cameras are mounted directly on or near the windshield. Even the slightest change in their position, caused by removing or installing a new windshield, can throw off alignment.
The Hidden Dangers of Skipping Calibration
Without calibration, the vehicle’s ADAS features may not function properly, which can lead to an accident. The consequences extend far beyond inconvenience:
- False confidence: You might think your safety systems are protecting you when they’re actually providing inaccurate information
- Delayed warnings: According to IIHS Advisory 43, a change as little as .6 degrees would cut the reaction time of AEB in half
- Complete system failure: Neglecting recalibration can also lead to inaccurate readings, false warnings, or even the complete failure of the ADAS systems
Real-world examples highlight these risks. A coworker had his replaced on the cheap and his cruise control with lane follow stopped working, demonstrating how improper service can disable multiple safety features simultaneously.
Which Systems Need Recalibration
Several ADAS systems may require recalibration after windshield replacement or repair. These include: LDW systems use cameras to monitor the vehicle’s position within the lane. Beyond lane departure warning, other affected systems include:
- Forward Collision Warning (FCW): FCW systems use radar sensors to detect potential collisions with objects or vehicles ahead. Recalibration ensures the radar sensor is accurately aligned and calibrated to provide timely warnings
- Automatic Emergency Braking (AEB): AEB systems use various sensors to detect imminent collisions and automatically apply the brakes if necessary. Recalibration ensures the sensors are accurately aligned to provide timely and reliable braking assistance
- Adaptive Cruise Control: ACC systems use radar or laser sensors to maintain a safe distance from the vehicle ahead. Recalibration ensures the sensors accurately measure the distance and adjust the vehicle’s speed accordingly
The Professional Calibration Process
Even though it sounds simple, calibration is a complex process that requires special equipment and training. The technicians at Auto One are experienced with ADAS calibration using tools like the Opti-Aim™ or the Autel MaxiSys.
The calibration process adjusts and tests all the cameras and sensors on the windshield to ensure they are still working properly after it is replaced. Professional calibration typically involves:
- Diagnostic assessment of all ADAS components
- Use of manufacturer-specific calibration equipment
- Verification of proper system functioning
- Documentation of completed calibration work

Cost Considerations and Insurance Coverage
ADAS recalibration costs vary depending on several factors, including your vehicle’s make, model, and year, the number and type of systems requiring recalibration, the method of recalibration needed (static vs. dynamic), and your location.
The good news is that in many cases, insurance policies cover windshield recalibration as part of windshield replacement or repair. As long as you have comprehensive coverage you’ll only be responsible for paying your deductible, and the other recalibration costs will be covered. We partner with hundreds of insurance companies and will even verify your coverage and file your claim so you can stress less.
Don’t Risk Your Safety
While it may be possible to drive your vehicle without immediate recalibration, it is highly recommended to have the recalibration performed as soon as possible after windshield replacement or repair. Without recalibration, the ADAS systems may not function correctly, potentially compromising the safety features designed to assist and protect you while driving.
It is 100% necessary for drivers to recalibrate their ADAS after replacing their windshield. Your lane departure warning system and other safety features are designed to protect you and your passengers – but only when they’re working correctly. Don’t let a simple calibration oversight put your family at risk on Texas roads.
When your windshield needs replacement, make sure your service provider has the proper equipment and expertise to restore your safety systems to factory specifications. Your life may depend on it.
