What to Do If the ETC Keeps Falling Off?

You can use 3M double-sided tape for adhesion. If the device falls off, you can reactivate it and then reattach it using 3M double-sided tape. Here are some precautions for installing ETC: 1. Installation height: Pay attention to the height, which should not be lower than 1.2 meters or higher than 2.5 meters. 2. Installation angle: The installation angle N should be between 30° and 90°, which is the angle between the surface of the electronic tag and the horizontal plane. 3. Avoid obstruction: During installation, avoid the black areas on the windshield and do not install it in a position that blocks the solar battery. 4. Do not remove it arbitrarily after installation: Avoid ETC failure after removal.

I also encountered this issue before, where the ETC device kept falling off, which was really annoying. I remember when I first installed it, I didn’t clean the windshield thoroughly, and there were oil films and dust on it, so the adhesive couldn’t hold firmly. Later, I bought some alcohol and a cleaning cloth, wiped the glass repeatedly until it was clean, and then used stronger 3M double-sided tape to reattach it. When installing, make sure to choose a flat spot and avoid placing it too close to the edges. If the tape is old, replace it with new ones, as temperature fluctuations can degrade the adhesive. Keep checking and cleaning it, and after half a year, it became firmly fixed and stopped falling off. Before driving, take a quick look to avoid last-minute panic on the highway. This experience has helped many of my friends—just spend a little time on DIY to solve this small issue.

As someone who often helps others with car repairs, dealing with an ETC that won't stick requires a step-by-step approach. First, check if the mounting surface is clean and flat. If there's grease, wipe it with alcohol. If the tape is aged, replace it with new 3M tape or specialized adhesive—don't skimp on this cost. Choose a spot in the middle of the windshield, avoiding areas with high curvature. Try reattaching it and then use a hairdryer to heat and reinforce the bond. If it fails repeatedly, the device base might be damaged—it's best to visit an ETC service center for a replacement rather than forcing it. Avoid spraying chemicals on the glass daily to keep it dry. Addressing simple issues can prevent bigger troubles and ensure smooth passage.

Easy fix for ETC device constantly falling off. First, clean the windshield surface thoroughly to remove dust and grease. Then replace with strong adhesive tape like 3M brand for firmer attachment. Choose a flat area on the windshield and press firmly for several seconds. Avoid installation during large temperature variations as adhesive may fail. If it falls off temporarily, secure with rubber bands without obstructing vision, but reattach promptly. For frequent issues, visit a professional shop to avoid toll gate problems. Regular simple maintenance won't affect driving.

This is a common issue with known causes. Having driven for years, my ETC often wouldn't stick due to oily windshield film or aged adhesive tape. For thorough cleaning, use alcohol to wipe the surface clean, let it dry completely, then apply new high-strength adhesive tape. The placement must be on a flat area; reinstalling in a hot garage yields better results. If the device base becomes loose, it's time to replace it—don't try to save money here. Prevention involves cleaning the windshield quarterly to prevent dirt buildup. These small actions keep the device secure and hassle-free.

A fallen ETC device not only affects passage but also easily causes delays, so it's important to address it properly. Check if the installation spot is clean and dust-free, then use specialized double-sided tape like 3M products to stick it firmly. Choose a flat area on the windshield to avoid thermal shock weakening the adhesive. After reattaching, let it sit for half a day without driving. Frequent falling may indicate poor-quality tape—replace it promptly or visit a service center for recalibration. Develop a daily habit of checking before driving to ensure it's securely attached, guaranteeing safe passage and preventing minor issues from becoming major hazards.
