How to Deal with LDA Malfunction?

Send it to the nearest repair shop for maintenance. Here is more extended information about LDA: 1. Meaning: LDA malfunction refers to the loss of the lane departure warning function. LDA is the Lane Departure Alert system. When the vehicle deviates from the driving lane, the car will emit a beeping warning sound, and the steering wheel will slightly vibrate to remind the driver to pay attention to safe driving. 2. Function: The existence of the LDA function can help drivers correct the habit of not using turn signals when changing lanes. When LDA is turned on and the driver changes lanes without using the turn signal, the steering wheel will provide assistance to correct the direction and stay in the current lane to avoid sudden lane changes that may inconvenience vehicles behind.

Last month, my car suddenly displayed an LDA fault warning while I was on the highway, which made me extremely nervous. I first gradually slowed down and pulled over to the emergency lane. After turning off and restarting the engine, the warning was still there. Later, I checked the camera on the windshield and noticed some small insects and dust, so I gently cleaned it with a wet wipe. After restarting, the fault disappeared. However, just to be safe, I went to a repair shop where they used a computer diagnostic tool and found that the sensor interface was loose. After reinforcing it, the system returned to normal. My advice is to first clean the camera area when encountering such issues—most of the time, this will resolve the problem. If not, it's best to seek professional inspection. Don’t rely too much on the assist systems when a fault occurs; maintaining manual control of the steering is safer.
