What to Do When a Triangle Exclamation Mark Appears in the Car?
2 Answers
Solutions for a triangle exclamation mark appearing in the car: 1. Check if all the bulbs in the vehicle are functioning properly, with a focus on the brake lights and license plate lights. If any bulb is damaged, replace it. 2. If the bulbs are intact and functioning normally, inspect the wiring harness in the trunk for any damage. If found, wrapping it with tape can resolve the issue. Note that if the car's headlights have been modified, this problem may also occur. Additionally, some car models display this symbol to remind the owner that the vehicle requires maintenance, and it will disappear after servicing. Other issues such as parking sensor failure, overheating of the dry dual-clutch transmission, or warnings/failures in the traction control system may also trigger this indicator light.
I also encountered this triangle exclamation mark while driving last week and was so startled that I immediately pulled over. After checking the manual, I found out it represents a general warning, which could indicate low tire pressure, a broken brake light, or a minor system issue. I got out to inspect the tires but found nothing unusual. After restarting the car, the light was still on, so I hurried to the repair shop. The mechanic used a computer to diagnose the issue and found that the right rear brake light was out. Replacing the bulb fixed the problem. My advice is to first check basic items like tire pressure and lights. Don’t push through on a long trip—getting it checked early is the easiest solution.
