If nothing else is working, try this...strangely it worked (from a forum) "On the morning going to the appointment, the light went off. I got to the service dealer, he hooked up a scanner, it read that my gas cap was defective. He asked if I fill my car up with gas and go and click more than 2 to 3 times after the gas is full. He said that I'm putting to much gas in. Over flow of gas goes into the charcoal filter. Don't over fill the gas tank. So far so good. Hope this helps you out."

[@Dashboardwarninglights]

@adsmith122 It’s interesting that overfilling the gas tank led to the Forward Collision Warning light appearing. Typically, this light is tied to the vehicle's forward safety system, not the fuel system. However, a malfunctioning gas cap or overfilling could potentially impact various sensors indirectly or create system errors if vapor pressure isn’t controlled correctly. By avoiding "topping off" the tank and securely fastening the gas cap with minimal clicks, you may reduce the chance of unrelated warnings appearing on the dashboard. Thanks for sharing this-it could indeed be helpful for anyone experiencing unexplained warning lights on their dashboard! 🙏👍

I had a recent break job done and might need to change my break oil , your saying it’s possible replacing the oil might be a solution thought that was interesting .

[@Dashboardwarninglights]

@@omarabdelrahman9775 The Forward Collision Warning (FCW) system is generally unrelated to brake fluid levels or the need for an oil change. However, several issues can trigger the FCW light, and maintenance work might inadvertently affect the system. Here are a few possibilities to consider: 👉 Sensor Obstruction or Misalignment: During a brake job, if the sensors related to the FCW system were accidentally bumped or obstructed, it might trigger the warning light. 👉 Brake System Issues: Although not directly related to FCW, any significant issue with the braking system could potentially affect the overall safety systems in your vehicle, causing warnings to appear. 👉 Electronic or Software Glitch: Sometimes, after maintenance work, there might be temporary glitches in the vehicle’s software, leading to warning lights appearing. 👉 Low Brake Fluid: While this typically triggers a different warning light, it’s always good to ensure your brake fluid is at the correct level and that there are no leaks. 👉 Calibration Needs: After certain types of maintenance, sensors may need recalibration to ensure they’re functioning correctly. If the warning light persists, it would be wise to consult your vehicle's manual for specific troubleshooting steps or take your car to a dealership or a trusted mechanic to diagnose the issue accurately. They can reset the system or determine if there’s a more serious underlying problem.

Where are the forward sensors?

[@Dashboardwarninglights]

@jonitaite6800 Forward sensors are typically located at the front of a vehicle or machine and include various technologies such as radar, lidar, ultrasonic, and cameras. They are usually positioned in strategic locations like: Front Bumper: Common placement for radar and ultrasonic sensors for detecting obstacles and assisting in parking. Grille: Often houses radar sensors to aid in adaptive cruise control and collision avoidance. Windshield: Camera sensors for lane-keeping assistance, traffic sign recognition, and forward collision warning. Side Mirrors: Can contain cameras or sensors to cover blind spots and provide additional forward-looking coverage. Front Fenders: Sometimes used for side-facing sensors that still have a forward-looking component for detecting cross-traffic. These placements ensure that the sensors can effectively monitor the area in front of the vehicle or equipment to enhance safety and operational efficiency.
