What causes the brake lights to stay on in a 2013 Jetta?
2 Answers
The following are the specific reasons why the brake lights of a Jetta may stay on: 1. Brake switch failure: This is usually caused by poor contact between the brake pedal and the brake sensor switch or a faulty sensor switch. 2. Worn or aged brake pads: Worn or aged brake pads can also cause the brake lights to stay on. It is necessary to check the thickness of the brake pads. If the thickness is below the specified value, generally 0.8cm, there is a high risk of the pads breaking while driving, which could be dangerous. 3. Low brake fluid: A lack of brake fluid may also be accompanied by noticeably reduced braking power, and in severe cases, a complete loss of braking power.
For the 2013 Jetta with the brake light staying on, the issue is usually with the small switch behind the brake pedal getting stuck or broken. I've encountered this myself when driving an older car. That switch is what tells the car whether you're pressing the brake or not. If it gets water inside or wears out, it can get stuck, causing the light to stay on. You can try pushing the pedal by hand to see if it springs back. If it doesn't respond, you can pull the fuse to temporarily cut the power, but don't drive the car like this, or the battery will drain quickly, especially in winter when it's more prone to stalling. This problem is quite common in older Jettas, and most of the time, replacing the switch will fix it. You can buy one on Taobao for a few dozen yuan and install it yourself or take it to a small roadside shop to save some money. Remember to turn off the lights after checking to avoid midnight hassles—safety first!
