What's wrong with the brake light failure of Haval H2s?
4 Answers
Haval H2 brake light failure indicates that there may be a problem with the car's braking system. It is recommended to go to an auto repair shop and use an automotive computer diagnostic tool to check the anti-lock braking system (ABS). By reading the fault codes, the issue can be identified, and then repaired according to the fault content. If it is an intermittent fault, use the automotive computer diagnostic tool to clear the fault codes, and the fault indicator light will turn off. Severe brake pad wear: The car's brake pads are equipped with a manufacturer-set brake pad warning line. When the brake pads reach their limit of use, an alarm will be triggered. It is necessary to regularly inspect the tire brake pads and use measuring tools to check the thickness of the brake pads. If the wear is significant, immediate replacement is required. Low brake fluid: When the car brakes, brake fluid is compressed into the pipelines and brake calipers. If the brake fluid level is low, the fluid level sensor will detect it and trigger an alarm through the fault light. Regularly check the brake fluid reservoir to ensure it is not low on fluid, and add brake fluid immediately if needed. Wiring issues: There may be an open circuit in the wiring affecting the dashboard warning light. Use a multimeter to check the brake pad warning circuit, brake fluid level warning circuit, and handbrake switch circuit to detect any wiring problems.
I also had the issue of brake lights not working on my Haval H2S, which was really frustrating. The most common cause is a burnt-out brake light bulb, as it operates frequently and is prone to damage—simply replacing the bulb can solve the problem. But don’t rush to replace it; a blown fuse is also a common culprit. Open the hood, check the fuse box for the brake light fuse, and try replacing it with a new one. If that doesn’t work, poor contact or a short circuit in the wiring might be to blame, especially in older cars where wires can degrade—inspect for any damaged or loose connectors. A faulty brake light switch is more critical; if it doesn’t respond when you press the brake pedal, the lights won’t illuminate, and this requires professional diagnostic equipment. In short, driving safety comes first—don’t drive with faulty lights. Get them fixed at a repair shop immediately, and make it a habit to check your car lights monthly to prevent future issues.
As a female car owner, I'm quite sensitive to the brake light failure of the Haval H2S. A while ago, my car had no lights, which was very dangerous. The reasons are mostly due to the bulb reaching the end of its lifespan or a blown fuse. A simple solution is to have family members observe whether the lights come on when the brake is pressed. If not, replace the fuse in the fuse box with the same model. Short circuits in the wiring are also common, especially after rainy days when moisture can cause issues. A faulty brake switch is more troublesome as it controls the signal for the lights' operation, and this is something you can't fix yourself—you'll need to consult a mechanic. Remember, light failures increase the risk of rear-end collisions, so I recommend visually inspecting the rear of the car before driving and addressing any issues promptly to ensure a safe journey. After all, family safety is the most important thing—don't skimp on costs or effort.
I've repaired quite a few Haval H2S vehicles, and brake light failures are usually caused by three main reasons. The most straightforward is a burnt-out bulb—just replace it with a new one, which is cheap and can be done yourself in five minutes. A blown fuse due to excessive current is another common issue; simply locate and replace the fuse in the fuse box at the lower left of the car. If neither of these solutions works, it might be a short circuit in the wiring or a faulty brake light switch. The switch is located near the brake pedal and can sometimes get stuck, requiring inspection and adjustment. Don’t ignore this issue, as driving at night without brake lights can easily lead to accidents. It’s best to pull over and wait for professional help. Regularly paying attention to your car’s condition can help avoid major repairs.
