What are the reasons for the brake light failure warning in the new Haval H6?
3 Answers
The reasons for the brake light failure warning in the new Haval H6 are as follows: 1. Brake switch failure: Mainly refers to poor contact of the switch behind the brake pedal. The solution for this type of brake light failure is relatively simple—just replace the brake switch. There are various types and models of brake switches available in the market, so find one that matches your vehicle model for replacement. 2. Brake bulb failure: Mainly refers to the brake bulb exceeding its service life. Currently, the service life of halogen brake bulbs is 1~2 years. To solve this issue, you can switch to LED bulbs, which have a lifespan of 5~10 years, consume less power, respond quickly with no delay in lighting, and are environmentally friendly with no pollution.
I've been driving for decades, and encountering brake light failure warnings is a common occurrence. With the all-new Haval H6, the most frequent issues are burnt-out bulbs or faulty LED units, especially in new cars where the filaments can break easily under high temperatures. Another major problem is the wiring—loose connections or poor contact from the factory can prevent current from passing through, triggering the system alarm. There's also the issue of blown fuses, which burn out to protect the circuit when the current is too high. A malfunctioning brake switch can also cause false alarms, failing to send signals to the control module when the pedal is pressed. I find this situation quite dangerous, as driving without brake lights increases the risk of rear-end collisions. I recommend first asking a friend to check if the rear lights are working, then inspecting the car's fuse box, usually located under the driver's seat on the left side. If the problem persists after manually resetting the system, take it to a professional shop immediately to scan for fault codes and prevent minor issues from escalating.
I recently purchased a new Haval H6, and the brake light failure warning suddenly popped up, which made me a bit nervous. Initial judgment points to an LED module issue—the new system's complex design is prone to false alarms, especially due to software bugs or overly sensitive sensors. It could also be caused by oxidized bulb contacts leading to poor connection and triggering the alert. A short circuit is another common cause, possibly from loose connectors during the new car assembly. My personal approach was to refer to the manual—performing a simple ECU reset by turning the car off and on again. If that doesn’t work, check the switch under the brake pedal to see if it’s stuck. Safety first—this issue could easily lead to a ticket, so I headed straight to the 4S store for a full inspection. They quickly diagnosed and fixed it for free by reading the error codes. Don’t delay; it’s risky on highways.
