How to eliminate the brake light failure of Haval H6?

[AlexFitz]

Haval H6 brake light failure elimination methods: 1. Brake switch failure: mainly refers to poor contact of the switch behind the brake pedal, replace the brake switch; 2. Brake bulb failure: mainly refers to the brake bulb has exceeded its service life, can be replaced with LED lights; 3. Brake system failure: brake fluid pipe wear causing severe lack of oil in the brake system, low oil level in the brake fluid tank, professional repair at a maintenance shop is required. The Haval H6 is the flagship model of the Haval brand, with a strong presence, adopting Eastern-style future aesthetic design language, the exterior lines also fully demonstrate the powerful dynamic force, while the interior features a super-sensing future smart cockpit design.

Last time my own Haval H6 also had the brake light warning light come on. I first checked the simplest part: opened the trunk to see if the bulb was burnt out. The H6's brake light bulb is positioned outward and prone to impact, which can break the filament. After confirming that wasn't the issue, I checked the fuse box and found the dedicated 10A fuse for the brake lights - it had indeed blown. Replaced it with a new fuse, but the warning light stayed on after restarting. Probably caused by loose wiring connections or oxidation from moisture. Used sandpaper to clean the metal contacts on the plug and reinserted it firmly, which fixed it. If none of this works, you'd need to check the brake light switch located behind the pedal - those with good DIY skills can remove it to clean the contacts. As a last resort, take it to a shop to check the control module for error codes.

I've been driving this Haval H6 for over three years now, and the brake light fault has been reported twice. The first time, replacing the tail light bulb fixed it. The second time was more troublesome: the dashboard red light was on, but the brake lights were actually fine—it turned out to be a sensor false alarm. This common issue in the Haval series is often triggered by unstable battery voltage. I simply disconnected the negative terminal for ten minutes to reset the system, then pressed the brake pedal a few times before starting the car, and it worked. Later, I installed a voltage stabilizer, and the problem hasn't recurred since. Regular self-checks are key—water in the light housing can easily cause short circuits, and aging wiring harnesses are prone to insulation damage. Preventive maintenance costs far less than repairs.

The brake light warning light on the Haval H6 may not be caused by a bulb issue. Its braking system is equipped with sensor monitoring. Sometimes, oxidation or misalignment of switch contacts can lead to signal errors, causing the system to misjudge a fault. When the dashboard light comes on, check the micro switch behind the brake pedal—remove it yourself and clean the metal contacts with alcohol. Frequent opening and closing of the trunk lid might pull on the wiring harness, loosening the connectors; simply unplugging and reconnecting them might solve the issue. Occasionally, voltage fluctuations can cause the vehicle's computer to malfunction—park the car, turn off the engine, wait five minutes, and restart to see if the light goes off. If replacing bulbs or fuses doesn’t help, visit a 4S shop to use a diagnostic tool to read fault codes and inspect the wiring or modules.
