As an owner of the Haval Big Dog, I've been using this vehicle for almost two years now. Initially, the battery drain issue was quite annoying—the battery would die after just a few days of parking. Later, the manufacturer released a software update at the end of 2022 to optimize the sleep current control, and I haven’t encountered the issue since updating. I recommend paying attention to daily vehicle habits, like not leaving the dashcam or audio system on overnight, and regularly checking battery health at the 4S store. Battery life is greatly affected by environmental conditions, especially in cold weather when power drains faster. Keeping the vehicle parked in a ventilated area can help reduce problems. Overall, the issue has been largely resolved, but older models need proactive upgrades—don’t slack off or ignore maintenance reminders.
After years of car repairs, most power loss issues in the Haval Big Dog are caused by software bugs or aftermarket installations. The manufacturer has fixed circuit faults through OTA updates, with most owners reporting significant improvements. During troubleshooting, always check the battery and fuses first, avoiding interference from modifications like additional lighting. It's recommended to test voltage monthly with a multimeter; normal readings should be above 12V. Power loss not only affects startup but also damages the battery, so timely repairs save money and ensure safety. Technically speaking, system optimization has reduced power consumption, but long-term maintenance remains essential.
