The fault issue with the Qin Plus DMI is oil burning. Below is an introduction to the BYD S6: Introduction: The BYD S6 is BYD's first SUV, positioned as a mid-to-high-end domestic SUV, which was launched in September 2010. Its dimensions are 4810/1855/1680mm in length/width/height, with a wheelbase of 2720mm, ranking among the top in its class. A minimum ground clearance of 190mm ensures excellent off-road capability. Powertrain: The S6 offers three engine options: 1.5T, 2.0L, and 2.4L, available in four variants: Manual Luxury, Manual Premium, Automatic Premium, and Automatic Ultimate. It is equipped with either the BYD483QB engine or the Mitsubishi 4G69 engine. The BYD483QB is an engine independently developed by BYD, featuring Bosch's fuel injection management system and BIVT variable intake system. The BYD S6 boasts a stylish and dynamic exterior design with sharp lines, fully embodying the bold character of an urban SUV.

I've been driving the Qin PLUS DM-i for over a year, and I feel its common faults mainly focus on the hybrid system and battery. There's sudden shaking or delay during power switching, especially when shifting from electric to fuel mode—the car vibrates like it's hiccuping; battery degradation is also quite annoying, with the range directly halving when using AC in summer, and charging is painfully slow. Additionally, that large infotainment screen occasionally freezes, leaving the navigation stuck in place, requiring a restart to fix. Minor issues like weak AC cooling make long drives uncomfortably hot. I later realized that regular battery health checks are crucial—it's best to get a comprehensive inspection at the 4S store every six months, since safety comes first.

As a young car enthusiast who often tinkers with vehicles, I find the electronic systems in my BYD Qin PLUS DM-i to be quite problematic. The onboard software frequently has bugs—for instance, after an OTA update, the reversing camera lags or fails, requiring a manual factory reset. The touchscreen is sluggish, making it difficult to even operate the air conditioning. These bugs leave me scrambling, especially on the highway. That said, the hybrid mode runs stably, though the battery occasionally drains quickly, possibly due to aging wiring. I recommend paying attention to software update notifications and manually checking connection ports to avoid short circuits. Safety-wise, these minor glitches don’t usually affect driving, but it’s best to keep an emergency manual handy.

From a daily usage perspective, the powertrain of the Qin PLUS DM-i can sometimes be temperamental. The hybrid module malfunctions, causing the engine to start unexpectedly with really loud noise. The battery charging efficiency is also low, taking an hour longer to fully charge than the claimed time. Additionally, the brake alarm frequently triggers false warnings, which is quite startling. Fortunately, the car's reliability is decent, and most issues can be resolved through software updates at the 4S store. I recommend regular battery maintenance and checking the wiring connections.

I'm concerned about the safety implications of BYD Qin PLUS DM-i malfunctions, such as sudden power interruptions during traffic jams which can be terrifying; or the air conditioning failing to cool in summer, causing headaches during prolonged drives. Most of these minor issues stem from battery thermal management or circuit aging, especially given the complexity of hybrid systems which are prone to glitches. My advice is to perform monthly self-checks on vehicle condition, replace filters and clean dust to prevent major repairs through early intervention. Road safety is no trivial matter - pull over immediately if any issue arises.

After long-term use of the Qin PLUS DM-i, I found that battery degradation is a persistent issue, with a noticeable drop in range after three years; the poor hybrid switching leads to a surge in fuel consumption, costing extra on gas each month. Software glitches like erratic navigation are also annoying, though they don't affect driving. Proper maintenance can prevent many problems—I insist on quarterly checks of electronic modules and the cooling system to ensure stable operation. Choosing this car was still a wise decision, but regular upkeep is essential.
