15 cm should be no problem. Below is the relevant introduction: : Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. It is sold in North America, China, CIS countries, and the Middle East. Envision: The Buick Envision is a premium midsize SUV launched by SAIC-GM. On December 18, 2018, SAIC-GM Buick announced the launch of the 2019 Buick Envision National VI version, equipped with a 2.0T SIDI direct-injection turbocharged engine + 9-speed HYDRA-MATIC intelligent transmission, fully compliant with the National VI emission standards.

I remember encountering a water crossing while driving before. The official wading depth for the Envision is said to be around 500mm, meaning the water only reaches slightly above half of the tire height. But that time, after heavy rain caused the river to rise, I estimated the water level was over 400mm and drove through. My car was fine, but my friend's car stalled. Actually, wading depth is related to the drivetrain—four-wheel drive performs slightly better, but it's still not worth the risk. I usually use the tire edge as a reference point: as long as the water doesn’t exceed the center of the wheel hub, it's safe. If the water is too deep, flooding the chassis or engine air intake can damage the engine, which is expensive to repair and dangerous. Now, I always check the weather forecast before heading out and take detours to avoid flooded areas—it's much more reliable. Experience has taught me that exceeding half of the nominal depth is prone to causing trouble. Safety first, after all.

As a seasoned SUV driver, I have some insights into the Envision's wading capability. Official data indicates it's around 500mm, and from my few experiences with shallow water crossings, it feels quite stable. However, exceeding this limit is risky as higher water levels might reach the air filter, potentially causing stalling or damage. I recommend checking tire wear and ground clearance during inspections, and immediately inspecting and cleaning the filter after wading to prevent sediment blockage. Modified vehicles may reduce this depth, so stock configurations are safer. Overall, 500mm is the absolute limit—when encountering deeper water, it's wiser to detour than risk it, saving both repair costs and time.

From a technical perspective, the official wading depth of the Envision is marked at 500mm, which is based on the height of the engine air intake. Water levels exceeding this may lead to water ingress, causing electrical faults and affecting the drive system. When wading, it is necessary to pass through slowly and steadily to avoid sudden acceleration that could splash water and damage components. The actual depth may vary slightly depending on the model, with higher trim versions potentially allowing slightly deeper wading. Compared to other SUVs, this figure is average, and checking road conditions before wading is crucial in daily use.

Driving through water poses significant risks. The recommended value for the Envision is 500mm, and I emphasize not to exceed this limit. Water that is too deep can flood the intake and exhaust systems, leading to engine failure or even fire. Before entering water, measure the depth using simple tools like a stick to gauge the water level. Safety strategies include driving at low speeds and turning on the air conditioning in recirculation mode to prevent water from entering the interior. If encountering unexpectedly deep water, it's safer to stop immediately and call for assistance.

I believe wading through water requires a balance between practicality and safety. The Envision has a wading depth of approximately 500mm, which is suitable for urban flooding or small streams. However, actual situations vary from person to person. For example, during the rainy season, I tend to be more cautious, keeping the water level below 400mm to avoid engine damage. After wading, it's important to check if the battery and wiring are damp. Regular maintenance can help reduce risks. Overall, I recommend assessing your capabilities and consulting professionals if unsure.
