Does Opening the Car Door in the Rain Have Any Impact?

No impact. There are drainage holes inside the car door, and any water that gets inside will be quickly drained out. Here are some vehicle maintenance tips for rainy days: 1. Clean the car body: After using the car on a rainy day, promptly clean the exterior to prevent acidic substances carried by rainwater from lingering on the surface and causing damage. 2. Maintain the chassis: Rainwater splashed up during driving can easily wet the chassis, so it's important to maintain the chassis promptly after driving to prevent corrosion or rust. Additionally, when parking outdoors, avoid low-lying areas to prevent water immersion and damage to the chassis. 3. Check the wipers: To ensure clear visibility during rainy days, drivers often use wipers, but increased rainwater puts more pressure on them. Therefore, carefully inspect the wipers for any missed spots while driving, and replace them immediately if necessary to reduce the risk of accidents. 4. Air conditioning dehumidification: Using the car on rainy days inevitably leads to interior dampness. You can turn on the air conditioning for dehumidification or use desiccants and air fresheners. Once the weather clears, open the car doors when not in use to allow air circulation and remove interior moisture. 5. Electrical circuit check: Using the car on rainy days can easily cause electrical circuits to become damp. After driving, remember to check for any water ingress in the circuits to eliminate potential electrical faults caused by dampness.

I've been driving for decades, and getting caught in the rain when opening the car door is a common occurrence. The key lies in how you handle it. Rainwater entering the car, especially around the door seams, can soak the seats and carpets, leading to mold growth and unpleasant odors over time, which are a hassle to clean. I've experienced it myself—once after heavy rain got inside, the electronic socket under the seat short-circuited due to moisture, costing me hundreds in repairs. I recommend avoiding it when possible by parking under cover or a carport and carrying a small umbrella to shield the door when opening. Additionally, rainwater may contain dirt and acidic substances. A light splash on the car paint is harmless, but long-term accumulation can accelerate rusting. Check the weather forecast before heading out and adjust your plans flexibly to reduce risks. Occasional incidents aren’t a big deal, but developing good habits better protects your beloved car.

As a health-conscious average user, I find getting drenched while opening the car door in the rain quite impactful. Rainwater isn't necessarily clean—it may contain urban pollutants or bacteria that can cause skin irritation or even allergies upon contact. I'm especially cautious when children are around to prevent slips or catching colds. The interior suffers too; water seeping into carpets and plastic components breeds bacteria and odors, compromising cabin air quality. Keeping a foldable umbrella or car cover handy is advisable, plus quick door openings minimize exposure. Safety-wise, wet surfaces are slippery, and rainy driving is challenging enough—extra caution never hurts. Health comes first; avoiding rain when possible is wise.

Getting car doors wet in the rain? Not a big issue in the short term. Rainwater may enter the car, dampening seats and carpets. An occasional occurrence is fine, but repeated exposure could lead to mold or odors. Getting yourself wet is uncomfortable, and rainwater isn't clean. Simple solutions: Use your key fob to remotely unlock and open doors in advance, park under a covered spot, or just wipe dry after opening. Don't worry about the paint—normal rainwater won't cause immediate damage. In short, prevention is better than cure; just avoid prolonged exposure and you'll be fine.
