Is It Serious If the Car Trunk Gets Rained On?

Getting the car trunk rained on does not have a significant impact. Hazards of water entering the trunk: Water accumulation in the trunk can easily lead to rusting, and in severe cases, perforation may occur. The spare tire compartment in the trunk is positioned lower, making it prone to water accumulation if water enters. If the moisture and water vapor cannot escape, it can easily cause the car's interior to become damp and moldy. How to handle water entering the trunk: Drain the water as soon as possible. There is a rubber drain plug at the bottom of the spare tire compartment in the trunk; removing it will allow the water to drain. Afterward, promptly locate the source of the leak. Check if the trunk lid is deformed, ensure the surrounding rubber seals are intact, or enter the trunk, close the lid, and observe where light comes through to mark the problematic areas.

The trunk of my small car often gets rained on, and after driving it for several years, I don't think it's a big issue. There's a rubber seal strip on the trunk door that does a good job of blocking water. Occasionally getting a little wet won't cause leaks. After rain, I make it a habit to open the trunk and check. If it's a bit damp, I wipe it dry with a cloth or leave the lid open for a while to let the air circulate and dry it out. The key is to avoid letting water accumulate in the spare tire well, as it can easily rust and affect the parts. During regular maintenance, I check the seal strip for any cracks, and replacing old ones promptly saves money in the long run. Overall, getting rained on isn't a major concern as long as you deal with it promptly, so there's no need to constantly worry about it affecting the car.

I've encountered quite a few trunk leakage issues while repairing cars. Heavy rain can be quite troublesome. Aging sealing strips or door deformation can easily lead to water seepage, which accumulates in the spare tire compartment and causes rust and corrosion to the spare tire and tools. Water-soaked wiring harnesses, like the rear light cables, may short-circuit and burn out. Repairs can be expensive and time-consuming. I suggest fellow car owners not to overlook this after rain. First, check if the bottom of the trunk is wet and use a towel to soak up any accumulated water. If the sealing strip is cracked, repair it with glue or replace it. Prevention is key; regular maintenance can avoid major risks.

From a safety perspective, don't underestimate the seemingly minor issue of rainwater in the trunk. Water leakage may cause short circuits in electronic equipment, such as reversing radar failure or rear lights not working while driving, which could lead to accidents. Excessive water accumulation can corrode the metal underbody, weakening the vehicle's structure over time—even making sharp turns a concern. I regularly dry the trunk and place a waterproof mat to absorb moisture. When parking in the rain, avoid positioning the rear door against the rain to minimize leakage risks. Addressing these issues promptly ensures peace of mind while driving.
