Generally, water enters through the air intake. However, there are other reasons as follows: 1. External water entering the car: External water mainly enters through the door sealing strips; improperly closed windows; door window sealing strips; guide channels, etc. Check if the door sealing strips are aged or cracked, as poor sealing can also cause external water infiltration. 2. Internal leakage entering the car: Regarding air conditioning drainage failure, it is mainly due to the blockage of the air conditioning drain outlet, preventing water from draining outside, causing it to overflow into the car through gaps in the evaporator box. Check if the sunroof and door drain holes are blocked.

Last time I suddenly noticed water seeping into my Lavida, so I carefully inspected it and found the most common issue was a loose sunroof seal, especially if leaves or dirt accumulate in the sunroof tracks—it tends to drip during rainy days. Next, the door seals aging or deforming is another problem; the rubber material hardens and cracks over time, allowing rainwater to seep through the gaps. Aging windshield installation adhesive is also a hidden risk. Sometimes, if the AC drain pipe clogs, water can backflow into the cabin, not to mention that damaged ventilation grilles on the chassis can become a direct path for water ingress. All these can lead to soaked carpets or even short circuits in the electrical system. I think it’s important to stay observant, regularly clean the sunroof channels, and check the rubber seals. If water stains are spotted, address them immediately to prevent small issues from escalating. It’s also a good idea to test the sealing effect during car washes—spray water with a hose to identify leaks and replace faulty parts promptly to save hassle later.

My Lavida has been running for five or six years. One day after the rain, the car was full of water stains, so I checked step by step: starting with the rubber seal around the door, which had aged and become loose, allowing rainwater to easily seep in; then the sunroof wasn't closed tightly or the rails were dusty, causing poor sealing; loose glue at the edges of the windshield could also lead to leaks; other points like blocked air conditioning drain pipes causing water to back up; the most unexpected was that clogged floor vents also drew water inside; water ingress not only wets the carpets but also rusts metal parts and triggers electronic faults; solving it requires replacing aged seals, cleaning sunroof rails, and reinforcing glue strips; during routine maintenance, remember to check these areas quarterly, choose dry parking spots on humid days to avoid water accumulation; timely action can preserve your car's lifespan and save on repair costs.

I've encountered the Lavida water ingress issue multiple times, with common entry points being: failed sunroof seals (especially clogged drainage rails causing leaks), aged or damaged door weatherstrips allowing direct seepage, loosened windshield adhesive creating hidden entryways, clogged AC drains causing water backflow, and damaged underbody vent grilles admitting rainwater. Such water intrusion corrodes metal components, damages electrical systems, and poses safety hazards. Immediate actions recommended: inspect sunroof channels, clear blockages, replace rubber seals periodically. Preventive measures include parking in dry areas, testing seal integrity during car washes, and addressing issues promptly to avert accident risks.

As a frequent driver of the Lavida, I've concluded that water ingress typically starts from dirt accumulation in the sunroof rails or aging seals, allowing rainwater to seep into the cabin; deformed rubber strips along the doors are also common leakage points, while loose windshield adhesive or clogged AC drain pipes can exacerbate the issue; damaged floor vents pose a major hazard. Water intrusion may lead to moldy carpets and electrical shorts, compromising driving safety. Simple preventive measures include monthly cleaning of sunroof debris and checking rubber strip elasticity; quarterly inspections of windshield edges and AC vents; prompt repair or replacement of any leaking components to ensure optimal sealing and prevent long-term damage.
