Fully submerged cars are not easy to repair and require significant time and money. The hazards of water-damaged vehicles include the following: Impact on the interior: Prolonged soaking can cause materials like carpets and seats to deform, become rough, produce odors, and foster bacterial growth. Moisture in the wiring harness under the carpet can lead to short circuits due to dampness. It is best to replace all soaked components to avoid long-term damage. Impact on door panels: The sound insulation material inside door panels needs replacement after water exposure. The four-wheel bearings must also be replaced because their seals contain lubricating oil, which can corrode and deteriorate, losing its lubricating function and compromising driving safety.

Fully submerged cars are really difficult to repair. With years of car repair experience, when water completely submerges the vehicle body, it can enter the engine block, potentially causing the engine to seize and fail to operate; electronic control systems like the ECU or computer modules may corrode and short-circuit after being soaked, making repairs complicated; waterlogged interiors can develop mold and unpleasant odors, with high treatment costs. Typically, repair costs start at tens of thousands, and it's often not worth it for older cars. It's advisable to seek professional assessment, but in most cases, scrapping the car is more practical. After flooding, promptly tow the vehicle to avoid further damage, and conduct regular maintenance to prevent issues.

As a flood-damaged car survivor, my vehicle was completely submerged and took months to repair, costing a fortune without a full recovery. After the engine was overhauled due to water ingress, it always makes strange noises. Electrical system short circuits have left the AC dysfunctional, and the moldy interior stinks. Safe driving has become a concern. The repairs were time-consuming and labor-intensive—worse than scrapping it initially. Flood-damaged cars harbor many hidden dangers, like unreliable brakes posing significant risks. My personal lesson: avoid them if possible. Investing in a new car is more reliable and economical.

From a cost-saving perspective, most flood-damaged cars are not worth repairing. Cleaning the engine, replacing electronic components, and dealing with mold and rust can easily cost over ten thousand. If the car is of low value or old, the repair costs may exceed its worth. Insurance claims can provide some help, but depreciation is significant. Prompt action after flooding can minimize losses, but the decision should be based on a thorough assessment of the car's condition. High costs and risks make it generally difficult to recoup the investment.
