What Causes a Car to Lose Power After Driving Through Water?

[Felix]

It is normal for a car to lose power after driving through water because water has a lubricating effect, causing the tires to slip when passing through flooded roads. Here are some explanations for why a car may lose power after driving through water: 1. Shallow water crossing: It may be that the spark plugs or some electrical components got wet, but they will be fine after drying. 2. Precautions: If the car stalls immediately after driving through water, do not attempt to restart the ignition switch. Otherwise, water in the intake manifold may be sucked into the cylinders, causing cylinder scoring and engine damage. You should immediately call for roadside assistance, have the car towed for inspection, and notify your insurance company. The loss of power could be due to wet spark plugs or ignition coils, but the most likely cause is that driving through water has increased air humidity, leading to blocked air intake and insufficient air supply, resulting in reduced power.
