What to Do When the Car Jerks After Driving Through Water?
3 Answers
If the car jerks after driving through water, first check whether the transmission has been flooded. If so, replace the oil. Below is a partial introduction to the causes of car jerking: 1. Special circumstances: Check whether the ignition system has been flooded. Sensors or the intake system being flooded may cause the air filter to get wet, thus affecting the air intake, which may contain a small amount of water. 2. Causes: The transmission oil circuit may be clogged or not smooth. The oil circuit plate may be worn, or the transmission may not have been serviced for a long time, leading to deterioration and reduced lubrication. The transmission filter may be too dirty, reducing filtration efficiency and allowing wear particles to enter the valve body.
Experiencing jerking after wading through water is quite dangerous. I've encountered similar situations before, usually caused by water entering the intake pipe or ignition system. The first thing to do is stop the vehicle immediately - don't force it to keep running, as this could damage the engine. Check if the air filter is soaked; if wet, it needs replacement or thorough drying. Moisture on spark plugs or ignition coils can also cause ignition problems, making the car feel like it's struggling. There might also be short circuits in wiring that affect sensor performance. Don't attempt to restart the engine - call for a tow truck immediately and have it inspected at a professional repair shop. Remember: never wade through water deeper than half your tire height, and maintain clean air intake during regular maintenance. When driving through water, maintain slow speed and conduct thorough post-wading inspections to prevent more serious issues.
My car kept shaking after the last time it went through water, which really scared me. The possible reason is that water entered the exhaust pipe or intake tract, affecting the cylinder ignition and causing hesitation during acceleration. Turn off the engine immediately, and you can do a simple check yourself. Open the hood and feel the air filter: if it's wet, take it out to dry or replace it. Check the spark plug position for any water marks, wipe it clean, and try again. If that doesn't work, the circuit fuse might have blown; try replacing it. However, if the water was deep, the risk is high, and I recommend going to a 4S shop for a comprehensive inspection—don't skimp on minor repairs. Regular car washes to maintain good chassis sealing can prevent such problems from occurring.
