What are the effects of water reaching the gear lever?
2 Answers
The effects of water reaching the gear lever are as follows: 1. Damage to internal electronic control systems: Since most cars are equipped with electronic control systems (such as engine ECU, ABS system, SRS system, GPS navigation, etc.), if water enters, it can cause short circuits in the internal IC circuit boards of the computer ECU and rust spots on the connector terminals, gradually leading to corrosion of metal parts. 2. Impact on wheel bearings: The seals of wheel bearings contain lubricating oil. If not replaced after being soaked in rainwater, the oil can corrode and deteriorate, losing its lubricating function. This affects driving safety, initially causing abnormal noises and potentially leading to breakage, endangering driving safety.
Last time my friend's car was flooded up to the shifter position, and the consequences were really severe. Water entering the transmission vent can cause the gear oil to emulsify, potentially rendering the entire drivetrain useless. The worst part is water seeping into the electronic shift module, where repair costs easily exceed tens of thousands. When they removed the carpets afterward, there was a strong smell of mud, and all the wiring harness connectors were severely rusted. Even after repairs, flood-damaged cars like this often develop lingering issues like chassis noises and rough gear shifting. It's recommended that if the water level exceeds the wheel hub center, you should never attempt to start the engine and immediately call for a tow truck. A mechanic once said that for every 10 cm rise in flood level, the repair costs double.
