I don't know if this is ever happened to any other cars out there but this is my personal experience driving Perodua Alza car during rainy days. When the road was flooding with water i just drive through it and i can feel the water level was obviously reaching the under carriage of the Alza and the range of the flooded road probably within 7 to 10 meters. I was driving a little bit slower to avoid wter splashing on other cars.
After going through the water i can feel the steering is getting difficult to twist, I thought it should be okay and afterwards it becomes completely jammed / stuck and i couldn't event twist a little to turn around on a small corner forcing me to stop.
I've never had experienced like this before despite driving through the waters quite a number of times. However this time is different and make me realized how dangerous it can be especially when driving in high speed on the road and having your steering suddenly jammed out of the blue.
In the end forced myself to stop to let the water dry away. A couple of minutes later the steering is back to normal. I've made some research on the internet there are many people complaining about their power steering stuck in wet condition. So this confirm not only Perodua Alza but it can happen to any cars.
If you have any comments, experience, and tips to solve this let me know i am looking for a solution but i won't go to the mechanic without knowing it myself because the technician tend to do something else then fixing the problem - so i want them to check exactly the problem.
