My wife took her 2008 Kia Rondo into the dealer and had an oil change and possibly something else done.
The next time it rained (a few days later) and the warranty had about 100km remaining (99900km), she hit a puddle on a really wet day and the power steering light on the dash came on and another light. It happened for a couple of seconds and then it was fine. It has only happened to me when I took right handed turns and hit a puddle. When the lights do come on the power steering locks up for a few seconds and there is a screeching noise under the hood although hard to hear with the wipers going. The dealer looked at it and said everything was fine and they had never heard of this before, since then my wife has had it happen multiple times on wet days (usually really wet days).
I have done extensive research online and there are a couple of instances of this happening in the US. KIA Rondo Steering - 2007 KIA RONDO Problems With Steering

The car was fine until the dealer in Nova Scotia did that final checkup on the car before the warranty was completed. Maybe the idler tensioner got hit or something however there is no way to know or maybe the belt was going and it just seemed to go when the warranty was up :-). The dealer has been very good in this situation and they are very good to deal with compared to other dealers in the past with different brands.
I don't think it is the fuel pump because it only happens in wet weather. Possibly the idler tensioner and/or the belt slipping. Maybe the alternator?
We are very afraid of highway driving and when we have our children in the car. The air conditioner bearings seem to be getting noisy (possibly the bearings) could that be putting pressure on the belts or is it the idler tensioner?
The dealer is willing to do one repair but I don't know whether we should replace the idler tensioner and the belt or replace the power steering pump. I took a video of it happening but the dealer said if they cannot duplicate the problem they cannot fix it or diagnose the problem.
I am hoping to take the car in sometime in mid December to replace the idler tensioner and the belt but I want to ensure I do some driving in the rain to ensure this is still happening before I get it fixed. i will update
