2011 Kia Rondo Engine problems

I have a 2011 kia rondo (148,000 kms). For the past few months, when driving on wet roads, I lose control of the power steering - it just stopped working. The battery light comes on during this period for between 5-30 seconds as you loose almost all control of your vehicle's steering. Just as your vehicle gains power steering again, a screeching sounds comes from the engine compartment (maybe belts re-engaging). It has been raining here the past week and the issue has happened about 6 times. Sometimes directly after driving through puddles, and sometimes just while driving. The issue only occurs though when the roads are wet. This is a major safety issue!!! *Tr
