Hopefully not any since I have done it three times in the last couple weeks. I just got my car and the roads are salty in my neck of the woods. I drove it home from the dealer and pressure washed it before I put it in the garage. I took it out two more times since then just to make sure nothing was wrong with the car since the dealer gave me a 30 day warrenty. Each time I power washed the whole car including under carriage. I don't think power washing under the car will hurt anything. Just keep the water away from the electronics.

Be carefull in the area of the 02 sensors, as well as the area below the battery (computers).
Really you'll not have issues unless you power wash those areas directly with +1600psi.
