considered so but to me its minor.. major if the height leveling is not flushed with body panel and the  engine cover hood.. definitely need to ask SC to fix it..

Don't mislead, misallignment is NOT the same as manufacturing defect 

That should be normal especially when the radiator fan is operating..for sure it will suck in air & rain water during driving..i will clean my engine bay once in every 3-4 months of driving.

Here at Alor Setar, i send my car for steam wash (no chemical or car shampoo are used) to clean the engine bay. It produce fairly good result in cleaning all the dirt. But the price is fairly high also    Since that i just clean (steam wash) the engine bay once in 3-4 month & the end result is good, for me it's worth the price of RM20 for steam washing the engine bay only. Steam wash the engine is safer for the engine coz it does not use the water jet, it use steam jet/spray instead which is better..the fine & hot steam jet will easily loosen the sticky dirt from the engine bay.

Previously, i did clean it by myself using the same method as u, but the result is as what u said 

Bro, I don hv...even after car wash oso don c tat..

Its normal if you wanna be 'hero' and run thru a big pool oh water, normal raining shouldn't slash like that.
