After reading several of the reviews I had to commit on several of your issues ...
I am unable to clean the windshield/dash to stop the reflecting.
On sunny days it's dangerous.
I have tried several high end windshield cleaners and nothing has helped.
Unexplained noise ...
It's been driving me nuts since I bought the vehicle. It rattles even the slightest bump in the road. I think, I figured it out.
The glove box rattles.
I used some heavy paper and jammed it in and it helps.
The interior ... It scratches terrible.
Anything leaves a mark!
I dread the reduced trade in value due to scratches.
I do allot of thruway driving. I average between 29-32 mpg.
I do not have a heavy foot!
Any stopping or idling greatly reduces the mpg.
I have owned my Sportage for nine months and have 19,500 miles.
Improve window glare, better quality control for those little noises, and improve the interior!!
