Well, I talked to my dealership about it and they said that its a problem with all lexus cars not the lexus SUVS. The guy said that there cars are more aerodynamic so the rocks slide on thema nd cause more damage done would a rock hitting straight on (i.e. the suvs). The best to do guys is to contact your dealership and talk to them about Clear Shield. Its a great product to protect your hood and everything int he front, cost money but its worth preserving your car before its to late <_< .
