Last week I noticed a bubble on the lower front lip of the hood on my wife's 2018 Equinox (Pepperdust color). Took it to the dealer and they said that for some reason that only the 2018's in Pepperdust is experiencing this, and from what I gather from the body shop advisor it seems pretty common. Since the car is 4+ years old and has 47,000 miles it's out of the bumper to bumper warranty but will be covered under the corrosion warranty. They're going to replace the entire hood (it's made of aluminum which I did not know). Just curious if anyone else is having that problem.
