On approximately December 23, 2022, I notice that the UV protection coating on the hood and roof of my SUV is no longer protecting these areas of my vehicle. Which I am now concerned could lead to rusting on my 2018 SUV. I reported this issue after seeing many complaints on the WEB for the same problem by vehicle owners. A Chevrolet dealer mechanic also informed me of customers voicing my concern about the UV-protecting coating issue. I'm worried this issue will continue and affect the painting of my entire vehicle.

My 2018 Suburban required over $400 worth of expenses to replace a valve and recharge the freon in the ac. Less than a week later it required a new condenser and another $1250 in repair. The condenser was recalled in 2015-2017 Suburban and it sounds to me like it should include the 2018 model year as well. I should not have to put more than $1650 in repairs for that into a vehicle that is less than three years old. I have a family of six including a nine month old and it is not safe in the summer heat to be driving them around as this is the only car we have that fits the entire family. My wife is a doctor and frequently working at the hospital during this pandemic so it is the only remaining vehicle I have and the only one that fits the rest of the family.
