SoCal gets extremely hot! Even cars with heavy duty cooling will heatsoak.. Theres really nothing you can do. Make sure you use a full synthetic oil not the crap syn blend from factory!
Okay go to dealer have them start touching up your new car then? This is sound advice wait for your car to break in couple thousand miles and see if its still happening..
I have a Charger R/T and its the worst car iv'e ever owned also the slowest from factory. I hate everything about the car except that people think im a cop and move out of my way. I will be buying a 2019 Mustang GT PP2 taking a 5k loss on my charger.
I like how in the beginning you imply that you don't "rag" on your car like that's how engines fail.
Ive redlined all my cars from day one and never had a single motor problem. Hope your issue gets resolved
