2020 Subaru Ascent engine problems

We are on our second subaru ascent, first one bought back for the same issue. Upon starting the car, the cabin will fill with a strong smell of raw fuel (not exhaust). The car will also fill with the smell if running while parked, remotely started, etc. The smell is also noticeable when turning off the car and on the outside of it.

Odometer: 1,289 miles vehicle was in motion on a city street, drove 3 miles away from home. Battery light came on, vehicle started to overheat and check coolant indicator came on. Opened hood to smoke and serpentine belt had shredded. Coolant was sprayed all over under the hood. Vehicle was towed to dealership who replaced serpentine belt and appears battery light and overheating was caused from belt failure.
