2018 Honda Fit engine problems

My company vehicle has fluid leaking on the floor, the check engine light constantly coming on, the rear camera is intermittently inoperable and it smells like something has died in it (mold/mildew). Since I have owned the vehicle, I have reported these issues to Honda dealerships and they have claimed to fix the problems. I paid for an extended warranty and each time the dealership forced me to pay for repeat issues that repeatedly continued to happen. The battery died a more than once right after I purchased it.

The contact owns a 2018 Honda Fit. The contact stated that upon starting the vehicle, there was an abnormal rattling sound coming from the engine. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 55,000.
