Engine Exhaust System problems of the 2020 Honda Accord

I leased my vehicle a year ago, I had electrical issues with my old car so I wanted a brand new car that was reliable and safe for me and my children. In the first months the car was fine but after about 4 months the car would smoke from the exhaust pipes randomly. I took it for maintenance as the car system directed but the repair shop never said there was anything wrong with the exhaust system. A month or so past and one day I got in the car and all the lights on the dash board were in. I was so freaked out because it was a new car and no warning lights should of been on. I took it to Honda repair services and they found out that a mouse went in my engine and chewed some of the electrical wires. The cost of the repair was 1700 which is extremely outrageous prices to me. Anyway I was at hospital at work and I got the call from the mechanic saying I would have to pay out of pocket because it wasn't a factory default. So I went home and did some researching and I found out Honda had been using soybean it peanut butter oil to lube the wiring, and that's what attracts rodents to your engine. It also started that Honda wire protection tape was out of stock because some many customers had there car wires eaten by rodents. So I was so pissed off that I called Honda corporate and they told me there is nothing they can do. I feel as though this is a big safety issue, why would Honda put parts or use oils in the car engine that attracts rodents. This to me is, unfair to honest hard working customers that pay Honda there money expecting to have a safe and reliable vehicle. Now I just found out there is a recall on the vehicle because the car started smoking out the exhaust pipes once again. I am very disappointed in Honda.

The car rattles on the rear where the exhaust end when I turn it off. It used to not do that rattling before. The car vibrates when the car is coming to a stop and then continues when idling. It feels like I am sitting at a vibrating chair. The engine works very rough when idling.
