Hey there. From the shaking issue (https://www.yourmechanic.com/services/car-is-shaking-or-vibrating-inspection) that you're describing, you'll need to have the tires and rims checked for bent rims or tires that are out of balance. If you used tire sealer to seal one of the tires,...

With so many electrical problems, I would start by checking the battery (https://www.yourmechanic.com/article/how-to-check-a-car-battery) first.
