Battery health has gone down to 31% I’ve had it at a dealership three times and they don’t know what’s wrong. They can’t figure it out, but my mileage has dropped significantly.
I bought the car with 9 miles on it, and when I tried to use the windshield washer, it didn't work! I took it to the dealer, and they refused to fix it! They said the car was infested with mice and that it was my problem!!! The car is made with defective materials! All hoses and foam in the car are made from soy beans!! That is rat and mouse food!!!
