“Side door is malfunctioning. Had to drive home with it open. Granddaughter had to move to rear because I couldn't get it shut after she got in. Frightening experience. Son-in-law had to use force to get it shut. Haven't used in 3 months until I could afford to have it looked at. There was an extension added to the warranty but said I wasn't eligible. $2,125 + tax to fix!!!!”
