Hyundai

Been going back and forth with Hyundai over my 2015 Sonata, car was in shop three times for (cam positioning sensor) the last time it was in shop for 56 days, my problem is Hyundai wanted me to sign off on the repair and they would give me 4 payments back. I refused to sign off because I could never take car in for the same problem and Hyundai would not be responsible for this repair . The time I was put out because of this and Hyundai gives nothing to make this right, this will be the last time I buy a Hyundai ! They try to give you hush money so there name is not hurt. was told I would get platinum coverage, and my xm raidio trial back that I couldn't use because of being in the shop so long.
