I have a new 2019 Defender Crew XMR, I went to take my little girl for a ride and it has no power I put it in high gear and gave it gas bc I was going to ride her down dirt road and at 4600 rpms it started saying wrong gear and jumping and I had the gas pedal to the floor and it wouldn’t go faster than 4600 rpms and speedometer doesn’t work so I put it in low gear speedometer still don’t work and will only let me go up to 5500 rpms. Any ideas of what could be wrong, I have checked fuses, battery connections as well as tried unplugging the battery to see if it would reset itself.
