“The passenger front seat belt will not retract. Also, the dashboard lights went out while driving making it very hard to see speed/fuel/gear selection. These are both safety concerns that should be recalled. We can send you a picture of the dead dash if needed. Also video of a stuck seat belt. Thanks, kurt.”
