The attaching transmission gear selector shaft to the control valve lever may not have been adequately tightened. This could result in the transmission not actually being in the gear indicated by the selector lever. In addition, the transmission display in the instrument panel may be incorrect. If the gear displayed is different from the gear engaged, this could result in unexpected vehicle movement and a crash. Dealers will check the affected nut in the transmission shift lever linkage and tighten if as necessary. The Nissan recall number is R3009.
