only glitch was at about 3,500 miles. the abs/tc/slip lights all came on while in 2WD. WTH? the DIFF LOCK switch was found to be bad. so as instructed by nissan, dealer replaced THE WHOLE REAR AXLE! they do not just replace the switch. i am at 13,700 miles now. and just switched over to synthetic oil. been really impressed with the vehicle.
