2000 X-T, 47,000 miles
I've had the same issue for over a month. Currently driving without gauges approx. 90% of the time. 2 weeks ago an additional problem began occurring when the gauges are out. If accelerating while climbing, X-T begins to lose power, chuggs and bucks, coming nearly to a stand still.
FSU recall performed. Getting same response from Dealer service, if it's working when they have it they can not diagnose. Bull! Sources tell me the computer stores the failure codes.
It is so frustrating, I can drive for 15-20 minutes to service center no gauges, run in and try to grab a mechanic, gauges are back on. Geez!!
Long thread on Xterra owners club.com. I count about 9 X-T owners with the same problem on that site.
Someone checked a repair invoice and gave me this info. Code PO500, speed sensor circuit failure, P/N FP24814-7Z062.
I'll be screaming tomorrow to try and get this resolved!
