I purchased my NEW 2024 Versa S 5 speed on [XXX] from Jim Click Nissan Dealership in Tucson, AZ. I brought it in to Nissan dealership 2 months later [XXX], 4200 mi, for complaints of surging, fluctuating fan speeds with air conditioning on high. They claim they couldnt reproduce problem. It continues to persist to this day as I write this on 4/20/25. I checked the alternator myself with multimeter on 4/12/25 & it revealed ACV ripple of 29-30 volts! Battery at rest 12.7 dcv, battery at idle 13.8 dcv, battery 13.9 dcv under load, and repeatedly producing same values on morning of [XXX], just minutes before bringing car in to Jim Click service appointment for follow up of fan fluctuations & request for alternator check up. However these data results conflict with Jim Click Nissan Dealership diagnosis on 4/18/25 service visit when they stated and documented that the charging system tests all passed & alternator is fine, and witnessed no a/c fan fluctuation. Thus no repairs done, and sent me on my way. As soon as I drove off the dealership lot on that [XXX] evening, the car lost power and went into limp mode as I accelerated out of the parking lot, and continued through 4 miles of local street traffic until I arrived home and shut off engine. After a few minutes I restarted engine so that I could video record same limp mode issue but the problem was not evident after this engine restart. This was the first episode ever experienced and it occurred at approximately 21,720 miles, and recurred again the following day after stalling from early clutch pedal release, followed by engine restart. The episodes happen on both flat surface and slight incline. The faulty alternator must have a part in this, as surging alternating current is causing sensor malfunctioning affecting a/c fan speed and ECU communication. Autozone alternator test on 4/19/25 revealed charging system failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
