created a serious rear-end collision risk. This is my [[redacted]] daughter's daily driver, and I am concerned about a novice driver experiencing the same failure. An immediate independent diagnostic scan showed P33ED-00 (HV Battery Parallel Diagnosis), P3180-97 and P317E-97. Battery telemetry showed SOH 88.51% and Hx 57.24%. I request investigation into whether a battery defect and/or the recall software caused this highway propulsion loss. These readings have not yet been evaluated by a Nissan dealer. On [redacted], Nissan Consumer Affairs/Roadside Assistance agents and supervisors refused complimentary towing from our residence, stating they would not accept third-party diagnostics and required dealer evaluation first. We were told to pay for towing or arrange transport ourselves. The vehicle remains at home with unresolved battery safety concerns. My daughter has lost her transportation; rental/loaner age restrictions prevent her from using a replacement. We still owe $12,158.09 on a vehicle that can not be driven because of a safety recall. I request NHTSA investigate the propulsion failure, adequacy of the R24B2 remedy and Nissan's refusal of towing assistance. I request Nissan provide safe flatbed transport, a permanent remedy and a vehicle buyback resolving the outstanding financing. Diagnostic records and recall service documentation are available.
