Fourteen complaints on 2023 Tundra fuel systems break into two camps: those with active failures and those stalled by parts unavailability on recall 23V566000.
The serious one: a driver experienced smoke, then a fuel tank fire on the driver's side at 63,000 miles. Fire Department extinguished it; the truck was totaled. At the time of complaint, recall parts still weren't available.
Others reported fuel smell accompanied by condensation under the passenger seat (30K miles), and a fuel gauge that gave wrong readings—both at the pump and while driving—with no diagnosis after dealer visits.
The larger problem: nine separate owners received recall notifications for 23V566000 (Fuel System, Gasoline) but couldn't get parts fixed. Some dealers ordered parts, then told owners the parts were sold before appointments could be scheduled. One owner was offered an interim repair—protective materials and a clamp on the fuel tube—but the dealer couldn't perform it either. Toyota sent an engineer to investigate one vehicle but found no defects to report. Owners consistently said Toyota exceeded a reasonable timeframe for the recall remedy.
