Shortly after purchase of the vehicle on November 26, 2021, the vehicle began experiencing repeated DEF (Diesel Exhaust Fluid), SCR, and DPF system failures, accompanied by dashboard warning indicators, drivability instability, reduced power warnings, and eventual shutdown conditions. The most serious safety concern is that when the DEF/emissions warning activates, the vehicle may enter reduced-power mode and ultimately become non-operable, creating a significant roadway safety hazard. The vehicle has repeatedly experienced conditions where it could lose power, become unreliable in traffic, or shut down unexpectedly after emissions-related warnings appeared. The vehicle required repeated repair attempts beginning almost immediately after delivery, including diagnostics and repairs involving: DEF system malfunction SCR/DPF restriction codes Reduced power warnings Fuel pressure-related faults Emissions-system failures Drivability instability Suspension-related concerns Despite multiple repair attempts by authorized facilities and warranty-related interventions, the same categories of failures continued to recur. This condition creates a serious safety concern because the vehicle can become unreliable or effectively inoperable while being driven, particularly after activation of emissions-related warning systems. The repeated loss-of-power and shutdown-related behavior creates risk during normal roadway operation. I am requesting review of the recurring emissions-system failure pattern, drivability instability, and operational shutdown behavior associated with this vehicle.
