NHTSA Complaint #11715348 — 2018 FORD ECOSPORT

The affected systems are the engine and powertrain. After completion of Safety Recall 23S64 (NHTSA #23V905) in November 2025, my vehicle began experiencing repeated loss of power, stalling, and reduced-power “limp mode” events. The check engine light illuminated and diagnostic trouble code P0299 (Turbocharger Underboost Condition) was identified. The vehicle remains available for inspection upon request. My safety and the safety of others were put at risk due to sudden loss of engine power while driving, including hesitation and reduced acceleration in traffic. The vehicle has stalled and entered limp mode unexpectedly, creating a risk of being unable to maintain speed or safely merge. The problem has been reproduced and documented through multiple return visits to the same Ford dealership following the recall repair. The dealership attempted repairs including spark plug replacement and battery replacement, which did not resolve the issue. On the most recent visit, the dealership stated the issue was “unable to duplicate” and returned the vehicle without repair, despite prior documented limp mode behavior. The vehicle has been inspected by the manufacturer’s authorized dealership multiple times. Additionally, an independent diagnostic scan confirmed P0299 turbocharger underboost. Warning indicators included the check engine light, reduced engine power, and limp mode behavior, which first appeared after the recall repair was completed. These symptoms have continued despite repeated service visits. Given the vehicle’s history of prior engine failure at approximately 29, 313 miles, and the fact that Recall 23S64 involves oil pump belt failure and oil pressure loss, I am concerned that the recall repair was incomplete or ineffective, potentially allowing residual oil starvation damage affecting the turbocharger and related components.
