NHTSA complaint #11746273

Owner complaint summary

Vehicle: 2023 Ford Explorer ST VIN: [XXX] I am reporting ongoing safety-related powertrain and drivability defects that continue despite numerous repair attempts, including complete engine and transmission replacement. Since approximately June 2025, my vehicle has experienced delayed acceleration, hesitation, erratic RPM behavior, harsh shifting, loss of power, and intermittent warning lights. The vehicle has also stalled, jerked during acceleration, and exhibited transmission shuddering and lurching. The problems have been repeatedly reproduced, documented, inspected, and repaired by Kendall Ford of Anchorage, Alaska, the sole servicing Ford dealership involved. Repairs have included replacement of fuel injectors, cylinder heads, a complete engine assembly, and a complete transmission assembly. Despite these repairs, the safety concerns remain. Current symptoms include: • 1-4 second delay in throttle response. • Vehicle may fail to accelerate below approximately 30 mph. • Engine RPM rises significantly without proportional vehicle acceleration. • Erratic shifting, surging, and harsh jolts. • Intermittent check engine lights, FordPass alerts, and electrical warnings. These conditions create a significant safety risk because the vehicle may fail to accelerate when entering the highway, merging into traffic, crossing traffic, making left turns, or avoiding hazards. The delayed throttle response and sudden acceleration after the delay increase the risk of a crash. Attached service records document stalling, misfires, loss of propulsion concerns, and repeated powertrain failures requiring replacement of both the engine and transmission, yet the drivability concerns continue. I believe this may involve a defect in the powertrain, transmission controls, engine management system, electronic throttle control system, or related vehicle control modules. I respectfully request that NHTSA investigate these recurring safety-related defects. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
