My 2017 Ford Explorer XLT with approximately 236,000 miles has an ongoing EVAP/fuel vapor system problem that causes the vehicle to hesitate, stumble, and attempt to stall. The problem occurs most frequently after refueling and also when the fuel level is low. The check-engine light comes on repeatedly, and despite numerous repair attempts, the issue has not been corrected. Repairs and parts replaced have included the purge valve, EVAP-related sensor(s), charcoal canister(s), and associated tubing. Significant money has been spent diagnosing and repairing this condition, but the symptoms continue. After filling the fuel tank, the engine may run rough, hesitate, lose power, and attempt to stall. This creates a safety concern because the vehicle can unexpectedly lose power or stall while driving, entering traffic, slowing for intersections, or operating in other traffic situations. The condition has persisted despite replacement of multiple EVAP system components. Based on the repeated failures and inability to permanently correct the issue, I believe this may indicate a defect affecting other vehicles of the same model year. I am requesting that this issue be investigated due to the potential safety risk associated with engine hesitation, loss of power, and stalling.

I am reporting a serious safety concern with my 2017 Ford Explorer. The vehicle currently has approximately 93,752 miles and has become increasingly unreliable and unsafe to operate. On April 9, 2026, while my wife was driving home from work, the vehicle overheated, creating a dangerous situation and risk of sudden breakdown. This is especially concerning as the vehicle is used to transport children. Recently, after taking the vehicle in for an oil change, I was informed of multiple additional problems (three separate issues) affecting the vehicle. In addition, the check engine light remains on continuously, even after attempted repairs, indicating unresolved underlying problems. I have also previously attempted to have a recall repair completed, but was told that the necessary part was unavailable and that I would be contacted when it became available. Months later, I have still not been contacted, and the recall issue remains unresolved. Based on my experience and publicly documented issues, this appears consistent with known defects associated with this model, including reported water pump failures leading to engine overheating, rear suspension issues affecting control, and concerns regarding exhaust fumes entering the cabin. This is not normal wear and tear, but a potential safety-related defect. It is a serious concern that known recalls and defects cannot be repaired due to lack of available parts, leaving the vehicle in an unsafe condition. I am also concerned about the risk of continuing to operate this vehicle and potentially causing an accident that could injure myself, my family, or others on the road. This risk is heightened by the lack of timely communication and resolution regarding known defects and recalls. I am requesting investigation into these issues to prevent harm to drivers and passengers
