2018 Ford Explorer Extended Warranty: What 2018 Owners Need to Know
The 2018 Ford Explorer remains on the fifth-generation unibody AWD platform, using the 3.5L V6 or 2.3L/3.5L EcoBoost engines with a 6-speed automatic. At 85,000–105,000 miles in 2026, the costly concerns are PTU deterioration and transmission shudder or failure.

2018 Ford Explorer Model Year Overview
As a mature fifth-generation model, the 2018 Explorer shares the transverse-engine architecture used since 2011. Its 6-speed automatic and optional turbo engines provide strong performance, but aging examples need careful attention to driveline fluid condition and shift quality.
Known Issues on the 2018 Ford Explorer
Power Transfer Unit Fluid Breakdown
Heat and old fluid can damage the AWD PTU, leading to leaks, odor, or grinding. Repairing or replacing the unit generally costs $1,500–$2,800.
Explorer owner-forum threads, TSB discussions, and NHTSA-style complaints repeatedly identify PTU heat and fluid condition as notable fifth-generation AWD concerns on higher-mileage vehicles.
6-Speed Transmission Shudder or Failure
Harsh shifts, slipping, and shudder can worsen into an internal 6F35/6F50 transmission failure. A rebuild or replacement commonly totals $3,500–$6,500.
EcoBoost Turbocharger Wear
On turbo models, loss of power or abnormal boost noise can signal worn turbo components. Typical turbocharger repairs run $1,800–$3,500.
