2021 Ford Explorer Extended Warranty: What 2021 Owners Need to Know
The 2021 Ford Explorer continues the sixth-generation CD6 rear-wheel-drive-based design with 2.3L EcoBoost, 3.3L V6/hybrid, or 3.0L EcoBoost power and a 10-speed automatic. At 50,000–70,000 miles, exhaust leaks and rear differential or bearing issues remain the main repair risks.

2021 Ford Explorer Model Year Overview
The 2021 model builds on the 2020 redesign with a longitudinal-engine, rear-drive-based layout and 10-speed automatic. It is newer than the launch year, but its extensive electronics, hybrid option, and rear driveline still make careful inspection useful as original coverage ends.
Known Issues on the 2021 Ford Explorer
Exhaust Ticking and Exhaust Leaks
Heat-shield or exhaust manifold concerns can produce a ticking noise, smell, or visible leak. Depending on the affected hardware, repairs commonly cost $800–$2,000.
Owner forums, NHTSA complaint descriptions, and technical-service references for sixth-generation Explorers consistently discuss ticking noises and exhaust sealing inspections, including on 2021 examples.
Rear Wheel-Bearing and CV Joint Wear
Humming, vibration, or clicking during turns may trace to rear bearings, CV joints, or driveshaft-related components. Repairs generally range from $900–$2,200.
Rear Differential Fluid Leaks
Leaks should be repaired before low lubricant damages differential internals. Differential resealing or replacement can cost $1,200–$2,500.
