Quick Verdict
If you are cross-shopping, the 2020 model years that follow it (2022 onward) ironed out most of the launch bugs. The 2020 is the cheapest to buy precisely because buyers know its reputation. That can work in your favor if you do the homework.
Most-Reported 2020 Ford Explorer Problems by Mileage
Here are the patterns that show up most often in owner complaints and shop tickets, roughly in the order they tend to appear. Costs are typical out-of-warranty independent-shop ranges in the US and vary by region and trim.
| Problem | Shows Up | Typical Cost | Severity |
|---|---|---|---|
| Harsh / delayed shifts (10-speed auto) | 0–30k mi | $0–$400 (software / valve body) | Medium |
| Driveline clunk & rear axle concerns | 5k–40k mi | $300–$1,800 | Medium–High |
| Door / trim / wind-noise rattles | 0–25k mi | $100–$600 | Low |
| SYNC 3 / display freezes & reboots | 10k–50k mi | $0–$300 (update / module) | Low |
| Coolant intrusion / turbo cooling (EcoBoost) | 40k–90k mi | $600–$2,500 | High |
| Suspension knock & control-arm wear | 50k–90k mi | $250–$900 | Medium |
| Backup camera / parking sensor faults | 20k–70k mi | $150–$700 | Low–Medium |
Notice the shape of the curve. The expensive failures are the minority. The bulk of 2020 Ford Explorer problems are nuisance-level and software-driven, which is exactly what you expect from a first-year build.
The Big Three Worth Watching
1. Transmission shift behavior
The 10-speed automatic draws the most attention. Owners describe harsh 1-2 upshifts, a hesitation off the line, and a clunk when changing between drive and reverse. In many cases the fix is a powertrain control module reflash that Ford issued through technical service bulletins, not a teardown. Before assuming the worst, confirm the latest calibration is loaded. If the unit still bangs into gear after that, you may be looking at valve body work in the $800 to $1,800 range. If you see a stored shift-related code, our guide on a slipping or harsh-shifting transmission walks through what is software versus hardware.
2. Driveline and rear axle
Because the 2020 Explorer moved to a rear-drive architecture, the driveshaft, rear differential, and axle hardware are new territory. A subset of early builds generated complaints about clunks, vibration, and in rare cases rear axle bolt or driveshaft concerns. This is the area most worth inspecting on a test drive: accelerate, decelerate, and reverse on an incline and listen for repeating clunks.
3. EcoBoost cooling and coolant intrusion
Both the 2.3L and 3.0L EcoBoost engines run turbochargers that demand healthy cooling. As these trucks cross 50,000 to 90,000 miles, watch for coolant loss with no visible external leak, which can point to internal intrusion. If your dash lights up, start with a code scan. A P0128 coolant thermostat code or a P0299 turbo underboost code are both worth taking seriously on this platform.
Common Mistakes Buyers and Owners Make
- Skipping the recall check. The 2020 Explorer was subject to multiple recall campaigns during its life. Always run the VIN on the official NHTSA or Ford recall lookup and confirm every open campaign has been completed before money changes hands.
- Paying for a transmission they did not need. Plenty of harsh-shift complaints were resolved by a free software update. Do not let a shop quote you a $4,000 transmission before the latest calibration has been verified.
- Ignoring slow coolant loss. A half-inch drop in the reservoir every month is not normal. On a turbocharged EcoBoost, small coolant loss can become a head or turbo bill if ignored.
- Buying without records. A 2020 with a clean, documented service history behaves very differently from a neglected one. The drivetrain can run 150,000 to 200,000 miles, but only if maintenance was not deferred.
- Trusting a single quote. Repair estimates on these vary wildly. Run any number you get through our repair quote checker before you approve work.
Is It a Dealbreaker? A Quick Framework
Use this to decide whether a specific 2020 Ford Explorer problem is a walk-away or a negotiate-and-fix.
| Symptom | Verdict | Action |
|---|---|---|
| Harsh shifts, no codes | Not a dealbreaker | Verify latest software first |
| Repeating driveline clunk | Investigate before buying | Lift inspection, check axle hardware |
| Unexplained coolant loss | Potential dealbreaker | Pressure test, walk if no records |
| Infotainment freezes | Not a dealbreaker | Update SYNC, low priority |
| Open uncompleted recall | Conditional | Make seller close it first |
The rule of thumb: software and trim complaints are bargaining chips, not red flags. Driveline noise and coolant loss are the two areas where you slow down, inspect hard, and price the risk in.
FAQ
TL;DR
The 2020 Ford Explorer has known issues driven by its first-year redesign. Most are nuisance-level: harsh shifts cured by software, infotainment freezes, and trim rattles. The two areas that deserve real caution are driveline noise and unexplained coolant loss. Buy one with documented service history and closed recalls, verify the transmission calibration, and you can land a capable three-row SUV for thousands less than newer years. Buy one blind and you inherit someone else's deferred maintenance.
