Ford Explorer 2011–2015: Common Problems and What to Check First
Covers 2011–2015 Ford Explorer. Engines: 3.5L V6, 3.5L EcoBoost V6, 2.0L EcoBoost four-cylinder (some years).
Two things come up again and again with this Explorer: a coolant leak that is hard to see, and exhaust smell inside the cabin. Both are worth knowing before they become urgent.
Coolant loss on the 3.5L V6 from the internal water pump
On the 3.5L V6 the water pump sits inside the engine, driven by the timing chain. Owners commonly report that when it leaks, coolant can get into the oil or disappear with no puddle, and that this can lead to serious engine damage if it goes unnoticed.
What you might notice
- Coolant level dropping with no visible leak
- Milky or discolored oil on the dipstick or under the oil cap
- Overheating or a coolant warning
What to check
- Check the coolant level when the engine is fully cold, and check it often if it has been dropping.
- Look at the oil on the dipstick and under the oil filler cap. A milky, light-brown color means coolant may be mixing with it, so stop driving and have it checked.
- Ask a shop to pressure test the cooling system if you keep losing coolant without a visible leak.

Exhaust smell inside the cabin
Owners of this generation have widely reported the smell of exhaust inside the vehicle. It has been investigated by NHTSA. Exhaust leaks, body seals and the way the climate system draws air have all been cited as contributors.
What you might notice
- An exhaust smell inside the cabin, especially under hard acceleration or with the A/C on
- Headache or drowsiness when it happens
- A louder-than-usual exhaust note
What to check
- Treat it seriously, since exhaust contains carbon monoxide. If you smell it, open the windows and have the vehicle checked.
- Look and listen for exhaust leaks, and check that the rear seals and body plugs are intact.
- Ask a Ford dealer whether any recalls or service updates apply to your vehicle. The recall section below shows what NHTSA lists for each model year.
- Consider a carbon monoxide detector made for vehicles if you cannot find the source quickly.
