P0300 on a Ford Escape
Random/Multiple Cylinder Misfire Detected
1.6L and 2.0L EcoBoost turbo fours (2013+), the 2.5L Duratec, and the older 3.0L Duratec V6.
What P0300 usually means on a Escape
P0300 is a random or multi-cylinder misfire, and on the Escape the most consequential version is on the 1.6L EcoBoost, where coolant intrusion into the cylinders was a known problem that could cause misfires and even overheating fires that prompted recalls. On the naturally aspirated 2.5L and 3.0L engines the causes are more ordinary: aging coils, plugs, and vacuum leaks. Sorting out which engine you have and whether the misfire tracks with temperature or load is the first diagnostic step. A misfire that comes with coolant loss on a 1.6L EcoBoost is one to take seriously and address quickly.
Most likely causes on this model
- Coolant intrusion / head issues (1.6L EcoBoost)
The 1.6L EcoBoost had documented coolant-loss and cylinder-head problems that can foul or hydrolock cylinders and set misfire codes. On this engine a P0300 with disappearing coolant is a red flag, not a routine tune-up.
- Worn ignition coils and spark plugs
Across all Escape engines, tired coils and plugs are the everyday random-misfire cause. Boots crack and plugs wear, producing a misfire that wanders under load.
- Vacuum or PCV leak
A cracked PCV hose or intake gasket leans multiple cylinders at once, a common P0300 source on the Duratec engines as they age.
- Carbon buildup on intake valves (EcoBoost)
Direct injection lets carbon accumulate on the valves, disturbing airflow and causing rough running and misfires at higher mileage.
- Fuel delivery weakness
A weak fuel pump or dirty injectors can starve several cylinders, especially under acceleration, on higher-mileage Escapes.
What it costs on a Escape
On the naturally aspirated engines a set of coils and plugs is an affordable, DIY-friendly repair. The 1.6L EcoBoost is the expensive scenario: if the misfire stems from coolant intrusion and head damage, you are looking at major engine work, so confirm whether coolant is disappearing before spending on ignition parts. Recall coverage may apply to certain 1.6L EcoBoost Escapes, so it is worth checking the VIN with Ford.
Fixing it
Identify your engine first. On a 2.5L or 3.0L, start with coils, plugs, and a vacuum-leak check. On a 1.6L EcoBoost, check coolant level and history before anything else, and have any open recalls verified by VIN.

Escape owners also ask
Is a misfire on my 1.6L EcoBoost Escape dangerous?
It can be. That engine had documented coolant-intrusion and overheating problems that led to recalls, and a misfire combined with unexplained coolant loss should be inspected promptly rather than just treated as worn plugs. Check your VIN for open recalls with Ford.
Can I fix P0300 on my 2.5 Escape myself?
Often yes. On the naturally aspirated engines the common causes are worn plugs, failing coils, and vacuum leaks, all of which are accessible and reasonably priced. Rule those out before assuming anything internal.
