Ford models are known for their durability, but, like any car, they’re not immune to common engine issues. Popular models like the Ford Focus, Fiesta, Mustang, and Explorer, as well as trucks and vans like the Ford F-150 and Transit, can suffer from water pump problems and coolant leaks. Left unchecked, these issues can lead to overheating, white smoke from the exhaust, or even a blown head gasket.
Below, we’ve compiled a list of the most commonly reported issues with a variety of Ford models.
Common problems for Ford Models
1. Coolant Leaks
Coolant leaks are common in Ford vehicles, especially those with EcoBoost engines like the Focus, Fiesta, and Explorer. These leaks often stem from the water pump or head gasket, leading to overheating or white smoke from the exhaust. If your coolant levels drop rapidly, it’s likely a leak that, left unchecked, could cause costly engine damage.
Symptoms to Watch For
- White smoke from the exhaust (especially in EcoBoost engines)
- Rapidly dropping coolant levels
- Overheating engine
Models Most Affected
- Ford Focus (especially 2.3-litre EcoBoost models)
- Ford Fiesta
- Ford Explorer
How to Fix It
K-Seal offers a quick fix by sealing cracks or holes in the coolant system, preventing overheating.
For 2016–17 Ford Focus models with 2.3-litre EcoBoost engines, Ford provides free inspections and repairs due to head gasket sealing issues, so take advantage of this service if needed.
2. Transmission Issues
Transmission problems are another common complaint in several Ford models. Issues can include lethargic transmission, rough shifting, slipping gears and even complete transmission failure.
Symptoms to Watch For
- Difficulty shifting gears
- Grinding noises during acceleration
- Slipping or unresponsive gears
Models Most Affected
Common amongst most models but particularly susceptible models include:
- Ford Fiesta (automatic transmission models)
- Ford Focus
- Ford F-150
How to Fix It
Routine maintenance, including transmission fluid changes, can help reduce these issues. For severe problems, we advise consulting a professional mechanic.
3. Electrical System Failures
Ford vehicles like the Edge and Mondeo are prone to electrical system failures. These can include malfunctioning sensors and issues with power steering, navigation systems or dashboard error lights.
Symptoms to Watch For
- Inconsistent operation of power windows or locks
- Faulty dashboard warning lights
- Problems with sensors, such as the parking assist or fuel gauge
- Problems with power steering
- Issues with engine management system
- Faulty infotainment and navigation systems
Models Most Affected
- Ford Edge
- Ford Mondeo
- Ford Focus
- Ford Fiesta
- Ford Mustang
How to Fix It
Consult a professional mechanic who will inspect and replace faulty wiring or sensors. Regular diagnostics can identify and prevent electrical failures early.
4. Water Pump Failures
Problematic water pumps can be a feature of many Ford models, including the Fiesta, Focus, Transit, and Explorer. This causes water to leak into the footwells of some cars, resulting in dampness. The greater risk of this, however, is that a water pump leak in a Ford could prevent your coolant circulating freely through your engine, and result in it overheating and severe engine damage if not addressed.
Symptoms to Watch For
- Coolant pooling under the car
- Overheating engine
- Squealing noises from the engine
Models Most Affected
- Ford Fiesta
- Ford Focus
- Ford Explorer
- Ford Transit
How to Fix It
Regularly monitor coolant levels and replace the water pump if needed. Using K-Seal can provide a fix for minor leaks.
5. Suspension Problems
Some Ford models, like the Focus and Explorer, are known for suspension issues, including excessive bouncing, drifting or pulling.
Symptoms to Watch For
- Uneven tyre wear
- Clunking noises when driving over bumps
- Difficulty steering
- Vibrations felt through the steering wheel at high speeds or braking
Models Most Affected
- Ford Focus
- Ford Mondeo
- Ford Explorer
How to Fix It
Have a professional mechanic inspect suspension components regularly and replace worn parts like shocks, struts, or control arms.
6. Engine Problems
Engine problems such as stalling or excessive oil consumption are common problems in models like the Ford Focus and EcoSport. This can result from a range of issues, including fuel delivery problems or faulty sensors.
Symptoms to Watch For
- Sudden loss of power while driving
- Difficulty starting the engine
- Irregular idling
Models Most Affected
- Ford EcoSport
- Ford Focus
- Ford Mustang
How to Fix It
Ensure your fuel system, filter, and sensors are regularly inspected and maintained. We recommend consulting a professional mechanic for further advice.
7. Brake Issues
Owners of Ford models like the Mustang and F-150 often report brake-related problems, including premature wear or failure of brake components.
Symptoms to Watch For
- Squealing or grinding noises when braking
- Increased stopping distances
- Brake pedal feels spongy/soft
Models Most Affected
- Ford Explorer
- Ford Mustang
- Ford F-150
- Ford Edge
- Ford Escape
How to Fix It
Replace worn brake pads and rotors as needed, and check for leaks in the brake lines.
8. Spark Plug Issues
Spark plug problems are another common issue in Ford vehicles, particularly in models like the Ford Explorer and F-150. Faulty or worn-out spark plugs can lead to poor engine performance, difficulty starting, or even misfires. Some users even reported spark plugs ejecting themselves from the engine.
Symptoms to Watch For
- Difficulty starting the engine
- Reduced fuel efficiency
- Engine misfires or rough idling
Models Most Affected
- Ford Explorer
- Ford F-150
How to Fix It
Regularly inspect and replace spark plugs as part of your vehicle’s maintenance schedule. Using high-quality spark plugs can help improve ignition efficiency and prolong engine life.
