The start-stop system, standard on many modern Ford vehicles, was intended as the next step towards fuel savings and reduced emissions. In theory, it sounds sensible – the engine automatically shuts off when the vehicle stops at a traffic light, in a traffic jam, or while stationary, and then restarts when the clutch pedal is pressed or the brake is released. The problem is that the theory doesn't quite match up in practice. A growing number of Ford owners are openly admitting that this system is simply irritating. And for good reason.

Why is the start-stop system so troublesome?

Although the idea behind the start-stop system is to minimize fuel consumption and CO₂ emissions, the actual savings are marginal – a few percent in fuel consumption, which in everyday city driving doesn't translate into a noticeable difference in your wallet. However, the system's side effects are clearly noticeable:

• Delayed vehicle response – after stopping and automatically switching off the engine, the reaction to starting again may be delayed, especially in situations requiring quick action, e.g. merging into traffic.
  
• Increased starter wear – frequent switching off and starting of the engine means greater load on the mechanical components.
  
• Cold start – in winter, the system can turn off the engine before it has time to warm up properly, which negatively affects driving comfort and the operation of the drive unit.
  
• No permanent shutdown possible – this is the biggest drawback. Every time the vehicle is started, the system must be manually deactivated again, which is not only tedious but simply impractical.
  

Temporarily disabling the start-stop system in Ford

Ford offers users the option to disable the start-stop system, but crucially, only temporarily. In practice, it works like this:

1. After starting the engine, you should press the physical button, marked with an icon of the letter "A" surrounded by an arrow (usually located in the center of the dashboard).
   
2. The system is turned off while driving – but only until the next engine start.
   
3. When the ignition is switched on again, the start-stop system automatically activates, regardless of previous settings.
   

For drivers who get into their cars and hit the road every day, this ritual becomes a frustrating addition. Many forget to deactivate it, and only the sudden engine shutdown upon the first stop reminds them of the unwanted feature.

• Ford Focus – especially versions from 2015 to 2022. A popular compact car, often used in the city, where start-stop operation is particularly intensive.
  
• Ford Kuga – a mid-size SUV (2016–2023) where drivers often complain about unpredictable engine shutdowns when maneuvering.
  
• Ford Mondeo – (2014–2022) – users who value comfort and smooth driving will find the system unnecessary and aggressive.
  
• Ford Fiesta – especially versions from 2015–2023. A city driving style combined with a small engine causes frequent and noticeable system activations.
  
• Ford Puma – model from 2020. Modern design, but outdated start-stop philosophy.
  
• Ford S-Max and Galaxy – family models (2016–2022), where comfort and smooth driving should be a priority – the start-stop system introduces unnecessary chaos.
