Push-to-start seems easy — but here are the hidden risks drivers forget

Engine start buttons, or “push-to-start” systems, are becoming standard in modern cars. Sleek, convenient, and futuristic — but are they truly safer than old-fashioned keys?

While convenient, these systems can create serious safety risks, especially when drivers assume the car is off — when it’s not. In some cases, this has led to fatal accidents involving carbon monoxide poisoning inside garages.

According to this report published by Pravda.ru, cases in the U.S. and Europe show that failing to shut off the engine properly can go unnoticed, since the system is silent and lacks the tactile feedback of a key.

Common mistakes with Start/Stop buttons

Myths about the engine start button

• Myth: Push buttons are always safer than keys
  Fact: In emergencies, they may be harder to shut off
• Myth: If it started, it’s fine
  Fact: Auto-start systems can malfunction without warning

FAQ — common driver concerns

• Do I have to press the brake to start? Yes — that’s part of the safety lockout
• What happens if I walk away with the key? The engine may keep running — but you can’t restart it later
• Is there a way to shut off the engine fast? Yes — holding the button for 3 seconds forces shutdown

In the U.S., dozens of deaths have been reported due to carbon monoxide exposure after drivers left push-start cars running in garages. Without the traditional “key-off click,” drivers often assume the engine is off — but it’s not.

Push buttons offer convenience, but demand awareness. Knowing how they work could save your life — or someone else’s.
