The concept of the stop-start system is simple. It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake (or puts in the clutch to select 1st gear) to get going again.
Do cars shut off automatically?
A vehicle start-stop system or stop-start system automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions. ...

Then your engine might not receive enough air, which it needs to power itself. When there's a lack of air, it leads to a lack of power, which can cause your car to stall while idling.
What makes a car shut off while running?
A lack of fuel pressure or fuel volume can easily lead to engine stalling. Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel.
Why would a car shut off while stopped?
If the torque converter is broken, or if there is a low fluid level in the transmission, the converter will not do its job, and the car will be unable to maintain power at low speeds, which causes the engine to shut off. A defective TCS or torque converter solenoid can also cause this issue.
Do all new cars shut off when stopped?
Here is the good news: almost every vehicle I drive that has start/stop also has a switch to turn the system off, but some GM SUVs recently did not have a way to disable it. ... The bad news is that in almost all cases, you have to disengage the system every time you start your vehicle.
Does auto stop really save gas?
Most people think the amount of fuel saved using a start-stop system is negligible, but in reality, that fuel burned while idling at a stop adds up quickly. A study by the Society of Automotive Engineers found that using start-stop can see a car's fuel economy improve by over eight percent in heavy traffic.
Why do new cars smell so good?
