But a bad stop-start system can make you hate the whole concept. I've driven some absolute clunkers. There was the 2016 Cadillac where the stop-start system didn't communicate with the brake-hold Your Engine Control Unit uses signals from the engine sensors to control how the engine runs, when the spark plugs fire to ignite the fuel, and to turn the fuel injection parts on and off at the correct time. If the ECU goes bad due to an internal issue or a power surge, it may stop working or start controlling engine functions at the wrong time. Stop-Start, or Autostop, or ESS, or Idle Stop & Go is a system on a majority of modern cars which cuts the engine off when the car is stationary in order to reduce fuel consumption and emissions. In hybrid vehicles, this system may shut down the combustion engine when the car is cruising at low throttle loads and when descending gradients, as Eco start/stop killed our vehicle’s main battery early. I also can’t help but suspect it’s bad for rings and pistons in the long term, but vehicles with eco start/stop simply haven’t been around long enough to know. They are supposedly wearing out starters as well, even though they’re supposed to be built to withstand extra starts. Many nicer cars with start/stop are mild hybrids which run the AC off a battery (which keeps running when the engine stops). Obviously full hybrids can also run the AC off the battery. more reply.

A replacement starter can cost you between $150 and $400, and the labor costs 100$ to 500$. The starter’s cost also depends on the car model and the availability of the starter on the market. Some starter motors are super-easy to replace, and the procedure can be completed within 10 minutes, while on other car models, it may take several hours. To date, it has received 220 idle-stop complaints. Honda owners are experiencing a number of issues with the system that shuts off the engine instead of idling, and then restarts the engine when the accelerator pedal is pushed down. Now, Honda is looking at a class-action lawsuit related to the idle-stop issue. As long as your key is still in your pocket, the start-stop engine button allows users to get in their car and start the engine without inputting the key. This feature allows the driver to simply press a button to start the car. When you reach your destination, you only need to press the button again to shut down. .
