With very tightly controlled fuel injection the old wisdom is no longer true. A running engine burns more gas than one that is not running and a "warm" start doesn't involve the wear that a cold start does. The starter is beefed up to handle the increased number of cycles, though naturally it will cost more to replace when the time comes.
The Ford F-150 auto start-stop feature is a fuel-saving technology that turns off the engine when the vehicle comes to a complete stop and restarts it when the driver releases the brake pedal. However, this feature has been known to experience a number of problems, including stalling, rough idling, slow restart, and premature battery wear.
Yep, I tolerate it on my hybrid daily driver because it's just the way it is with hybrids, and unlike the Pentastar, the hybrid's gas engine is actually specifically designed for frequent stop/starts without causing excess wear and tear - also it's less annoying because the electric motor drives the car forward without any delay even before the gas engine has kicked back on, and there's zero
1. Weak Battery. If your Compass engine won’t crank or cranks very slowly, then the most likely culprit is weak or dead 12v battery. Investigating more closely and doing a battery voltage test will clarify whether the starting problem is due to the battery. A test can be done to measure the voltage between the battery poles, check the acid
3. The Engine Has Been Idling Rough. A rough idle can also be a sign of an engine misfire or a problem in the engine that will soon cause a serious misfire. This rough idle is often due to minor fuel/air ratio deviations caused by sensor problems, compression issues, or a minor leak in the intake manifold gasket.
