I have voted for a no and that broadly seems to be the consensus here and I agree with everyone on the point of: 1. Engine wear and starter motor life being a concern. 2. A/C compressor switches off each time. 3. Pain to switch the feature off every time we start the car. After all of this, it starts to become a pain rather than an added feature. Manufacturers do guarantee that cars with stop-start fitted will suffer no reliability gripes for their foreseen active duties. Cars with start-stop get upgraded alternators, starters and batteries, but these don’t have anything to do with internal wear, they just increase the ruggedness of said components (which may be used even 10x more often than in a car with no stop-start) and that’s The system monitors a lot of variables about the car, such as engine temperature, climate, 12V battery charge, etc. If one of these system require more charge, the engine gets started. However, for me it can last for 2-4 minutes most of the time, enough for the average red light duration. 1. r/mazda3. The bottom line is that stop-start accumulators must be handled properly in order to avoid injury. In all cases, it should be considered a requirement, not just a suggestion, to read and fully understand the appropriate service manual procedures for safe removal, discharge and handling of these units. Furthermore, it’s imperative to respect Ignition System Problems: The 3 core elements for the car to start and run are fuel, spark, and air. If these three elements are available in the correct ratio, then the car will run smoothly and will not stop. If one of the three elements fails to decrease or increases slightly, the ratio changes and the car will not have a smooth running. Check other engine and chassis grounds as necessary. 6. Why It's Important to Find and Fix Bad Grounds. Bad engine grounds can ultimately prevent the battery from charging properly, prevent the car computer from getting the correct signals, prevent the headlights from illuminating properly or at all and cause hard-starting issues and other faults. Many vehicles these days have start/stop without an E-Torque like system, however they have heavy duty starters, AGM deeper cycle type batteries and in cases like Fords Ecoboost, an upper valve-train designed to hold oil longer. Which is why you need to wait at least 15 minutes just to check the oil on those engines. As J.D. Power explains, the act of running your engine without moving doesn’t use too much fuel. However, it still drains that battery and continuously warms the engine. Fortunately, as long as your car is maintained correctly, you don’t have to worry about damaging the drivetrain. For example, if your engine is continuously running on a .
