Does the Start-Stop Disabler Harm the Car?
4 Answers
Start-stop disablers do not cause significant harm to cars. Here are the relevant details: 1. Principle: Most wear and tear on a car engine comes from the instantaneous wear during cold starts. Since automatic start-stop durations are very short, the oil adhering to the inner surfaces of the engine cylinders does not completely drain away. Under hot start conditions, the impact on the engine is minimal. 2. Automatic Start-Stop: Engine automatic start-stop refers to a system that automatically shuts off the engine when the vehicle temporarily stops during driving (e.g., at a red light) and automatically restarts it when it's time to move forward again.
I've been using an auto start-stop deactivator for several years. As an experienced driver, I don't think it actually harms the car much. The start-stop system is designed to be quite durable, with manufacturers considering frequent starts—the starter battery is reinforced. But with the deactivator installed, it reduces the number of engine restarts each time you stop and start, which actually prevents premature wear on the starter battery and starter motor. Fuel consumption might be slightly higher since the engine stops less often, saving a bit on fuel costs. However, from a hardware perspective, the engine runs smoothly, and I've checked the temperature sensors with no abnormalities. If you're considering installing one, just make sure to get a proper device and avoid tampering with the wiring. Overall, my car hasn't had any issues, and turning off the start-stop actually makes driving smoother.
I drive to work every day for my commute, and it's much more comfortable after installing an auto start-stop deactivator in my car. The auto start-stop would always shut off and restart the engine in traffic, causing the car to jerk around. After turning it off, the engine runs continuously, reducing the load on the starter and preventing the battery from frequent charging. Fuel consumption did increase a bit, costing me a few hundred dollars more in gas per year, but I don't feel it causes any damage to the car itself. The engine temperature stays stable, and the ride is smooth. I consulted a mechanic, and he said this is just a software-level adjustment that doesn't interfere with the core hardware. For a cautious driver like me, deactivating the auto start-stop to extend component lifespan is a good thing. Of course, don't tinker with it yourself—just have it installed professionally.
As a new car owner, I directly installed an auto start-stop disable app and easily solved the problem. That start-stop function is so annoying - it shuts off the engine at every red light, and the vibration during restart is noisy. After turning it off, there's no more power interruption feeling, and the power delivery becomes smoother. The car's hardware isn't affected - the engine still runs normally, and the battery hasn't failed prematurely. In car owner groups, many say start-stop deactivators save future maintenance hassles and don't harm the vehicle. I don't mind slightly higher fuel consumption - comfort is what matters most. It's an easy adjustment to make, no need to over-worry about potential vehicle damage.
