How to Solve the Auto Start-Stop Malfunction in the Sagitar?
3 Answers
The solutions for the auto start-stop malfunction in the Sagitar are: 1. Check the start system for any faults; 2. Inspect the battery's storage condition and the connection of the terminals; 3. Examine the start wire, fuse, and ignition switch for any damage. Taking the 2018 Sagitar as an example, it belongs to the compact car category, with body dimensions of: length 4753mm, width 1800mm, height 1462mm, wheelbase 2731mm, and a fuel tank capacity of 50 liters. The 2018 Sagitar features a front McPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 116PS, maximum power of 85kW, maximum torque of 175Nm, paired with a 5-speed manual transmission.
I also experienced automatic start-stop issues with my Sagitar, mainly caused by battery aging. When the AGM battery's charge is low after prolonged use, the system automatically deactivates it. You should first check the battery status—look at the voltage indicator on the dashboard; if it's below 12V, recharge or replace it. Additionally, sensors such as an unfastened seatbelt, an unclosed door, or extreme ambient temperatures can also trigger malfunctions. Try these DIY fixes: Turn off the start-stop system when using the AC, or drive on the highway for over ten minutes to recharge the battery. If it still doesn’t work, it might be a software bug—visit a 4S shop for diagnostics and an update. Regular battery maintenance, like replacing it every three years, can prevent this hassle. Until the issue is resolved, be cautious as the engine not restarting when parked can be risky. I often share these tips—keeping the system functioning properly saves fuel.
Automatic start-stop malfunctions can be quite annoying. I suggest starting with simple checks. First, confirm whether the switch button lights up or malfunctions by pressing it a few times. Then, check if the seatbelt is fastened, the doors are closed, and the engine temperature is normal. The battery is a common issue - open the hood and test the voltage or use a multimeter to see if it's below 12V. If possible, take a highway drive to recharge it. Note that the start-stop system deactivates when the AC is on, which is normal. If everything checks out but the problem persists, it might be a faulty relay or control module - don't force it, take it to a professional shop. I've encountered this several times; testing it yourself can often pinpoint the root cause and save you money. Remember to have sensors and wiring checked during maintenance.
