What are the reasons why the GAC GS4's one-button start fails to ignite?

The reasons why the GAC GS4's one-button start fails to ignite are as follows: 1. Battery depletion. Failure to start may be caused by the headlights being left on for a long time or the battery reaching the end of its lifespan, resulting in insufficient power for the one-button start. In this case, simply replace the battery according to the maintenance manual. 2. Out of fuel. If the fuel gauge shows below the red line, the car naturally won't start. Refueling the car will solve this issue. 3. Lack of antifreeze. Some car owners use water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions, leading to engine cracks and preventing the car's water pump from functioning. This not only prevents the car from starting but also damages other engine components. It is recommended to troubleshoot the issue first and then add high-quality antifreeze. 4. Excessive carbon buildup. Too much carbon buildup in the vehicle can also prevent it from starting. Regular cleaning of carbon deposits at a service center is necessary. 5. Spark plug issues. The spark plug is a critical component of the car's ignition system, so its proper functioning directly affects the vehicle's performance and efficiency. If the spark plug has problems, it is advisable to replace it promptly.
I just helped a friend fix the one-button start issue on his Trumpchi GS4, which is quite common. If the car won't start, the first thing to consider is whether the battery is low on charge. When the battery power is insufficient, pressing the button will cause the dashboard to flash but the engine won't turn over. The second possibility is that the key fob battery is dead or there's signal interference. The one-button start system requires the key to be sensed inside the car, and if the key battery is old or affected by electronic interference, it won't work. Third, check if the starter is damaged or rusty, as this can happen if the car hasn't been used for a long time or is in a humid environment. Fourth, it could be a blown fuse—the starter circuit fuse can be found in the fuse box. Fifth, make sure the gear is in Park (P), as the car won't start in Neutral or other positions. The one-button start system relies on multiple sensors, so if multiple attempts fail, don't force it—take it to a professional shop to check the voltage and circuits. For regular maintenance, remember to check the battery and key fob condition to prevent these minor issues and ensure a worry-free driving experience.
I've been driving the GAC GS4 for two years, and last time when I parked on the roadside, the start button didn't respond, which gave me a scare. The first common reason is often that the vehicle has been parked for too long with the headlights or audio left on, draining the battery and preventing startup. The second is to check if it's a key issue, like being placed too far away or having a weak battery that prevents detection. The third is to ensure the foot brake is firmly pressed, as the start button requires simultaneous brake pressing to activate. The fourth could be a starter motor failure, where you might hear clicking sounds but the engine won't ignite. The fifth is weather-related, such as extremely cold temperatures causing oil to solidify and affecting startup. For solutions, first try changing the key's position; if that doesn't work, seek a jump start or check the fuses. While push-button start is convenient, paying attention to small details like turning off electronics when parking and keeping the key in your pocket, along with regular battery maintenance, can save a lot of trouble.
I was very anxious when I encountered the GS4 one-button start failure, which is mostly caused by the battery. If you forget to turn off the lights while parking, the battery will drain quickly, leading to a failed start; weak signals from an aging key battery or interference from nearby mobile phones can also cause failure; if there's a problem with the starter, you might hear unusual noises but no ignition; also check if the gear is in P position and if the fuse is blown. For safety, avoid multiple attempts on the road—first turn on the hazard lights and pull over; try using the mechanical key to open the door, replace the fuse yourself, or jump-start the car. When troubleshooting one-button start issues, start with the simplest checks and stay calm.
