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.
