What are the reasons for the GAC GS4's one-button start failing to ignite?
3 Answers
GAC GS4's one-button start failing to ignite may be due to the following reasons: 1. Insufficient fuel: If the fuel gauge shows below the red line, it naturally won't start. 2. Dead battery: This could be caused by leaving headlights on for a long time or the battery reaching the end of its lifespan, leading to failure to start. It is generally recommended to replace the battery every 2 years. 3. Circuit malfunction: Installing xenon headlights, high-power speakers, DVD players, etc., can cause vehicle circuit malfunctions, resulting in no power and failure to start. 4. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) when starting. If it's in R (Reverse) or D (Drive), the engine won't start.
Last time I drove a Trumpchi GS4, I also encountered the issue where the one-button start wouldn't ignite the engine. It's quite annoying. The most common cause is usually a dead battery, especially after prolonged parking, where battery aging or leakage leads to insufficient power. The one-button start system relies on smart key sensing. If the key battery is nearly depleted or the sensing signal is interfered with—for example, by a strong magnetic field nearby—the system won't recognize it. Another possibility is poor contact with the button itself, where pressing it multiple times yields no response. There could also be issues with the starter or fuel pump, or a clogged fuel filter preventing the engine from drawing fuel. When troubleshooting, I start with simple steps: try a spare key or manually insert the car key into the ignition slot. If there's still no response, measure the battery voltage—if it's below 12 volts, recharge or replace it. Regular maintenance and avoiding long-term vehicle inactivity can help prevent such issues. The one-button start system is intricately designed, so never attempt disassembly yourself. It's safer and more reliable to get a professional diagnosis at an authorized repair shop, especially since it involves engine startup—something you can't afford to take lightly.
I've been driving the Trumpchi GS4 for several years, and when the one-touch start fails, the first thing that comes to mind is the smart key issue. Insufficient key battery or signal loss is the most common problem—keeping it in your pocket for too long can drain the battery, and replacing the coin cell usually fixes it. However, sometimes it's due to the vehicle's own low battery, like difficulty starting in cold winter mornings or forgetting to turn off the lights and draining the battery. Poor contact in the one-touch start button's wiring can also be a cause—if pressing the button gives no feedback, dust might have gotten inside. It's also worth checking if the anti-theft system was accidentally triggered, such as by some foreign object in the car setting off the alarm. I usually make a habit of checking the dashboard indicators before driving, like the fuel gauge showing low levels, which can also prevent the car from starting. A temporary fix is waiting a few minutes and restarting or trying a spare key, but for long-term prevention, it's best to regularly check the battery and clean the button. The one-touch start is convenient, but minor issues should be addressed promptly to avoid being stranded on the road, which is too dangerous. I recommend getting a free diagnostic check at a 4S shop—their computer scans for fault codes are very accurate.
