What causes the MG ZS's one-button start to fail to ignite?
2 Answers
If the MG ZS's one-button start fails to ignite, it may be due to a dead smart key battery. After opening the car door, place the smart key in the storage box behind the handbrake, and then you can start the vehicle with one button. Below are some relevant details about the MG ZS: 1. Introduction: The MG ZS is the first internet-connected SUV model under the MG brand, officially launched on March 4, 2017. The MG ZS has been available in over 36 countries and regions, including Australia, the UK, Thailand, India, the Middle East, Brunei, Egypt, Chile, Sri Lanka, and Nepal. Within two years, global sales across four continents reached 250,000 units, and it has repeatedly topped the SUV sales charts in segments such as the UK and Thailand. 2. Performance: As the world's first L2+ autonomous intelligent driving SUV priced at around 90,000 RMB, it is built on SAIC's SSA+SUV architecture platform. It features the leading-in-class Banma Zhixing 3.0 system, the highest-level MG-PILOT L2+ autonomous driving system in its class, and an upgraded 260TGI dual-injection turbocharged engine paired with Aisin's latest-generation 6AT powertrain, achieving a class-leading specific output of 125 horsepower per liter.
When I encounter the issue of the MG ZS not starting with the one-button start, it's usually a battery problem, especially with older vehicles or during cold weather starts, where the battery voltage drops quickly and fails to initiate. Another common cause is insufficient key fob battery, as the one-button start system requires a proper remote signal. If the key's battery is low or placed too far away, the car won't detect it. Additionally, check the fuses and starter relay—if they're burnt out or have poor contact, the ignition system will stall. I recommend first trying to recharge the battery with an external charger. Regular maintenance is key: replace the battery periodically and inspect the wiring. Avoid parking for extended periods in extreme temperatures, as prevention is always better than repair after the fact.
