Generally, the car cannot be turned off due to a circuit failure and needs to be repaired at a maintenance station. The specific reason is that the engine computer is still working when the ignition key is turned off, and the power supply comes through other circuits. It may be due to a short circuit to the ground or the live wire, or it may be that the PCM relay is continuously conducting due to mechanical reasons. The following is extended information: The significance of the one-button start device: The one-button start device can be said to be one of the current intelligent car components. It is mainly a button device that realizes a simple start process, and it can also realize one-button shutdown. The device can be modified at the original car key lock position or set to be modified by an independent panel.

Once when I was driving my Luxgen U6, the car suddenly wouldn’t turn off, which gave me quite a scare. Later, after checking, the issue was likely with the ignition switch—possibly due to excessive dust or contact wear, causing the system to mistakenly think it was still in the starting state. Problems with the key remote could also be the culprit, such as a dead battery or signal interference, especially in urban high-rise areas. Another common cause is a fault in the Electronic Control Unit (ECU), perhaps due to a software bug or hardware aging, which can make the engine ignore commands. I quickly disconnected the battery manually for emergency handling before heading to the repair shop to replace the parts. The mechanic also mentioned that this is related to routine maintenance—if you rarely drive on highways or don’t regularly check the electrical system, such issues are more likely to occur. In short, this problem should be addressed early to avoid excessive fuel consumption or potential accidents.

As a technician who frequently repairs Luxgen vehicles, I've encountered numerous cases of difficulty shutting down the engine. In eight or nine out of ten cases, it's due to a stuck ignition relay, which could be caused by poor contacts or oil accumulation. Faults in the key recognition system are also common, especially during humid seasons when sensors may fail or misjudge. Additionally, unstable battery voltage can disrupt the control unit, preventing the car from shutting down properly. Less common reasons include the transmission not being fully engaged in park or abnormal ECU programming. I recommend first disconnecting the negative battery terminal for a few minutes to force shutdown, then inspecting the relay and key system. Regular maintenance of the fuel injection system can prevent these issues. After all, Luxgen vehicles come with numerous electronic configurations that can easily cause trouble if not properly maintained - early repairs mean less hassle later.

It's really dangerous when the car won't shut off. I've personally witnessed it causing small fires. The reason could be a malfunction in the fuel system, such as the pump continuously supplying fuel, or a short circuit in the ignition module. Safety first: pull over immediately, turn off all electrical devices, and manually disconnect the battery cables. If left unaddressed, it can accelerate part wear or pose a fire risk. Preventive measures include regular maintenance of the electrical system, especially for high-spec cars like Luxgen, ensuring there are no unauthorized wiring modifications. This is not something to delay.
