What are the reasons for the automatic shutdown of Tiggo 5?
2 Answers
1. Battery issues: Due to the end of the battery's service life, the battery capacity and output voltage decrease, which can directly lead to abnormal starter operation, low voltage, and the engine spark plug failing to generate sparks. In severe cases, the engine may shut down and experience difficulty starting. 2. Vehicle high-voltage circuit failure: After ruling out the issues mentioned in point 1, priority should be given to checking whether the high-voltage circuit has problems such as aging, detachment, short circuit, or open circuit. 3. Engine fuel supply blockage: Abnormal fuel supply can cause interruption of the engine stroke, or severe carbon deposits or erosion in the cylinder spark plug, leading to unstable sparks and difficulty in engine starting. The engine may also shut down abnormally when the throttle changes.
That day, while driving my Tiggo 5 home with the kids, it suddenly stalled, which was quite frightening. The mechanic later said fuel system issues are the most common, like a burned-out fuel pump cutting off supply or clogged fuel injectors preventing spray, starving the engine. A gasoline filter left unchanged for too long can also easily clog, and low-quality fuel from gas stations can damage the entire fuel system. Additionally, problems in the ignition system, such as eroded spark plugs or cracked ignition coils, are particularly prone to act up in rainy weather. Lastly, minor issues like loose battery terminals can be the most dangerous, causing the car to lose power and stall while driving. Now, during every maintenance check, I make sure to have these components inspected.
