Reasons why the car's one-button start fails to ignite: 1. The car steering wheel is locked: If the steering wheel is turned after the vehicle is turned off, it will be locked. In this case, simply turn the steering wheel left or right while pressing the one-button start. 2. The gear is not in P (Park) position: Due to the system's protection mechanism, an automatic transmission car cannot be started if it is not in the P (Park) position. 3. The car key battery is dead: When the car key battery is dead or low on power, the car's internal sensors cannot detect it, so the vehicle will not start. 4. Some car models require pressing the one-button start twice to start the car, while others require holding the one-button start for a longer duration.

I've encountered the issue of the car's one-button start failing to ignite several times, and there could actually be quite a few reasons behind it. The most common one is a dead battery, either because the car hasn't been driven for too long or because lights were left on, leading to insufficient power to crank the starter. Another issue could be with the key—either the key fob's battery is dead or it's out of the recognition range, as the one-button start relies on it for identification. Additionally, not pressing the brake pedal firmly enough can be a problem; some cars require it to be fully depressed to start, which is easy to overlook. System malfunctions are also common, such as a faulty start button, a blown fuse, or issues with the engine control module. As a temporary fix, you can try jump-starting the car or replacing the key fob's battery. If that doesn't work, it's best to seek professional repair services for a thorough check. For prevention, regularly inspect the battery's condition and the system's health, avoid leaving the car unused for extended periods, and maintain good habits to minimize such troubles.

How often should a family car's vehicle license be inspected?

According to the relevant regulations on motor vehicle annual inspections, small and micro non-operating passenger vehicles are inspected every 6 years; after exceeding 6 years, they are inspected annually; after exceeding 15 years, they are inspected every six months. Since family cars fall under the category of non-operating passenger vehicles, their inspection cycle is every 6 years. During this period, you only need to apply for the annual inspection sticker every two years at the vehicle management office or online. It is only in the 6th year that an on-site inspection is required. Below is supplementary information on the documents required for car annual inspections: 1. "Motor Vehicle Inspection Sticker Application Form" (this does not need to be brought along as it is provided on-site for direct completion). 2. Motor vehicle license. 3. Compulsory traffic insurance certificate. 4. Vehicle and vessel tax payment or tax exemption certificate, which is usually purchased together with compulsory traffic insurance and can be found in the compulsory insurance policy. 5. Owner's ID card; if someone else handles it on behalf of the owner, the representative must bring their own ID card.
