What are the reasons why the car USB suddenly cannot play music?

Here are the reasons why the car USB suddenly cannot play music: 1. Damaged song files: Corrupted music files may suddenly cause the music on the USB to stop playing. 2. USB malfunction: The USB may have bad sectors or partially damaged files. Test the USB on a computer to see if it can play. If the songs on the USB play normally on the computer, then the issue might be the incorrect file format. The car can only read MP3 format song files, preferably at 128KB, and does not support other formats. Solution: Re-download songs in the correct format or use a format conversion tool to change the format. Some music formats are not recognized by car players, but generally, MP3 and WAV formats are supported. 3. Loose connection between the USB and the USB port: Since the USB is plugged into the car's USB port for a long time, the vibration and shaking of the vehicle while driving may cause the connection to loosen. If the USB is loose, it may result in the music suddenly stopping.

As a car owner, I've encountered several instances where the car USB suddenly stopped working. The most common reason is an issue with the USB drive itself, such as oxidized contacts or corrupted files causing data read interruptions. Another possibility is poor contact or dust accumulation in the USB port, leading to loose connections and no signal. Sometimes, the car system only recognizes FAT32 format, making NTFS-formatted USBs completely ineffective. The music file format also matters—MP3 is the safest, while other formats might be ignored by the system. If the USB is nearly full with too many files, it can cause lag or fail to start playback. Solutions: First, unplug the USB, clean the port, and try again; if that doesn’t work, test another USB or check if a computer can recognize it. If not, reformat it to FAT32 and reload the music. To prevent aging, avoid leaving the USB plugged in for long periods in a hot car. Most issues can be resolved with simple steps, so there's no need to rush for repairs.

From a technical perspective, I'm quite familiar with the reasons for in-car USB drive failures. Internal circuit issues like damaged flash memory chips can cause complete playback failure, or insufficient power supply from the USB port may lead to data transfer interruptions. Compatibility is crucial: car stereos typically only support specific file systems like FAT or exFAT, while NTFS format often goes unrecognized; music file format limitations (such as WMA or AAC) may be unsupported on certain models, with high-definition audio/video files being more prone to errors. System software bugs could also be the culprit, like failing to reconfigure multimedia settings after firmware updates. Recommended solutions: test the USB drive's status on a computer and repair errors if necessary; back up data before formatting; choose high-quality USB drives to avoid the high failure rate of cheap products. Avoid using oversized files regularly and keep capacity below 16GB to reduce system load.

As an experienced driver, I've figured out ways to deal with USB drives that won't play. Step 1: Unplug and replug the USB drive to ensure secure contact, and clean the USB port of dust. Step 2: Try another USB port or a different USB drive to test if it's a system issue. Step 3: Connect to a computer to check if the USB drive is damaged; if readable, delete unnecessary files to free up space or reload music in MP3 format. Step 4: Format the USB drive to FAT32 and try again. If it still doesn't work, restart the vehicle by turning it off for a few minutes before turning it back on; if the issue persists, consider updating the car's system or checking the port hardware. These routine operations are usually sufficient without spending much money, and choosing a smaller capacity USB drive tends to be more stable.
