Buick Verano's audio system produces static noise because the volume is turned up too high; try lowering the volume. The Buick Verano is a compact car under the Buick brand, with a wheelbase of 2700mm and dimensions of 4723mm in length, 1802mm in width, and 1466mm in height. In terms of comfort features, the Buick Verano comes standard with laminated front windshield glass, effectively reducing noise intrusion and providing better thermal insulation. Its multifunctional steering wheel, sunroof, USB ports, and anti-haze air filter significantly enhance practicality. The Verano adopts the new family-style design language, featuring a bold front face design and dynamic, flowing body lines.

My Verano has also had that annoying buzzing sound recently. It's most likely interference in the audio wiring – especially noticeable when phone chargers are plugged in, as electromagnetic interference travels through the power cables to the sound system. Sometimes aging door wiring harnesses or aftermarket amplifier installations can cause poor shielding. I recommend first unplugging all external devices and test driving for 30 minutes – if the noise disappears, it's charger-related. If it persists, check for oxidation at the door speaker wiring connectors, especially the driver's side door wiring. Here's a DIY trick: press different areas of the door panel while the audio is on – if the buzzing changes, there's probably a loose connection. But the safest approach is a full wiring inspection at the 4S店 to rule out control module issues.

Last time there was static noise in my car's audio system, and after a long time of troubleshooting, I figured out the pattern: every time the AC compressor started, the noise would increase, indicating interference between the generator and the audio circuit. Later at the auto repair shop, they found that the unstable current output from the generator was causing power supply pollution. They installed a filter on the power line, which solved the issue. Additionally, an aging battery can also cause this—large voltage fluctuations can lead to buzzing sounds in the audio. Now, based on my experience, static noise can be divided into low-frequency hum and high-frequency whine: a low-frequency hum might indicate an amplifier issue, while a high-frequency whine usually points to wiring faults. When upgrading the audio system, choosing shielded cables is crucial, as regular audio cables are prone to electromagnetic interference from car lights or turn signals.

Don't panic about speaker static noise—it might be simpler than you think. In my Verano, the noise was caused by a low-quality charging cable plugged into the USB port in the glove box. Switching to a metal-shielded cable immediately fixed it. Sometimes, torn sound insulation can cause resonance from speaker vibrations, and simply adding some sponge washers can solve the issue. Also, check if the noise worsens after rain, as water seeping through door seals can dampen wiring and cause short circuits. When troubleshooting, first reset the audio settings to factory defaults, or disconnect the battery's negative terminal for ten minutes to reset the system. Owners who've modified wiring should pay extra attention: incorrect audio fuse specifications can also cause noise. In fact, 90% of static noise comes from cheap aftermarket parts—factory setups rarely have this issue.
