What Causes the Zizi Sound When Driving the Envision?
2 Answers
The zizi sound when driving the Envision may be caused by vibrations from the trunk, dashboard, or doors. Below is an extended introduction about the Envision: 1. Positioning: The Buick Envision is positioned as a midsize SUV, with a relatively large body size and ample interior space. The car's exterior looks powerful yet stylish, making it an ideal choice for young drivers. 2. Exterior: In terms of appearance, the 2019 Buick Envision features a newly designed intelligent drag-reducing grille, aluminum roof rails, newly styled chrome dual exhaust pipes, 19-inch multi-spoke aluminum alloy wheels, and multi-function exterior rearview mirrors. 3. Powertrain: The 2019 Buick Envision offers two powertrain combinations: a 2.0T-SIDI direct-injection turbocharged engine paired with a 9-speed HYDRA-MATIC intelligent transmission, and a 1.5T-SIDI direct-injection turbocharged engine paired with a 7-speed DCG intelligent dual-clutch transmission.
That annoying buzzing sound while driving is really frustrating! My Envision has been making a high-pitched noise similar to an electric mosquito swatter for almost two years now, especially when turning or lightly applying the brakes. Based on my experience, the most common cause is excessively worn brake pads – when the surface becomes uneven, it creates that irritating squeal. They must be replaced promptly to avoid brake failure. Another possibility could be small stones stuck in the tire treads or worn-out tread patterns, which become more noticeable at highway speeds. During my last visit to the repair shop, the mechanic also mentioned that accumulated dust on the AC fan blades can cause noise, and cleaning them usually solves the issue. Rusty sunroof rails can produce similar sounds too, especially on windy days. My advice: don't tough it out. Schedule a comprehensive inspection at the 4S店 as soon as possible – safe driving should always come first. Getting new brake pads won't cost much but will give you peace of mind on the road. Pay attention to these details during regular maintenance – prevention is always better than cure.
