What Causes the Fuel Tank Noise in Chery Tiggo 8?

[MacSamantha]

Chery Tiggo 8 fuel tank noise may occur due to the following reasons: Noise due to lack of baffle plate in fuel tank: When the car is moving, the fuel inside the tank collides with each other, creating noise. It has been confirmed that the fuel tank in this case lacks a baffle plate design, which leads to noise inside the tank. Noise caused by fuel tank resonance: During driving, the car generates resonance, which is transmitted to the fuel tank, resulting in noise. Noise from loose heat shield of fuel tank: There is a heat shield near the car's exhaust pipe and fuel tank to protect the tank from heat. If the screws of the heat shield become loose or the shield is deformed due to scraping, it can also cause noise.

I've been running a repair shop for over 20 years, and the issue of abnormal noises in the Chery Tiggo 8 fuel tank is all too common. There are several main reasons for this. One is the sloshing of fuel inside the tank, especially on bumpy roads or during sharp turns, where the gurgling sound can be quite loud—this might be due to loose or damaged fuel tank baffles. Another is loose mounting screws, where the tank isn't secured tightly enough, causing clanging noises during heavy vibrations—it's essential to check the chassis connection points. There's also the issue with the fuel pump; if it's aged or improperly installed, it can produce a buzzing noise, which requires a professional technician to test with tools. Additionally, residual air bubbles after filling up can cause similar sounds, so it's important to use fuel from reputable gas stations to minimize impurity buildup. In short, don't ignore abnormal noises—get to a repair shop early to tighten screws or replace parts. Otherwise, long-term driving poses significant risks, and if the fuel pump burns out, repairs become costly and time-consuming. Safety first—always pay attention to the source of any noises before driving to prevent minor issues from escalating.

I've been using the Chery Tiggo 8 for over a year, and a few days ago, the fuel tank suddenly started making a strange buzzing noise, which really worried me. After searching online, I found that it might be caused by air entering due to low fuel levels or noise from the fuel pump struggling to draw fuel. Later, at the 4S shop, they diagnosed it as a clogged fuel tank vent pipe, and after cleaning it, the noise stopped. Some also suggested checking the fuel line's sealing, such as loose or cracked fuel pipe connections, which could cause unusual noises. Now, I've developed a habit of checking the fuel gauge before refueling and keeping the tank at least half full to avoid excessive sloshing in a large empty space. If the noise persists or worsens, don't push it—stop and inspect immediately to avoid compromising driving safety or damaging parts. Remember, if it's a new car still under warranty, get it fixed promptly—it's free and hassle-free.

From a technical perspective, there are three common causes for fuel tank noise in the Chery Tiggo 8. First is fuel flow issues, where air mixing with low fuel levels causes sloshing sounds. Second is mechanical faults, such as abnormal fuel pump motor operation or loose mounting brackets creating resonance. Third is structural defects, like broken internal baffles or improper tank mounting design. During diagnosis, prioritize identifying sound location and driving conditions - noise on flat/slight slopes often indicates pump issues, while rough road noise suggests structural problems. Recommended to use simple tools like hand-checking vibration points for localization, with prompt part repair/replacement to prevent worsening.
