What is the rumbling sound when the Sagitar accelerates?

[GabriellaAnn]

When the FAW-Volkswagen Sagitar makes a buzzing sound while accelerating, it indicates that the engine oil level is insufficient and needs to be replenished immediately. The abnormal noise will disappear once the oil reaches the normal level. More relevant information is as follows: 1. Acceleration Time: During the 0-100 km/h acceleration test of the Sagitar, the result was 10.18 seconds. Similar to previous dual-clutch transmissions, the protection program does not allow the engine to start at high RPMs during the initial acceleration phase, so the power is not fully released in the beginning. There is no wheel spin or lifting of the front end, ensuring a smooth start. 2. Transmission: Due to the transmission intervention program, the power output is not optimal at the start, and the RPM does not rise quickly. However, the gear shifting speed is indeed impressive, with responsive reactions and no significant time wasted. The power remains ample in the mid-to-late stages. The 1.4T low-power version is nearly 2 seconds faster, so the Sagitar does not have a significant advantage in the 0-100 km/h acceleration competition.

My Jetta has been making a humming noise during acceleration after long-term use, and it feels like it's coming from the wheels or chassis. It might be due to worn-out wheel hub bearings—those components bear weight and rotate, so when they wear out and loosen, they produce that humming sound, especially noticeable when you step on the gas. Tires could also be a factor: if they're worn unevenly or have incorrect pressure, the wheels become unstable while rotating, causing that noise. Last time I took it to the repair shop, the mechanic checked it on a lift and found the rear wheel bearing was the issue. After replacing it, the noise disappeared. I suggest you first check your tire pressure and listen to whether the noise changes significantly when turning—that’s a strong sign of a bad bearing. Don’t delay; this issue increases fuel consumption and can be dangerous—if the wheel fails, it could be disastrous. A professional shop can fix it for a reasonable cost, so the sooner you handle it, the better. Also, this is a common issue with the Jetta model—regular lubrication during maintenance can help prevent it.

A humming noise during acceleration in cars often stems from wheel hub bearing failure. This component connects the wheel to the axle, and when worn, the increased clearance produces a continuous roar. Tire issues are also significant: improper balancing or uneven wear can cause vibrations that transmit noise during high-speed rotation. Exhaust system leaks or resonance can sometimes contribute to the problem. Having handled many such cases, I advise owners to promptly inspect—first use a multimeter to check if electrical circuits are affected, then lift the car and spin the wheels to listen, which helps pinpoint the issue. If the noise appears above 40 km/h, it’s likely wheel-related. Avoid self-diagnosing complex components; rely on a technician with proper tools for safety. Ignoring it may worsen chassis damage or lead to accidents. Regular maintenance, including periodic checks of bearing seals, can extend their lifespan.

My Sagitar has been making a humming noise recently, which is especially annoying when accelerating. I don't know much about cars, but my friend said it might be a wheel issue, like worn-out tires with flattened treads causing vibrations and strange noises at high speeds, or loose wheel hub bearings making louder noises when turning. It could also be some loose fasteners in the car's chassis. Try checking if there are any stones stuck in the tires or if the tire pressure is sufficient. If the noise persists after changing to new tires, you should take it to a shop. The humming sounds like it's coming from the road surface, and prolonged driving with it can be distracting and affect safety. It's best to address it promptly before it worsens.
