What parts might be causing abnormal noises during the operation of the XPeng P7?

Abnormal noises during the operation of the XPeng P7 may originate from the transmission or the engine. Transmission noise: If the car makes abnormal noises while idling, and the noise disappears when the clutch is depressed, it indicates that the noise is caused by a transmission malfunction. Transmission noise is generally caused by bearing or gear wear. When the car is accelerating sharply, noises can be heard coming from the chassis. Solution: Since the transmission has many components, the causes of noise are relatively complex. Therefore, regardless of the type of noise, timely repairs are necessary (transmission repairs are costly, so regular inspections and frequent oil changes are essential). Engine compartment noise: Some sounds from engine vibrations are normal, but there are exceptions, such as the high-pitched squeal of a belt, which is usually caused by belt slippage. Another example is the sharp sound of metal parts rubbing dryly, which is often due to damaged bearings in the generator, water pump, or power steering pump. Solution: If the engine produces a sound like air leakage, it could be due to a blocked exhaust system, a leaking or broken vacuum tube. If there are unusual noises inside the engine, these are generally major faults, and it is advisable to send the car for inspection and repair as soon as possible.
With my twenty years of experience driving all kinds of cars, I can tell you that the noises in the XPeng P7 while driving could come from several places. The most common is the chassis components, like loose shock absorbers or suspension arms in the suspension system, which can creak when the car bumps—this tends to happen more with frequent driving on rough roads. Then there's the braking system; if there's debris or sticking in the brake pads or calipers, it can produce a sharp grinding noise, especially noticeable during low-speed turns or braking. Tire issues shouldn’t be ignored either—uneven tire wear or small stones stuck in the tread can cause a humming resonance, making the ride feel rough even on smooth roads. Sometimes, interior trim panels aren’t secured properly, and a single bump can make them rattle. Though it may seem minor, the constant noise can be distracting and annoying. My advice is to get it checked as soon as you hear any unusual sounds—don’t delay, or you might end up damaging a perfectly good car.
As an EV enthusiast, I think the abnormal noises in the XPeng P7 might differ from traditional gasoline cars, mainly due to its unique components. For example, when the motor is running, worn bearings or a dusty cooling fan can produce low-frequency humming or hissing sounds, especially noticeable during acceleration or deceleration. The battery pack could also be problematic—if the battery compartment isn't securely fixed or internal wiring is loose, it might rattle when going over bumps, which is a serious concern for longevity. Additionally, issues with the suspension's electronic control system, such as faulty sensors or damper modules, can result in unusual clicking sounds. I usually use an onboard OBD scanner to quickly read error codes for troubleshooting, saving unnecessary hassle. Regular cleaning of air ducts and the undercarriage can prevent many issues—EVs require high precision, so maintenance shouldn't be taken lightly.
