Why does the Corolla make abnormal noise when accelerating?
2 Answers
Corolla makes abnormal noise when accelerating due to cold start acceleration. Here is some knowledge about the Corolla: 1. Introduction: The Corolla, formerly known as "Huaguan," is a brand under Toyota Motor. The Corolla is equipped with Michelin 215/45-R17 tires, TRD-Sportivo high-performance shock absorbers, TRD-TF4 17-inch sport rims, reinforced clutch, and high-performance brake pads to ensure ideal sports performance. 2. Space: The Corolla has also been lengthened in terms of body size, with a wheelbase of 2700mm after lengthening. In terms of seating space, a 177cm-tall tester adjusted the front seat to the lowest position, with a headroom of one fist. When the tester moved to the rear seat, the headroom was two fingers, and the legroom was one fist and three fingers. The floor bulge in the middle of the rear seat of the Corolla is very small.
I've been into cars for many years. When a Corolla makes strange noises while accelerating, it's mostly due to engine component issues, such as aging spark plugs or uneven ignition, causing noise under heavy load during acceleration, sounding like a clattering or clicking noise. Loose or leaking exhaust pipe joints can also produce a hissing sound, especially noticeable during sudden acceleration when pressure increases. Worn clutch or loose driveshaft connections in the transmission can also cause strange noises, as if the chassis is shaking. Don't rush to push the accelerator; first, take it to a repair shop to check the chassis fasteners and engine system. Timely repairs can save more on maintenance costs and prevent long-term wear from causing more serious failures, affecting driving safety. In short, strange noises may seem minor but can hide big risks, so it's best to address them as soon as possible.
