What is the reason for the popping sound in the exhaust of the tenth-generation Accord?
2 Answers
The popping sound in the exhaust of the tenth-generation Accord is caused by exhaust valve erosion or poor sealing, which prevents the cylinder from functioning properly. Occasionally, the engine may experience carburetor backfire during operation, requiring timely repairs. Taking the 2018 Accord as an example, its body dimensions are: length 4893 mm, width 1862 mm, height 1449 mm, with a wheelbase of 2830 mm. The 2018 Accord is equipped with a 1.5T turbocharged engine, delivering a maximum power of 143 kW and a maximum torque of 260 Nm. It adopts a MacPherson independent front suspension and a multi-link independent rear suspension.
I've been repairing Honda Accords for over a decade, and the chugging sound from the exhaust is mostly caused by leaks in the exhaust system, such as aging gaskets or rusted perforations at pipe connections, allowing gas to escape and create that chugging noise. Engine misfires are another common culprit—when one or more cylinders aren't functioning properly, possibly due to dirty spark plugs, faulty ignition coils, or clogged fuel injectors, leading to incomplete combustion. Internal damage to the muffler or a blocked catalytic converter can also produce this noise. Ignoring it while driving may lead to increased fuel consumption, reduced performance, or even failure to meet emissions standards. During routine maintenance, check for black smoke from the exhaust and pinpoint which section of the pipe the sound comes from—it helps diagnose the issue quickly. Don’t delay if you notice this; visit a reliable repair shop ASAP to prevent minor issues from escalating.
