What is the reason for the abnormal noise when accelerating the GAC Trumpchi GS4?

[IrisAnn]

Reasons for the abnormal noise when accelerating the GAC Trumpchi GS4: Lack of power steering fluid. Power steering fluid is a medium oil added to the power steering system, which serves to transmit steering force and provide cushioning. Power steering refers to the use of external force to enable the driver to complete steering with less effort, making driving easier and more agile, thereby improving driving safety to a certain extent. The GAC Trumpchi GS4 is a compact SUV. Taking the Trumpchi GS4 2021 270T manual comfort version as an example, its power system is equipped with a 1.5L inline four-cylinder turbocharged engine, with a maximum power of 124kW and a maximum torque of 265Nm, matched with a 6-speed manual transmission.

Last time my GS4 also made a hissing sound during acceleration, which was really annoying. The inspection revealed it was due to the aging alternator belt slipping, creating a sharp metal friction noise like chalk scratching a blackboard. Another common issue is loose underbody panels, which produce a clattering sound on bumpy roads. Turbo car owners should pay attention - a puffing sound during hard acceleration might indicate a boost pipe leak, similar to a deflating balloon. Worn CV joints can cause rhythmic knocking sounds, more noticeable during turning and acceleration. Actually, for such abnormal noises, it's best to have an experienced mechanic test drive the car and locate the source with a stethoscope. I remember last time at the 4S shop, they spent three hours on the lift and finally found it was the exhaust heat shield resonating - tightening two screws with a wrench fixed it. I suggest getting it checked ASAP. Last time I delayed and ended up damaging the tensioner pulley bearing.

My GS4, which has run 80,000 kilometers, made a gurgling noise during acceleration last month. The repair shop first checked three areas: a broken clip on the air filter box can cause a snapping sound, especially noticeable on rough roads; cracked engine mount bushings produce a metallic clunk during acceleration; the most easily overlooked is the carbon canister purge valve, with a ticking sound loudest at 1500 RPM. For turbo models, also check the diverter valve diaphragm—a hissing leak sounds like a slow tire puncture. Some owners have experienced tensioner failure, causing the belt to squeal rhythmically. It's recommended to focus on these wear-prone components. Remember to record the abnormal noise with your phone; letting the mechanic hear the sound directly is more effective than a verbal description.

Previously dealt with the GS4's acceleration noise issue, where a whistle-like sound mostly comes from a leaking turbocharger return pipe. If it's a metal grinding noise, check if the brake pad shield is deformed. For clutch models, be wary of release bearing noise, with a buzzing sound that increases with RPM when stepping on the gas. Bearing issues produce a continuous hum, like an airplane taking off. Insufficient transmission fluid can cause a clicking sound during gear shifts. Recommended steps: First, empty the trunk and test drive to rule out noise from loose items; reduce tire pressure to 2.3 to test, as excessive tire noise can be mistaken for other sounds; listen with windows open to identify if the noise is from the chassis, and with windows closed to check if it's from the engine bay.

Just helped my neighbor deal with the buzzing noise when accelerating the GS4. Here's the recommended inspection sequence: First, check the oil dipstick level - insufficient oil can cause a tapping sound from the valves. Then inspect the coolant - a faulty water pump bearing makes a noise like a washing machine spinning. Aging turbocharger pipe seals may produce a whistling sound. For manual transmission models, pay attention to clutch fork shaft noise which feels like metal friction during gear shifts. Also check if there's buzzing vibration from the electronic steering column. Don't overlook engine mount deterioration, which can cause resonant roaring throughout the engine compartment. These checks don't require engine disassembly and can be done with simple tools.

A colleague's GS4 once made a clicking noise when the throttle was pressed deeply, which was later found to be caused by a faulty knock sensor leading to incorrect ignition timing. Spark plug electrode erosion can also trigger a metallic knocking sound, like hitting tiles with an iron spoon. When the fuel pump filter in the gas tank is clogged, it produces a hoarse electric noise. Transmission valve body pressure leaks can cause acceleration stuttering accompanied by a clanging sound. Key areas to check: Fill the tank to see if the noise reduces; use 95-octane fuel for two tankfuls to test for knocking; turn off the AC during rapid acceleration to listen for compressor noise. It's recommended to visit a shop to connect a diagnostic tool and read the fault codes, with the OBD port located below the left side of the steering wheel.
