What Causes the Noise When Engaging Reverse Gear in the New Sagitar?

Engine Noise: Symptom Description: There are various potential causes for abnormal noises in the engine compartment. Most people identify the noise as originating from the engine compartment based on the sound, which is typically a high-pitched metallic screech or a whistling noise. Solution: Engine noise indicates a change in the technical condition of a certain engine component, often due to excessive wear or improper assembly and adjustment. Some noises may even signal potential catastrophic engine damage. Therefore, when abnormal engine noises occur, immediate repair is necessary to prevent further damage. It's important to note that most engine-related noises cannot be resolved by the vehicle owner alone, and professional inspection and repair at a service center are recommended. Transmission Noise: Symptom Description: If there is a "rustling" sound from the transmission while driving, which disappears when the clutch or accelerator is pressed, or if there is a whistling-like sound during gear shifts. Solution: The transmission consists of numerous components, making the causes of noise complex. When analyzing, pay attention to whether the noise is speed-specific (e.g., some planetary gears produce noticeable noise around 50 km/h) or gear-specific, which is crucial for diagnosing transmission issues. If noise occurs in a specific gear, it is likely related to components affecting that gear's power transmission. If noise is present in all gears, it may indicate a fault in the constant-mesh gear shaft or insufficient transmission oil. Additionally, observe whether the noise is linked to specific actions like gear shifting, starting, rapid acceleration, deceleration, or turning, as these are effective indicators for diagnosing abnormal noises. Speed and direction changes are particularly important for identifying rear axle issues. If transmission noise is prominent, it is advisable to have a professional workshop inspect and replace the faulty components. Wear-Related Noise: Symptom Description: While driving, pressing the accelerator or brake may produce minor noises from certain parts of the vehicle. Though the noise is not loud and does not affect normal driving, it can cause concern about potential faults.
I often hear a clicking sound when reversing my new Sagitar, which is quite annoying. Most of the time, it's a minor issue with the transmission, where the gears don't engage smoothly in reverse, possibly due to aggressive shifting or frequent sharp turns in daily driving causing extra wear. Insufficient oil pressure after prolonged use of a new car can also trigger the noise, as aging transmission fluid loses its lubricating protection. I check the oil level every six months to prevent the problem from worsening. Additionally, loose clutch plates or incomplete break-in are common issues, especially noticeable in the first few months of a new car. If ignored, gear damage will worsen, and replacement costs can run into several thousand. It's advisable to visit a professional shop for an in-depth diagnosis early on, rather than risking a breakdown on the road.
My new Sagitar makes a metallic grinding noise when reversing, which I think might be related to my driving habits. For example, quickly shifting into reverse while parking may cause excessive impact on the gears; or uneven force distribution during uphill reversing could accelerate component wear. Many owners on forums share similar issues, especially with automatic transmission models, where abnormal transmission sensors often trigger false alarms and strange noises. Check if there's any looseness in the brake system or linkage rods, and reversing more slowly in daily use can reduce stress. If the noise worsens, it might indicate a damaged bearing or lack of lubrication. Try adding transmission fluid promptly to see if it helps. If not, visit an authorized dealer for software updates or warranty service.
The noise when shifting into reverse gear is indeed a cause for concern. I believe the reasons are mostly mechanical, such as poor gear engagement or worn drive shafts. It's common in new cars, especially in wet and cold weather when oil pressure fluctuations can cause issues. It's recommended to immediately visit a 4S shop for inspection—don't skimp on repair costs at the expense of safety. A simple method is to use an OBD tool to self-check for error codes, but professional mechanics should be the first choice. Maintaining monthly fluid checks and reducing prolonged reverse driving can help prevent this.
