Why does the Roewe 350 experience weak acceleration and abnormal noise?
3 Answers
The reasons for the Roewe 350's weak acceleration and abnormal noise include carbon deposits on the valves, idle speed motor, intake manifold, combustion chamber interior, and spark plugs, as well as poor fuel quality. Below is an introduction to the Roewe 350: 1. Positioning: The Roewe 350 is a compact sedan positioned in the A-segment market. The upgraded new Roewe offers more convenient handling, improved safety quality, and economic durability, enhancing the cost-performance ratio across the entire model range. The new Roewe features a redesigned front bumper, horizontal streamline design of the upper and lower air intake grilles, new front fog light styling, full-range aluminum alloy wheels, and a TPMS precision tire pressure monitoring system. 2. Space: In terms of space, it boasts a class-leading 2650mm ultra-long wheelbase, providing ample front and rear seating space. The versatile space configuration makes it easy to store large items. 3. Features: The new Roewe is equipped with features such as a Solig one-touch luxury sunroof, Bokuman ergonomic genuine leather seats, and a Climate-Tech fully automatic constant temperature air conditioning system.
I've encountered similar issues with this type of vehicle before. The lack of acceleration power might be due to insufficient fuel supply to the engine or ignition system failure, such as aging spark plugs causing poor ignition, making it hard to gain power when accelerating. As for the strange noises, it could be caused by loose belts or worn engine components, producing squeaking or knocking sounds during operation, which can be quite annoying. If left unrepaired, such faults can lead to increased fuel consumption, difficulty in overtaking on highways, and potential safety hazards. I recommend first checking if the air filter is clogged, as excessive dirt can affect air intake. Also, see if the fuel filter needs replacement, as a dirty one can hinder gasoline flow. If you're not comfortable handling it yourself, find a reliable repair shop as soon as possible to prevent minor issues from turning into major repairs that could compromise driving safety. With this type of vehicle, it's important to pay attention to maintenance schedules, regularly change the engine oil, and inspect the belts to avoid many potential problems.
As someone who frequently repairs cars, let me analyze the reasons: Lack of acceleration power is usually caused by issues with the ignition coil or spark plugs, where electrode erosion leads to delayed ignition. Abnormal noises mostly originate from the transmission system, such as worn clutch plates in manual transmissions or abnormal oil pumps in automatic transmissions, producing metallic friction sounds or clunking noises. The turbocharger in the Roewe 350 model sometimes malfunctions, causing insufficient boost pressure and resulting in weakened power, while the noises may also come from loose suspension ball joints or damaged bearings. Ignoring these issues could lead to engine damage or transmission seizure, making repairs more expensive. It's recommended to use a multimeter to check circuit resistance; if the resistance is abnormal, the coil is likely faulty. Additionally, listen to pinpoint the noise location—if the noise changes with speed, it might be a driveshaft issue. Get it repaired as soon as possible to avoid worsening the condition.
