Why does the Roewe 550 jerk while driving?
2 Answers
It may be caused by a damaged solenoid valve leading to jerking. Below is relevant information about the Roewe 550: 1. Exterior: The new Roewe 550 continues the highly praised styling design of the classic model, with further sharpened local lines, exuding a youthful and dynamic vibe. Meanwhile, the design of the bumper, headlights, and taillights adds much brilliance and cutting-edge appeal. 2. Interior: It employs more curves and softer treatments, making the overall feel smoother and more natural, while the matte chrome plating significantly enhances visual pleasure. The center console is slightly raised compared to the older model, bringing the operation interface closer to the driver and passengers for a more comfortable control experience.
The other day when I was driving my cousin's Roewe 550 on the highway, I clearly felt the car jerking when I pressed the accelerator. This kind of hesitation is most commonly caused by transmission issues. I checked and found that the older models of Roewe 550's automatic transmission use a DSG gearbox, which is prone to erratic shifting logic. A dirty throttle body can also cause this; if it hasn't been cleaned in over 30,000 kilometers, unstable airflow can make the car shake like it's hiccuping. Worn-out spark plugs or aging ignition coils can lead to incomplete combustion of the air-fuel mixture, resulting in intermittent power. Last time I encountered a similar situation, changing the transmission fluid immediately smoothed things out—it's best to change it every four years for this car. Don't delay if you notice hesitation; it's better to read the fault codes early to get a reliable diagnosis.
