What causes severe jerking when starting the Roewe RX5?

[LeBrynlee]

The reasons for car jerking are as follows: 1. RPM mismatch: The jerking occurs because the engine speed is not synchronized with the clutch plate speed. 2. Sudden acceleration or acceleration after braking: These two situations are most likely to cause jerking. The computer's shifting logic analyzes the driver's throttle input. Normally, when the driver gradually presses the accelerator, the computer's default logic only requires upshifting to complete the acceleration. However, due to excessive force, the clutch realizes during upshifting that a downshift is needed to fulfill the intention of sudden acceleration, and immediately initiates a downshift. During this back-and-forth process, power cannot be transmitted smoothly, leading to jerking.

I've repaired quite a few Roewe RX5 vehicles, and jerky starts are quite common. This is mostly an automatic transmission issue, where worn clutch plates or improperly adjusted torque converters cause clunking noises during gear shifts. It could also be due to unstable engine idling, with carbon buildup on spark plugs or fuel injectors leading to sluggish throttle response. Software faults can also contribute, as incorrect ECU control over shift timing results in jerking. I recommend first checking the transmission fluid—dirty fluid can exacerbate the problem—and cleaning the spark plugs. If there's no improvement, don’t wait for it to worsen; take it to a professional shop to diagnose the ECU and clutch system. I’ve seen cases where delaying repairs led to costs multiplying and compromised driving safety. Regular maintenance of transmission fluid and engine systems can prevent most issues, ensuring smooth starts.

My family's Roewe RX5 also experienced jerking during startup, where the car would lurch forward and then stop abruptly when stepping on the accelerator, making the ride very uncomfortable. There could be several possible reasons: the most direct one is that the transmission clutch hasn't been properly broken in, or a clogged fuel line affecting gear shifts; engine carbon buildup can make low-speed driving less smooth; incorrect computer system settings might also cause this stuttering sensation. After having it checked, I found the air filter was dirty, and cleaning it improved the situation when lightly pressing the accelerator. However, I still recommend regularly changing the transmission fluid and checking the spark plugs to prevent minor issues from escalating. This kind of jerking not only affects comfort but could also lead to accidents if the car suddenly stalls in traffic, so addressing it early provides peace of mind.

This crappy car always jerks when starting. I've done my research. The automatic transmission of the Roewe RX5 is prone to issues - clutch slipping or torque converter failure causes shaking. Worn spark plugs or ECU software bugs could also be the culprits. It improved slightly after I updated the software, but a proper inspection and maintenance is needed for a real fix. Don't delay, as the jerking damages the car and wastes fuel.

The Roewe RX5's jerky start is quite dangerous. I once experienced sudden stalling while driving, which nearly caused a rear-end collision. The issue is likely related to the transmission or engine system, possibly caused by significant clutch wear or unstable idle speed leading to jerks. It's recommended to first check the transmission fluid and spark plugs. If that doesn't help, seek professional assistance to adjust the ECU settings. Ignoring this poses high risks; early repair ensures safety.

As a long-term maintainer, I recommend addressing the jerky start of the Roewe RX5 through maintenance. Old transmission fluid or clutch wear are the main culprits, and checking and replacing the fluid can alleviate the issue. Engine carbon buildup or ECU errors can also contribute to the problem; regular cleaning of spark plugs and software upgrades can help reduce jerking. Cultivate the habit of smooth starts and avoid sudden acceleration to protect the vehicle. Ignoring it will accelerate component wear and increase repair costs.
