What to do if the Roewe i5 has severe low-speed jerking?
4 Answers
Most of the time, it is because the transmission's response speed is not fast enough, and the upshift speed cannot keep up with the throttle input, so there is a jerking sensation at the moment the transmission shifts gears. Most of the time, it is due to the intervention of the energy recovery system, which places some burden on the engine and affects the engine's speed, resulting in a jerking sensation. Because when driving at low speeds, the gears frequently switch between first and second gear, and the power transmission cannot be smoothly completed in a short time, this causes the common low-speed jerking.

Driving the Roewe i5 with frequent low-speed jerking is quite a common issue, mainly caused by the dual-clutch transmission. If it persists after the break-in period, it's likely due to clutch slippage or control module program lag. It's most noticeable in traffic, especially during the 1st to 2nd gear shift when the car jerks—light throttle input won't move it, while heavy input causes sudden surges. Don't ignore it: first, ask the 4S shop to upgrade the transmission software during maintenance—many owners report improvement after a TCU firmware update. If that doesn't work, inspect clutch wear and check for degraded/low transmission fluid. Ease on the throttle and avoid sudden braking/acceleration to mitigate symptoms. If unfixable, use the warranty instead of paying for a full transmission replacement.
Driving the Roewe i5 feels jerky at low speeds, which really annoys me in traffic jams. A friend suggested it might be due to aging spark plugs causing poor ignition or excessive carbon buildup in the throttle body, leading to inaccurate idle fuel injection. A while ago, I cleaned the throttle body myself and found thick sludge inside—after cleaning, it felt much smoother. As for the transmission, the dry dual-clutch design is prone to overheating and wear, and sudden acceleration can cause clutch engagement issues, resulting in jerking. It's best to develop a habit of gentle starts and shift to neutral at red lights to reduce semi-engagement. Try using 95-octane fuel or adding some fuel system cleaner to remove carbon deposits. Getting a fault code read at a repair shop is the most accurate method—once, a faulty wheel speed sensor was detected and replaced, solving the issue. For older cars, check the engine mounts, as engine vibrations transmitted to the cabin can also feel like jerking.
I understand the feeling of the Roewe i5 lurching forward at low speeds. The most likely cause is an overly aggressive gear-shifting program, where delayed downshifts result in a dragging sensation. Don't rush into major repairs—first try resetting the transmission's self-learning: after a cold start, shift to D (Drive) and hold the brake for 10 seconds, then shift to R (Reverse) and hold for another 10 seconds. Repeat this several times to let the computer relearn the clutch engagement points. Also, check if the air filter is clogged, affecting air intake, and ensure tire pressure isn't too high, as this can transmit abnormal vibrations. Reduce heavy loads in the car, as overloading can worsen jerking during acceleration. Using manual mode and driving slowly in lower gears can help alleviate the issue. If the problem persists, visit a 4S shop to request a control unit update—some batches have software defects. Remember to address this before the warranty expires; replacing the clutch assembly out of pocket costs over 2,000 yuan.
