What Causes Low-Speed Jerking in New Cars?
4 Answers
New cars experience low-speed jerking because when the upshift gearbox changes the transmission ratio, there is a significant difference between gear ratios, leading to low-speed jerking. Car Jerking: Generally, after shifting gears, the vehicle speed gradually slows down. When the accelerator is pressed, the speed and gear do not respond promptly, causing the car to move forward in a jerky manner without stalling, resulting in a noticeable jerking sensation. Low-Speed Driving Tips: When starting an automatic transmission car, avoid sudden braking. Before starting the car, shift to D gear, release the brake, slowly lift the brake pedal, and then gently press the accelerator to allow the car to start smoothly. However, avoid continuously pressing the accelerator, as this not only consumes more fuel but can also damage the vehicle.
I recently noticed some jerking sensation in my new car at low speeds, especially during traffic jams or just starting off, with uneven body vibrations. This could be an automatic transmission issue - since the car is still new, the transmission control system is still learning driving habits, and improper shift timing can easily cause jerking. Dual-clutch transmissions are more prone to this problem, as the computer may make inaccurate judgments at low RPMs, leading to unsteady power engagement. Additionally, if the engine isn't properly run-in, unstable cylinder combustion and fluctuating torque output can worsen the jerking. New cars all have an adaptation period - I recommend driving more on highways to let the system optimize itself. If the problem persists after a few hundred kilometers, go directly to the 4S dealership for a software update, which usually helps. Don't ignore minor issues as they may cause component wear over time.
Just bought a new car and it's jerking at low speeds, which makes me a bit anxious since a new car should be smooth to drive. Shaking like an old car climbing a hill at low speeds is really annoying. It might just be the automatic transmission's chronic issue, with dual-clutch or CVT often acting up during stop-and-go city driving. Fuel quality also plays a role—poor-quality fuel leads to more carbon deposits and incomplete combustion. It improved after a month of driving as the system adapted. Try switching driving modes to ease the issue or accelerate gently. No need to panic with a new car; just have the transmission checked during the first maintenance. Drive steadily, avoid stomping on the throttle, and develop good habits to prevent problems.
Low-speed jerking is common in new cars, affecting comfort but not necessarily serious. Transmission control or suboptimal engine combustion can lead to unstable power output, which may unsettle novice drivers. Prompt attention is advised to prevent accidents.
