Why doesn't the 2020 H9 shift up at 4000 RPM, the speed doesn't increase, and the turbo doesn't engage? When accelerating slightly harder, it shifts to third gear but jerks.

Is it normal for my 2020 Ford F-150 XLT with 5,500 kilometers to have noticeable jerking when shifting at low speeds?

MG GS, with over 60,000 km, recently having trouble starting the car. It requires several attempts to start. Once started, five or six warning lights come on, and when pressing the accelerator, the car doesn't move, can't go over 10 km/h. It often needs to be turned off or re-shifted. Sometimes while driving, pressing the accelerator doesn't speed up the car, but the engine sounds like it's in neutral. It also jerks when moving. Local repair shops are hesitant to fix it, and the 4S shop is too far away. I'm worried the car won't accelerate on the road, which could lead to an accident. Seeking help.

Is the 2022 GA6 experiencing jerking when shifting from second to third gear and also when accelerating at low speeds in third gear a common issue for this model?

When the MINI is in D gear and you brake, if there's a prompt to shift the transmission to P gear, there might be a couple of reasons for this. It could be an issue with the gearbox or a safety feature that's activating. If the car doesn't move when you release the brake, it might be due to a malfunction or an electronic system engaging to prevent movement. It's best to consult the vehicle's manual or contact a professional mechanic to diagnose the issue accurately.

For a 2020 GS5 with over 30,000 kilometers, experiencing continuous jerking when lightly pressing the accelerator at speeds above 100 km/h, but not when pressing slightly deeper, and with no fault codes, what could be the issue?

Hi fellow car enthusiasts, I have a 1.6 CVT that's been running for ten years with over 60,000 kilometers. Last month, I just did maintenance, changed the transmission fluid and spark plugs. It was running fine for the first few days, but recently it's been jerking occasionally when I lightly press the accelerator. It's similar to a manual car when you give gas without fully releasing the clutch. The engine goes "woo-woo-woo," and the whole car shakes a bit, but the speed doesn’t increase. Then, when I press the accelerator harder, it goes back to normal. Does anyone know what might be happening?

Is it normal for the Haval Jolion Comfort edition to lurch slightly when you park on a slope, shift to P, engage the electronic handbrake, and then release the foot brake?

Today, while driving my 2020 automatic Chery Arrizo 5, I heard a squeaky noise from the accelerator pedal when I pressed it to accelerate. When I released the pedal, it didn't return to its original position and kept accelerating, which scared me, so I quickly braked and pulled over to turn off the engine. I then shifted to neutral and started the engine, which roared to over 4000 RPM. After turning it off, I manually adjusted the pedal, heard the squeak again, and then it started working normally. Occasionally, there's still a noise when pressing the accelerator, but the pedal returns to normal. Does anyone know what might be causing this issue or what might be broken?
