When driving a Toyota Vellfire at speeds above 100 km/h, if you release the accelerator, the car tends to jerk repeatedly. Even after changing the engine oil and spark plugs, this issue persists.

Is the fuel consumption for the 2009 Liana 1.6 automatic reaching 10 liters per 100 kilometers because of a faulty oxygen sensor or carbon canister purge valve? I've checked the spark plugs and ignition coil, and there are no issues. Any advice from the experts?

I've got a 2012 Changhe Liana, and it's been having issues with shaking at idle, while driving, and even more when the AC is on. I've already replaced the spark plugs and ignition coils, and cleaned the fuel injectors and throttle body, but the problem persists. The check engine light comes on frequently. Does anyone know what might be causing this issue?

I have a 2017 1.4T with all-wheel drive, driven over 60,000 kilometers in 5 years. When I accelerate to 60-80 km/h, there's a severe jerking, and it's slightly noticeable around 110 km/h too. I've changed the spark plugs and transmission fluid, and checked the engine mounts, but it hasn't helped. No error codes are showing up. Anyone else experiencing this issue? It's really frustrating to drive like this. I've been to several repair shops, even the dealership, and they suggested taking apart the transmission for inspection. 😖😖

In normal mode, when coasting after releasing the throttle, the car jerks when the speed drops to 5 KM/h. Is everyone experiencing this too?

Has anyone experienced gear shift jerking after just replacing the spark plugs and cleaning the throttle? It was fine for two or three days, but then the jerking returned.

When driving above 80 km/h, there's a noticeable noise near the passenger side A-pillar. At higher speeds, like 120 km/h, the noise becomes even louder.

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?

Does anyone else feel that their Outlander feels a bit floaty at speeds above 100 km/h? It seems like the car is made lighter to improve fuel economy, which makes it feel floaty.

My 2018 automatic ZS sometimes shakes when waiting at a red light after the vehicle warms up. Between 60 to 100 km/h, the car feels like it's being pulled back, and there's a strong jerking sensation. If I press the accelerator hard to over 3000 RPM, the jerking stops. Using cruise control to accelerate also avoids the shaking. Is this a transmission issue?
