Something I have started to notice a little more recently is that if I accelerate really hard in first, I get quite a shudder from the rear end?back area? Can't be more specific sorry. Yesterday it actually stopped as I was attempting to make a left turn, I have also noticed that my rpm doesn't go past 1. It's likely a classic case of warped rotors. It is probably a simple fault that is doing this as it only shudders when I accelerate or put the engine under slight "load" when going up a slight hill. 6litr automatic transmission model 2006, my car start normally, accelerate normally , gear shifting is normal, even Rpm is normal at all stages, but when I reach at speed of 40km or above the car start lossing power while I start pressing pedal more it become normal, am facing this issue since a week please reply me. Since two days i've each time the shudders: - only on 3 / 4 / 5th gear. Looking back, the condition first started as a rattle when depressing the accelerator pedal off of idle. Low speed shudder problem. When I accelerate and am between 1500-2000 rpm, I feel a shudder / slow vibration from the center of the car, I think. Hi everyone, I'm buying my first car soon and I have narrowed it down to an Accord 06/07 or 2008-2010 model year.
