The front passenger seat on my 2.0 sri seems to be angling towards the window when some of my slighty weighter passengers are sat in it. When i pop the catch to push it forward for entry to the rear, it seems to right itself. When it does this though it is almost like something is being released. Could it be something simple and repairable in the seat tilt control (which is also incredibly tight to move) or am i basically in the market for a new seat?
