As I go up a hill or rapidly accelerate on an incline the check engine light will come on. The problem points to the knock sensor (code p0326) being at fault. This does not happen often but when it does it is disconcerting. I replaced the knock sensor with a new oem part, but it too acts the same as the old one. I called the dealer and they want to charge me $90 to diagnose the problem and then any labor/parts needed to repair it. However, I have read several reports online about a software update, flashing the ecu has fixed the problem. If this is so, shouldn't this be a reason for a recall?.
