I purchased a dealer certified 2008 XC70 in Feb 2013 which had a warranty until Feb 2014. On March 7th the AWD spontaneously disabled. The car has 49K miles on it. The dealer is telling me that is a $1800 to replace the DEM. The error code they are giving me is P188914 and say that the DEM has power and ground but is not responding. I specifically asked if the temperature sensor is at fault and they said no. The roads here has been really rough because of the frost heaves. I have 4 matched ties.
Naturally I am waiting to hear if the dealership is going to do this under warranty as this happened 7 days post expiration.
But I have to ask - is this something others have experienced? A major fault just post warranty - or the AWD spontaneously going? Is there something they could do that does not cost $1800 first?
