One problem related to power train has been reported for the 2003 Land Rover Discovery. The most recently reported issues are listed below.
Purchased Land Rover Discovery less then a month ago, since then the dash board looks like a christmas tree with the number of warning lights that are on. Was told by the dealer that the abs modulator was out and it would $3500. 00 just for the part, even though I researched it and found a repair kit for under a $100. However, the most recent warning light is the oil light and the car over heats in a very short amount of time, and knocks and bings. After reading the several post on this web sight, I too am now part of a long list of customers that have major issues with Land Rover. What a mistake it was.
