“I have a 2003 Land Rover that just passed 50 k and started ticking from the engine. I took it to the dealer and they told me that I had a oil pump failure and I need a new engine. That will cost 8000$. Why do we have to pay that amount of money when the manufacturer has hundreds of these failures.”
NHTSA complaint #10260217, filed 2009-02, 53,715 miles“I have experienced what appears to be the same oil pump symptoms others have complained of. Despite reading full , my truck seems to have difficulty adequately lubricating. So, some days it's sounded like a tank!!”
NHTSA complaint #10350872, filed 2010-08, 86,000 miles“Upon seeing the low oil pressure light illuminate, I researched online to see what may be the cause. I then discovered that Land Rover had issued a technical alert (ta03-1201) on march 14, 2003 stating the following issue and resolution: 2003 discovery series ii oil pump failures vehicles affected discovery series ii (lt) 3a771801 ? 3a808362 situation oil pump failures on 2003 discovery series ii vehicles may be the result of a manufacturing error. …”
NHTSA complaint #10220811, filed 2008-03, 78,000 miles“I have a 2003 Land Rover discovery. I just paid to replace the oil pump only to find out that Land Rover published a technical alert that states the only way to fix the issue is to replace the entire engine. Dowel pins on the block are misaligned due to a manufacturer error per the alert. The vehicle only has 58k miles and has been meticulously maintained. Land rover is not offering to cover any of the repair costs even though it was a manufacturer error from the start.”
NHTSA complaint #10267277, filed 2009-04, 58,000 miles“I encountered a fairly well documented problem with 2003 Land Rover discoveries. There was a manufacturers defect in the oil pump that ultimately causes the entire engine to fail. Land rover has issued a technical service bulletin acknowledging the problem yet is not standing behind their product when the discoveries breakdown. They have told me that it was a faulty part that caused the engine failure in my vehicle yet they are trying to charge me to put in the new engine.”
