Engine & cooling

The second problem is the oil pump. I heard a noise coming from the engine, and asked our mechanic what might have been the cause of the noise. He said the the oil pump was bad and we will have to replace the oil pump and if there was damage to the engine would have to replace that too. I understand that there was a technical alert dated March 14, 2003, just three months after I purchased my car. A class action suit was started in May 2003 but I was not informed of the suit. …

I parked my landrover Discovery in the grocery store parking lot, pulled the key out and walked toward the store. After a crashing noise I turned around to see my car had rolled back into a van. My transmission was still in "drive" and I had been able to remove the key from the ignigtion. I called my landrover dealer. After explaining what happened I asked why the key could be removed in the "drive" position, he said he didn't know and would have to look into it. He then directed me to the collision center for repairs. The next day I found out from a friend with a Discovery that his key can not be removed in "drive". When I called the dealer again he told me the key shouldn't have come out. When I questioned him as to why he didn't explain that to me the day before, he told me I had misunderstood. …
