 We bought the truck new. The check engine light has come on 7 times. Now the engine needs to be replaced. We have put close to a $500 in repairs into this truck every year for the last 7 years. We had to replace tires after the Firestone recall, the truck has had a shake in it ever since. When we go over a bump in the road or our driveway, the truck rocks so bad I feel like I have whiplash. I will NEVER buy another Explorer again. I begged my husband not to buy this one, now look where we are!
