I purchased a used 2004 Hyundai XG350L from a Honda Dealer. It had only one previous owner who only serviced the car with this dealer. I purchased the car April 2007. I've had the car for 9 months now. It ran great at first, until one day, when I started it. The engine raced so hard that I thought it was going to jump out the hood and go on its own. I had to restart it several times before it settle to normal. We have cold weather (about 20 degrees) right now and I thought it was due to this. No, it happened at 40 and even 50 degrees. One time I put it in gear and there was knocking in the engine and I had to gear it back to park. I have taken this car to the dealer, who first diagnosed it as needing a crank sensor and an accelerator sensor which also required the replacement of the belt valve. The cost for the repair was 927.00. BUT..that did not fix the problem. Two (2) days later I started the car and had the same problem. I threw it in gear and drove it to the dealer just as it was. I couldn't do more than 20 miles per hour and the it jerked, idling high and low, just crazy. The dealer diagnosed it again and stated it needed an air intake sensor and that it would cost me another $547.00. I don't think so. I told them you charged me for repairs that didn't repair it, so this cost is on them. Now, I know a little bit about the mechanics of a car, they repaired it at no cost and I picked my car up. I drove for drove for (2) day and it gave me same problems, so I drove it istraight to the dealer. They have had the car now for 3 days and still can't find the problem. They have called in the Hyundai techs to help. They h ave asked me to drive the car some computerized gadget on it for a few days and push a button if the car acts up, since it behaved itself the entire 3 days they've had it. Ok, the mechanic drove it into the bay as I left it running so that the problem was evident each time. Now, I'm no expert, but I don't the computerized gadget is going to pick on this problem, since it hasn't the three (3) they've had it. I think it's going to take some old mechanic skills and sense to come up with the solution to repair this problem. What happened that mechanics these days have to have a computer tell them what's wrong with everything,. They tell you to listen for noises and squeaks, rattles and such, but what good is it when they just hook it up to a computer to be told what to do. Well, it the gadget had ears, eyes and feelings, it probably could tell them what they need to know. You heard that medical practice it just that, practice! Well, here's a new one, practicing mechanics.
