Hyundai Elantra 2003 ?

Question

I was driving across 800 miles.  In the car for 8 hours already, then we hit construction (stop and go).  It was terrible.  The temp guage didn't show hot and no lights came on but all of a sudden when I hit the gas pedal nothing happened.  The care never did die, it kept running it just wouldn't go anywhere.  I had a half a tank of gas so that wasn't the problem.  I managed to get off the highway and onto a side road.  I set there for an hour and a half for help.  When help arrived I started the car for him to show him what it was doing and it ran perfect.  We got back on the road and completed our trip (another 4 hours).  What do you think was wrong with the car as I am headed out again for another road trip and I don't want it to happen again.  It hasn't done that again for since and that was 2 months ago.

I believe, but you need to confirm, your car has a "throttle position sensor" .  I know the later models do. It is part of the electronic and computer controls that make modern engines efficient. If the sensor goes bad or has an intermittent problem it won't "sense" input from the throttle/gas pedal. This sensor is independent from the component that controls the idle which is why the engine could idle but no input from the gas pedal was registered.

I have limited experience with Hyundai dealers but the one I had w/my son's 05 Tucson was very good. I recommend that before your next long trip you have them run a diagnostic test as well as catch up on preventive maintenance items like oil/filter, check timing belt, new air filter [actually easy to do yourself] correct tire pressure. Drain and refill coolant - a flush isn't necessary. New brake fluid every 24 months keeps corrosion from fouling your ABS system. If you haven't done a tune [plugs and new ignition wires] in the past 50-60k miles do that.  If it is an automatic have the fluid drained and refreshed with new fluid. A trans flush is unnecessary. Hyundai specs a certain fluid type so don't do it with the wrong stuff at a quickie lube and donut shop.

Sometimes as the summer driving season approaches the dealer will be advertising specials online at their website under "service" so check that before you go. Also use Bing or Google to check the yelp ratings of the dealer before you choose one if you are in a larger metro area.

Well, if you have any doubts, consider reading about the miraculous success that Hyundai is having. They only build 7 model therefore they can not have great success if one of those models were not dependable. If that's not enough information for you, then go visit one of the Hyundai dealership's service department and see that they are strangely, and noticeably not very busy. I would assume that building reliable automobiles would be the only way that they could offer a 100,000 mile warranty. I personally drive a Mercedes-Benz however, I will tell you that I love all the new Hyundai models that have been released this year and also, how fascinating Hyundai has become so overwhelmingly successful. That is a comment you can depend on! Good Luck!
