    Strangest experience happened to my wife in her '06 Sonata V6/LX.

    Caveat, mind you, she called her in-house tech support (*me*) after the fact
    and the car only duplicated 1 out of 3 symptoms with me driving.

    When she got in the car to pick up the kids this afternoon, the check engine
    light and the ESC Off light stayed lit beyond the system check. She drove to
    the bottom of the hill that leads up to our house (~1 mile) and turned onto
    the highway at which time she says that the car wouldn't go any faster than
    20MPH. (Some sort of failsafe mode perhaps?) She immediately turned around
    and brought the car home and left me a message to see if I could see a ready
    problem. I did a visual inspection inside and out, underhood, undercarriage,
    etc., tightened the gas cap several notches, checked the fluids and took her
    for a spin. I still get the check engine light, but not the ESC off or
    failsafe mode (if that is what it was).

    The reason I asking the next series of ?'s is not because I'm being stupid
    for not taking it to the dealership to get the codes read right away, it is
    simply because we live in the sticks and it is a 103 mile drive to the
    closest Hyundai dealer, the Service Manager there was not able to provide me
    with much insight or clear recommendations as to what I should do and I'm
    trying to determine my best options.

    Do you have any similar experiences with this model? Ideas?

    I called our service manager and he said that I could take it to the Kia
    dealership across the state line (80 miles closer) and have the codes read,
    but they couldn't do any repairs if necessary, and that he didn't *think* it
    would hurt to drive it to them as long as the C/E light isn't blinking (it's
    not), but he really wasn't sure, what do you think?

    Would the roadside assistance provide towing back to the dealership in such
    an instance? (SM here didn't know)

    TIA

    Your car has gone into some sort of power management mode. Whatever it
    saw
    was serious enough that the computer probably thought the electronic
    throttle control might not operate properly. Roadside should tow it to
    the dealer. In fact, that's what I'd recommend considering it was in
    power management. Even so, you'll still need to trek to the dealer to
    pick it up.

    Thanks for the reply HT. This morning, everything was back to normal, but
    based on your comments, I'll get it to the shop for a look-see anyhow as
    soon as possible.

    I don't know if this will help, but yesterday I was at a Hyundai dealership
    and out of the blue the salesperson started telling me that if the check
    engine light comes on, be sure to check that the gas cap is closed all the
    way until you hear it click. He said people see the check engine light and
    bring it someplace to be fixed and sometimes end up with the wrong work
    being done on the vehicle when it was just the check engine light sensing
    the gas cap not being tightened correctly. He said something about the
    vacuum which didn't sound logical to me, but I guess they have seen this
    come up and he wanted to let me know about it. Maybe it was BS, but that's
    what he said to check if the light comes on and you don't know why.

    It's not BS - it happens on all cars today. It does not result in the OP's
    symptoms though. It causes nothing more than the CEL to come on.

  9. No, it is accurate. I did not know it a few years back.

    On my '97 LeSabre it came on shortly after getting gas at a full serive
    station. Great feeling when you still have 250 miles to travel to get to
    your vacation destination. I had, at the time, no idea why it went on but
    after a couple of days, it stopped. Meantime, the car seemed OK, but I was
    concerned. I was tepmted to stop at a dealer to have them read the code but
    since the car was running OK, I did not.

    On my '01 LeSabre, the DIC reads ot "Gas Cap Loose" so you know. They after
    you tightent he cap, it takes about 10 cycles of starting to have it go out
    again (after you tighten the cap) At least I knew what the deal was when
    that happened.

    I can see an unscrupulous shop making a quick $500 to tighten the cap for
    the unsuspecting.

    Interesting. I am curious what the issue is that makes them want to monitor
    the gas cap. The salesperson said it needs to make a seal so it can create
    a vacuum in the gas tank. If that's true, I'm sure there's a good reason.
    But I would think that a vacuum would be something that would not be good to
    have.

    I thought maybe it's a safety feature designed to keep gas from leaking out
    if the vehicle is overturned in an MVA.

    It's about pressure, not vacuum. DAGS and you will find quite a bit about
    this. It's a factor on all of today's cars.

    The body computer tests the emission system on a regular bases IF it
    detects a vacuum leak The CEL light will come on. Another thing When
    filling with gas DO NOT OVER FILL THE TANK putting that extra $1 worth of
    gas into the tank can get very expensive if gas gets into the purge
    canister or another part of the evap emission system
