    I started my LX last night, backed out of the driveway and noticed the "ESC
    Off" light was on. I noticed the "CEL" was on too. The ESC switch had no
    effect on the light. I pulled out onto the hiway and had NO acceleration. I
    noticed the engine would shift at 2000 rpm and topped out at 2000. (about 60
    mph) It took over 1/2 mile to reach 60 mph. Is there a "safe mode" on this
    car. I arrived at my destination and upon leaving the "ESC Off" light and
    switch were functioning normal. I eased the pedal to the floor and started
    to smoke the tires. The car ran great again. The CEL was still on but it
    went off after a few cycles. Engine ran good the entire time. Maybe a
    computer glitch? Any thoughts?

    Rob,

    My wife had the exact same thing happen about in our 06 LX about 3 months
    ago. She brought is back home, I got in it and the CEL came on, but no other
    symptoms exhibited. After 4-5 more start cycles, the light went off and
    nothing has happened since. We live about 90 miles from the closest
    dealership so it was a few days before I could have it checked out and by
    that time the light was off and the tech didn't find any code issues, nor
    had they heard about any similar instances with other 3.3L owners.

    YMMV

    Sounds like the computer saw a problem when you initially started it.
    Because of the electronic throttle, some issues will put you in a limited
    power mode as a limp-home. You should take it in and have it checked.

    Thanks... but I've played that game with this dealership before. (with a
    4cyl Mazda) They put the car on the computer told me it showed nothing and
    charged me $80 because they can't charge Mazda for warranty service when the
    diagnostics shows nothing. At 30,000 the car had a misfire that even the
    dealership could feel. They wanted to do a full tune up for some ungodly
    amount ($600 or so) to SEE if that fixed it. I bought plugs and wires ($12 &
    $80) and installed them. Car ran great then. I think I'll wait until CEL
    stays on.

    It'd be my advice to stop using that dealership. If they're the only
    Hyundai game in town, my condolences. That sort of treatment would stop
    me from purchasing products which I'd need to have serviced by them.
