weird 06 Sonata

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.
