This is a copy of a post that I put onto an Oz newsgroup, but maybe
other Hyundai owners can commet:
The Sonata is off the road until it can be towed to the service
dealership on Monday.
Appears to be the body computer has developed a mind of its own –
should I rename the car HAL? About 6/12 ago I got the "check engine"
warning light and I had absolutely zero acceleration. The workshop
said it was the throttle position sensor, and I assume a good shot of
CRC 2-26 was applied as it was quite OK after that. Then a week ago,
it reappeared (warning light and throttle prob) but along with the
"ESP Off" light. A few quick thumps on the accelerator cured the
response problem. After a while the ESP light went off. Just as I
arrived home the check engine light went off. Next day, I went to get
into the car and noticed the brake lights were on – car was empty and
locked. Huh? But only the two in the rear quarter panels, the mid-
mount one wasnt on at all.
OK, they went off by the time I got home. But apparently during the
night, Mr Ghost Driver sat there and applied the brakes all night.
Flat battery next morning. As it was 3 years and a bit old, to be on
the safe side, I got NRMA to deliver a new battery – I was hoping that
maybe a flattish or defective battery can cause strange symptoms as it
did in a friends Nissan, and that disconnecting the battery could
cause a system reboot and maybe fix the problem. No such luck. As soon
as the new battery was connected, the rear brake lights came on. But
not the mid-mount again. The NRMA person pressed the brake, still no
lights. Then went out ( or went on, can’t remember now) when he took
his foot off.
Now as I consider it too dangerous to drive with the brake lights
giving false indications, I have ordered a tow truck to pick it up Mon
morning. Reason I post this here, is there anything I might be missing
so that I dont walk into the service area with a complete "DUH" look
on my face?
