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?
