Cruise Control problems of the 2009 Hyundai Sonata

Basically it appears that I'm having the same brake switch issue common with many Hyundais. However, currently the '09 Sonata is not covered under any recall. The problem began at least a year ago when the esc off light would turn on at random times. It would normally clear upon turning the car off. A few days ago the esc off light would not turn off. Today I could not shift into park from drive. After searching the internet I quickly found the brake switch issue. I confirmed that my brake lights were not functional. This is something occurs with absolutely no warning which is a bit scary since I drive home on a major highway. I'm not sure how long the brake lights had been out. I also noticed that the cruise control stopped functioning when the esc off light became permanent. However, for some reason it started working again when the shift lock problem occurred. Odd. Not sure why an additional issue would make the speed control functional again.

2009 Hyundai Sonata limited 4 cyl. While cruise control was on, when resuming speed after slowing down for traffic, car continued on thru set resume speed (70) to 80+. Control reestablished by shutting off cruise control. This did not happen every times but it did happen multiple times, Mar. 12 - 14, 2010. It had not occurred before. We have not used cruise control since. Dealer could not replicate. Unresolved.

The contact owns a 2009 Hyundai Sonata. While driving 50 mph downhill with the cruise control engaged, the vehicle accelerated up to 80 mph. The dealer test drove the vehicle and confirmed the failure, but stated that nothing could be done to correct the issue. The contact called Hyundai customer support and they also could not assist. He believes that driving the vehicle would be a safety risk due to the manufacturer defect. He also believes that a recall should be issued as well as a remedy for the failure. The contact discovered other consumers that were experiencing the same issue with the same type of vehicle. The failure mileage was 16,000 and current mileage was 17,000. Updated 10/06/09.
