Esc off light coming on. The light comes on If I push the brake pedal all the way down and as soon as I start to release brake the light comes on.I mean I just start to release pressure & it comes on
The brake pedal doesn't even move an 1\8" & the light comes on. The car is in
park when it comes on.
I had a similar issue with 2012 Sonata. Also had acceleration issues, or lack there of. Took it to the dealer who told me bad battery and brake light switch. Changed both as recommended. Problem persisted. I took it back and they found I was having issues while headlights were on. They mentioned unusual wiring under steering column and offered new wiring harness for $3500 plus labor with no indication it would solve the issue. I said no thanks. Got a Carfax and found the car used to be rental fleet. Realizing it was likely an aftermarket kill switch or GPS tracker, I took it to a stereo shop. They removed the aftermarket wiring for $75. Car now runs perfectly whether lights are on or not. Problem solved!
