Our ESP Off light came on, on my wife's car, only when I drove it. Usually as I drove around a long sweeping left hand bend. It only happened before the brake light switch was replaced. And never after the recall fix. ( I use the brakes less around corners ). Is there a way to know if the brake light switch has been replaced in the recall?
Short answer: I would think you should be able to ring up a Hyundai Service Center, or contact iCare, and ask if the brake switch recall was done to it - I would assume it would be recorded against VIN on Hy Australia's system.
Longer answer: My smart reply (previous message mentioning TLAs) I just made not withstanding. Your subject mentions EPS (steering) which is the subject of govt. website published recall for a specific range of VINs; while your content mentions ESP Off, ESP being the stability system (which relies on steering and braking, etc. for operation), and also the brake light switch - which wasn't a govt. published recall but was a recall by Hyundai.
You say it never happened after the recall fix, then ask if there is a way to know if the brake light switch was replaced - this has me confused as to which recall is being referred to?
The brake light switch recall, per what I was told recently at the service center, was to replace the original with a modified version (no idea if P/N is the same or modified) - so if you had the brake switch recall done then it would have been replaced (unless someone really mucked up). Prior to the brake switch recall they had been replacing faulty switches, but of course the replacements had the same design issue (meaning some cars had it replaced a few times prior to recall).
The Steering (EPS) recall AFAIK is only about the steering and can/does involve a ECU update. I would think the only reason the brake switch would be replaced then would be if the vehicle was recorded as never having had the brake switch recall applied.
