I own a 2008 smax and two weeks ago started having the following problem. The dealer has no clue and is trying various things to no avail for 4 days already.
The issue is that about an hour after I turn off the ignition, the break lights on the right side are turning on. It can take 30 min or couple hours and sometimes it doesn't happen at all but I had situations when it turned on all night.
I noticed that when it happens and I tuern the ignition on, the right signal is blinking. The way to turn it off it to turn the lights on and off while ignition is off.
Has anyone ever seen this problem?
