Thanks to all the posts here and since I activated cruise today just as per below I have a new theory:Be interesting to hear if they find something in your case. Let us know.
I back out of the garage and press stick down to get it in Drive(from reverse). Probably thought it was not in drive since I always impatiently hit drive while still rolling back. Thinking I was still in reverse and witout looking, I pressed Drive shaft down for a second time..or even 3rd that day. Heres the kicker: I was in drive and by pressing down again I set cruise to 1mph or close to zero.
I then left home by modulating the accelerator and never used breaks. Took foot off accelerator at intersection and it slowed down to what seemed like a stop(the super low cruise speed set at garage). I am guessing it detected the new speed limit of the next road - 30mph (vs 25) and it went into action from the stop sign. Its why I never remember depressing the accelerator or drive stick at the stop sign.
Oh boy now I feel stupid but also learned something new Ive never had to think about before. Since I rarely use the break, cruise may be forgotten ON or set in error and cause problems.
Even before this I was not happy with car picking my cruise speed when going to a new road, now it seems could be a potential hazard.
Ill still get car checked out and report this incident perhaps something else to think about when programming features.
