Young Chevrolet Cadillac Inc

I have never written a bad review, but feel I must for other's protection from Young's in Owosso, MI. This is regarding a serious recall on my 2009 Buick LaCrosse. There were actually 2 recalls, but I was not aware of one on the headlights that required Young's employees to unhook the battery for the repair. They did this along with the dangerous ignition recall. After I left, a little over an hour later I was almost stranded when the ignition would first not turn-over the engine, and then afterwards OVER-throttled. Upon my immediate return to Young’s, I also explained that the clock was an hour off from the actual time, which they acknowledged. They tested the battery which registered 580 (normal) and explained they unhooked the battery to do the head light recall. I asked them to check what is NOW wrong with the car since it never had this problem. They also agreed with me that it didn't happen to them when THEY started the engine BEFORE repair. HERE IT COMES...They said they would ONLY check it for $65, which of course was unreasonable. After a lengthy back and forth it was finally stated that it could possibly be waived if they didn't cause the problem. My trust of them was to zero at this point, especially after stating to me that writing a Google review was a hostage activity by me towards them. I asked them what recourse do consumers have but to make GM & others aware of their bad business practices? I left Young's with the car over throttling, fearful of what could happen to me in the car. A professional found the problem when I took it elsewhere which is CLOSE to this online explanation "...When the battery is disconnected, some late model vehicles will lose this learned idle position, which will cause the vehicle to stall." 
This cost me over $60 to repair, also having the throttle adjusted to correct the situation, all because the battery was disconnected. There has been no acknowledgment of any wrong doing on Young's part (all the way up to management). They would not recognize it was the ACT of disconnecting the battery, not the part replaced for the hazardous ignition problem that caused the situation.
BOTTOM LINE – Young’s in Owosso has zero capability to treat their customers fairly and resolve a problem that is highly probable (and later confirmed) THEY CREATED. I felt talked down to as a female, feeling UNSAFE and AT-RISK leaving their facility. One of my last statements was I only wanted to keep my family safe by honoring the re-call. I felt their greatest concern was NOT for my safety, but to make sure I UNDERSTOOD they would get their money regardless of any and ALL circumstances. STAY AWAY FROM YOUNG’S or it WILL COST YOU!
