Guys and Gals, this is real bummer
,
I think my crank bolt may have come loose Friday. When I started it up it had an abnormal clicking sound so I popped the hood and I didn’t see anything amiss, I turned on the A/C and the sound went away so I left. I drove about 50 miles with 2 stops, then the sound came back and within a mile it went from the clicking to a hard knocking. Luckily it happened right as I was getting home or I would have had to use Onstar. Upon further inspection I noticed the outer serpentine belt was coming apart at the edge. The inner serpentine belt has been chewed and about 1/3 of its normal width is gone. I have read some of the earlier posts on this problem; I didn’t have any instrument indications out of the ordinary I didn’t lose oil pressure or get any lights. I think I may have caught it before it got terminal but I am not sure. I have pictures of the belts. I only have 1028 miles on the car, it was built in November the last 3 of the VIN are 443. I cannot tell if the knock is a rod or from the front of the engine maybe an accessory pully , it is RPM sensitive. I will be on the dealers doorstep in the morning, my major concern is if the engine is shot what are my options? I don’t want a replacement engine, if it’s just a tensioner or something external no problem. My specific questions are;
1. Does anyone have the list of VIN’s affected?
2. Has anyone had GM either replace they’re car for this problem or buy it back? (Dealer input welcome)
3. is there a process to do this other than the lemon law? Do I need a lawyer?
