The OP has copy and pasted the above posts word for word on various Internet Sites. I guess getting a new motor for 50% off isn't good enough. In any mass produced product you are going to have a failure rate. This same motor is in the Silverados/Sierra which GM sells about 40,000 a month of and covers for 100K miles.

Black Bear offering their services for whatever purposes is pure speculation on your part. As is stating the vast numbers of the motors manufactured the same time as yours will ultimately fail.

Get over your frustrations and move on.
