- the contact owns a 2001 GMC Yukon. While driving he heard a loud noise that sounded like metal clashing on metal. The contact took it to the dealer, and they stated that the failure was due to a a defective flex plate. He felt that this was a huge safety problem because the failure could result in a loss of the ability to stop the vehicle. Also, this was a huge concern for anyone who was pulling a travel trailer. The contact could provide pictures if needed. The failure was 80,000 miles. The noise was noticed a idle and particularly at acceleration. It was determined that the flex plate connecting the crank torque converter was fractured. The consumer stated the probable failure mode on this part is flexural fatigue which would result misalignment of the transmission input shaft and the crankshaft, or excessive run out on the attachment surface of either the crankshaft or the converter.
