2012 GMC YUKON Engine Problems

The contact owns a 2012 GMC Yukon. The contact stated that years ago, the engine was replaced with a rebuilt engine. Recently, after starting the vehicle, there was an abnormal banging sound coming from the engine. The banging sound continued, and the vehicle shut off without warning. Due to the failure, the vehicle was towed to an independent mechanic, and it was discovered that an engine bearing had failed, and the vehicle was diagnosed with engine failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 47,000.

Driving on loop 20 overpass on Hwy 59 in Laredo Texas suddenly the engine lost power and started to skip and miss fire while a loud tapping noise was generated, due to the loss of power and skipping, alarms showed in the main console requiring immediate service to the engine, traction and braking sys, the lack of engine power place me in a very critical and unsafe situation wherein I was about to be rear collision by the vehicle behind me. This event happened on October 17th, 2025 . I brought the vehicle to Powell Watson Motors who is the GMC dealership in Laredo Texas for inspection but they refused to accept the vehicle due to the age of the vehicle. I feel this safety issue must me corrected and resolved in order to avoid accidents and deaths.
