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.
WHEN PRESSING DOWN ON ACCELERATOR TO GET INTO TRAFFIC FLOW SOMETHING STICKS SO THAT THE ENGINE RUNS AT HIGH SPEED UNTIL YOU KICK THE PEDAL TWO OR THREE TIMES TO RELEASE WHAT EVER IS STICKING. HAS HAPPENED MULTIPLE TIMES.
