NEAR 69,150 MILES THE OIL PRESSURE GAUGE FOR MY GMC SIERRA 1500 2011, ALL AT ONCE, WENT TO ZERO GIVING ME A WARNING MESSAGE TO IMMEDIATELY STOP THE ENGINE. IT TURNED OUT TO BE A FAULTY OIL PRESSURE SENSOR. IN ADDITION OIL WAS LEAKING BADLY OUT AROUND THE SENSOR AND COMPLETELY COATED EVERYTHING IN THE ENGINE COMPARTMENT AND UNDERNEATH. A YEAR LATER THE SENSOR WENT BAD AGAIN. GMC SAYS ITS NOT COVERED UNDER THE POWER TRAIN WARRANTY AND ITS COSTING ME $400 EACH TIME IT GOES BAD. *TR
