2010 Chevrolet Silverado Engine Problems

MY OIL PRESSURE SENDING UNIT HAS BEEN REPLACED TWICE IN TWO MONTHS. THE OIL PRESSURE WILL BE FINE WHEN STARTING THE ENGINE COLD THEN GRADUALLY AS THE ENGINE WARMS UP IT DROPS AND DROPS UNTIL THE "LOW OIL PRESSURE" LIGHT COMES ON AND THE DISPLAY SAYS TO STOP ENGINE. AFTER SHUTTING OFF THE ENGINE FOR ONLY A FEW SECONDS AND THEN RESTARTING THE OIL PRESSURE IS BACK AROUND 30 THEN WILL DROP AND DROP AND WILL HAVE TO REPEAT. THIS LAST TIME I WAS DRIVING 80MPH AND THE OIL PRESSURE GAUGE WENT DOWN TO AROUND 5. AS SOON AS IT WAS RESTARTED IT WAS AROUND 30. THE FIRST REPLACEMENT WAS ON 1/19/2016. THIS LAST WAS REPLACED 03/07/2016.

I WAS DRIVING MY 2010 CHEVY SILVERADO ON I-675 AND TRUCK EXPERIENCED IMMEDIATE ENGINE POWER LOSS, SPEED AUTOMATICALLY REDUCED TO 20 MILES PER HOUR AND ENGINE LIGHT W/ ENGINE REDUCED POWER VERBIAGE ALERTED ON DISPLAY. TRUCK ENGINE INSTANTLY STARTED RUNNING / SOUNDING ROUGH AND WOULDN'T ACCELERATE BEYOND 20 MPH. THIS CAUSED IMMEDIATE UNSAFE SITUATION FOR MYSELF AND TRAVELERS ON INTERSTATE. I WAS TRAVELING IN LEFT LANE AND SEVERAL VEHICLES SWERVED AROUND ME AS I MOVED TO RIGHT OFF ROAD, BEYOND WHITE LINE TO STOP MY TRUCK. I QUICKLY LEARNED, BY INTERNET SEARCH, THAT A TECHNICAL SERVICE BULLETIN HAD BEEN GENERATED FOR THIS ENGINE FAULT, HOWEVER I HAVE NOT RECEIVED ANY NOTICE FROM THE CHEVY OR GM CORPORATION TO DATE. PLEASE HELP ALERT THE GENERAL PUBLIC ABOUT THIS SITUATION. *TR

VEHICLE LOST POWER, ALL WARNING LIGHTS ON DASH LITE UP. MESSAGE ON DASH READ "REDUCED ENGINE POWER" SPEED REDUCED TO APPROXIMATELY 15 MPH WITH NO ACCELERATION. AFTER STOPPING AT A REPAIR FACILITY NO OBD CODES APPEARED AND ON RESTART VEHICLE OPERATED NORMALLY. A SECOND INCIDENT OCCURRED IN LATE FEBRUARY WHILE TURNING A CORNER. SAME SYMTOMS BUT AT MUCH MORE DANGEROUS LOCATION. *TR

WHILE DRIVING TO WORK IN HEAVY TRAFFIC, MY 2010 CHEVROLET SILVERADO WITH 27,000 MILE SUDDENLY LOST POWER AND SLOWED FROM 50MPH TO 25MPH IN A MATTER OF SECONDS. DUE TO THE EXTREME REDUCTION IN SPEED WITH OUT MY BRAKE LIGHTS BEING ENGAGED, A VEHICLE FOLLOWING ME HAD TO MAKE AN EMERGENCY MANEUVER, TURN IN THE RIGHT LANE, AND ALMOST STRUCK A THIRD VEHICLE. THREE WARNING MESSAGES WERE GIVEN THAT INCLUDED, ENGINE POWER REDUCED, TRACTION CONTROL OFF AND SERVICE STABILITRACK. THE VEHICLE STARTED TO RUN EXTREMELY ROUGH AND I PULLED INTO A PARKING LOT. WHILE IN THE PARKING, LOT I RESEARCHED THE ABOVE LISTED MESSAGES AND FOUND THAT SEVERAL OTHER OWNERS HAVE EXPERIENCED THE SAME PROBLEM THAT HAS BEEN LINKED TO THE THROTTLE BODY SYSTEM AND THE INTAKE. I THEN RESEARCHED IF ANY RECALLS HAVE BEEN ISSUED FOR THIS VEHICLE. I FOUND THAT A SERVICE BULLETIN WAS ISSUED BUT NOT A RECALL. I WAS ALSO SURPRISED THAT THIS ISSUE APPEARS TO HAVE NOTHING TO DUE WITH STABILITRACK. I THEN LIMPED THE VEHICLE HOME AT 20 MPH. WHEN THE VEHICLE WOULD SHIFT FROM FIRST TO SECOND GEAR IT WOULD LUNG FORWARD VIOLENTLY. I LATER CALLED THE PITRE GMC, IN ALBUQUERQUE NM, AND SPOKE WITH A SERVICE REPRESENTATIVE. I ASKED HIM IF A RECALLED HAD BEEN ISSUED FOR THESE VEHICLES IN REFERENCE TO THIS TYPE OF INCIDENT. HE STATED THAT HE DID NOT KNOW OF A RECALL BUT I COULD DRIVE IT DOWN TO THEIR SERVICE DEPARTMENT AND THEY COULD CHECK THE CODES ON IT. I WAS SURPRISED BY HIS RESPONSE INSTRUCTING ME TO DRIVE AN UNSAFE VEHICLE. I BELIEVE THIS ISSUE NEEDS TO BE ADDRESSED DUE TO THE LIKELIHOOD OF A MOTOR VEHICLE CRASH THAT COULD RESULT IN SEVER INJURY OR DEATH. HOPEFULLY GM AND NHTSA WILL NOT WAIT UNTIL THERE ARE NUMEROUS DEATHS TO ADDRESS THIS PROBLEM. THIS IS POTENTIALLY AS DANGEROUS AS THE IGNITION SWITCH ISSUE THAT KILLED SEVERAL PEOPLE. I AM A GENERATIONAL CHEVROLET CONSUMER, BUT THAT WILL PROBABLY CHANGE.

WE WERE DRIVING OUR 2010 CHEVY SILVERADO (WITH 11,951 MILES ON IT) ON THE FREEWAY IN THE HOV LANE AT APPROXIMATELY 70 MPH. THE CRUISE CONTROL WAS ON. WITHOUT WARNING, THE TRUCK JUMPED 3 TIMES AND THEN APPARENTLY THE ENGINE JUST SHUT OFF. THERE WAS NO ACCELERATION, NO POWER STEERING OR POWER BRAKES. ONCE THE TRUCK CAME TO A STOP, WE TRIED TO START IT AGAIN. THE STARTER TURNED BUT THE TRUCK WOULD NOT START. AFTER APPROXIMATELY 10 MINUTES, WE WERE ABLE TO GET THE TRUCK STARTED AND MOVED TO A SAFE LOCATION. THEN WE CALLED AND HAD IT TOWED TO A LOCAL CHEVY DEALER. THE REPORT WE GOT BACK IS AS FOLLOWS: " PERFORM SYSTEM CHECKS, SCAN CHECK SHOWS NO CODES STORED IN ANY MODULES. ROAD TEST MULTIPLE TIMES WITHOUT FAILURE, LET RUN IN STALL FOR 3 HOURS. NO STALL EVER OCCURRED. NO REPAIR REQUIRED AT THIS TIME." I QUESTIONED THE MECHANIC ABOUT CHECKING FUEL SYSTEM AND HE SAID SINCE IT WAS WORKING THERE WAS NOTHING TO CHECK. SO WE HAVE NO IDEA WHAT HAPPENED TO THE TRUCK, BUT WE ARE AFRAID TO DRIVE IT. THE INCIDENT WAS A MAJOR INCONVENIENCE TO US, BUT MORE IMPORTANT, IT WAS AN EXTREMELY DANGEROUS SITUATION. WE ARE FORTUNATE THAT NO ACCIDENT OCCURRED AND THAT NO ONE WAS INJURED. *TR

SOMETIMES ENGINE WILL NOT TURN OVER AT ALL, OTHER TIMES THE ENGINE ENGAGES, BUT DOES SO VERY ROUGH AND CONTINUES WITH A ROUGH IDLE FOR ABOUT 1 MINUTE. ONCE RUNNING, THE ENGINE PERFORMS AS NORMAL AND SUBSEQUENT STARTS ARE GENERALLY SMOOTH AND TROUBLE-FREE. *TR

TRUCK WOULDN'T RESTART WHEN BACKING OUT OF A DRIVEWAY ON THE HIGHWAY AND SHIFTING INTO DRIVE. ALSO THERE IS A VIBRATION HEARD WHEN DRIVING ABOUT 30 OR 40 MILES PER HOUR. TOOK IT TO THE CHEVY DEALER WHERE IT WAS BOUGHT AND THEY SAID NOTHING WAS WRONG WITH IT AND THAT THEY TESTED IT OUT. *TR
