2010 CHEVROLET EXPRESS 3500 VAN. CONSUMER WRITES IN REGARDS TO PROBLEM WITH TIRE PRESSURE MONITOR SYMBOL MALFUNCTION LIGHT AND THE DRIVER INFORMATION CENTER MESSAGE BOTH COMING ON AND STAYING ON PARTICULARLY DURING HOT WEATHER AND LONG RUNS *TGW THE DRIVER INFORMATION CENTER MESSAGE WOULD DISPLAY THE AMOUNT OF PSI FOR THE FRONT TIRES OR WOULD ONLY HAVE DASHES, AS WITH THE REAR TIRES. THE SYSTEM WAS CHECKED BY TWO DIFFERENT DEALERSHIPS AND BOTH STATED THERE WAS NO PROBLEM.

TL* THE CONTACT OWNS A 2010 CHEVROLET EXPRESS CUTAWAY G3500. THE CONTACT NOTICED THAT THE FRONT END WAS SHAKING EXCESSIVELY WHILE APPLYING PRESSURE TO THE BRAKES, CAUSING HIM TO LOSE CONTROL OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY REPLACED THE FRONT BRAKE ROTORS;HOWEVER, THE VEHICLE CONTINUED TO SHAKE EXCESSIVELY AT ANY SPEED WHEN THE BRAKE PEDAL WAS ENGAGED. THE MANUFACTURER WAS AWARE OF THE FAILURE. THE CURRENT MILEAGE WAS 53,300. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

SOMETIMES WHEN ATTEMPTING TO START THE ENGINE, IT WILL TURN OVER BUT NOT START. THE MALFUNCTION INDICATOR LIGHT COMES ON AND A ENGINE REDUCED POWER MESSAGE WILL ILLUMINATE. IF THE ENGINE STARTS, IT WILL RUN ROUGH, THE LIGHT WILL BE ON AND STAY ON, AND THE ENGINE REDUCED POWER MESSAGE WILL APPEAR. I HAD A MECHANIC CHECK FOR ANY CODES AND HE CAME UP WITH P1682, WHICH INDICATES AN IGNITION SWITCH PROBLEM. GM HAS A RECALL OUT FOR THIS CONDITION (11273), WHICH REFERS TO THE THROTTLE POSITION SENSOR CAUSING THIS PROBLEM. HOWEVER A FAULTY IGNITION SWITCH CAUSES THE SAME PROBLEM, BUT THEY WON'T FIX IT. IF THE VEHICLE IS BEING DRIVEN WHEN THIS PROBLEM OCCURS WITH THE LOSS OF ENGINE POWER AND ROUGH RUNNING, IT SEEMS THAT THE VEHICLE, IN MY CASE AN RV, WOULD LOSE SPEED AND ALMOST SLOW TO A STOP WHICH WOULD BE VERY DANGEROUS. GM RECOGNIZES THAT THIS PROBLEM CAN OCCUR, BUT ARE NOT CONCERNED THAT IT CAN OCCUR UNDER MORE THAN ONE CONDITION. UNLESS THE CODE COMES UP 11273 AS THE PROBLEM, THEY WILL TAKE NO RESPONSIBILITY TO FIX IT EVEN THOUGH THE CODE 1682 PRODUCES THE SAME SITUATION CAUSING THE MALFUNCTION LIGHT TO COME ON AND STAY ON AND THE MESSAGE ENGINE REDUCED POWER TO APPEAR AND THE ENGINE RUNS ROUGH OR WON'T START AT ALL. *TR
