2003 CHEVROLET SILVERADO 2500 Engine And Engine Cooling Problems

In the middle of the taxiway, while I was traveling my truck turned off while it was running and did not turn on again, putting my safety at risk by being in the middle of the taxiway, after several minutes the truck was able to be removed from the road, then I was able to investigate that I am not the only one that the same thing has happened to him, there is no Safety Recall in this regard, the GM fabric is aware of these cases but only wrote a TSB, it was diagnosed with the scanner and it gave code U1800, before the event there were no lights warning but after the event there is a check engine light on.

THE VEHICLE GOES INTO REDUCED ENGINE POWER WHILE DRIVING. THE ENGINE LOSES POWER TO ABOUT 20 MPH. IF DRIVING 70 MPH IT IS VERY DANGEROUS BECAUSE THE SUDDEN REDUCED ENGINE POWER WILL CAUSE A SEVERE ACCIDENT AND POSSIBLY KILL SOMEBODY. THIS HAS BEEN HAPPENING THE LAST FEW MONTHS. *TR

EXHAUST MANIFOLD BOLTS ARE BROKEN OFF IN BLOCK CAUSING EXHAUST LEAKS AND MANY OTHER PROBLEMS SUCH AS COMPUTER GETTING MIXED SIGNALS, O2 SENSOR AND WILL CAUSE MOTOR TO GO BAD IN TIME. *TR

MY 2003 SILVERADO PICKUP TRUCK HAS BEEN FOUND TO HAVE A COMMON AND RECURRENT PROBLEM. EXHAUST MANIFOLD BOLTS BREAK, AND ON THE DRIVER SIDE REAR, THEY CAN BE EXPENSIVE TO REPAIR. A FEW MINUTES OF WEB SEARCHING ON THIS TOPIC PRODUCED A NUMBER OF RESULTS AND MY CONCLUSION IS THE ISSUE IS COMMON. THE ONLINE COMPLAINTS ALSO INDICATE THAT THE SUCCESS RATE FOR THE REPAIR IS NOT GOOD, WITH MANY REPAIRED VEHICLES HAVING SUBSEQUENT BOLT FAILURES. MY VEHICLE IS IN AN AUTHORIZED CHEVY SERVICE GARAGE HAVING THE BOLTS REPLACED. THE ORIGINAL ESTIMATE WAS FOR $486, IF CYLINDER HEAD DID NOT NEED TO BE REMOVED. THE SERVICE TECHNICIAN BROKE A TAP OFF IN THE REAR MOST BOLT LOCATION. I DON'T KNOW IF IT HAPPENED BEFORE HEAD REMOVAL OR AFTER. IT BECAME NECESSARY TO REMOVE THE CYLINDER HEAD AND WAS REQUOTED AT $1600. A CALL WAS MADE TO GM 3-6-12. THE RESPONSE...

THIS VEHICLE FAILED STATE SAFETY INSPECTION DUE TO CORRODED BRAKE LINES AND LEAKING EXHAUST AROUND HEAD GASKET. *TR

THE HEADS OF THE BOLTS THAT HOLD THE EXHAUST MANIFOLDS TO THE CYLINDER HEADS ARE BREAKING OFF FOR NO APPARENT REASON CAUSING AN EXHAUST LEAK. *TR

I HAVE HAD A EXHAUST LEAK THAT I FINALLY PINPOINTED TO BE BROKEN EXHAUST MANIFOLD BOLTS. THE TRUCK WAS BOUGHT NEW BY ME AND HAS NEVER HAD ANY EXHAUST WORK DONE. NOW I HAVE TO TAKE IT TO A DEALER TO HAVE THIS EXPENSIVE REPAIR DONE. APPARENTLY THIS SEEMS TO BE AN EXTENSIVE PROBLEM, WITH THESE BOLTS. THIS I UNDERSTAND TO BE AN EXTENSIVE REPAIR. GM KNOWS THERE IS A PROBLEM WITH THE BOLTS, WHY WONT THEY MAKE IT RIGHT. *TR

TL*THE CONTACT OWNS A 2003 CHEVROLET SILVERADO 2500 HD. THE CONTACT STATED THAT THE VEHICLE STALLED WITHOUT WARNING WHILE DRIVING AT ANY SPEED INTERMITTENTLY, BUT THE FAILURE BECAME FREQUENT, WHEN THE VEHICLE WAS TURNED OFF AND WITHIN A FEW MINUTES IT BEGAN TO FUNCTION NORMALLY. THE VEHICLE WAS TAKEN TO THE DEALER WHO PERFORMED A DIAGNOSTIC TEST AND CONFIRMED THAT THE CRANK POSITION SENSOR HAD FAILED. THE MANUFACTURER WAS NOTIFIED AND STATED THAT THE VEHICLE WAS NOT INCLUDED IN RECALL 07V521000 ENGINE AND ENGINE COOLING; THEY AGREED TO CALL HIM AT A LATER DATE TO INFORM HIM IF THEY WERE GOING TO ASSIST WITH THE REPAIR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 2,000 AND THE CURRENT MILEAGE WAS 105,000.

VEHICLE REMAINS RUNNING BUT SHOWS POWER REDUCTION. CHECK ENGINE LIGHT COMES ON AND STAYS ON. YOU HAVE TO PULL OVER, SHUT IT OFF, PRESS THE ARROW BUTTON ON THE STEERING WHEEL FOR A FEW SECOND AND RESTART. THIS HAPPENED ON I35 AT 70MPH 4 TIMES IN 40 MILES YESTERDAY. *TR

DT*: THE CONTACT STATED THE VEHICLE WAS STARTED, RAN FOR 10 SECONDS AND STALLED COMPLETELY. THE VEHICLE WAS NOT ABLE TO BE RESTARTED. THE VEHICLE WAS TOWED TO A SERVICE DEALER WHO WAS UNABLE TO DUPLICATE OR DETERMINE THE PROBLEM.
