1999 Chevrolet Silverado Engine Problems

BRAKES: SINCE APPROXIMATELY 136,000 MILES TO PRESENT MILES, THE VEHICLE HAS EXHIBITED AN ABS AND BRAKE WARNING LIGHT INTERMITTENTLY ON THE DASH. THIS IS A KNOWN GM ISSUE THAT WAS RECALLED IN CERTAIN STATES, BUT NOT ALL. IT STEMS FROM FAULTY SOLDERING POINTS IN THE ABS CONTROL MODULE AND CAN AFFECT THE VEHICLES ABILITY TO STOP CORRECTLY WHICH COULD RESULT IN AN ACCIDENT. ENGINE/ EMISSIONS: THE PASSENGER SIDE EXHAUST MANIFOLD BOLT HAS BROKEN OFF. THIS IS A KNOWN ISSUE WITH THIS 5.3L ENGINE AS WELL AS THE 4.8L AND 6.0L ENGINES. GM HAS FAILED TO RECALL IN SPITE OF HAVING THOUSANDS OF COMPLAINTS. THE ISSUE CAN CAUSE FAILED EMISSIONS AND POTENTIALLY ENGINE FIRES. ENGINE: AS OF 164,000 MILES, THE ENGINE IS EXPERIENCING LOUD "PISTON SLAP". THIS IS A KNOWN ISSUE WHICH GM ADDRESSED THROUGH REDESIGN IN LATER MODELS. IT LEADS TO EXCESSIVE ENGINE WEAR AND POTENTIAL ENGINE FAILURE. IT APPEARS TO BE A FACTORY DEFECT, YET GM HAS CLAIMED IT IS NOT IMPORTANT DESPITE NUMEROUS COMPLAINTS FROM CUSTOMERS THAT THE ENGINES HAVE REQUIRED REPLACEMENT AS A RESULT. *TR

STARTED MY TRUCK ONE DAY AND HEARD A NOISE I HAVEN'T HEARD BEFORE. LOOKED UNDER HOOD TO SEE WHERE IT WAS COMING FROM AND NOTICED NOISE WAS COMING FROM THE EXHAUST MANIFOLD. THE BOLTS HAVE BROKEN OFF LEAVING THE MANIFOLD LEAKING EXHAUST FUMES. CAME TO FIND OUT THAT THIS IS A COMMON BUT VERY DANGEROUS PROBLEM ON CHEVY TRUCKS. MANY CHEVY VEHICLES HAVE THIS ISSUE AND IF NOT CORRECTED COULD LEAD TO MORE ENGINE TROUBLES OR WORSE YET A FIRE.SO NOW MY VEHICLE IS A SAFETY HAZARD! CHEVY SHOULD RECALL THIS SAFETY HAZARD, WHICH COULD BECOME DANGEROUS. *TR

THE HEAD GASKET ON THE MOTOR LEAKS ANTIFREEZE. THIS HAS BEEN NOTED SEVERAL TIMES ON VEHICLES THAT USE THE EXTENDED LIFE ANTIFREEZE. THE COST TO FIX THE PROBLEM IS NOT CHEAP DUE TO THE COST OF LABOR REQUIRED TO REMOVE THE HEAD FROM THE MOTOR AND REPLACE WITH NEW SEAL. *NM

I HAVE A 1999 CHEVY SILVERADO THAT HAS BEEN DIAGNOSED WITH PISTON SLAP. THIS ALL STARTED SHORTLY AFTER I PURCHASED THE VEHICLE IN 1999. HOWEVER, THE DEALER REFUSED TO FIX IT, STATING THAT IT IS NORMAL NOISE. (NORMAL? THEN WHY DIDN'T THE ENGINE MAKE THIS NOISE WHEN I FIRST DROVE IT OFF THE LOT)? I CONTINUED ASKING THE DEALER ABOUT THE NOISE BUT THEY CONTINUED TO SAY THAT IT WAS NORMAL NOISE. FINALLY, I TOOK THE VEHICLE TO ANOTHER GM DEALER ON APRIL, 2004. THE VEHICLE HAD 48,799 MILES. I ASKED THE MECHANIC AND SERVICE REPRESENTATIVE TO LISTEN TO THE ENGINE, BOTH DETERMINED THE NOISE WAS NOT NORMAL, AND NEEDED REPAIRED. THEY PERFORMED NUMEROUS ENGINE REPAIRS THAT SEEMED, AT THAT TIME, TO MAKE THE NOISE GO AWAY. IN JUNE, 2004, THE VEHICLE NOW HAD 49,023 MILES, THE NOISE HAD RETURNED, AND THE GM DEALER AGAIN STATED THE NOISE WAS NOT NORMAL. THEY THEN REPLACED THE LONG BLOCK OF THE ENGINE, THAT SEEMED TO HAVE TAKEN CARE OF THE PROBLEM. AS OF THIS DATE, THE VEHICLE IS BACK AT THE GM DEALERSHIP WITH THE SAME ENGINE NOISE, WHICH IS A LOUD TICKING/KNOCKING NOISE. I AM, AGAIN, BEING TOLD IS "NORMAL" FOR THIS ENGINE. (THIS IS STATEMENT IS BEING QUOTED BY GENERAL MOTORS, AS BEING "NORMAL". INITIALLY, WHEN I RECENTLY TOOK THE VEHICLE TO THE GM DEALERSHIP, THE SERVICE TECHNICIANS INDICATED THE NOISE WAS NOT NORMAL...UNTIL THE ENGINEERS AT GENERAL MOTORS CONVEYED THE NOISE AS BEING "NORMAL".)

I HAVE A LOUD TICING NOISE COMING FROM THE LEFT REAR OF THE ENGINE. WHILE I WAS PULLING MY 5TH WHEEL THE NOISE KEPT GETTING LOUDER AND LOUDER AND HAD LOSS OF POWER. BY THE TIME WE GOT TO THE CAMP GROUND IT SOUNDED LIKE I HAD LOST MY MUFLER. WE TOOK IT TO MUFFLER MAN OF LUDINGTON AND THEY DISCOVERED THAT 4 EXHAUST MANIFOLD BOLTS HAD SHEARED OFF, 2 ON LEFT YEAR AND 2 ON RIGHT REAR OF BOTH MANIFOLDS. THEY TOOK THE MANIFOLDS OFF AND REPLACED ALL THE BOLTS WITH NEW ONES EXCEPT FOR THE VERY LEFT REAR WAS SHEARED OFF FLUSH AND COULD NOT GET A DRILL IN TO DRILL OUT AND TAP. IN ORDER FOR THEM TO GET THIS OUT THEY WOULD HAVE TO PULL THE HEAD WHICH WOULD HAVE COST $1000.00. THEY PUT IT BACK TOGETHER AND THE TIC WAS GONE. THIS ONLY COST ME 6 HOURS OF VACATION WITH MY FAMILY AND $200.00. THE TIC HAS RETURNED.*AK

THIS COST 448.78. ALSO PO300 MISFIRE #7 CYLINDER REPLACE INJECTOR AND FUEL PRESSURE REGULATOR AND CODE PO463 FUEL LEVEL SENSOR NEEDS FUEL SENSOR REPLACED AT A COST OF 301.00.

THE GAS PEDAL STICKS. I HAVE TO CLEAN MY THROTTLE BODY OUT WITH CLEANER ABOUT EVERY 1000 MILES. EVEN AFTER A CLEANING IT STILL STICKS A LITTLE. THIS IS A SAFETY CONCERN, BECAUSE I HAVE TO USE MORE PRESSURE ON THE GAS PEDEL, THEN IT UNSTICKS AND THE TRUCK LURCHES FOWORD WITH NO CONTROL.*AK
