1994 CHEVROLET S10 BLAZER.

I WAS NEVER NOTIFIED OF A RECALL ON MY VEHICLE. I NOTIFIED THE COMPANY AFTER MY MECHANIC INFORMED ME ABOUT THE RECALL. THE RECALL HAD EXPIRED, BUT SINCE I NEVER RECEIVED THE INFORMATION, I NOTIFIED THEM, AND ONLY ASK FOR REIMBURSEMENT OF THE FINAL REPAIRS. I FELT IT WAS THERE RESPONSIBILITY, BECAUSE OF THE FAILURE TO NOTIFY ME. *TR

WHILE DRIVING,A GAS SMELL WAS COMING IN FROM THE VENTS. THE DRIVER NOTICED THAT A LIQUID WAS ON THE GROUND COMING FROM UNDERNEATH THE VEHICLE. THE DRIVER WAS ABLE TO DRIVE IT TO THE DEALER FOR INSPECTION. THE MECHANIC INFORMED THE DRIVER THAT THE FUEL RAIL NEEDED REPLACEMENT. *NM THE INJECTORS LEAKED GAS. *SC

STALLS ABOUT EVERY HALF A MILE. GOING ON ABOUT 1 1/2 WEEKS. DONE QUITE A BIT OF RESEARCH TURNING UP MANY COMPLAINTS ABOUT FUEL PUMPS AND EGR VALVES. I DON'T HAVE MONEY FOR REBUILDING MY ENGINE SO I'D LIKE TO FIND OUT IF THERE HAS BEEN CONFIRMED ANSWER AS TO WHY THESE BLAZERS ARE STALLING. *JB

1ST ISSUE; IN SEPT/2000 I WROTE A LETTER TO NHTSA ABOUT HAVING TO REPLACE THE CFI UNIT. FROM WHAT I UNDERSTAND, THE CFI UNIT HAS BEEN RE-ENGINEERED BECAUSE OF MANY FAILURES. THE OEM UNIT COULD CAUSE CYLINDER WALL DAMAGE, FUEL CAN LEAK INTO THE OIL SUMP, POSIBLE ENGINE FIRE AND SHORTENED ENGINE LIFE. I FEEL GM SHOULD BE RESPONSIBLE FOR REPLACING THIS UNIT AT FULL COST. 2ND ISSUE: MY BLAZER STARTED PEELING PAINT ON THE HOOD IN 2001. IS THEIR ANYTHING I DO TO GET GM REPAINT MY BLAZER? 3RD ISSUE; IN FEB/2003 MY \\\\\\"ANTILOCK BRAKE LIGHT\\\\\\" THAT\\\\\\'S ON THE INSTRUMENT PANEL, COMES ON WHEN THE VEHICLE REACHES A SPEED OF ABOUT 18 - 20 MPH AND GOES OUT WHEN THE VEHICLE SLOWS BELOW THIS SPEED. WHEN THE ENGINE IS STARTED, IT GOES THOUGH A NORMAL CHECK OF SYSTEMS, THE LIGHT IS ON FOR A SHORT TIME AND GOES OUT, BUT COMES ON WHEN YOU REACH A SPEED OF 18 - 20 MPH. I\\\\\\'VE TAKEN THE BLAZER TO A GM DEALER FOR REPAIR BUT THE MECHANIC CAN\\\\\\'T FIGURE IT OUT. HE CLEARS ALL CODES BUT IT DOESN\\\\\\'T FIX THE PROBLEM. THE DEALER HASN\\\\\\'T CHARGED ME ANY MONEY FOR HIS TIME TO DATE.

EGR VALVE MAKES CAR SURGE AND DIE ALMOST EVERY YEAR AND WE HAVE TO PAY SEVERAL HUNDRED TO CHANGE IT OUT EACH TIME. ($50+ JUST TO GET THE CAR CHECKED BY THEM SO THEY CAN TELL ME ITS A CODE 32-BAD EGR THEN 2-3 HUNDRED FOR PART AND LABOR). OF COURSE I STOPPED USING THE DEALERSHIPS AND WENT TO A SMALL BUSINESS MECHANIC AND CUT $100 OFF THAT. THE OTHER PROBLEM IS THE FUEL PUMP HAS GIVEN OUT TWICE BUT MY SON HAS FIXED IT EACH TIME FOR ME.

REPLACED SPIDER INJECTOR ONCE, REPLACED EGR VALVE 4 TIMES, REPLACED BOTH EXHAUST MANIFOLDS. THE SERVICE REP TOLD ME THE EGR VALVE REPLACEMENT IS A VERY COMMON PROBLEM. I CHECKED WITH A DEALER AND APPARENTLY THERE IS NO RECALL ON THE SPIDER INJECTOR NOR EGR VALVES WHICH TO ME IS A VERY DANGEROUS SITUATION WHEN DRIVING AND THE MOTOR STARTS SURGING AND DYING.*AK

ENGINE FAILED DUE TO A FAULTY REGULATOR ON NEWLY INSTALLED CPI, WHICH LEAKED FUEL INTO THE ENGINE AND PRESENCE OF SILICON IN THE ENGINE FROM INSTALLATION OF GASKETS, OIL CHANGE NOT PERFORMED ON VEHICLE WHEN NEW FUEL INJECTION/CPI AND GASKETS WERE REPLACED, THIS ALLOWED FUEL, DEBRIS, ETC TO CONTAMINATE THE ENGINE, ENGINE REPLACEMENT COMPELETED 1/26/01.

I HAVE REPLACED THE EGR VALVE 3 TIMES ON THIS VEHICLE. I AM HAVING TROUBLE WITH THE VEHICLE RUNNING ROUGH. I WAS TOLD I HAVE ALOT OF CARBON BUILDUP AROUND THE EGR PORTS AND THIS IS BREAKING/FLAKING OFF. THE DEALER SAID THEY WOULD HAVE TO TAKE THE CYLINDER HEADS AND INTAKE MANIFOLD GASKET AND SUBMERGE IN A HOT TANK OF ACID TO CLEAN THE CARBON OFF THESE PARTS. THE REPAIR QUOTE WAS $1600.00 AND THERE WAS NO QUARANTEE HOW LONG THIS WOULD TAKE CARE OF THE PROBLEMS I AM HAVING WITH THIS VEHICLE.

EGR VALVE REPARIED SEVERAL TIMES ALSO, . FUEL PUMP REPLACED. *AK

THE VEHICLE STALLED ON THE HIGHWAY SEVERAL TIMES DUE TO FUEL INJECTION PUMP FAILURE. YH

DUE TO CRACKS AND RUST IN THE SEAMS OF THE FUEL TANK, LEAKAGE OCCURS. DEALERSHIP ADVISED THAT THIS IS A COMMON OCCURENCE. *AK *ML

I EXPERIENCED "HARD STARTS" "ENGINE RUN ON" AND "ROUGH IDLE" FOR APPROXIMATELY THREE TO FIVE MONTHS. THE PROBLEM WAS DIAGNOSED AS A LEAKING FUEL INJECTOR. THE GM DEALER GARAGE INFORMED ME THAT THEY "SEE THIS ALL THE TIME WITH GM PRODUCTS" AND THAT THE LEAKING FUEL PRESENTED A SIGNIFICANT FIRE HAZARD. THE GARAGE STATED THAT WHILE GM WILL REPAIR FUEL INJECTORS WITH CALIFORNIA EMISSIONS, THEY WILL NOT DO SO WITH FEDERAL EMISSIONS. GM HAS BEEN NO HELP AND TOLD ME I HAD NO RECOURSE TO RECOVER THE MONEY PAID TO REPLACE THE FUEL INJECTOR (APPOXIMATELY $700). IT SEEMS TO ME IF THE PROBLEM IS COMMON, PRESENTS A SAFETY HAZARD, AND HAS BEEN THE SUBJECT OF AN ACKNOWLEDGED PROBLEM, SOME INVESTIGATION INTO THIS ISSUE SHOULD TAKE PLACE..

WHILE DRIVING VEHICLE WOULD STALL FOR NO REASON. WOULD HAVE NO CONTROL OF VEHICLE. INSTRUMENT PANEL WENT BLACK. TOOK VEHICLE TO DEALER & INFORMED THAT FUEL PUMP RELAY NEEDED REPLACING. POSSIBLE CAUSE OF STALLING. NOT SENDING FUEL THROUGH THE FUEL LINES. ALSO, POSSIBLE ELECTRICAL SHORT, CAUSING INSTRUMENT PANEL TO GO BLANK. *AK
