2001 Chevrolet Prizm

2001 CHEVY PRISM; CHECK ENGINE LIGHT CONTINUES TO BE ON. I HAVE PUT TWO OXYGEN SENSORS ON AT A COST OF OVER $200.00, AND LIGHT STILL COMES ON. MECHANICS TELL ME THE CODE SAYS "LEAN MIXTURE" BUT DON'T KNOW WHAT IS CAUSING IT. CAR HESITATES WHEN COLD, ALMOST THROWING YOU INTO THE WINDSHIELD, UNLESS YOU REPEATEDLY PUMP THE ACCELERATOR. MECHANICS TOLD ME THAT MAYBE FUEL PUMP IS GOING BAD, BUT IT'S BEEN THREE YEARS NOW, AND THIS HASN'T HAPPENED. THE HEAD LINER IN VEHICLE HAS TOTALLY TORN AND DISINTEGRATED, EVEN THO IT HAS BEEN GARAGE KEPT. GM WILL NOT EVEN CONSIDER INVESTIGATING THIS PROBLEM. NO MORE CHEVY'S FOR ME!! THE HESITATION IN TRAFFIC COULD CREATE A REAL SAFETY ISSUE. *TR

I OWN A 2001 CHEVY PRISM LSI. IT HAS ALWAYS EXPERIENCED A NUMBER OF ANNOYING ISSUES THAT I'VE HAD MECHANICS INSPECT/DIAGNOSE THAT NEVER SEEMS TO GET CORRECTLY DIAGNOSED. IT USES ABOUT A QUART OF OIL A MONTH (BUT NEVER SMOKES OUT OF THE EXHAUST PIPE), HAS ALWAYS HAD A HESITATION PROBLEM, AND HAS A WEIRD PROBLEM WITH NOISY 'EXHAUST' SOUNDS THAT SOUND LIKE THEY ARE COMING FROM THE FRONT OF THE CAR AND ARE WORSE (VERY LOUD) IN WET CONDITIONS. UPON COLD START, THE ENGINE HESITATES PRETTY BADLY WHEN PRESSING THE ACCELERATOR PEDAL. THE HESITATION GETS MUCH BETTER ONCE THE ENGINE HAS WARMED UP, BUT STILL HAS MINOR HESITATION UPON INITIALLY PRESSING THE ACCELERATOR PEDAL. MECHANICS HAVE SAID THEY THINK THE FUEL PUMP MAY BE STARTING TO GO OUT (I WAS TOLD THAT 5 YEARS AGO AND IT HAS NEVER GONE OUT) AND THEY SAID THERE WAS A 'LEAN MIXTURE CODE' WHEN MY CHECK ENGINE LIGHT WAS ON AT ONE POINT BUT WERE UNABLE TO DETERMINE WHAT THE OFFICIAL CAUSE OF THAT CODE WAS AND IMPLIED IT WAS PROBABLY THE FUEL PUMP SLOWLY GOING BAD. THEY RAN A CARBON CLEAN WHICH SHUT OFF THE SERVICE ENGINE LIGHT BUT THE HESITATION AND OIL CONSUMPTION HAS ALWAYS REMAINED. NUMEROUS TIMES, THE HESITATION HAS BEEN AN ISSUE IN TRAFFIC WHEN I PRESS THE ACCELERATOR PEDAL AND THE ENGINE DOES NOTHING UNTIL I PUMP THE PEDAL A FEW TIMES TO GET IT GOING...LEADING TO A POSSIBLY SAFETY HAZARD IN CERTAIN TRAFFIC CONDITIONS. NOBODY HAS BEEN ABLE TO FIGURE OUT WHY IT HESITATES AND FIX THE HESITATION PROBLEM AND I'VE READ THIS IS A VERY COMMON PROBLEM ALONG WITH THE OIL CONSUMPTION PROBLEM FOR CHEVY PRISMS/TOYOTA COROLLAS (ESPECIALLY THE 2001 MODEL). MECHANICS HAVE ALSO INSPECTED MY EXHAUST SYSTEM TO TRY TO FIND THE ISSUE WITH THE NOISY EXHAUST BUT HAVE FOUND NO LEAKS. I'M HOPING A RECALL CAN BE ISSUED TO HELP FIX SOME OF THESE ISSUES SINCE MECHANICS CAN'T SEEM TO FIGURE OUT THESE COMMON PROBLEMS. IT SEEMS THAT TOYOTA AND GM ARE BOTH AWARE OF MOST OF THESE ISSUES AND HAVE DONE NOTHING TO RESOLVE THEM. *TR

TL*THE CONTACT OWNS A 2001 CHEVROLET PRIZM. THE CONTACT STATED THAT THE CHECK ENGINE INDICATOR WOULD NOT STOP ILLUMINATING ON THE INSTRUMENT PANEL. WHENEVER THE VEHICLE WOULD APPROACH A STOP, IT WOULD STALL. THE DEALER AND SEVERAL LOCAL REPAIR SHOPS PERFORMED A DIAGNOSTIC, BUT WERE UNABLE TO FIND A DEFECT. THE VEHICLE HAS BEEN EXPERIENCING THE SAME FAILURE FOR THE PAST THREE YEARS. RECENTLY, THE CONTACT DROVE TO A LOCAL REPAIR SHOP AND THE MECHANIC STATED THAT THE SPARK PLUGS AND OXYGEN SENSOR WERE DEFECTIVE; HOWEVER, ONLY THE SPARK PLUGS WERE REPLACED. IMMEDIATELY FOLLOWING THE REPAIRS, THE FAILURE RECURRED. THE CURRENT MILEAGE WAS 75,000 AND FAILURE MILEAGE WAS 45,000.

EXCESSIVE OIL CONSUMPTION (ONE QUART LOW EVERY 300-400 MILES), WORSENING, APPEARS TO BE KNOWN DEFECT FOR TOYOTA SUPPLIED ENGINES IN 2001 CHEVROLET PRIZM AND POSSIBLY OTHER YEARS OF THIS MOTOR TYPE (POSSIBLE FACTORY RING, VALVE EARLY FAILURE ISSUES), NO LEAKS OR HEAVY SMOKE APPARENT, AIR FILTER NORMAL WITH NO APPARENT BLOW-BY FROM RINGS AT THAT POINT. REGULAR OIL AND FILTER CHANGES, CAR DRIVEN DAILY FOR LOCAL USE, NO OTHER KNOWN DEFECTS OR RECURRING PROBLEMS, CAR OPERATES NORMALLY OTHER THAN HIGH OIL AMOUNTS USED. *TR

I OWN A 2001 AND A 2002 CHEVY PRIZM. BOTH CARS ARE USING EXCESSIVE OIL (SEVERAL QUARTS EVERY 100 MILES EACH). DEALER STATES THIS IS A COMMON PROBLEM DUE TO CARBON BUILDUP IN THE CYLINDERS. EXCESSIVE OIL CONSUMPTION STARTED AROUND 50,000 MILES. THE CHEVY PRIZM IS REALLY A TOYOTA COROLLA. TOYOTA HAS HAD THIS PROBLEM AND HAS WARRANTED THE REPAIR. GENERAL MOTORS IS NOT ASSISTING ITS CUSTOMERS WITH THE REPAIR. I GUESS THAT IS WHY TOYOTA IS NUMBER ONE CAR MAKER AND GM IS NUMBER 2. I WILL NEVER BUY ANOTHER GM PRODUCT AGAIN. *JB
