2001 NISSAN MAXIMA Vehicle Speed Control Problems

CHECK ENGINE LIGHT CONTINUES TO COME ON. IDENTIFIED THAT THE IDLE CONTROL VALVE AND GASKET NEED TO BE REPLACED. IDENTIFIED ALSO THAT ECM IS NOW BURNED OUT. *TR

I WAS AT A RED LIGHT, WHEN IT TURNED GREEN I PUSHED THE GAS PEDAL AND IT WOULD GO. I HAD TO USE EXTREME FORCE FOR THE CAR TO GO. EVER SINCE FEBRUARY 2014, ITS BEEN HAPPENING EVERY DAY. I'M SCARED THE GAS PEDAL'S GOING TO GET STUCK AND ILL CRASH. WHEN I TURN I HEAR A KNOCKING NOISE COMING FROM THE TIRE/SUSPENSION. *TR

I BOUGHT A 2001 NISSAN MAXIMA BRAND NEW IN JUNE 2001. ONE DAY WHILE DRIVING IN 2004 I EXPERIENCED SUDDEN ACCELERATION AND THE ENGINE RACING. IT DID STOP AFTER A FEW SECONDS BUT I TOOK IT IMMEDIATELY TO MY NEIGHBORHOOD CAR MECHANIC. HE COULDN'T DUPLICATE THE PROBLEM BUT FOUND A DEFECTIVE AIR POLLUTION PART AND REPLACED IT. THE NEXT DAY, WHILE WAITING TO TAKE A LEFT TURN AT AN INTERSECTION, THE ENGINE SUDDENLY RACED AGAIN AND WITH ME PRACTICALLY STANDING ON THE BRAKE WE SLID ACROSS THE INTERSECTION HEADED TOWARDS ONCOMING TRAFFIC. LUCKILY PEOPLE SLOWED ENOUGH FOR ME TO SLIDE ACROSS THE INTERSECTION WITH RUBBER BURNING, ENGINE WHINING, ETC. A FEW SECONDS LATER IT STOPPED. I WAS ONLY ABOUT A MILE FROM THE DEALER THAT I HAD PURCHASED IT FROM SO I IMMEDIATELY DROVE THERE AND PULLED INTO THE SERVICE DEPT. AREA. I EXPLAINED THE PROBLEM AND THEY TOLD ME...

WE OWN A 2001 NISSAN MAXIMA, WHICH WE PURCHASED NEW FROM A NISSAN DEALER. IT HAS, ON 3 OCCASIONS, EXPERIENCED A PROBLEM WITH "SURGING"/HIGH REVVING.*DT THE CAUSE IN EVERY CASE HAS BEEN A PART KNOWN AS AN "IDLE AIR CONTROL VALVE" (IACV), WHICH FAILS AND IN DOING SO, CAUSES THE "ECM" (THE "ENGINE COMPUTER") TO FAIL. WE HAVE DISCOVERED THAT HITACHI IS THE SOLE SOURCE FOR THE IACV, WHETHER THE PART IS OBTAINED FROM A NISSAN DEALER OR ANY OTHER SOURCE UNDER ANY OTHER BRAND. THIS ISSUE IS APPARENTLY A PARTICULARLY WELL-KNOWN ISSUE WITH THIS MODEL SERIES OF VEHICLE, BOTH NISSAN AND INFINITI. THE FIRST TIME THE VEHICLE HAD THIS ISSUE, IT WAS UNDER WARRANTY AND WAS SUPPOSEDLY REPAIRED BY NISSAN. HOWEVER, THE SAME ISSUE HAS RECURRED ON 2 SUBSEQUENT OCCASIONS, AND BOTH TIMES NISSAN HAS WHOLLY FAILED TO ADDRESS THE ISSUE. WE HAVE REPEATEDLY ATTEMPTED TO ADDRESS THIS ISSUE...

TL*THE CONTACT OWNS A 2001 NISSAN MAXIMA. AFTER HAVING THE CHECK ENGINE LIGHT REPAIRED, IT CONTINUED TO ILLUMINATE. HE ALSO EXPERIENCED UNINTENDED ACCELERATION WHILE DRIVING APPROXIMATELY 35 MPH. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHO INFORMED HIM THAT THEY WOULD RUN A DIAGNOSTIC TEST FOR TWO DAYS. THE VIN WAS NOT AVAILABLE. HE NISSAN MANUFACTURER HAVE NOT BEEN CONTACTED. THE FAILURE MILEAGE WAS 95,000.

TL*THE CONTACT OWNS A 2001 NISSAN MAXIMA. THE VEHICLE HAS HAD SEVERAL 02 SENSORS REPLACED ON THE VEHICLE. THE CATALYTIC CONVERTER WAS REPLACED AROUND 60,000 MILES AND AGAIN AT 120,000 MILES. WHEN TURNING ON THE VEHICLE, THE OVERDRIVE LIGHT ILLUMINATES AND FLASHES INTERMITTENTLY. AFTER ATTEMPTING TO ACCELERATE FROM A STOP, THE VEHICLE WOULD ONLY TRAVEL 5 MPH. THE VEHICLE HAD TO BE PULLED OVER AND RESTARTED FOR THE SPEED TO OPERATE NORMALLY. THE CURRENT MILEAGE IS 150,000 AND FAILURE MILEAGE WAS 40,000.

WHILE DRIVING AT APPROXIMATELY 30 MPH AND DECELERATING THE CAR BEGAN TO SLIGHTLY BUCK WHEN THE TRANSMISSION TRIED TO DOWN SHIFT. AFTER APPROXIMATELY ONE TO TWO MINUTES I SMELLED AN ELECTRICAL BURN. WHEN I CAME TO A STOP AND PUT THE CAR IN PARK THE ENGINE RACED TO APPROXIMATELY 1600 TO 1900 RPMS AT IDLE. THE OBD-II INDICATED CODES OF P0505: IDLE AIR CONTROL VALVE AND P0420: THREE WAY CATALYST FUNCTION. MY LOCAL MECHANIC INSPECTED THE CAR AND REPLACED THE FAULTY IDLE AIR CONTROL VALVE. HE CONTACTED THE LOCAL NISSAN SERVICE SHOP, AND THEY INFORMED HIM THAT IDLE AIR CONTROL VALVE FAILED AND SHORTED THE ENGINE CONTROL MODULE, ECM. THIS SEEMED TO BE A COMMON PROBLEM THE DEALER NOTED, AND CURRENTLY HAD ANOTHER 2001 MAXIMA IN THE SHOP THAT WAS EXHIBITING THE SAME FAILURES. THE DEALER INSPECTED MY CAR AND REPORTED THE IDLE AIR CONTROL VALVE FAILED AND SHORTED THE...

DT*: THE CONTACT STATED WHILE DRIVING 70 MPH ON INTERSTATE DURING DRY CONDITIONS, THE VEHICLE STALLED WITHOUT WARNING REDUCING TO 30 MPH. THE VEHICLE WAS PULLED OFF OF THE INTERSTATE. AFTER SITTING FOR A WHILE AND RESTARTING THE VEHICLE, THE VEHICLE RAN NORMALLY. THIS OCCURRED INTERMITTENTLY. AT TIMES THE VEHICLE WOULD REDUCE IN SPEED AND OTHER TIMES THE VEHICLE WOULD STALL. DURING EACH INCIDENT, THE CHECK ENGINE LIGHT ILLUMINATED. BOTH THE INDEPENDENT MECHANIC AND THE DEALERSHIP WERE UNABLE TO DUPLICATE THE PROBLEM.

VEHICLE SPEED DIAL INDICATOR STOPPED WORKING. THE DEALERSHIP INDICATED THIS COULD BE AS A RESULT OF A SENSOR FAILURE.*AK

AFTER PARKING VEHICLE, CONSUMER SHIFTED TO PARK, INSTANTLY VEHICLE SURGED FORWARD AND HIT THE GARAGE WALL. DAMAGE WAS $5000.00. VEHICLE HAS BEEN REPAIRED AT BODY SHOP, NOT INSPECTED BY DEALER.*AK *YD
