2005 Hyundai Tucson engine problems

ENGINE

This car accelerates while unattended. Most likely due to an ECM malfunction and unable to properly respond/send signals to the motor. On 4 occasions, the car has accelerated, even if in park. It will go 25mph on its own and to stop I had to put it in neutral. I’ve seen that my car isn’t the only one experiencing this. Considering it’s an ECM issue there should be a recall because that is not a part you change during the life of a car.

INITIAL ISSUES ON VEHICLE PRESENTED IN JANUARY 2021 WITH VARIOUS CHECK ENGINE LIGHT CODES INCLUDING P0133. ALTHOUGH VEHICLE PASSED EMISSIONS IN 2020, VARIOUS CHECK ENGINE CODES FOR MASS AIR FLOW SENSOR, OXYGEN SENSORS, MISFIRE FOR VARIOUS CYLINDERS. AFTER REPLACING INDICATED MASS AIR FLOW SENSOR, OXYGEN SENSORS INDICATED VIA OBD II TOOL, BATTERY, ALTERNATOR (MORE THAN ONCE), BOTH FRONT CV BOOTS, HEAD GASKET SEALS FOR BOTH CYLINDER BANKS, MORE CHECK ENGINE LIGHT ISSUES APPEAR ACCORDING TO THE VEHICLE. CURRENTLY ANOTHER CYLINDER MISFIRE CHECK ENGINE CODE HAS APPEARED AFTER ALL SPARK PLUGS HAVE BEEN REPLACED WITH OEM RECOMMENDED BRAND REPLACEMENTS (NKG PRE-GAPPED SPARK PLUGS). THE MISFIRE CODE HAS CLEARED AT THIS TIME. THE CURRENT CHECK ENGINE CODE FROM THE OBD II TOOL IS ERROR CODE FOR DRIVE TRAIN DRIVEABILITY P0420 REGARDING CATALYST SYSTEM OPERATING BELOW THRESHOLD AT BANK 1. I HAVE UTILIZED LOCAL STORE CATALYTIC CLEANER LIQUIDS TO CLEAN THE SYSTEM, WHICH HAS NOT RESOLVED THIS ISSUE. ADDITIONALLY, BEGINNING IN JANUARY 2021, THE VEHICLE WAS TAKEN TO THE CLOSEST LOCAL DEALSHIP FOR A LARGE MAJORITY OF THESE REPAIRS INCLUDING A $150 DEALERSHIP FEE JUST TO HAVE THESE CODES REVIEWED AND ADDITIONAL FEES FOR THE LABOR TO ADDRESS FOR EACH ISSUE FOR EACH REPAIR.

ENGINE

THE FIRST TIME THIS HAPPENED I WAS PULLING INTO A PARKING PLACE IN A SHOPPING CENTER. AS I WAS TURNING INTO THE PARKING PLACE I VERY LIGHTLY TAPPED THE ACCELERATOR AND THE ENGINE REVED UP AND I APPLIED THE BRAKE ONLY TO HAVE THE CAR CONTINUE FORWARD AND GO UP THE CEMENT CURB. I THEN PUSHED DOWN ON THE BRAKE PEDAL AS HARD AS I COULD AND ONLY THEN DID THE CAR STOP. IF THE CEMENT BLOCK HAD NOT BEEN THERE, I WOULD HAVE HIT THE CAR PARKED DIRECTLY IN FRONT OF ME. THE FRONT TIRES HAD GONE ABOUT TWO FEET UP ON THE CEMENT BLOCK. THE NEXT TIME THIS HAPPENED I WAS ONCE AGAIN PARKING. THIS TIME I WAS PARKING PARALLEL TO THE CURB. I PULLED INTO AND IN FRONT OF THE SPACE I WAS GOING TO PARK IN. I PUT THE CAR IN REVERSE AND BEGAN TO BACK UP SLOWLY WITH MY FOOT OVER THE BRAKE PEDAL. SUDDENLY, THE ENGINE REVED UP AND THE CAR LURCHED BACKWARD. THIS TIME I APPLIED THE BRAKE VERY HARD AND I WAS ABLE TO STOP MY CAR BEFORE I HIT CAR IN BACK OF ME.

I WAS SLOWING TO A STOP AND COULD FEEL THAT THE CAR WAS GOING TO DIE AND IT DID. I TOOK IT TO THE DEALER AND THEY DID A FUEL INDUCTION SERVICE AND IT SEEMED TO FIX THE PROBLEM.THE DEALER SHOULD HAVE NOT CHARGED ME FOR A CAR SO NEW, BUT THEY PUT UNDER THE SERVICE "MAINTENANCE" WHICH I DIDN'T FIND OUT TILL A COUPLE YEARS LATER WHEN IT HAPPENED AGAIN AND I CALLED THE DEALERSHIP. I HAVE SINCE HAD THE SAME INCIDENT HAPPEN 5 TIMES AND AFTER READING SEVERAL PEOPLE HAVE HAD THE SAME THING WITH NO EXPLANATION I DECIDED TO PUT MY INCIDENTS IN SO THAT MORE PEOPLE WOULD KNOW IT ISN'T JUST A SINGLE HAPPENING OF THE SAME THING. AFTER THIS HAPPENS I TAKE THE CAR ON THE FREEWAY AND FLOOR IT MEANING TO BLOW OUT WHAT I THINK MAY BE STUCK IN THE FUEL LINE???? IT ALWAYS WORKS FOR A WHILE. THIS THING DOESN'T OCCUR FOR ANY PARTICULAR REASON AND I HAVE THE CAR WELL MAINTAINED. I NOW HAVE OVER 120,000 MILES AND THE LAST TIME IT DID THIS WAS ABOUT 6 MONTHS AGO. THANK GOODNESS NOTHING BAD HAS HAPPENED BECAUSE OF IT.

ENGINE

ENGINE ON OUR 2005 HYUNDAI TUCSON TURNED OFF IN THE MIDDLE OF A BUSY HIGHWAY GOING APPROXIMATELY 40 MPH. MANAGED TO TURN/ROLL OFF THE ROAD WITHOUT POWER OR POWER STEERING. HAD TO RESTART CAR SEVERAL TIMES AS IT WOULD STALL OUT ON ACCELERATION OR WHEN SLOWING TO TURN. PAID DEALERSHIP $209 TO "FIX" THE PROBLEM, BUT THE PROBLEM STILL EXISTS A MONTH LATER AND IS GETTING PROGRESSIVELY WORSE EACH DAY. DEALERSHIP DID OIL CHANGE, VEHICLE INSPECTION AND REPLACED "P0444 EVAP PURGE CONTROL VALVE CONNECTOR." CLEARLY THIS DID NOT SOLVE THE PROBLEM AS THIS SEVERE SAFETY HAZARD PERSISTS. HYUNDAI HAS NO ANSWERS AND SEVERAL OTHER SIMILAR COMPLAINTS WE'VE READ HAVE BEEN FILED WITH THE NHTSA. SOMETHING HAS GOT TO BE DONE.

WHILE STOPPED AT A LIGHT THE ENGINE REVVED UP TO A HIGH RATE. I TRIED TO PUT THE TRANSMISSION INTO NEUTRAL BUT PUT IT INTO REVERSE INSTEAD, THE HIGH RATE OF REVS CONTINUED, FINALLY GOT IT INTO NEUTRAL AND ENGINE WENT BACK TO NORMAL IDLE SPEED. WHEN LIGHT CHANGED PUT TRANSMISSION INTO DRIVE AND PROCEEDED HOME (A FEW BLOCKS) WITHOUT INCIDENT. THIS HAPPENED ABOUT 13 MONTHS AGO WHEREBY THE MECHANIC REPLACED THE IDLE SPEED CONTROL AND THROTTLE POSITION SENSOR. ALSO THEY DID A THROTTLE BODY AND FUEL INJECTION SERVICE AT THAT TIME.

ENGINE

VEHICLE WAS TRAVELING AT APPROXIMATELY 40 MPH WHEN THE VEHICLE SUDDENLY STOPPED RUNNING AND BLOCKED THE CENTER LANE OF TRAFFIC ON A BUSY THOROUGHFARE DURING RUSH HOUR. ATTEMPTS TO RESTART THE VEHICLE WERE UNSUCCESSFUL AT FIRST. AFTER 15 MINUTES VEHICLE WAS ABLE TO START AND STAYED RUNNING. THIS TYPE OF INCIDENT HAS ALSO HAPPENED IN THE PAST - VEHICLE WILL BE TRAVELING AT SPEED AND WILL JUST SUDDENLY SHUT OFF AND NOT RESTART. VEHICLE HAS BEEN TAKEN TO A SERVICE SHOP TO BE EVALUATED. VEHICLE HAS A NEW COIL PACK, PLUGS, WIRES, THROTTLE POSITION SENSOR, A/C COMPRESSOR, AND TIMING BELT. VEHICLE, ONCE REPAIRED, IS GOING BE SOLD DUE TO ITS CONTINUED UNRELIABILITY AND TENDENCY TO JUST STALL AT ANY TIME AT ANY SPEED.

MISFIRE CYLINDER #5. THIS HAS BEEN AN ONGOING PROBLEM SHORTLY AFTER MY MOTHER GAVE ME THE VEHICLE AT APX. 24,000 MILES. THE CAR WAS TRANSPORTED FROM THE EAST COAST HERE TO ARIZONA. IT HAS BEEN IN AND OUT OF HYUNDAI DEALERSHIPS AND STILL NO FIX, WITH MY FATHER PAYING THE BILLS, WHICH IS HARD FOR HIM BEING ON A FIXED INCOME, BUT MY SAFETY AS WELL AS HIS GRAND CHILDREN ARE PARAMOUNT. THE VEHICLE WILL QUICKLY SLOW DOWN FROM A 70 MPH SPEED TO 35MPH WITHOUT WARNING AND SOMETIMES THE ENGINE LIGHT WILL COME ON (CODE P0305). I MADE A COMPLAINT ONCE BEFORE (CASE #389816). THIS CONTINUING PROBLEM WITH NO FIX HAS ME HAVE SEVERAL NEAR MISSES OF A REAR END COLLISION, WHICH SO FAR I HAVE BEEN LUCKY NOT TO HAVE. THE MOST RECENT REPAIR WAS ON JUNE 14TH THRU 15TH, 2013 AND THE PROBLEM WAS BACK ON THE MONDAY AFTER PICKING THE VEHICLE ON SUNDAY, THE 16TH. WHEN THE PROBLEM FIRST HAPPENED THE VEHICLE WAS STILL UNDER THE EXTENDED SERVICE AGREEMENT AND OF COURSE IT'S NOW EXPIRED WILL THE SAME PROBLEM THAT WASN'T RESEARCHED DURING THAT TIME. I HAVE SEEN MANY COMMENTS WITH OWNERS HAVING THE SAME ISSUES ON HYUNDAI'S FORUMS, SO IT'S NOT MY IMAGINATION. CAN SOMEONE PLEASE INVESTIGATE THESE CLAIMS SO THAT THE PROBLEM CAN BE SOLVED? IF I COULD AFFORD A NEW VEHICLE IT WOULD SOLVE MY PROBLEM AND PASS IT TO SOMEONE ELSE, BUT I DON'T HAVE THE MONEY TO DO THAT. PLEASE HELP, THANK YOU.

AUG 2010 -- DRIVING ON INTERSTATE IN EXTREMELY HEAVY TRAFFIC AND ENGINE STALLED, LOSING POWER STEERING, BRAKES, AND GAS ACCELERATION . LIMPED TO EXIT, BARELY AVOIDING BEING REAR-ENDED BY 18-WHEELER AND BARELY GOT OFF FREEWAY BEFORE ENGINE DIED. HAD TO WAIT APPRX 1 HOUR BEFORE ENGINE WOULD START AGAIN. DROVE VERY SLOW AND CAUTIOUSLY NEXT 400 MILES HOME WITH NO FURTHER PROBLEM. JULY 2011 -- DRIVING IN CITY, TURNED CORNER AND ENGINE STALLED EXACTLY AS IN 2010 INCIDENT DESCRIBED ABOVE. WAS ABLE TO PULL INTO A PARKING LOT BEFORE BEING REAR-ENDED BY ANOTHER VEHICLE. ONLY HAD TO WAIT APPRX 15 MINUTES FOR ENGINE TO START AGAIN THIS TIME. MADE IT REST OF WAY HOME WITHOUT FURTHER INCIDENT. FOR PAST 3 YEARS, ESP LIGHT COMES ON RANDOMLY WHILE DRIVING DOWN HIGHWAY AND WON'T GO OUT. SOMETIMES PULLING OVER, KILLING ENGINE, THEN RESTARTING MAKES THE LIGHT GO OUT, AND SOMETIMES IT DOESN'T.

MY 2005 HYUNDAI TUCSON (2.7L V-6 4WD) HAS FOR THE LAST 1.5 YEARS HAS BEEN: 1.STALLING OUT 2. RUNNING VERY ROUGH WITH NO POWER (ESPECIALLY WHEN RAINING OR AFTER SEVERAL DAYS OF RAIN) 3. CRANKS OVER BUT DOESN'T START 4. ENGINE QUITS RUNNING ON HIGHWAY (LEAVING US STRANDED ON ROUTE I-80). ALL INTERMITTENTLY! I HAVE HAD THE CAR IN A REPAIR SHOP WHERE THEY REPLACED THE IGNITION COIL PACK ASSEMBLY (6/2011). THEN IT FAILED AGAIN BUT NOT LONG ENOUGH TO GET SOMETHING DIAGNOSED, SO I DROVE IT JUST KNOWING SOMEDAY IT WAS GOING TO HAPPEN AGAIN. FINALLY IT FAILED AGAIN (1/1/2012) THIS TIME LONG ENOUGH FOR ME TO GET THE CODE/S FROM THE ECM. IT HAD A HARD CRANKSHAFT POSITION SENSOR FAILURE. THEN IT RAN FINE. I REPLACED THE CRANKSHAFT POSITION SENSOR AND UPON REMOVAL AND INSPECTION THE SENSORS THREE WIRES WERE BARE. THE OUTER INSULATION COVERING ALL THREE WIRES WAS NOT ONLY GONE BUT THE INDIVIDUAL WIRE INSULATION WAS ALSO MISSING (ABOUT 3" OF BARE COPPER WIRE). A QUICK LOOK OF SOME WEBSITES TURNED UP PHOTOS OF FOUR OTHER CRANKSHAFT POSITION SENSORS THAT LOOKED THE SAME (MISSING INSULATION/ WIRES SHORTING) ALL COMING FROM HYUNDAI TUCSON'S. IN MY OPINION THIS IS A VERY VERY DANGEROUS SITUATION. LOOKING AT OTHER NTSB COMPLAINTS FOR 05, 06 TUCSON'S TURNS UP NEARLY 60 OTHER STALLING ENGINE; RUNNING ROUGH; ENGINE CUTS OFF; TYPE COMPLAINTS.

UNEXPECTED ACCELERATION OF ENGINE WHEN AT COMPLETE STOP (AT STOP SIGN) AND FOOT HAD BEEN ON BRAKE FOR AT LEAST 30 SECONDS. SHIFT WAS IN DRIVE, ENGINE WENT FULL SPEED, ALL WHEELS SPUN ON GROUND, CREATING MUCH SMOKE. FOOT REMAINED ON BRAKE. NOTE THAT ACCELERATOR PEDAL WHEN NOT ENGAGED IS BELOW LEVEL OF BRAKE PEDAL WHEN IT IS ENGAGED AND THAT WHEN ACCELERATOR PEDAL IS FULL DOWN THEN ITS LEVEL IS 3 INCHES BELOW THE BRAKE PEDAL LEVEL WHEN IT IS ENGAGED. RIGHT FOOT WAS ON BRAKE - THUS NO WAY FOR OPERATOR ERROR SINCE IF FOOT HAD BEEN OFF BRAKE THE VEHICLE WOULD HAVE SHOT FORWARD INTO INTERSECTION AND THERE WOULD HAVE BEEN A MULTIPLE CAR ACCIDENT. AND THERE IS NO WAY TO HAVE RIGHT FOOT ON BRAKE AND TO HAVE ACCELERATOR FULL DOWN AT THE SAME TIME. SHIFTED TO NEUTRAL, ENGINE CONTINUED TO RACE, SOME NOISE WHEN SHIFTED - MAY HAVE HARMED TRANSMISSION. TURNED OFF IGNITION SWITCH AND ENGINE STOPPED. VEHICLE STARTED NORMALLY AFTER THIS. AC WAS ON. CAR HAD FULL DEALER SERVICE AT 45,661 MILES AND STATE INSPECTION A WEEK BEFORE THIS INCIDENT. AT 45755 MILES, TECH CONFIRMED SES LIGHT; FOUND CODE P0150 OXYGEN SENSOR- NOT REPLACED, SOFTWARE UPDATED FOR ENGINE CONTROL MODULE. UPDATED 06/24/11

I HAVE A 2005 HYUNDI TUCSON 2.7L V6. IM HAVING PROBLEMS WITH THE VEHICLE STALLING WHEN COMING TO A STOP. THE PROBLEM HAPPENED TODAY AT A STOP SIGN. THANKFULLY THERE WASN'T ANOTHER CAR IN FRONT OF ME BECAUSE I COULDN'T STOP IN TIME FOR THE SIGN AFTER IT STALLED. THIS HAS NOT BEEN THE FIRST TIME THIS HAS HAPPENED. ITS HAPPENED ABOUT 6 OTHER TIMES, ALL WHEN COMING TO A STOP AT TRAFFIC LIGHTS, STOP SIGNS AND YIELD SIGNS. THE CAR DOES START RIGHT AFTER ITS STALLED. I'VE DONE A FAIR AMOUNT OF RESEARCH ON THIS ISSUE AND IT SEEMS IT HASN'T BEEN SOLVED YET. I'VE READ OF OTHER TUCSONS BEING INVOLVED IN ACCIDENTS DUE TO THIS PROBLEM. SOME CASES HAVE BEEN WHEN TRAVELING AY HIGHWAY SPEED. THIS IS A SERIOUS PROBLEM THAT NEEDS TO BE RESOLVED.

BEGINNING AT APPROXIMATELY 20K MILES THE ENGINE STALLS FOR NO APPARENT REASON. USUALLY OCCURS FOR A FEW DAYS AFTER EXTENDED HIGHWAY DRIVING THEN IT IS LESS PREVALENT. STALLING OCCURS MOST OFTEN WHEN SLOWING TO A STOP BUT HAS HAPPENED ON THE FREEWAY AT SPEED. VEHICLE NOW HAS 85K MILES ON IT AND PROBLEM IS STILL OCCURRING. HAS BEEN TO DEALER SEVERAL TIMES BUT NO "CODES" ARE SET AND THEY CANNOT DUPLICATE PROBLEM (SOMETHING ABOUT MANUFACTURER WILL NOT "ALLOW" THEM TO PERFORM EXTENDED DRIVING TO DUPLICATE FAILURE CONDITIONS). ON A FEW OCCASIONS THE ENGINE HAS STALLED IN TRAFFIC SITUATIONS WHERE ACCIDENTS WERE NARROWLY AVOIDED. WE NO LONGER FEEL SAFE IN THIS VEHICLE AS IT IS JUST A MATTER OF TIME UNTIL A SERIOUS ACCIDENT WILL OCCUR DUE TO THIS STALLING.

INCORRECT OIL DIPSTICK INSTALLED ON 2005 HYUNDAI TUCSON GL, 2WD,2.0L,AUTO. OWNERS MANUAL CALLS FOR 4.23 QUARTS, THIS WILL RESULT IN AN OVERFILL OF ABOUT 1/2 INCH OVER THE FULL MARK.

DEALER IS AWARE OF PROBLEM AND HAS CALLED TECH LINE AND HAS GOTTEN GUIDANCE TO CONTINUE TO PUT 4.23 QUARTS IN AND LET THE DIPSTICK READ OVER FULL. NO FIX IS OFFERED. HYUNDER CONSUMER AFFAIRS HAS BEEN NOTIFIED, CASE#3249498 AND HAS PROVIDED NO RESOLUTION.
