Engine, Jun 25, 2021
Engine seized, yes available for inspection, no prior warning lamps, messages or symptoms, car just stopped. Fortunately this happened on a backroad and not on interstate 95 between home and school. Manufacture said they would not help, seized engine determined by mechanic, no oil. Car maintained as recommended by manufacturer. I'm now finding out this is a common problem with this make and model, it burns oil and engines seize. Who allows cars to be on the road that seize up!!!

Opened hood and engine was on fire and wouldnt stop. Bystanders tried helping but fire couldnt be contained and the entire Tucson engulfed in flames. Hyundai claimed no recalls for that model and couldnt help in any way. Vehicle was completly factory with 0 aftermarket modifications. 2015 Hyundai Tucson.

The vehicle suddenly reduced power on 05/27/2021 while my 82-year old mother was driving home. When I checked the car, the check engine light was blinking. I Immediately took to a service center and noticed the same low power 'limping' performance and a knocking sound (previously unheard). On Friday, 05/28/2021, the service manager provided an update: that they found Diagnostic trouble code p1326 related to engine inspection. Performed oil change. Cleared the diagnostic code. Ran the engine. Could hear an internal knock at higher RPMs. Will need engine replaced or rebuilt. No parts are available to replace or rebuild at this time. They contacted Hyundai with the VIN who said the vehicle was out of warranty (110,000 miles). Drove the vehicle home (two blocks) at low RPMs with no issue. There was no previous indication there was any potential issue with the engine. Maintenance and oil changes have been completed on a regular basis. There were 600+ miles before the next 5,000-mile oil change was due. Drove the car the next morning, Saturday, 05/29/2021, to see about trading the car in at the local Hyundai dealer (5.1 miles away) before the situation got worse and purchase a new vehicle. I was expecting the car would be drivable - at least at lower RPMs. The car immediately began to lose power, the check engine light began blinking and stalled three times in traffic before crawling onto the dealer's lot. They had a mechanic look at the vehicle, said the engine was shot and offered $250 as all they could do was junk it since engine parts were scarce and it would not be cost-effective to replace the engine even though the body was in good shape. I felt I had no choice but to accept as it was now clear the vehicle was unsafe to drive. For the engine to die within about 15 miles of the initial onset without warning and the sudden loss of power, is a dangerous situation is this is waiting to happen to other vehicles.

I was driving down the road when suddenly the car started rattling. The oil light blinked on then off. The engine then made a squealing noise, the battery light came on, and then the engine froze. The accelerator pedal and the steering wheel were stuck. I turned the car off, but it wouldn’t restart. Thankfully, I was on a quiet neighborhood street and not in the middle of a busy highway when this happened. I had it towed to the dealer, who inspected it and stated that I needed to have the entire engine replaced. I then had it towed to another dealer for a second opinion, but they also said the engine needs to be replaced. Unfortunately, since I am not the original owner, Hyundai claims the 100,000 mile powertrain warranty does not apply, even though the car only has 85k miles.

CAR WAS DRIVING FINE, LOST ALL POWER TO A VERY SLOW CREEP, MAKING A VERY STRANGE SOUND IN ENGINE, FRIED STARTER AND NOW WON'T WORK AT ALL. EVERYTHING PEOPLE SAY THE THETA II ENGINE COMPLAINTS HAVE BEEN WE ARE EXPERIENCING WITH THIS CAR...BUT IT HAS NOT BEEN RECALLED. WE HAVE NOTICED EXTRA OIL CONSUMPTION BUT FIGURED DUE TO HIGH MILEAGE. WE HAD A MECHANIC COME OUT AND HE SAID THE THINKS THE ENGINE IS FRIED OR THERE IS SERIOUS PROBLEMS. THIS VEHICLE IS ONLY 6 YEARS OLD. THIS ALL DURING COVID, MY HUSBAND IS HIGH RISK WE HAD TO GO BUY ANOTHER CAR AS WE DO NOT HAVE MONEY TO FIX. I NOW HAVE 2 HEFTY CAR PAYMENTS WITH 1 VEHICLE WORKING. I NEED HELP TO KNOW IF THIS ENGINE DISPLAYING ALL THE SAME PROBLEMS WILL TOO BE RECALLED .

MY CAR IS CONSUMING OIL - APPROXIMATELY 1 QUART PER EVERY 300 - 500 MILES. A REPAIR SHOP SAID THERE WERE PROBLEMS WITH THE ENGINE AND TO TAKE IT TO THE DEALER. I HAVE PAID OVER $500 SO FAR (REPLACED GUAGES, SPARK PLUGS, AND MORE) - I HAVE COMPLETED THREE OIL CONSUMPTION REPORTS (THE DEALERSHIP IS CHECKING THE OIL)- AND THE DEALER KEEPS SAYING THE PROBLEM IS NOT COVERED UNDER WARRANTY. I KNOW SO LITTLE ABOUT CARS AND ENGINES, BUT FEEL I AM GETTING CHEATED. ANY SUGGESTIONS ARE APPRECIATED.

COMPLETE ENGINE FAILURE AT ONLY 47,000 MILES! WHILE DRIVING MY ENGINE LIGHT COMES ON AND I CAN TELL I WAS LOOSING POWER, I HEARD A "KNOCKING" SOUND SO I PULLED OVER AND ALL OF MY LIGHTS COME ON MY DASH AND THE CAR IS DEAD! SO GLAD I WASN'T ON THE HIGHWAY! I HAD IT TOWED AND THE MECHANIC AND HA HAS CONFIRMED THAT IT IS A COMPLETE ENGINE FAILURE - I NEED A NEW ENGINE. CALLED THE NEAREST HYUNDAI DEALERSHIP, AND THEY SAID I'M OUT OF WARRANTY (5 YEARS / 60,000 MILES). I WOULD HAVE BEEN COVERED IF THIS HAPPENED A MONTH EARLIER. LOOKS LIKE I GOT TO PUSH THIS UP HILL. I'LL NEVER BUY HYUNDAI AGAIN AND I SWEAR TO TELL THIS STORY TO THE END OF MY DAYS!

MY VEHICLE WAS STATIONARY IN MY GARAGE WHEN I STARTED TO LEAVE FOR WORK WHEN THE CAR BEGAN TO SHAKE, AND THE ENGINE TURNED OFF. I RESTARTED THE CAR, AND THE CHECK ENGINE LIGHT, WHICH WAS NOT PREVIOUSLY ON, NOW WAS, AND MY AIRBAG LIGHT INDICATOR WAS ON AS WELL. SINCE THIS TIME, MY SHIFTER CABLE HAS BROKEN, AND THE BRAKE LIGHT SWITCH HAS MALFUNCTIONED. TO TRY AND REMEDY THIS, I HAVE PURCHASED AND REPLACED MY IGNITION COILS, SPARK PLUGS, BRAKE LIGHTS, SHIFTER CABLE, CRANKSHAFT POSITION SENSOR, THE MASTER POWER WINDOW SWITCH, AND FUSE PLUGS. AND THIS STILL HAS NOT FIXED THE ISSUES OCCURRING WITH THE VEHICLE.

ON NOV. 4 2020 AT 2PM, WHILE DRIVING ON F8 EAST FREEWAY ENTERING THE TURN ONTO CA125, MY 2015 HYUNDAI TUCSON'S ENGINE BLEW WITHOUT WARNING. THE DASH LIGHTS LIT AS THE CAR LOST POWER THE HOOD BLEW OPEN AND SHUT AND MY 31YR OLD DAUGHTER WAS FORCED TO ALLOW THE CAR TO GLIDE TO THE SIDE OF THE FREEWAY. IN A DANGEROUS SPOT. .SHE COULD NOT SEE IN FRONT OF THE CAR UNTIL THE HOOD FELL BACK DOWN. THE DANGER IS THE FACT THERE WERE NO PREVIOUS WARNINGS, THE HOOD BLEW UP AND THE CAR HAD STOPPED WHERE THERE WAS NOT SUFFICIENT SPACE FOR OTHER CARS TO PASS WITHOUT TAPPING MY SIDE MIRROR AND A HUGE TRAIL OF OIL LEFT BEHIND. SHE GOT OVER TO THE PASSENGER SEAT QUICKLY AND ROLLED DOWN THE WINDOWS SINCE IT WAS HOT OUT. FIRST SHE CALLED EMERGENCY ROADSIDE ASSISTANCE TO TOW THE CAR OFF THE FREEWAY. THEY TOOK OVER 2 HRS TO ARRIVE .WHILE MANY CARS DROVE QUICKLY BY BARELY MISSING MY CAR. SHE CALLED ME NEXT IN FEAR OF HER LIFE AND THEN CALLED HER DAD AND HE STAYED ON THE PHONE WITH HER UNTIL THE TOW ARRIVED .I ONLY HAVE HAD THIS CAR FOR 1 YEAR. I HAD AN OIL CHANGE ON JUNE 23, 2020 FROM REG OIL TO A SYNTHETIC BLEND. UPON CALLING HYUNDAI CUSTOMER CARE IT WAS SUGGESTED TO TOW THE CAR TO THE NEAREST DEALER FOR INVESTIGATION TO SEE IF ITS COVERED BY WARRANTY. THE ENGINE IS SEVERELY DAMAGED THE BEARINGS WERE DESTROYED AND A ROD THROWN. THE OIL FILTER WAS BLOWN OFF. MY CAR HAD NO PREVIOUS LEAKS. THERE IS A CLASS ACTION AGAINST HYUNDAI/KIA FOR MY CARS YEAR BUT WITH THETA 1 AND !! ENGINES. MINE IS A GASOLINE DIRECT ENGINE THAT ALSO HAS PROBLEMS PER CAR COMPLAINTS.COM. WHAT ALSO MAKES THIS PARTICULARLY DANGEROUS IS THAT I USE THIS CAR FREQUENTLY TO TRANSPORT MY 11YR OLD DISABLED GRANDSON TO RADY CHILDREN'S HOSPITAL FOR MEDICAL APPTS SINCE HE HAS CEREBRAL PALSY AND POOR HEAD AND NECK CONTROL. SOMETHING LIKE THIS COULD HAVE NOT ONLY SNAPPED HIS NECK BUT ALSO CAUSE MASSIVE FATALITIES ON THE FREEWAY..

THERE WAS A RECALL ON MY CAR WHICH FOLLOWED UNDER THE CAMPAIGN 958 WHICH WAS UNKNOWN TO ME UNTIL MY CAR ENGINE SEIZED WHILE DRIVING ON I-5 HIGHWAY. DUE TO THE FACT I DID NOT KNOW OF THE RECALL WHEN THIS INCIDENT HAPPENED I HAD TO GET IT TOWED TO THE CLOSEST AUTO SHOP. THEY WERE UNSURE OF WHAT CAUSED THE SEIZE AND TRIED TO REPLACE THE STARTER (COST AROUND $340). THE AUTO SHOP GOT IT TO TURN ON BUT THEN HEARD A LOUD KNOCKING IN THE ENGINE AND SUGGESTED IF I CALLED HYUNDAI DEALERSHIP TO SEE IF THERE IS A RECALL BECAUSE THEY WOULD HAVE TO REPLACE THE ENGINE. I CALLED AND GOT THE CONFIRMATION THAT THERE WAS A RECALL AND GOT IT TOWED TO THEIR PARKING LOT(AROUND $98). I BELIEVE IT WAS A MONDAY WHEN IT MADE IT TO THE PARKING LOT AND SAID THE TECHS WOULD HAVE TO CHECK IT OUT AND SEND UP AN APPROVAL IF THE ENGINE IS COVERED AND TILL THE CONFIRMATION CAME THROUGH I WOULD HAVE TO GET A RENTAL OUT OF POCKET. SO FROM MONDAY TO THURSDAY I HAD TO GET A RENTAL THROUGH ENTERPRISE(AROUND $350) BECAUSE ON THURSDAY I RECEIVED A CALL FROM THE DEALERSHIP STATING THAT I WAS APPROVED AND COULD GET ONE OF THE DEALERSHIP RENTALS TILL THE REPAIRS WERE MADE WHICH RESULTED IN MY ENTIRE ENGINE BEING REPLACED. I HAD THEIR RENTAL I BELIEVE FROM FRIDAY TO THE NEXT THURSDAY AND THEN I WAS ABLE TO PICK MY CAR UP. AFTER ALL WAS SAID AND DONE I SUBMITTED TO THE REIMBURSEMENT BRANCH ALL THE EXPENSES I PAID WITH THE RECEIPTS THAT WAS EARLY JULY WHEN I GOT CONFIRMATION THAT IT WAS RECEIVED. SINCE THEN I HAVE REACHED OUT NUMEROUS TIMES TRYING TO GET AN UPDATE FOR HOW LONG IT WOULD TAKE AND IF I COULD SPEAK TO A SUPERVISOR OR EVEN HAVE THE PERSON WORKING ON MY CASE REMOVED TO SOMEBODY ELSE TO MAKE THINGS WORK FASTER. I WAS TOLD THEY DON'T HAVE SUPERVISORS AND THAT MY CLAIM IS WITH HIGHER MANAGEMENT FOR APPROVAL AND THAT IT HAS BEEN THERE SINCE THE 6TH OF AUGUST.

IN AROUND AUGUST 2018, I WAS DRIVING MY 2015 HYUNDAI TUCSON GLS BACK FROM WORK ON A HIGH WAY. THAT ALL (FOR NO REASON) THE INDICATOR ON THE DASHBOARD LIGHTS UP, THE VEHICLE SHAKES AND COME TO A HALT. I TOWED TO DEALERSHIP WHERE THE MAINTENANCE HAD BEEN DONE SINCE THE PURCHASE DATE. IT WAS CHECKED AND REPORTED AS A DAMAGE TO THE OIL PAN. BUT, THEY SAID IT HAS HIT A STATIONARY OBJECT (THIS WAS A LIE) BUT THERE WAS NO STATIONARY OBJECT ON THE HIGHWAY AS MANY VEHICLE WERE GOING BY. I WAS ON THE LEFT SHOULDER OF THE FAST LANE. BECAUSE I DID NOT AGREE WITH THE DEALERSHIP DIAGNOSE, I KNEW AN OBJECT HAS BROKEN FROM THE INSIDE OF THE ENGINE AND STRIKE IT WAY OUT OF THE OIL PAN. MILEAGE DURING THE INCIDENT WAS AT 73,437. I THINK THIS VEHICLE SHOULD BE RECALL FOR THIS MANY REPORTED OBJECT DAMAGING THE OIL PAN. MY INSURANCE HAD TO PAY FOR A NEW REPLACE ENGINE BUT TO END UP WITH A USED ENGINE CHARGE $4500. A PICTURE (DOCUMENT) UPLOADED WILL SHOW EXIT DAMAGE FROM THE BROKEN METAL FROM INSIDE THE ENGINE. *TR
