“Automatically disengage the transmission Stopped the road Icalled my husband Myhusband came and together we got the car to a safe place.Then Icame home with my husband and he called the insurance company and had the car towed. Ifound a place to fix the car and they said the transmission was broken and it cost about 6500 dollars.Icontacted the insurance company said they couldn’t help.The car was towed home and is not available.”

“2003 TOYOTA HIGHLANDER 4 CYL. SERVICE BULLITON FROM THEM #310436. HEAD BOLTS COMING UNDONE INSIDE MOTOR CAUSING CATASTROPHIC FAILURE OF MOTOR. BOLTS NOT HOLDING DOWN MFGR KNOWS ABOUT THIS. WAS A MANUFACTURING PROCESS THAT DID NOT WORK. ON CARCOMPLAINTS.COM THIS IS A RAMPANT PROBLEM REPORTED. READS ALMOST LIKE A PLAY BOOK ON HOW THE MOTOR OVERHEATS AND FAILS, TOLD HEADGASKET, AFTER OPENING UP THE MOTOR IT IS FOUND THAT THE HEAD BOLTS BACKED OUT. TOYOTA IS NORMALLY A GREAT CAR. I STILL OWE MONEY ON THIS CAR AND TOYOTA IS BASICALLY NOT TAKING CARE OF THEIR CUSTOMERS AND LEAVING US OUT TO DRY. PLEASE ISSUE A RECALL ON THIS. VEHICLE WAS DRIVING AND QUICKLY OVERHEATED. THIS HAPPENED TWICE IN A SHORT DISTANCE. EASILY CAN LEAVE ONE STRANDED. NO STEAM OUT THE TAILPIPE AND WATER GUSHED OUT SIDE OF MOTOR. DEALER LEFT MOTOR APART WHEN I WENT TO PICK IT UP AFTER BEING DRAGGED ABOUT. THEY PROMISED TO FIX IT AT FIRST AS THEY DUG INTO THE MOTOR THEY BACKED OUT OF THEIR WORD.”

“HEAD BOLTS STRIPPED IN ENGINE , 66K MILES - COOLANT LOSS - ALL MECHANICS PREFER TO SWAP ENGINE - TOYOTA SERVICE SHOP BY ME QUOTED ME 5,000 FOR AN ENGINE AND 1 YEAR WARRANTY. THE CAR IS WORTH 8,000 TOPS. HEARTBROKEN BY THIS - WILL HAVE TO FIND A WAY TO MAKE REPAIRS ON MY OWN AND HOPE TO DRIVE AGAIN.”

“I HAVE BEEN THE OWNER OF MY 2003 TOYOTA HIGHLANDER, FOR ALMOST 8 YEARS. I GOT IT IN NOV.2008 AT AROUND THE 69,000 MARK. SINCE THEN, I HAVE MADE SURE THAT MY CAR/BABY HAS HAD THE WORKS IN CARE, TO KEEP THE QUALITY AND VALUE OF THE VEHICLE UP. THIS WOULD INCLUDE:OIL CHANGES, NEW BRAKES, NEW TIRES, REPAIRS OF BELTS/FILTERS ETC, HOSES, TUNE UPS, GREAT GAS AND CAR WASHES/BODY CARE. MOST OF THIS HAS BEEN DONE BY THE DEALERSHIP HERE IN CULVER CITY CA. I'VE DEPENDED ON THEM TO TELL ME WHAT WAS GOOD/BAD ABOUT MY CAR AND TRUSTED THEM IN DOING SO. I ALSO MADE SURE TO DO THE REPAIRS THEY SUGGESTED. SOMETIMES HOWEVER THEY SAID IT WAS FINE, BUT WOULD COME TO FIND OUT, I DID HAVE ISSUES. THIS MADE ME WONDER IF TOYOTA WAS TRUSTWORTHY/DOING THEIR JOBS RIGHT AND NOW I FEEL THE SAME LACK OF TRUST IN MY CARS PERFORMANCE /CURRENT STATE. I CAN SAY I HAVE ONLY PUT 50,000 MILES OR SO ON MY CAR IN THE LAST 8 YEARS, AND I KNOW TOYOTAS CAN/SHOULD LAST UNTIL 250,000 OR SO, WITHOUT MAJOR ISSUES. HOWEVER SINCE 2015 I HAVE DEALT, WITH ONE THING AFTER THE NEXT WITH THE CAR. MOST RECENTLY THIS PAST WEEKEND WHERE MY ENGINE COMPLETELY BLEW. HOW COULD A ENGINE BLOW OUT ON SUCH A WELL MAINTAINED…”

“THE ENGINE OVERHEATED SUDDENLY, BLOWING HOT AIR FROM THE AC AND THE TEMPERATURE GAUGE WENT UP. WE MANAGED TO GET HOME AND GET TO THE TOYOTA DEALERSHIP THE NEXT DAY. THE DEALERSHIP MECHANIC TOLD US THE ENGINE BOLTS STRIPPED DUE TO THE BLOCK BEING SOFT, AND THAT HE HAD SEEN THIS PROBLEM BEFORE. THE ISSUE OF THE SOFT BLOCK WAS CONFIRMED IN A SUBSEQUENT SEARCH OF THE INTERNET. APPARENTLY TOYOTA IS AWARE OF THIS FLAW, BUT THERE IS NO WARRANTY REMEDY. THE 2003 INLINE 4-CYLINDER ENGINE IS THE MODEL WITH THE BOLT STRIPPING PROBLEM. NEITHER THE DEALERSHIP NOR ANOTHER JAPANESE AUTO REPAIR PLACE WOULD CONSIDER TRYING TO REPLACE THE BOLTS. THEY SAID THAT BECAUSE OF THE SOFT METAL IN THE BLOCK, A NEW SET OF LARGER BORED BOLTS WOULD BE UNLIKELY TO HOLD. THE COST TO PUT IN ANOTHER ENGINE IS APPROXIMATELY THE VALUE OF THE CAR, IF THERE WERE USED ENGINES AVAILABLE. A NEW ENGINE WOULD BE IN THE $15K RANGE, MUCH MORE THAN THE CAR IS WORTH. WE WILL LIKELY SELL THE CAR FOR SCRAP. WHEN WE BOUGHT THE CAR, WE FELT WE COULD REASONABLY EXPECT A 250K MILEAGE LIFE. THE ENGINE FAILED AT 128K. JUST HALF OF ITS USEFUL LIFE.”

“NEEDED TO HAVE A TOTAL ENGINE REBUILD DUE TO FAULTY HEAD BOLTS THAT STRIPPED AND ALLOWED COOLANT TO ENTER THE ENGINE AND BURN. LUCKY-I GUESS-THAT I ACTED QUICKLY SO AS TO AVERT CATALYTIC CONVERTER ISSUES OR SENSORS GETTING DAMAGED BY BURNING COOLANT. I ALSO AVOIDED THE TOTAL LOSS OF ANTIFREEZE AND THE RESULTING DAMAGE &/OR INCONVENIENCE THAT THOUSANDS OF OTHERS HAD. STILL, A HUGE INCONVENIENCE AND HUGE $5425.82 COST DUE TO MANUFACTURER'S DEFECT: WEAK METAL THAT COULDN'T WITHSTAND THE TORQUE/PULL ON THEM... PERHAPS THE THREADING PLAYED A PART. I ONLY KNOW THAT 1000S UPON 1000S OF PEOPLE SUFFERED THE SAME ISSUE FROM TOYOTA ON THIS ENGINE IN SEVERAL YEARS/MODELS. THERE SHOULD BE A RECALL. THERE SHOULD BE COMPENSATION. *TR”
