Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

THIS IS A VERY DANGEROUS ISSUE. CAR ENGINE RANDOMLY SHUTS OFF WHILE DRIVING. CHECK ENGINE LIGHT WILL NOT GO OFF. I CANNOT DRIVE CAR BECAUSE I CANT PASS SMOG EITHER (DUE TO CHECK ENGINE LIGHT). I HAVE FILED TWO FORMAL COMPLAINTS WITH TOYOTA. TOYOTA REFUSES TO TAKE RESPONSIBILITY FOR THE MANUFACTURING. DEFECT. I AM EXPECTED TO PAY OVER $2000 TO REPLACE A CATALYTIC CONVERTER THAT THEY KNOW IS DEFECTIVE. (EXCERPT FROM ONE COMPLAINT I FILED) THERE WAS A RECALL ON MATRIX AND COROLLA: TOYOTA ISSUED A RECALL FOR 2005 TO 2008 MODEL YEAR COROLLA'S AND MATRIXES, EQUIPPED WITH THE 1ZZ-FE ENGINE AND TWO-WHEEL DRIVE. THE RECALL NOTICES STATES THAT AN IMPROPERLY MANUFACTURED ENGINE CONTROL MODULE (ECM) CAN DEVELOP A CRACK IN ITS CIRCUITRY, POTENTIALLY CAUSING THE "CHECK ENGINE" LIGHT TO ILLUMINATE, HARSH SHIFTING, AND STALLING AND/OR FAILURE OF THE ENGINE TO START. I HAVE A 2003 MATRIX XRS WITH A 2ZZ-GE ENGINE WITH A CONTINUOUS CHECK ENGINE LIGHT, HARSH SHIFTING, STALLING AND RANDOM FAILURE OF THE ENGINE TO START. I HAVE HAD MULTIPLE DIAGNOSTICS AND REPAIRS DONE ON THE VEHICLE TO PASS SMOG INSPECTION OVER THE PAST 5 OR 6 YEAR AND HAVE SPENT THOUSANDS OF DOLLARS. THE LIGHT STAYS OFF JUST LONG ENOUGH TO PASS THE SMOG TEST AND IS THEN RETURNED TO ME WITH THE LIGHT STILL ON. I HAVE PAID A TOYOTA DEALER $95 TO RUN DIAGNOSTIC ALSO. THEY SAID THE ECM IS CORRUPT AND CAN'T BE FLASHED AND THE CAT HAS TO BE REPLACED FOR OVER 2K! I WOULD LIKE INFORMATION FROM YOU'RE QUALITY DEPARTMENT AS TO WHY TOYOTA WILL NOT REPLACE THE ECM BEING REPLACED ON THE ENGINES STATED IN YOUR RECALL NOTICE AND NOT ON MY TYPE OF ENGINE. WHICH HAS THE EXACT SAME PROBLEM AS DETAILED IN THE RECALL LISTED ON YOUR SITE. TOYOTA STATED AFTER BOTH COMPLAINTS THAT THEY CANNOT HELP ME OR FIX THE PROBLEM. I MUST PAY FOR SOLUTION MYSELF. DOES SOMEONE NEED TO DIE IN A CRASH BEFORE THIS IS ADDRESSED? *JB

IT'S BEEN ALMOST A YEAR SINCE THE FIRST TIME THE CIL TURNED ON. IT STAYS ON FOR A COUPLE DAYS THEN STAYS OFF FOR LIKE A MONTH. IT HAS BEEN DOING THAT SINCE 2012. I HAD MY CHECK ENGINE LIGHT CHECKED BY A TECH AND HE SAID THAT HE HAS SEEN THE P0770 CODE MANY TIMES FOR THE MATRIX AND COROLLA. HE PRINTED OUT THE TSB (HTTP://WWW.MATRIXOWNERS.COM/TSB/T-EG020-02.PDF) AND ADVISED ME TO TAKE IT TO A TOYOTA SERVICE CENTER. I TOOK IT TO CARSON TOYOTA IN CA AND THEY PRETTY MUCH SAID THE ONLY THING I CAN DO IS FIX THE ISSUE OUT OF MY POCKET WHICH WAS ALMOST $1500! HE SAID THE ISSUE IS THE R & R ENGINE CONTROL MODULE AND IF THAT DOESN'T DO THE TRICK THAT I HAVE TO REPLACE R & R SPEED SENSOR. I PURCHASED MY CAR USED SO IT DIDN'T QUALIFY FOR THE MANUFACTURES WARRANTY. I PERSONALLY THINK THAT THIS SHOULD QUALIFY AS A RECALL. THERE IS SO MANY REPORT ABOUT THIS ISSUE AND SO MANY OTHER TOYOTA CUSTOMERS THAT ARE VERY UNHAPPY. ALLOT OF THE CONSUMERS ARE SAYING THEY HAVE BOUGHT THESE PARTS AND INSTALLED THEM AND THE CIL IS STILL LIGHTING UP. I WOULD REALLY LIKE TO RESOLVE THIS ISSUE. I REFUSE TO PAY $1500 TO REPLACE THE ECM AND THE SPEED SENSOR FOR IT TO NOT FIX THE PROBLEM. NOW I HAVE TO HAVE MY CAR REGISTERED WITH THE REQUIREMENT OF A SMOG CHECK. AND OF COURSE THAT IS AN AUTOMATIC FAIL. THIS IS MY SECOND TOYOTA AND I DON'T THINK THERE WILL BE A THIRD. VERY UNHAPPY CUSTOMER! *TR

THREE INCIDENTS - 2ND OCCURRED IN MAY 2014, 3RD IN AUGUST 2014. VERY LARGE, CLEAN CRACKS KEEP APPEARING IN THE SAME SPOTS ON THE FRONT WINDSHIELD WITH NO POINT OF CONTACT. THEY BEGIN FROM THE MIDDLE BOTTOM OF THE WINDSHIELD WHERE THE HEAT VENTS START AND IN A U-SHAPE COME OUT OR AT THE TOP MIDDLE - BEHIND REAR VIEW MIRROR - WHERE HEAT VENTS START - LIKE A SMILEY FACE TO NEARLY THE TOP OF THE WINDSHIELD OR A LINE DOWN DIRECT FROM MIDDLE OF WINDOW. THE FIRST TIME IT HAPPENED I WAS USING THE HEATER . THE SECOND TIME AND 3RD TIME IT WAS PARKED OVERNIGHT BUT NOTHING WAS STOLEN, NO OTHER DAMAGE AND NOTHING TO INDICATE A POINT OF CONTACT SUCH AS A ROCK OR SHARP TOOL. FULL CRACKS APPEAR ALL AT ONCE - CLOSE TO ENTIRE HEIGHT OF WINDOW AND ARE NOT GRADUAL. REPLACED THE WINDSHIELD FIRST TIME AT MY COST AND NEED ANOTHER REPLACEMENT IMMEDIATELY AS TWO LARGE CRACKS ARE IMPAIRING VISIBILITY, TAKE UP THE WHOLE DRIVERS SIDE OF THE WINDOW AND CONCERNED FOR SAFETY WITH UPCOMING ROAD TRIP. LOOKING FOR ANOTHER VEHICLE TO BUY AS ALREADY HAD 2 OTHER RECALLS WITH THIS VEHICLE. NEED TOYOTA TO REPLACE 2ND WINDSHIELD AS THIS IS CLEARLY A MANUFACTURERS PROBLEM. *TR
