2018 TOYOTA MATRIX IM THIS IS A LETTER ADDRESSING THE VEHICLES THAT ARE BEING SOLD AND DISTRIBUTED IN MY STATE OF CALIFORNIA. AS AN AMERICAN TO THIS BEAUTIFUL NATION, UNITED STATES OF AMERICA, I'M APPALLED TO FIND THAT TOYOTA MOTOR SALES, U.S.A. IS LOSING BUSINESS AND HAVING COPYCATS OR AS I MAY CALL THEM TOYS 'SOLD' ON BEHALF OF A RELIABLE AND REPUTABLE COMPANY. AS A CHILD I NEVER PLAYED WITH TOYS AND HAVE ALWAYS HAD MY EYES IN BOOKS AND ON THE PRIZE. AS A MAN I KNOW I DON'T DESERVE A CAR THAT IS A HOT WHEEL PROTOTYPE.

THE VEHICLE CAME WITH UPGRADED PARTS THAT WERE INSTALLED BY THE DEALERSHIP. I DO NOT FEEL COMFORTABLE OR SAFE IN THIS VEHICLE. AN UNUSUAL SMELL COMING FROM THE ENGINE HAS BEEN LINGERING FROM DAY ONE OF THE PURCHASE. I DISREGARDED THE SMELL FOR A FEW WEEKS AND ADDRESSED MY CONCERN TO THE SERVICE DEPARTMENT AFTER THE VEHICLE HAS BEEN GIVING ME EXTREME HEADACHES. THE SERVICE DEPARTMENT ADVISED THE CVT TRANSMISSION IS CONFORMED TO OPERATE WITH A SMELL THAT WILL LAST FOR SEVERAL MONTHS AND EVENTUALLY DISAPPEAR. TO MY DISCOVERY I FOUND THAT THERE ARE STYROFOAM PIECES THAT ARE PLACED UNDER THE FLOOR MAT, ONE DISTINCTIVELY UNDER THE BRAKE PEDAL AREA WHICH IS A SERIOUS SAFETY CONCERN FOR CONSUMERS. FROM PERSONAL USE I KNOW THAT STYRFOAM IS MAINLY USED TO KEEP LIQUIDS THAT ARE EITHER HOT OR COLD AT THE DESIRED TEMPERATURE.

Originally my rear left tire had a blow out on 6/28, and when I brought the car in to have the tire changed on 6/29, Goodyear determined that the belts on all 4 tires were defective and concluded that it was a manufacturers defect. 1. Defective tires were replaced and recycled by Goodyear. 2. Safety at risk and could have led to another blowout or worse. unable to reproduce the issue. 3. Vehicle inspected by Toyota initially for the annual inspection, but unless the tires were removed they would not be able to see the bands. 4. The only time the tire pressure light came on prior to this was when I had a puncture that was repaired by Toyota. Since then there have been no other warnings. 225/45Z R17 94W DOT NUMBERS: CMH8AKM2123 CMH8AKM2223 CMH8AKM2223 CMH8AKM3023
