| May 2020 | SUSPENSION | THE VEHICLE HAS BEEN WEARING TIRES DOWN UNEVENLY TO THE POINT STEEL BRAID BECOMES EXPOSED. IT HAS HAD 3 SETS OF TIRES IN LESS THAN 2 YEARS. IT HAS BEEN ALIGNED TWICE. THE REAR WHEELS ARE NOT WITHIN SPECS AND ARE FIXED AND IN ADJUSTABLE. TOYOTA HAS REFUSED TO LOOK INTO THE PROBLEM ANY FURTHER AND HAS STATED THAT IT MIGHT BE HOW THE VAN RIDES. HAVING THE ALIGNMENT OFF CAUSES THE TIRES TO WEAR DOWN TO AN UNSAFE LEVEL AND IT AFFECTS VEHICLE HANDLING AND PERFORMANCE. *TR | Crash: No Fire: No | 55,000 |
| May 2020 | UNKNOWN OR OTHER | I AM UNABLE TO PAY MY RENEWAL REGISTRATION FEE BECAUSE THERE IS NO AVAILABLE REMEDY FOR THE RECALL ON MY VEHICLE YET. I AM NOT SURE WHAT TO DO AT THE MOMENT. THE DMV TOLD ME TO CONTACT MY DEALER. BUT MY DEALER RESPONDED BY STATING THAT THERE IS NO REMEDY TO FIX THE VEHICLE YET. THE DEALER SAID THAT I SHOULD NOTIFY THE DMV SO THAT THEY COULD INVESTIGATE FURTHER AND ALLOW ME TO PAY MY DUES. THIS CURRENT COVID-19 PANDEMIC HAS MADE IT DIFFICULT FOR ME TO GET IN CONTACT WITH THE DMV. *TR | Crash: No Fire: No | 10,000 |
| May 2020 | UNKNOWN OR OTHER | MY VAN HAS BEEN SITTING IN THE DRIVEWAY DURING THE COVID-19 LOCKDOWN. ONE DAY I NOTICED A CRACK FROM TOP TO BOTTOM DOWN THE MIDDLE OF THE WINDSHIELD. THIS HAS TO BE DUE TO A MANUFACTURING DEFECT BECAUSE THERE WAS NO ACCIDENT, NO TREES ABOVE THE VAN, AND THE PATTERN IS NOT THE SAME AS WINDSHIELDS THAT HAVE BEEN HIT BY ROCKS. THIS MODEL VAN HAS HAD MULTIPLE SAFETY RECALLS AND A CLASS ACTION LAWSUIT SO I WON'T BE SURPRISED IF THIS WAS A MANUFACTURING DEFECT. MY HOPE IS THAT THIS WILL TURN INTO A SAFETY RECALL AND TOYOTA TAKES RESPONSIBILITY AND FIXES IT. THE "BUMPER TO BUMPER" WARRANTY DOES NOT COVER WINDSHIELD DEFECT. THEY DEALERSHIP CLAIM THAT IT WAS CAUSED BY WEAR & TEAR WITHOUT EVEN INSPECTING IT. WHEN I CALLED CORPORATE, THEY SAID THE SAME THING AND I CAN TAKE IT INTO THE DEALERSHIP FOR AN INSPECTION. HOWEVER, I WOULD HAVE TO PAY FOR THE INSPECTION FEE. *TR | Crash: No Fire: No | 8,020 |
