Yokohama avid envigor 215/50/r17 tread separation: rear driver side tire developed a crack on the inside of the tire. tires have 18,000 miles on them. installed 12/27/2017. crack resulted in air loss triggering the tpms system. discovered while driving on city street. removed wheel and inspected vigorously before finding said crack. contacted yokohama and gave them opportunity to take responsibility for the defect, sent them picture of crack but they refused to do anything about it, claiming it's a road hazard damage. when a tire cracks, this indicates weak tread and delamination of the tire layers (tread separation). spent a week communicating with them (yokohama) to no avail. they adamantly refused to take responsibility.
Tread tire separation on all four oem toyo tires. required tire replacement.
Since the vehicle was purchased, the odometer has been off by about 2 miles per hour at 65, and 3-4 miles per hour at 95. this means that the oboe get is recording 4% higher mileage than what is actually being driven. my car is not alone, many prius v models have the same problem. dealership did not have a solution. this not only voided my 100,000 mile warranty 3-4k miles early, but it makes the fuel economy look better on paper than it actually is- a selling point that toyota takes advantage of. to me, this is just as bad as what volkswagen did with their diesel vehicles.
