On june 5th, 2019, i took my car in to round rock toyota and they performed the 2018 toyota prius v recall fix. since then, my mpg has gone from an average of 41 miles per gallon, which has stayed consistent since i purchased the car brand new in june 2012, down to 32 mpg. i took the car back to round rock toyota for a diagnosis on sept 30, 2019 and they said that they cannot find anything wrong, there are no error codes, and that my now greatly reduced 32 mpg fell within toyota standards. i am writing to file a complaint that their 2018 recall for the toyota prius v has a problem and needs to be revisited or the vehicles should be taken off the road. i am co-filing a complaint with the epa as well.
Took in car for oil change /tire rotation , a software update was performed without my authorization from toyota on to my prius v , car went from getting 40 mpg highway to 32-33 mpg highway . city mpg dropped from 41 mpg to 36-37mpg . dealer claims car has wrong tires which i agree, except those tires were the same tires on the car before and after the software update. calculated the gas mileage myself before the recall and was pretty close to what the car's computer said ti was , calculated the gas mileage after the software update was done and it came very close to what the computer said.
