Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #11265675, filed 2019-10, 111,000 miles“While driving in interstate traffic the car lost power and would only go 11mph. When I got to a safe place to pull over the hybrid system showed failure and several other warning lights. The car had a previous recall for power management completed in 4/2019. This is an invertor failure”
NHTSA complaint #11366871, filed 2020-10, 89,000 miles“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.”
NHTSA complaint #10947964, filed 2017-01“The hybrid system was shut down while driving. The symptoms are like the description in this recall (NHTSA Campaign Number: 18V684000). However, my VIN is not on the recall list.”
