Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Sometimes as I drive the vehicle, after a while, either one of the headlights turns off randomly. I don't always notice when it happens, other than when pulling up behind another vehicle at a stop light and notice that there is only 1 headlight reflection coming from my vehicle. They both work normally if I turn them off and on again.”
NHTSA complaint #11099340, filed 2018-06, 80,000 miles“Combination meter is going out on the car. This controls the dashboard lights, meaning that I cannot see how fast I am going or if there are any gauges or sensors lit up alerting me to a problem with the vehicle. Toyota had an extended warranty on this but it has now expired and they want $1000 to fix it.”
NHTSA complaint #11073261, filed 2018-02, 138,000 miles“My hv battery has a problem. The red triangle showed when the car millage was only 118000m. I checked with servco and replaced one cell of the hv battery. However, the red triangle showed again, and code reader found another damaged cell. That would be a possibility that the whole hv battery was damaged.”
NHTSA complaint #11156707, filed 2018-12, 118,000 miles“My 2006 Toyota Prius headlight goes off when driving. It flickers first and then goes off. Sometimes one light goes off and sometimes both of them. When I turn the light off and turn it back on headlights work again. But after a while they turn off again. They stay on steady after I drive for more than an hour in long trips and after turning it off and then on again several times.”
NHTSA complaint #10676509, filed 2015-01, 93,000 miles“Known problem with combination meter - found it searching online once I realized this was the problem. I bought my car used and since it is no longer covered by Toyota, it didn't come up in search. Having issues with there being no display on the dash and vehicle not shutting off for the entire time I have had the car. It only happens intermittently. This is a safety issue for sure! Can't see speed, gas, gears...anything about car whether car stationary or moving.”
