Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car would not accelerate as expected. It behaved as if the fuel injector was not working properly. We were not able to keep a consistent speed and the motor started to have a rough idle sound. The hybrid system stopped working, the icon of the batteries turned purple and would not recharge when stopping. We took it into the dealership, the service person they said it was a software and emissions miss-fire issue. It will take a part to be replaced and software updated. Toyota sent out a memo to them stating this might happen and this is how to fix it. …”
NHTSA complaint #11234238, filed 2019-07, 150,000 miles“Halfway through parallel parking, right rear of car by curb, foot lightly on brake, was about to shift to d and was looking around for any pedestrians short-cutting in front of car before shifting, when car accelerated, not stopping in spite of brake, until smashing into tree. (I was thrown around but no one else was hurt, luckily)”
NHTSA complaint #10883149, filed 2016-07, 7,000 miles“Was driving at approx 20mph on a side road when the car completely lost power and went dead. All the dashboard warning lights lit up at the same time. Lost steering control (the steering wheel became very heavy and was unable to steer). Managed to coast to a stop a 100 feet away (since the car had absolutely no power). Turned off the power button, turned it back on and the car started running again. Took it to the dealer the next day. They ran diagnostics, found codes (listed below) which suggested that the smart key lost communication with the car. …”
NHTSA complaint #10777968, filed 2015-09, 7,000 miles“Toyota issued safety recalls e0e and f0r for the failure of the hybrid inverter. If the inverter had not failed yet, the Toyota's remedy is a 'software re-flash'. The software reflash 'remedy' is not sufficient. There have been an excessive number of inverter failures after the software re-flash 'remedy' for these recalls has been completed. This is very dangerous to drivers, as it leads to unintended deceleration ' the prius spontaneously entering 'limp-home mode' or even a 'hybrid system shut down'. This is dangerous as in results in drastic reductions, if not the complete loss, of power. …”
NHTSA complaint #11054604, filed 2017-12, 31,222 miles“8/2025 Car stalled on freeway. Went to dealer. They said nothing wrong. Then on a trip north, car stalled again on freeway. Went to the nearest dealer. They too said nothing wrong. This time same thing. There is a recall for the exact symptoms of the exact car yet they say the repair was done. Why does my vin not qualify for the exact symptoms that generated a recall? This was super dangerous at freeway speed. Toyota knows there is a problem with the inverter and it's computer. Now I'm paying again for a diagnosis. …”
