Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After receiving the computer update my fuel mileage has dropped 10 miles. The other problem in the rate of tire wear and pull. I took the car in for an alignment to a Toyota dealership because it was pulling they told me they did the alignment. After I got my car back it was still pulling I questioned them and they said that was normal. The last thing is I got new tires put on the car and had to replace them 10 months later because there was about 15 percent tread life left. The tires were rotated properly.”

NHTSA complaint #11156577, filed 2018-12, 115,000 miles“In motion while accelerating past a slower car. Heard and felt a pronounced thump and lost engine power on busy local thoroughfare. Moved to a turn lane and stopped. Multiple dashboard lights and check hybrid system on LED display. Power off car, and back on twice and got the same error on display. Found that car could move on EV power and I got it into a safer location at an adjacent parking lot. Had vehicle towed to repair facility. As a driver this was disconcerting as I could not clearly determine if the car was at all driveable. …”
NHTSA complaint #11141949, filed 2018-10, 113,000 miles“I was making a left turn at a very busy los angeles intersection and during needed acceleration to turn, the Prius lost power for a full second and then power came back slowly and I barely made it through the intersection, a t bone collision was imminent, and I missed getting hit by inches. All the warning lights on the dash illuminated and I was frazzled. The hybrid battery was 2/3 rds full at the time. There have been other instances where the car lost power for brief moments when the hybrid battery was low and didnt think anything of it at the time. …”
NHTSA complaint #11269305, filed 2019-10, 158,000 miles“While driving at ca freeway speed (65mph) the car goes limp. The accelerator fails to work and even flooring the vehicle makes no difference. At this point the speed of the vehicle decreases and I have to immediately pull to the shoulder. The check hybrid system alert shows on the dash and also electric power steering and check engine light. This issue has been going on for the past year and I have taken it to several Toyota dealerships with no resolve. I have spent a total of $4500 without Toyota of vallejo or the now bankrupt Toyota of fairfield solving the issue. …”
