Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 2003 Prius (first gen, from japan), has been thru a few recalls - 1 was to seal the battery better early on (04ish), then it was given new pinion shaft nuts. Latest issue has been an issue all along, just not diagnosed/fixed til now. Sometimes the 'check engine' light would come on, with the car/! /triangle graphic on touch screen. This time it didn't go away. Long story short, it was the electric water pump that needed to be replaced. …”

“Toyota consumer safety advisory potential floor mat interference with accelerator pedal. I've had issues with the floor mats in my 2003 Prius almost from the beginning of owning my car. When I looked at the illustrations on the Toyota web site it was clear that the retaining mechanism it identical to that of the 2004 Prius. Yet the model is not being covered by the recall. Please consider expanding the recall to all affected models and model years.”

NHTSA complaint #10285859, filed 2009-09

“Consumer 2003 Prius passenger side tire blew out. The consumer thoroughly read the owner's manual on hold to change the tire. The supplied jack was used to raise the car. When the vehicle was raised a short distance the jack slid forward and the car dropped to the ground. The consumer attempted to raise the vehicle three more times with the same result.”
