NHTSA complaint #11280513, filed 2019-11, 100,000 miles“I tested fuel tank capacity since driving range has substantially decreased from new car status. Fuel capacity now 9.2 gal, versus 12.4 at purchase. The fuel bladder has shrunk, substantially reducing driving range. This shrinkage occurred between 10/15/2005 and 2/24/2011 when I tested it. I am informed by Toyota that replacement fuel bladders will also gradually shrink. No metal fuel tank is available as a replacement. This is unacceptable.”
NHTSA complaint #10680167, filed 2015-01, 76,709 miles“My wife was driving our 2005 Toyota Prius today and the accelerator locked to the floor. The car continued to accelerate even though she was braking. She was eventually able to get the vehicle to stop. The accelerator was not stuck under the floor mats. She had to pry the accelerator from the floor.”
NHTSA complaint #10472409, filed 2012-08, 62,000 miles“While driving in the rain on the freeway, the car de-accelerated suddenly after all the lights lit up on the dash board. I could not make the car go. I managed to maneuver it close to an offramp(dec 2013). Towed to north hollywood Toyota, paid over $800 to fix items I was told would fix problem. It did not!!! 4 months later on the freeway again, same thing happened. I cost off ramp and had the car towed to another dealer.(march-april 1014) left it for a week, they said it runs, cant find a thing. …”
NHTSA complaint #10611356, filed 2014-07, 80,000 miles“As the hybrid battery for my 2005 Toyota Prius began to fail, I noticed a degradation in my braking ability. My brakes would slip out on me unless the gas engine was running' in driving that relied on the battery, I essentially had non working brakes. When I had the hybrid battery replaced, a multi-point inspection revealed my front brake linings at 8.9mm and my rear drum linings at 3mm (which is still in excellent range). This was clearly not a case of worn out brake pads; and replacing the hybrid battery restored my braking function when running on battery power.”
