1 Engine Knocking Noise problem of the 2013 Toyota Prius

Failure Date: 12/23/2019

From day #1 these issues were present on 2013 Prius five: lka suddenly stops car over minor car movements ahead,major knocking sounds from engine on cold starts, brake pedal hits floor and suddenly locks up! I now have 20k and hardly drive it now trips skid icon?, bluetooth is erratic, cruise control shuts off or won't turn on when its wet out, drizzles or rains! is my Toyota my mother warning me not to drive in bumper to bumper traffic, avoid rain or snow, not to use electronics or listen to music while driving and if I use the tech in this 36k Prius five its causing me to drive like a 90 yr old with bad eyes and even poorer judgement! it's a wonder why some people hate Prius drivers. . ! the 12v battery dies every few days so I must keep it plugged in. I even wrap my fob in foil at home and keep it as far from car as possible to not wake up the car if I walk by a window close to its parked to avoid power drain. Toyota tells dealer everything is okay? . . . . In what world would anyone pay to have a car like this and tell customers its okay?? I have to drive and other people's lives are in danger! my son is now getting ready to drive and I can't imagine him fighting the controls that Toyota built in to keep him safe! I used to manage a Porsche dealership and raced on many tracks and can drive fairly well and don't like to complain but after my recent issue and research found a lot of common problems with others so I chimed in. .

2 Engine Knocking Noise problem of the 2013 Toyota Prius

3 Engine Knocking Noise problem of the 2010 Toyota Prius

Failure Date: 02/07/2018

At about 125k miles, my Prius nearly ran out of oil between services, and I religiously service my vehicle. I burned 1 to 2 quarts between services since. At 272,408 miles, I just paid $5751. 59 for a complete engine rebuild. . . Rest of car is in great shape. Oil consumption problems were known by the dealerships, but I was given no recourse except dealing with it. Latest issue. . Check engine light on, misfire on cylinders 1 and 4 (progressing to all), horrific knocking noise with sound of rushing water upon start-up. Eventually, (once the cylinders fired significantly) the engine could run satisfactorily for the remainder of the drive. . . Until the next start. Early on I read that Toyota knew of the under-engineered motor of the 2010s, but I have not received anything announcing a recall or care to fix their engineering issue. I have my service records to validate the care I've given to my car. The date of the engine rebuild is what I will provide as to when this happened, but the oil consumption began years ago.

It was audible from several feet away from the car. On the second time, it was accompanied by a warning light to put the car in park. Vehicle was towed to the dealership.
