36 Equipment problem

Failure Date: 04/01/2018

Took my car into dealership because of a noise it would make when I started to brake and when I was stopped at a light. The car would also vibrate and shake. The dealership told me the abs actuator needed to be replaced which would cost over 4 grand! I couldn't believe it. I'm scared to drive the car now.

37 Equipment problem

Failure Date: 03/28/2018

My husband was driving the car preparing to turn to enter the freeway when the Prius lost all driving power spontaneously at the same time prompted with a warning on the screen �check hybrid system and park in a safe place�. The car lost all driving power including power steering but my husband was able to glide the vehicle across several lanes to a parked position before the freeway entrance. The car never resumed its ability to drive despite turning it off and an attempt to restart. The Prius was towed to the house and towed again to the dealership the following day for an assessment and repair. As a Toyota customer, we were informed the vehicle had experienced inverter/component failure. My vehicle had a recall years earlier to reflash software in the Prius inverter, but this did not resolve/prevent the spontaneous inverter failure we experienced on Wednesday, March 28, 2018. It has been brought to my attention that Toyota corporation is aware of several customers reporting similar or near identical circumstances, but are not issuing a recall to prevent this from happening to a Toyota driver on the road. Toyota is agreeing to replace parts at no cost to me, with no guarantee this will correct any inverter failure. I have requested the system be replaced based on Toyota's corrective action on the newest Prius models, but they have denied my request. If Toyota is acknowledging cost for this vehicle failure, why is it not a recall? if Toyota has made attempts to correct this vehicle failure in newer Prius models by installing improved inverter systems, why am I being denied the safety of also having an improved and new inverter system installed in my Prius after what we have experienced and reported to both the Toyota dealership and Toyota corporation? please investigate before injury or fatality comes from this corporate neglect of an identified problem.

38 Equipment problem

Failure Date: 03/01/2018

I own a 2012 Toyota Prius. On the dashboard the brake light, the abs light, and the traction control light are all on. In addition to the warning lights the brake accumulator pump is constantly buzzing without ever stopping. I took the car to our local dealer and I was told that it is a leaky accumulator pump defect. I was also told that this is not a ware and tear item and that it is in fact a faulty item from the manufacture. I called Toyota corporate for help but I was told that the car is out of warranty and that there is nothing they can help me with. My main concern is the safety of my family and I really hope that Toyota does in fact do a recall on these faulty items as it is a real hazard to safety. ## VIN passed ## Toyota Prius 2012 ##.

40 Equipment problem

Failure Date: 11/01/2017

Excessive oil consumption. When I checked the oil level before the next scheduled oil change, I found no oil on the dipstick. On my last oil change, I was not told I had a problem with my oil consumption. Had to buy oil in a hurry as I did not want to drive the car without oil.

41 Equipment problem

Failure Date: 03/03/2017

2012 Toyota Prius has been consuming large amounts of oil since 89000 miles. Dealer completed an oil consumption test, of course if passed. Dealer stated rave4's and camry's have had same issue and they issue recalls. Toyota has yet to accept responsibility and replace the pistions to correct the oil consumption.

42 Equipment problem

Failure Date: 03/03/2017

The design of both Honda accord and toyato Prius, and likely othernew model cars, makes it very difficult to see when backing up. The back up camera is placed such that it is easily covered with road debri (dirt and snow) so it often useless. The deisgn of windows, seat and camera do not sufficiently allow one to see over ones left shoulder. Perhaps this is more because I am barely 5'1:" and the car's safety forbids using a seat cushion to raise me higher. Backing up is frightening but many car lots require you to pull in front forward so pulling out when pedestrians might be behind or other cars backing up is a serious problem. I did not have this problem when I drove a 2007 Ford ranger or a 1995 le baron convertible. So far I have managed to not have an accident but think cars' designs do not consider this situation sufficiently for safe driving. .

43 Equipment problem

Failure Date: 01/17/2017

While stopped in a parking lot, foot brake pressed,transmission in drive, when opening drivers door and foot brake released car still moves forward. It should go into park automatic but does not.

44 Equipment problem

Door locking mechanism, security issue, vehicle will not lock due to faulty lock actuator--- may effect other actuators. Vehicle stationary and on start up for motion.

45 Equipment problem

Failure Date: 03/14/2016

My Prius was just fine then one day it stalled while I was driving in the middle of the free way. I took my vehicle in to elmore Toyota in westminster, CA, they found it had a failed inverter and it was still covered under warranty. It took 2 weeks for them to fix it, but when they returned my car, the slip indicator was now on and would not turn off. They claim it was like that prior to the failed inverter, this was false, my car was running perfect. They then wanted to charge me nearly $1k to fix a problem I did not have prior to failed inverter. I feel the situation was connected but they refuse to cover it.

46 Equipment problem

Failure Date: 11/20/2015

My passenger side sun visor just completely fell out while driving down the road. It has rarely been used (my car is a 2012 with high miles and most of the time I travel alone). This could have easily caused a distraction or crash. I noticed that there are several complaints about other Toyota models / years.

47 Equipment problem

Failure Date: 10/01/2014

I felt a loose noise behind the wheel of the car. Took the car to service where I had bought it and they certified that the steering shaft needs a replacement @ 47,000 miles. Prius models from previous years have a recall for this issue. The issue is not solved, yet they continue to have the defect and no other recall has been issued for the same problem. The repair estimate is around 500. 00 I have had about ten cars in my life and in none have I ever had the worry or not even the sound of a loose steering shaft. We are talking about the steering wheel. . . And I have a family of 5.

48 Equipment problem

Failure Date: 09/20/2014

I have replaced 5 evap charcoal canisters at $590 per canister.

49 Equipment problem

Failure Date: 03/03/2014

A dead mouse was found in the cabin air filter. The dealer charged me to change the filter and clean out the air system. I thought it was a fluke. I had several unexplained messes in the car (blamed my children) then found a live mouse in the glove compartment. Opened up the glove box all the way and exposed what was behind it and found the mice had shredded up the insulation around the wiring system. We removed a gallon sized baggie of insulation that made a very cozy and large mouse nest. Now the dealer wants to charge me again for a mouse issue. Where will this end? in reading on the internet, it appears Toyota Prius has a big problem with not sealing up the car for vermin. Hanta virus is a very big concern for me, as is the thought of a mouse scurrying near or over me while I am driving.

50 Equipment problem

Failure Date: 01/08/2014

After starting the car, it would not go into gear. The dashboard was lit but I could not get the car moving. After fiddling around for sometime, it finally clicked and I was able to go into reverse. The car functioned fine until later that day I made a drop-off stop and the same thing happened. The dash board was lit but I could not get the car moving. I was stalled almost in the middle of the road. The next day I took it to the local dealership and they did the most extensive computer generated diagnosis on the car but could find no indicators of the problem. I reported this to Toyota headquarters who said they'd investigate but there is no internal system for reporting back to me on their findings. I did research on the consumer reports website and saw others have reported similar problems. My fear is getting 'stuck' in unwanted times and undesired locations. The fact that the company doesn't recognize the problem is troubling. I plan to get a new car rather than worry about this one.

51 Equipment problem

Failure Date: 03/29/2013

There is a tripling of light sources through the front windshield from things such as oncoming vehicles headlights, vehicle taillights, emergency vehicle lights, street lights, intersection stop/yield lights and any other strong light source. The issue is apparent at all times however the issue is significantly acute in the evening hours as there are more light sources during the dark.

52 Equipment problem

Failure Date: 10/20/2012

Vehicle is manufactured without any regard for preventing mice from entering the passenger interior--- air intake vent under windshield and 2 rear decompression vents located in the rear cargo compartment above the wheel wells are open to the exterior allowing unimpeded access to the interior of the car. Had mice in this car 2 weeks after purchase in 2012 and have been dealing with this problem for 7 years. Just recently, had Toyota install 1/4" hardware cloth over these 3 areas and this should help significantly to prevent entry. All preventative measures to prevent mice entry have been diligently taken by me, without success. Mice can make a person very sick. Their excrement carries hantavirus. . . . . And the mice carry ticks, which can lead to lyme disease. Simply manufacturing the car with these vents properly screened would greatly reduce the chance of occupants contracting a serious disease. The mice also do a lot of damage to the car itself, in my car the driver seat belt was chewed, and I have had to replace the cabin air filter several times because of nesting in this compartment(after having been unknowingly breathing the mice excrement as the air passes through this filter on its' way to the interior. Toyota needs to be pressured by your agency to correct this very serious health hazard that their car is presenting. Their is no legitimate reason for this situation to exist. The cost to Toyota would be negligible. The benefit to all Prius owners would be very significant, likely preventing many cases of disease. Please take this situation very seriously, as is the case. I also will be calling you to discuss this over the phone. Thank you for your help to correct this problem!.

53 Equipment problem

Failure Date: 09/26/2012

Fuel indicator on the dash showed 3 bars for remaining fuel. Vehicle ran out of fuel despite showing 3 bars. Oftentimes after tank is filled it only illuminates to 1 or 2 under the top bar instead of showing a full tank. There is obviously a problem that the car is not accurately reporting the fuel level.

54 Equipment problem

Failure Date: 07/25/2012

When going from park to drive forward, the car slips into reverse!!! I've taken it to Toyota multiple times and they say they find nothing wrong! I have to be very careful to be sure the car is actually in drive before moving it or I could back into something or someone by mistake.

55 Equipment problem

Failure Date: 01/13/2012

When starting to drive the car after is has been sitting for about 3 hours and especially first thing in the morning, the vehicle makes a groaning noise which seems to be coming from the left rear tire area. It lasts for about the first 50 feet and then it stops making the noise. This has happened with temperatures varying between 40 to 75 degrees. When it is really hot in the morning, the noise is not present. The dealer has looked at the vehicle several times and they say that this is a national problem with no solution. I have owned this car for 4 days short of a year with 12,250 miles on it and it does it all the time. This is very frustrating because the car is fine otherwise.
