Failure Date: 04/04/2018

The vehicle was having issue with the steering locked up when turning with motion about 20+mph. The hybrid system is not as advertised the 50mpg in any way as it only gets average about 35mpg. The vehicle has 87000 miles and the old symptoms from second generation followed suit with it. The dash went totally off when weather is cold and suddenly turned back on when it gets warm. I had driven a few miles without the dash on and it was a bad experience since I cannot figure out the speed or what is going on. The steering is the major issue as we dare not to drive the car and the technicians from the dealer said nothing wrong with the vehicle but third party technicians recommend to take to Toyota for recall. U turns are the worse that locked the steering and the car almost come to a stop with beeping alarms.

Failure Date: 03/22/2018

My mother has a 2008 Prius that has two serious issues that Toyota has acknowledged and even offered to fix under what they call a support program. Sounds great right? here's the problem. 1. She never received a letter notifying her of the problem and that it needed to be fixed (and only now that the issues have become her issues is she aware there was a recall and 2. Toyota set a time frame to fix these issues which she is now past. Again, sounds like they tried to do the right thing? the first issue is an internal leak causing her brake booster to malfunction (which is a Toyota issue, not an age or wear and tear issue) and the second issue is that there are no lights on her dash board(combination meter) which means that for a Prius, there is no way to tell your speed or gas levels. So take that in. She has a car, that has two major issues, one of which Toyota fixed up until Dec of 2017 and the other Dec of 2016 and are caused by faulty parts and labor by Toyota, and they will no longer fix these. The break issue cost $2400 and the dash $800. For an issue that is caused by Toyota not the driver or wear and tear and is a serious safety issue. This is the kind of company Toyota really is. Several years ago my mom received about 14 letters stating she needed to come in and replace her floor matts because they were part of a recall. Floor mats! she's received recall issues on her door lock among other things that she promptly had fixed. She took her car to the Toyota dealership many times and no one ever mentioned these issues or "support programs". But breaks and dashboards aren't as important as floor mats or door locks. I would love for Toyota to explain to me and everyone else, how something they acknowledge is a Toyota issue, has an expiration date to get fixed by them.

While driving on the highway, the instrument panel cluster on our 2010 Prius went out and we were without a functioning speedometer or gas gauge for the remainder of the drive. This problem has happened to many other 2010 Prius vehicles and Toyota refuses to warranty this extremely costly repair, which causes many drivers to use their vehicles without a speedometer for extended periods of time.

Our Prius has been losing power. It has 68k miles and we are the original owners. Driving at hwy speeds we noticed we have to push hard down on the gas just to get the car to maintain highway speeds. Hills are even worse. We are also still waiting on the parts to fix our headlights. Over the years I have changed the low beam bulbs at least 6 times! when are the parts coming?.

Combination meter is going out on the car. This controls the dashboard lights, meaning that I cannot see how fast I am going or if there are any gauges or sensors lit up alerting me to a problem with the vehicle. Toyota had an extended warranty on this but it has now expired and they want $1000 to fix it.

Starting may 2015 whole dashboard in my car sporadically goes black, I can't see how fast I was going or how much gas I have left or use my backup camera in my car. For about an hour I couldn't even get my car to turn off. This has been happening ever so often since may of 2015 and is very dangerous driving my car in that condition. The other day my car ran out of gas on the bridge from the 5 freeway to the 91 freeway and I was stranded on the side of the bridge with cars passing at high velocity because I wasnt able o see my gas meter. Toyota has known about this defect as shown below and issued a warranty extension for all models 2004-2009 and my car falls 2 months outside of the warranty program and they refuse to take responsibility. .

On Friday, January 12, 2018 I fount the car seat severely smoldering on the passenger side. The care was filled with brown smoke and toxic fumes. The seat was completely burned and melted and toxic residue. Fire department put out fire with water. Car seat heater apparently did not turn off and smoldered all night. Toyota giving me the run around, delaying investigation at least 5 weeks or more. The car was parked in garage, last driven brief distance evening before. Garage now with toxic fumes and residue. Car likely totaled, and Toyota trying to get out of any assistance/responsibility. They are on purpose being very difficult, and forcing me to comply with their agenda, or lose option for their taking some responsibility.

Failure Date: 01/11/2018

Over the past year and over 15,000 miles our 2016 Toyota Prius four touring has experienced sudden displays of warning messages and lights reporting braking power low - visit your dealer; braking power low - stop in a safe place - see owner's manual; pre-collision system malfunction - visit your dealer; anti-lock brake system malfunction - visit your dealer; lane departure alert malfunction - visit your dealer; ics malfunction - visit your dealer; check cruise control system - visit your dealer. The following codes/faults have been detected: abs - c1403, c1407, c1415; parking sensors - c164d, c1a50; blind spot monitor - c1a45; blind spot monitor slave - c1a45; pre-collision system 2 - c1a50; lane-keeping assist 2 - c1a50; ecu - p157800 & cruise ecu - p157800. The warning messages/lights came and went while driving on both city streets and highways. Each time I took the vehicle to the dealer. They could see the codes in memory, but could not replicate the problem. No parts were replaced. The only thing they have done is to take apart and reseat some of the connector cables and then send us on our way telling us to bring it back in if it happens again. We are seriously concerned about the safety of this vehicle and have no reassurance that the problem has been resolved and no reassurance that major braking systems might not be available to me if it occurs again. I contacted Toyota customer assistance with no change in their position. I am currently negotiating to trade the vehicle in as I am not comfortable that the problem is resolved and deeply concerned that it will happen again. I have shared video of the warning messages and lights with the dealer, but am unable to upload video here.

Failure Date: 12/27/2017

On my way home I suddenly saw a sign on the screen "check the hybrid system. Stop in a safe place". I pulled over, smelled smoke and saw smoke in the rear. I opened the trunk ans frightened by flame. I pulled things out and covered the flame with two big towels and succeeded in putting it out, although I got burned on my fingers. I called geico. They sent a towing car and it took my car to my apartment. When geico took my car to a collision center, they said it is total loss after inspecting it. I claimed it to Toyota. They inspected it, but said that there was no evidence that the car had electrical or mechanical defect. I did nothing but driving the car, but it caught fire. Whose responsibility is that? I believe the producer should take the responsibility but they do not. Where can I be compensated for the loss?.

Failure Date: 12/25/2017

I was driving my 2009 Toyota Prius on a very cold day (roughly 10 to 20 degrees f). The red brake warning light was on, along with the abs, vcs and yellow "!" lights. The brakes were extremely soft for about the first 5-10 minutes of operation. I would push the brake pedal as far as it would go (it would not go all the way to the floor) and the brakes would seems to be engaging at about 30%-50% of their normal stopping power. After the vehicle warmed up, the warning lights on the dash went away and the brakes began operating normally. The following week, my wife was driving the vehicle on another very cold day (again probably about 10 degrees). She stated that the above mentioned lights stayed on for her entire commute (less than 10 minutes) but that when she arrived to work, her brakes were not working. She described that she pressed the brake pedal as far as it would go, but the brakes did not seem to be fully engaging. She stated that she nearly hit a wall as she was pulling into the parking lot at her work. I have found similar issues listed on Prius forums online. Perhaps it is a electrical or computer problem as opposed to a problem with the brakes. We have never had the problem when the temperature was above 25 degrees.

We were driving on the highway at about 70 miles per hour when the reading lights and dashboard flashed on and then off in a matter of about 5 seconds. The dash showed a triangle indicator light with an exclamation point. The dash also seemed to reset and showed the display as is the car had just been turned on. This incident happened twice within a 4 hour period. Once on the highway and once on a back road going about 40 mph. The car did not stop either time, but it is still concerning.

The headlights go dim and /or shut off as I am driving. This problem usually starts with the right headlight shutting off and sometimes both will go dim or shut off completely. Both lights work initially on startup and shine bright at first but immediately dim to a lower level and then as I drive they will dim or the right light will turn off or sometimes both turn off all together. They will come back on if I turn off and back on the headlight switch.
