Failure Date: 04/17/2017

When vehicle is turned on, instrument cluster also known as the combination meter, fail to turn on. This issue is very concerning due to the overall computer controlled functions of this vehicle. The speedometer, trip meter, odometer and other functions are not functioning due to the failure of the combination meter. Functions that are considered safety items such as the power brakes, power steering, anti lock brake system, speedometer, lights, etc. There is an issued warranty covering the issue up to a certain amount of time however since it is not a wear and tear item it should be covered by the manufacturer regardless. After vehicle is eventually ignited, combination meter does not illuminate and when attempting to turn off the vehicle, it fails to do so which also includes not being able to remove the key. I was advised by a Toyota mechanic to access the safety override by holding the power button however that procedure does not work all of the time. I am very concerned about this issue due to my safety and drivers around me and their safety and hopefully this issue can be avoided before a possible a catastrophic accident happens.

I've had two Toyota Prius in my lifetime, a 2005 and a 2010 Toyota Prius, both have had the same issue where the engine would eat up all of my oil, I would have an oil change done and less than 2 weeks later I would have to check the oil gauge rod and find that the oil levels were below the bottom line, almost empty! the engine would be burning oil at such an alarming rate that I would repeatedly bring the vehicle to Toyota for oil changes. I'm very unsatisfied with my Toyota Priuses. My car is currently at 166,384 miles and the engine cylinder has now given way and also the hybrid battery. I've gone only to Toyota dealerships to have pristine consecutive service and no third party repair facilities have provided service. I am located in souther California in san diego. I have spoken to many other Toyota Prius owners and if you do a google search online as of (04/10/17) "Toyota Prius engine oil consumption" you'll find many forums with "excessive consumption" from many other users. Once you reach past the 140,000 mile mark, your car is pretty much done. Consider buying a new one. Toyota Priuses and their engineers have to come up with a way to satisfy current and future Prius owners as many of us will find that there will be many problems and issues down the road.

Car was brought to Toyota of hollywood, florida for a new battery. When it was returned none of the dashboard was working: no speedometer, no gear shift indicator, no fuel gauge, no engine warning lights, no backup indicator beeper. Additionally it takes many tries over minutes to turn the car off and it locks the rear hatch which cannot be opened with the inside door unlock button. Obviously this is a dangerous and hazardous situation which I expected that the dealer and manufacturer, Toyota, would take care of immediately. They claim that the car is out of warranty and won't fix it. It should be part of a vehicle safety recall.

My front right headlight turns on and off randomly. Now it doesn't turn on at all. I replaced the bulb and it still doesn't work. Many people have had the same problems and have also fiiled complaints because Toyota doesn't assemble or run the electrical circuits properly.

Tl- the contact owns a 2012 Toyota Prius. The contact stated that while parked, there were rodents entering inside of the vehicle. The contact stated that the cabin air filter did not have a mesh grill which was allowing the rodents to enter through a hole in the cabin air filter and then into the glove compartment console and into the interior of the vehicle. The dealer was contacted and informed that the wires were soy based causing the attraction of rodents to the hood of the vehicle however the vehicle was not taken for an inspection. An independent mechanic was also contacted who confirmed that the cabin air filter did not have a mesh grill which resulted in the rodents entering through a hole into the cabin air filter and enter the glove compartment console to the interior of the vehicle. The vehicle was then taken to a mechanic where a hardware cloth grill was installed on the cabin air filter. The vehicle was repaired and rodents were no longer entering the vehicle. In addition, the contact was required to clean the feces remaining in the interior of the vehicle utilizing a mask, gloves, and disinfectant and in order to avoid contact with a virus from the feces, the contact was advised not to vacuum let the virus become airborne. The contact was concerned that the rat feces in the vehicle could result in a fatal disease in the event a child would ride in the vehicle and was unaware of not to eat the feces. The contact was concerned that if rodents entered though the a/c unit and defecated inside and activate the air condition unit if there was feces a virus could become airborne. The manufacturer was notified of the failure then informed the contact that the failure was not covered under warranty and that the failure was an outside influence which was not their responsibility. The approximate failure mileage was 40,000. The VIN was not available. Djr.

My dashboard went darking including the speedometer and it appears to also disable the odometer when this happens. This happened after stopping to fill up for gas. After restarting the car the dashboard will no longer light up. It looks like you can temporally reset the faulty part by disconnecting it from the battery and reconnecting it. This issue is regarding a problem that is known to Toyota, they have extended the warranty for this part to 9 years/unlimited miles. My Prius was effected after 9 1/2 years putting me past the warranty they extended. The problem is with the "combination meter", it appears to be caused by a bad solder during the manufacturing process. Research shows me this effects 2004-2009 Prius models and it looks like most Prius will run into the issue at some point. I'm not sure why this hasn't been a recall as no speedometer is obviously a safety issue, the problem is widespread and Toyota seems to acknowledge the problem with their warranty extension. I imagine it took me more than nine years as we only have 90,000 miles after nearly 10 years of ownership. A google search on Toyota Prius combination meter problem will bring up a lot of information on this. Thank you for your time, mike holiday counsoul23@hotmail. Com.

I have contacted Toyota concerning the failure of a combination meter in my daughter's 2007 Prius. This happened on startup. This item is related to the display screen. As mentioned in their warranty policy bulletin pol 12-05 dated 10/12/12 a failure can result in the screen going dark. If this happens in the night this can result in a serious safety issue both because of the unexpected and immediate distraction and the loss of critical visual information. Their warranty bulletin does not seem to address the seriousness of the matter. It is my opinion that this item should be an immediate recall. My 2009 Prius is one of those mentioned in their bulletin. Though I have not experienced any failure, I became aware of this issue with the recent event that my daughter experienced. Neither I nor my daughter has received any notification from Toyota. I am a fan of the Prius as is my daughter, but this issue is too serious to simply ignore. It is my hope that this will be addressed with Toyota.

I was driving down the road at 65 mph when the electronic instrument panel went blank I could no longer tell how fast I was going, how much fuel I had left or if any of the warning lights ( low tire, low oil, running high temperature, etc. ) were on. The display originally went out in 2010 but the Toyota dealership told me how to correct it. It has happened 2 more times since then the latest being the third. This time it has rendered the car unsafe and undriveable. I found out searching the internet that Toyota has been aware of this problem since 2009. Siting t-sb-0172-09 combination meter intermittent display which affected Prius from 2004 to 2009, for 3 years 36000 miles. In 2012 they issued a warranty enhancement program for the same problem combination meter intermittent display and then became 9 years from date of first use or before September of 2013 with unlimited mileage. Since it was a warranty enhancement instead of a recall they did not send notices to everyone with Prius about this defect. Since notice was not supplied I was one of I am sure quite a few who fell through the cracks. I contacted Toyota about the situation and was informed that Toyota would do nothing to correct the problem.

This 07 Toyota Prius dash instrument lights will go out whether stationary or in motion and or not come on at the start of the vehicle. The car can be driven but there is no way to reference the speed or vital functions of the vehicle when this occurs. Also the vehicle will not turn off when the power button is pushed when the dash is inoperative unless you hold the power button down for an extended amount of time. Toyota knows about this issue but the time limit on the unpublished extended warranty that I was told has expired. We bought this vehicle new in 07. This vehicle started doing this recently. This should have been a recall item on this vehicle due to the potential safety issue.

The contact owns a 2005 Toyota Prius. The contact stated that there was a manufacturer service campaign for a wheel alignment. The dealer serviced the vehicle for the repair. Shortly after the repair, the instrument cluster display panel went blank. In addition, the vehicle failed to shut off twice and had to be left running due to the failure. The vehicle was taken back to the dealer where it was diagnosed that the combination meter needed to be replaced. The contact was provided with a loaner as the dealer further tested the vehicle. The manufacturer was notified of the failure and the contact was waiting on their recommendation concerning the dealer's repairs. The failure mileage was not available.

As I was coming back from livermore to san jose down the sunol grande last weekend, my dash lights suddenly went out meaning I had no speedometer or wait to tell how much gas I had and the abs and stability control went out while going 65 miles an hour down a steep hill. Luckily I was able to get home and don't ask me how I figured out to get the car to turn off. I called the one 800 Toyota number and it turns out there was a problem with something called the combo meter on these cars and it had an extended warranty for a total of nine years. My warranty expired they said April 2016. This seems like a serious safety issue that Toyota should cover if they are concerned about their customers safety.

My 2008 Toyota Prius's dashboard indicators (odometer, warning signs and everything) showed symptoms of disappearing momentarily during second half of the year 2016. Upon restarting, it used to come back. However, on February 18, 2017, the dashboard light won't come back even after multiple time restarting. Drove to work in that condition hoping the dashboard indicators will come back but they didn't. Made an appointment with dealership to check it out on Monday. Before the appointment, the indicators came back so I cancelled the appointments. When discussing the problem with a friend, I was told that Toyota is aware of this problem and have extended the warranty for such repairs. Upon hearing this, I called Toyota customer service to inquire and was told that the extended warranty is expired and can't fix the problem under warranty. Driving without the dashboard lights is a safety issue that Toyota shall address for all affected vehicles.
