Toyota Prius owners have reported 726 problems related to electrical system (under the electrical system category).
Afternoon 07/11/17 while driving downhill @ 50 mph my 2006 Toyota Prius turned off- no steering, exterior lights, dash/computer lights, radio- except for front interior dome light. No warning lights prior to or after car turned off. I was able to brake (very stiff brakes) & pull over. Replaced 2015 12v battery hoping for quick fix. Car still would not turn on, could not be towed on flat bad for fear of damaging transmission. Car was towed to closest mechanic. On 07/12/17 independent mechanic said both coolant pumps failed and the leaking shorted a fuse and turned off the car. Every time they attempted to replace fuse it would pop fuse again. Mechanic replaced water pump (including coolant/antifreeze) & inverter electric pump (including inverter cooler water) & changed auto transmission fluid & filter ($1,115). Early morning 07/14/17 dash display would not light up when car was turned on- no speedometer, odometer, gas gauge, reverse camera. (happened couple of times in past but could not duplicate for dealer. ) while driving to Toyota dealer I noticed computer screen stuck @ 48 mpg & 61 miles driven, but never increased miles as I drove 18 miles or updated mpg calculation. Refused to turn off car until someone from Toyota dealer looked @ dash to verify condition. Toyota dealer says combo meter (combination meter) failure, which is not recall but "campaign" that expired & repair costs $1,111. Motherboard part can take up to 3 weeks but car cannot be driven while Toyota "burns" my computer's information into new computer part. Toyota dealer provided loaner car until repair is completed. On 07/14/17 called Toyota & filed complaint about water pump & combo meter. Toyota says hybrid electric water pump campaign did not affect my VIN, which I do not believe. Toyota says combination meter campaign expired for my VIN. Pending call back from Toyota at this time.

Dash board keeps beeping, yet I have replaced the key battery 3 times and now dealer says key not detected, yet car runs so the key is detected but the beeping will not stop. Took to dealer paid 89. 99 for diagnostic per dealer. Dealer now says the left harness needs replaced for $1802 plus tax. I feel manufacturer should allow consumers who bought there product be given information about history of faulty electrical wires even when it is not a safety hazard. Just turn off the beeping noise if that is the only issue. Mileage 58847. . .

Faulty combination meter, which displays car speed, odometer, fuel level, and turning off the car. Toyota extended their warranty for 9 years but won't fix the known issue anytime past 9 years. Mine failed 9 years 2. 5 months. Toyota customer service said that they have replaced a whooping 669,000 combination meters.

The passenger side headlight intermittently turns off and on. The lightbulb is still functional. This will happen wether I'm driving or stationary.
The dashboard went black with no visibility to speed, fuel tank gauge, or other instruments in this panel. Also, car would not power off. The instrument panel went dark while I was driving on a city street. The engine power down problem occurred in my driveway upon my return from my city use.

Airbag warning light illuminates. Toyota service techie's diagnostic showed a disconnected spiral cable. Techie explained that the spiral cable has electrical connections to the driver's airbag module and the driver's air bag would not deploy in an accident. He said I should install a new cable spiral assembly kit (aka "clock spring"), part # 8430747020 at a cost of nearly $1000, including over $700 for the part. I did some research. Part # 8430747020 was installed in many Toyota vehicles, and has been recalled for the same problem in the corolla, matrix, highlander, tacoma, rav4, and yaris. See safety recall e0m (e1m) April 2015, update 5/12/14. The Prius is not mentioned in the recall, although my car has the same exact problem with the identical part, and the Toyota service supervisor agrees it is the same problem and part. I explained this to the service technician and supervisor, who called Toyota, and Toyota offered to cover 50% of the cost of the part, and none of the labor cost. I asked whether they could do the same fix in my car as they do on the recalled vehicles, namely installing part # 04004-07122, and they declined. See technical instructions for safety recall e0m spiral cable replacement. Toyota should be recalling my car and fixing this problem at their expense, not just reducing the cost of the part. Second, they should not be replacing this defective part with the same defective part. They should do a fix that will last. I assume the fix they've done on all other vehicles, with part # 04004-07122, would work for my Prius. They refuse. Fyi- the airbag light has been on and off for years, and seen by Toyota during that period. This particular problem was diagnosed may 1, 2017. They believe the previous airbag warning lights were unrelated to this particular issue.

Pasdanger headlight goes on and off without cause and at will.
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.
Interior lights are extremely dim. Affecting tons of Prius owners. Shift knob was working and has not gone out as well. Too expensive to replace the light bulb in shifter knob. No solution for interior dimmed lighting that lots of people are complaining about. Dealer said they know of the issue and it exists in all 2007 Toyota Prius models.
Lights would go off while driving, at first 1 side or the other, acouple times both went off with the last time almost causing a collision and I had my kids in the car.
We purchased a 2017 Toyota Prius on January 29th 2017 and on March 22nd 2017 the car caught on fire out of no where. The car was parked and off when smoke began to come out from the around the shift changer and the touch screen area. After a few seconds the car was completely on fire.
Smog check failed because of obd bulb check failure and obdii failure. Service fault codes are u0100 lost communication with ecm/pcm "a" and u0111 lost communication with battery energy control module "a. " car only has 60,000 miles.
Inverter water pump replaced at 75000 miles under recall and failure. Same pump failed again at 146600 miles. Replacement pump lasted less miles than original. Pump design or manufacture is not adequate for service. Diagnosis was pump seized during expressway driving (65 mph). Did not cause an immediate stoppage but vsc warning caused reduced controllability.
Dash lights showing speed, fuel level and odometer stop functioning intermittently. So far it happened once on start up after a cold night. Dash lights came back on later in the day. Vehicle was not driven, though everything else seemed to work ok.
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.
A warning light came on for eps and 30 seconds later it stalled and would not steer or move. I was driving at 6pm on a Friday in major traffic.
The vehicle combination meter sporadically will not turn on which prevents the display of the speed of the car. During this condition, the fuel economy will not display, the car may not be powered off by normal procedure, and the fuel gauge, drive train mode indicator, and odometer are not visible. This has occurred for the past 2 years, primarily during cold weather, but also during warm weather, and I have a video recording of this problem while operating this specific vehicle dated February 20 2017. Toyota will not honor their own warranty extension described in their document pol12-05, related to TSB t-sb-0172-09, stating that the dealer must be able to reproduce the issue in order to cover the replacement. Toyota's document pol12-05 specifically states "this condition is primarily found in cold weather climate conditions. When the vehicle is brought to your dealership it may no longer be in a climate which allows duplication of the condition. If this occurs, please verify with the customer that the experienced condition is in accordance with this warranty extension and proceed with replacement of the combination meter. " on 5/12/2017, andrea n. (would not provide last name) with Toyota customer experience center, assigned me Toyota case # 1705121649 and stated that "the dealer must reproduce the issue in order to cover replacement under warranty" despite the Toyota letter explicitly allowing for warranty replacement when the condition cannot be reproduced by the dealer.

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.
