Recently reported ELECTRICAL SYSTEM problems on 2014 Toyota Prius

Sometimes the car nothing in the car will light up nor will it start. we replaced the battery in the rear. we replaced the fob battery. sometimes we open the driver's door and shut it and it will make the dash lights go on and the car will then stat when the start button is pushed. the car remains dead sometimes no matter how many times you open and close the drivers door. come back 15 minutes later and the little red car light on the dash is blinking and the car then will start when start button is pushed. other times the litle red car light on the rightside bottom of the dash lights remains off and car remains dead.

The driver door and passenger door locks only work sometimes and it seems to be a electrical issue because i have noticed other odd things with the electrical in the car

The car brakes failed at low speeds (10-15 mph) and bumped into the car in front in a stop-and-go traffic on the wet freeway after a recent rain. the brake pedal went all the way down to touch the floor, as if the brake pedal was disengaged from the braking system and the abs light did not turn on at the time of braking. the car was driving in the straight line and immediately before this i was able to successfully brake the car on the very same trip. so the problem is intermittent. this is the second time with this car, as my spouse also experienced the similar brake failure at even lower speeds (<10 mph) resulting in touching the car in front and minor scratch on the bumper. it was a dry day then and almost similar circumstances. associated geico claim number is 0423477190101054. we opened a case with toyota to check the data recorder. associated toyota case number is 181112370.

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.

Electric burning smell emanating from front of car smell coming questionably through air ducts which comes/goes and is noted upon starting car and for five minutes duration after start. increase incidence of burning smell on days when ambient air temperature is 90 or higher. i wonder if i am inhaling toxic fumes . will consider report of problem to the epa. checked by pohanka toyota in early summer "could not duplicate smell problem" no follow-up. report made to toyota motors per email and to representative as well at toyota. stated " we will report your issue to the administration; "no recommended follow-up. internet search indicates there are several models of toyotas with similar complaints. it is about time there would be a recall and something done about this block below asking when did this happen is forced choice for date(so not accurate reflection of the problem); this has been happening on/off since may 2017 s. i did inform the toyota rep by phone that i would file a complaint with my state attorney general's office and the better business bureau.

Seat belt light stayed on, swerve light occasionally. proved to be rodent damage on wire instruments and blower, panel instrument, antenna assemblies reaching $3,900. vehicle parked outside residential building on public street in cold rainy weather. vehicle in excellent condition. never had such a problem with any other vehicles while living here over 20 years. could soy based encasing around wiring contribute to this? *tr

Rodents chewed electrical wiring making the vehicle unsafe to drive. the electronic sensors were rendered inoperable. the vehicle was parked in my garage for the week end. never had this problem with my other vehicles parked in same garage! repair cost,not covered under warranty was $ 1100.00.

Rodents chewed through majority of the wiring under the hood and build nests in the engine. this has happened twice and i have only owned the car for 5 months and cost me a lot of money for repairs which toyota will not cover and said it is not their responsibility for using these soy based wires that attracts rodents.

Headlights and cabin lights failed to turn off when remote lock was activated. lights were then turned off manually. five hours later, in the parking lot, the car was nearly completely dead. last time it happened, we left it and it recharged itself. this time, it did not recharge itself; it was completely dead the next day. we had to have it towed to the dealership, who "jumped" it and let it sit overnight. they say it now has no problem.

Driving home (approximately 100 mile journey) - the "check hybrid system" light came on and car warnings indicated needed to stop driving and have car taken to service immediately. had car taken to dealer for "warranty" service - was told a rodent had eaten the high voltage wiring insulation - not covered by warranty. have had no evidence of rodent activity at our location, and other vehicles parked here have not had any problems. being told $2700 repair not covered by warranty that i need to claim on my car comprehensive coverage. concerned that if it is rodent damage, is it due to materials used that are attractive to rodents (wouldn't this be a problem for all prius owners), especially in areas that have more of a visible small rodent population? also, don't know how to prove it was manufacturer or design defect - asking dealer to document how they came to believe it is a rodent problem.

This vehicle is a little over 3 months old and has had electrical problems through this period. when put in reverse on occasion it freezes and all the lights on the dash go on and stay on (including the yellow triangle) and the car does not move. the prius c needs to be shut down every time this happens and restarted to work. this has happened 5 times in the last 3 months since purchased new. worse yet, the last time when it was put in reverse (yesterday) all the lights froze on the dash however this time the car lurched forward even though the gear shift was in reverse and the dash said 'r' for reverse. the car was purchased new from the dealer.

I was in a parking lot and put the car in reverse. then i heard a "boom" and i thought that i backed into something, so i quickly put the car into drive. i then felt the car excelerating fast and i was pushing the brake as hard as i could and could not stop the car from moving forward. the car proceeded to excellerate and when over a curb up onto pavement and through a metal fence and bent a 5 inch round metal fencing down to the ground and the car kept going another 30 feet till it finally stopped. you can see the skid marks in the the parking lot.

we flew to sea tac (seattle wa ) airport from slc ut. we planned on attending a family gathering and rented a car from hertz. we have owned a 2006 prius and asked if they might have a new model to rent for comparison on our part, which they did, however it turned out to be a prius c, which was not at all like our prius. the traffic on the freeway was stop and go slow on a multi lane freeway and were on an inner lane. ( i - 405 north bound ) as i rolled up to what might have been a stopping situation the traffic started to move forward, and as i stepped on the pedal to move forward, i noticed that nothing was happening and the car soon came to a complete stop. the car was absent and visible power, no visual information on the mph screen, the emergency light would not work, i was nervous and scared and everything had gone dark, i did not what to do, i tried to move the key position the cars behind me started to honk, and they were also trying to get around me, just as i was starting to call 911 for some help the car powered back up with a message to put the car in park and start the motor i moved out of the situation and got off the freeway and took backroads to reach the motel, with the intent to never drive this car again, the next am i called hertz and they made arrangements to trade the car out at our motel, which they did. the tow truck driver indicated that the problem on this specific car was caused by its software and he was aware of other drivers facing the same situation, but i should count my blessing that i was not involved in a major accident i do not think this car should ever be allowed on our roads just based on this experience. for your review and validation - hertz rental record [xxx] lic [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

2014 toyota prius. consumer writes in regards to push start ignition system. *tgw the consumer stated the vehicle belongs to his parents. he noticed the engine turned on by itself. he was able to open the door and noticed the power push button was lit which indicated the engine was on. the screen on the center console stated no key was detected. he pressed the power button to turn the engine off. the dealer informed the consumer, if he walked away from the vehicle without turning off the ignition, the vehicle would stay on. the engine turned on because the vehicle was in battery mode to replenish the battery power, when the system detects the battery charge has dropped below a certain level. *jb

Shortly after purchasing my 2014 toyota prius in june 2014, i started noticing a moldy smell coming from the air conditioner. the hotter outside it got, the worse the smell inside got. i took the car to the dealer to discuss the problem with them. they informed me that toyota says this is an "environmental issue" and can happen in new cars and is therefore not warrantied. the service manager installed a charcoal air filter in the cabin air filter and said that it would help eliminate the odor. it did not. in fact, the charcoal air filter reduced the air flow into the cabin which caused the ac to not cool. i had the service department replace the charcoal with an original air filter in september after complaining that the ac wasn't cool. the smell in the ac persists. it's not just a bit when the car is turned on. no matter what setting i put the ac on, it does not help (fresh air or recirc). when it rains or when it is really humid outside, the car smells like a swamp (even before it is turned on). there is also humidity inside the car when opening the door. i've asked multiple times to have the evaporator replaced because i fear that it is not draining and causing mold and mildew to form. breathing in the mold is a serious health concern and toyota will not agree to any kind of fix. i'm also having other various hvac problems such as continuously fogging windows and a draft from the drivers side door. the car does not hold heat and is very cold during the winter months. *tr

Point sources of light (i.e. brake lights, headlights, traffic lights, etc.) at night time and to a less visible extent in the day time are duplicated or triplicated at distances through the front windshield. as the light source is closer to the car, the ghosting effect diminishes. this problem does not occur when looking out the side windows or rear windshield, but only occurs through the front windshield. this prism effect induces nausea and is incredibly distracting while driving. *tr

I purchased a 2014 toyota prius on may 31, 2014. today 6/18/14 i found out there was a recall on this model vehicle. i called toyota and i was informed the recall service had not been performed. i called a local dealer (different from the one where i purchased the vehicle) and they informed me that when they pulled the vin, it showed stop sale in effect. i do not blame toyota as obviously if one dealer could see the stop sale so could the other. i think that there should be stricter regulations on dealerships to make sure these recalls are completed before the sale!! just like the gentleman that complained earlier i also purchased a brand new defective vehicle, how can this happen several months after the recall. !! now i have to take the time off to take it in to have the recall fixed. this is a major inconvenience, loss of use of vehicle and loss of time from work. i also want to know how to get compensated for the inconvenience and time, plus the fact they sold and i have been driving an unsafe vehicle. *tr

2014 toyota prius. consumer writes in regards to engine failure. *smd the consumer stated a brown colored alarm appeared on the dash, which flashed on then off, as the vehicle started to slow down. if he tried to accelerate, the light would come on, but no response to increase speed. he managed to pull over, and stopped the vehicle. after a few seconds, he tried to re-start the engine and was successful. the dealer was unable to duplicate, the problem the consumer experienced.
