Well-maintained, dealer-serviced vehicle sputtered and stalled while driving on the freeway at highway speed. was fortunately able to coast to a stop on the shoulder, but vehicle would not restart. dealership identified the problem as a fuel pump failure, which occurred with no warning.
As i was driving 55-65 mph on the highway, the check hybrid system alert came on, and all of a sudden i lost power. i was able to make it home but going up hill it would not go faster than 35 mph, and 40-50 mph on flat ground. this happened on a busy highway where the average speed is 55-65 mph
I took my 2010 toyota prius to dealer ship for a software update, and now the hybrid system kept having problem, once i disconnect the 12v battery, the car will do fine for like a week, then the hybrid system will shut down, it didn't happen before the software update.
Car worked flawlessly and we maintained it regularly. took it in to address recall of jov update pwr mgmt ecu at dealer. dealer completed recall work. 2 days later engine lite check hybrid system and the ! on and triangle on. the car continued run but now was studdering when was not before the recall work. took it back to the dealer and he said we need a new hybrid battery. we believe the software update they did created a this issue. dealer acting ignorant and saying it needs new battery because of number of miles on car. asked for diagnostic print out from when they did recall work to they new diagnosis and they would not provide. we believe the recall update created a technical problem with our hybrid battery. we also believe that dealer not being honest regarding issues with this recall update and is using it as an opportunity to reduce liability for toyota on failed recall work and to use it as an opportunity to bring in large ticket sales repair ie they quoted us a new hybrid battery for 5,500.
I purchased a 2010 toyota prius, within a month i had to replace the fuel pump sensor (after it went out on the highway and the car died while driving it). then 6 weeks after purchase i was driving down the highway again and the hood ripped up completely shattering the windshield while driving. i later learned both safety's on the hood latch were broken and missing parts. it also has an oil leak that will cost me $2,200 to repair when i only paid $6,000 for the car on top of many other minor issues.
Tl* the contact owns a 2010 toyota prius. while driving 70 mph, the vehicle stalled and the "hyper" system failure warning indicator illuminated. the vehicle was towed to toyota of seattle (1925 airport way s, seattle, wa 98134, (206) 382-4300) where it was diagnosed that the egr valve and intake manifold needed to be repaired. the vehicle was repaired, but the failure recurred. the dealer stated that the fuel pump needed to be replaced. the fuel pump was repaired by an independent mechanic. the manufacturer was made aware of the failure. the failure mileage was 180,000.
Tl* the contact owns a 2010 toyota prius. while driving at an unknown speed, the vehicle stalled and the check pcs and check hybrid system warning indicators illuminated. the vehicle was taken to ourisman toyota chantilly (4135 auto park cir, chantilly, va 20151) where it was diagnosed that the battery needed to be replaced. the vehicle was repaired; however, the failure recurred. the vehicle was towed back to the dealer where it was diagnosed that the fuel pump needed to be repaired. the vehicle was not repaired. the approximate failure mileage was 127,735.
While driving on the highway, service engine light came on, and car began to lose speed -- only permitting travel at about 50 mph. within a few minutes, the car shut off entirely. fortunately, was able to get to side of road but this could have been extremely dangerous due to lack of warning, and fact that was driving on a highway where others are going 60-70mph or faster. the inverter overheated and needed to be replaced. this issue was part of a recall, but did not include my year/car. extremely upsetting that toyota does not recall it or at a minimum send a warning to owners to have this looked at. this can cause potentially fatal accidents, and toyota seems to be aware of the issue.
Recall notice eoe was performed on my 2010 prius to correct an invertor problem. a software update was performed. according to my dealer at capistrano toyota as well as other dealers this was just a bandaid and not a true fix. the owner of capistrano toyota as well as other toyota dealers have written to toyota that the invertor needs to be replaced. the dealer h,s had many cars come back after the software fix and had to have the invertor changed. if the invertor fails while driving, the car can possibly just stop running or slow down to 15 miles. this will be very dangerous and possibly deadly.
Vehicle has lost power on the freeway multiple times forcing me to pull over. in one instance i was almost rear ended by a semi. the vehicle will show a temperature warning and will then shut down and read, "check hybrid system". the toyota dealership claims it needs a new engine. this is a well known issue and will go in front of a judge in january. i have contacted toyota about this and they tell me it is out of warranty and not eligible for the warranty enhancement. this should have been an unlimited mileage recall but toyota refuses to do anything about it. this happened again this morning to my wife who was on a freeway where the speed limit is 70mph. this is an extremely dangerous error and i would hate to see someone die because their car stops on the freeway. this vehicle has also had severay p0401 codes, there is an warranty enhancement for this as well but limited to 150k miles. i was told by the toyota dealership it was also a culprit for a blown head gasket.
Leaving a parking lot driving at under 20 mph, 'check hybrid system' flashed with engine icon appearing; ambient temperature at 104 degrees. drove home and connected wifi elm 327 that displayed p0a080 dtc. failure mileage 152510 just outside 150k california emissions warranty but below 10 year warranty at 9 years and 2 days failing 07-16-18. drove to nearest toyota dealership 07-17-18 who diagnosed dtc p0a80 p0a3000 to battery blocks v06 12.67 volts, v07 13.91 volts. v05 14.14 volts, v09 14.18 volts, v10 14.18 volts. detail code 1 is 123. poor fuel mileage and oscillating charge discharge of hybrid battery pack began 02-09-2015 at 91,036 miles typically 42.7 mpg. toyota motor sales denied good will assistance request citing out of warranty case # 1807172401. remedy is replace hybrid battery pack at near $4k with core exchange.
On 05/12/2018, the vehicle was in motion, merging onto the freeway, when the check engine light came on and the message "check hybrid system" was displayed. the vehicle was not driveable at normal street speeds and had to be towed off the freeway onramp. the vehicle was towed to a toyota dealership on 05/16/2018, where the diagnostic found that the inverter needed to be replaced. the diagnostic did not find any other fault codes. the inverter was replaced under warranty. then, 3 weeks after the completed repair (less than 200 miles), on 06/11/2018, the vehicle was stationary and idling when the check engine light came on and the message "check hybrid system" was displayed. the vehicle was towed to the same toyota dealership, where the diagnostic found that the fault code was with the hybrid battery this time, when it previously had not been an issue. after the code was cleared, the vehicle was 100% driveable and taken home while we consulted options for alternative repair or diagnostics.
Brake actuator has failed. traction control, abs, brake lights illuminated on dash. more effort needed to engage brakes. this affects the regenerative braking as it no longer charges on braking as it was designed. checked toyota website for recalls since this is safety related, and there are none. which is quite disturbing. i've researched prius forums and this seems to be an ongoing problem. toyota issued a recall for the generation 2 model, however this seems to be a problem for generation 3 models as well. the problem did occur when on the highway traveling at 60 mph.
Toyota inverter failure. my specific vin wasn't included in the recall, but the ipm did fail, in the middle of the street, while driving, my car lost all power & went into limp home mode. fortunately the street wasn't busy & i wasn't struck by another vehicle as i had my 6 week old newborn in the car with me. i had dutifully checked to see if my car was involved in the recall & it wasn't, even though it failed. they only fix it after it fails, which is outrageous. someone is going to die when their prius loses all power while driving at highway speeds.
At about 125k miles, my prius nearly ran out of oil between services, and i religiously service my vehicle. i burned 1 to 2 quarts between services since. at 272,408 miles, i just paid $5751.59 for a complete engine rebuild... rest of car is in great shape. oil consumption problems were known by the dealerships, but i was given no recourse except dealing with it. latest issue..check engine light on, misfire on cylinders 1 and 4 (progressing to all), horrific knocking noise with sound of rushing water upon start-up. eventually, (once the cylinders fired significantly) the engine could run satisfactorily for the remainder of the drive... until the next start. early on i read that toyota knew of the under-engineered motor of the 2010s, but i have not received anything announcing a recall or care to fix their engineering issue. i have my service records to validate the care i've given to my car. the date of the engine rebuild is what i will provide as to when this happened, but the oil consumption began years ago.
I had a sudden loss of power with a popping sound. the failure nearly caused an accident because i was turning into a traffic lane. this left me stalled in that lane of traffic. the failure turned out to be the inverter over heating was caused by the cooling pump in the inverter failing, which caused the inverter to overheat. this was not covered by warranty and was a very expensive repair. i chose not to have the dealer repair it at their extreme prices. i paid the dealer to diagnose the problem. then i had greentec in olathe ks. repair the system at 1/2 the cost that the dealer wanted
Water leaking from engine cowel getting into ignition coils which is causing engine to shudder and stop sometimes too. seems to be a known toyota issue yet not being rectified by manufacturer. seals seem to allow water to get into the ignition coils hence the issue. vehicle is stationary when first observed then shuddering and misfiring occurring as vehicle is being driven also leading to loss of power as its being driven which is quite dangerous on highways.
Hybrid battery complete failure while driving. owned the cars 7 years since new.
In fall of 2015 recall for hybrid system failure was preformed to computer system. in the fall of 2016 i was pulling out onto traffic onto a state route when engine lost power and lights for the hybrid system came on. was running on only gas engine with limited slow acceleration to about 35 mph. was able to safely drive it to a location to park it until flat towed to the dealership. was told by toyota dealership that the hybrid system failed, upon research i found it failed exactly as stated in the recall that was done in fall of 2015. the previous recall "fix" was too little too late the damage had already been done. fought with toyota dealership and corporate about that this was a recall fix that failed and didn't fix the problem. they would not cover the cost of the $3000 repair entirely and i am stuck paying half of the repair that should have been covered entirely under the recall.
Oil consumption. i purchased my prius with 77000 miles for a local toyota dealership. my car now has 140000 miles and consumes 2-3 quarts of oil per week. i have contacted toyota customer service for help. i was directed to have an oil consumption test preformed. if there is a problem toyota may offer repair assistance however my engine is not on the list of toyota approved vehicles eligible for complementary repair. i am required to pay out of pocket for the test and repairs. i will update with results as soon as possible.
While accelerating on a highway going from the right lane to a left lane with my two young children in the car, i got a" check hybrid system" on the screen. which made the car unable to accelerate, all i could do was to put my hazards on and pull thru 3 lanes of high speed cars to get to a breakdown lane next to an on ramp, so i was in the middle of the 4 lane highway and 2 lane on ramp. i then got my kids out and ran across the on ramp to put them on the other side of the concrete barrier for protection. then i went back to the car to gather waters and food because it was 90 degrees out in utah, i waited on the side of the road for 30 minutes until a tow truck came. i am very very upset about this because it could've caused an accident and also put our lives at stake from possible re end.
48 mpg when purchased new in july 2009. 30 mpg at 130,000 miles in 2016. gumout and seafoam helped clean out fuel injectors with improved 35 mpg.
While in motion at 30 mph on a city street(bridge), all of the warning lights on the dashboard came on and the car slowed down to less than 20mph. i was able to drive the car at 20 to a repair shop. had this happened on a freeway with limited or no shoulder or while in the left lane, it could have resulted in a serious and deadly accident..since toyota failed to notify me of this problem, i took it to an independent repair shop and they diagnosed the problem as failure of the intelligent power module (ipm), part of the hybrid inverter. i then had the car towed to a toyota dealership where the repair was completed as part of the warranty enhancement program. i am including a pdf that shows the diagnosis performed by hawthorne auto as well as a copy of a letter from toyota that i never received. i cannot overstate the potential danger this defect could cause. a less experienced driver might have panicked. certainly, if this had happened on a freeway in rush hour traffic, i could easily have been rear ended - drivers generally and reasonably do not expect cars going 60 to slow down for no apparent reason to 20. toyota has determined that this problem merits only a "warranty enhancement" rather than a recall. i believe that they do not want to issue a recall because this is an expensive repair. i hope that nhtsa will take steps to make this a recall before some innocent person dies as a result of this serious defect. i have sent you the documentation that i felt would be sufficient for your investigation but i have more if you need it, including many pages that detail the results of the diagnostics performed by hawthorne auto. respectfully, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr
This happened twice. the first time i was driving 40mph, the check engine light came on and then the accelerator stopped working. then the check hybrid system light came on and i guided the car over to the side of the road. the car would start but the accelerator would not function and the (digital) speedometer numbers disappeared. i brought the car to the dealership where they replaced a valve and told me it was fixed. two days later (after driving the car without incident on several trips for at least 40 miles) the same exact thing happened, however this time i was travelling 50 mph while entering a very busy highway during rush hour.
I was driving approximately 35 mph and all of a sudden the car stalled and stated, "check hybrid system". stopped the car right away called my insurance company for emergency road service and had the car towed to a toyota facility where they diagnosed the problem as a failed inverter, which is part of the hybrid system. this is a safety issue and must be addressed. if i had been on a freeway or in heavy traffic, i could see this being a very dangerous scenario. *tr
Accelerated to get on highway. once on the highway the system hybrid warning light and other warning lights and audio alarms came on. we had to exit immediately because we lost the ability to maintain highway speed. *tr
The vehicle's fuel guage became stuck causing me to run out of fuel on a busy highway almost resulting in an accident. an attempt to refill the tank was only minimally successful in that only 3 gallons were accepted by the tank.
I am writing due to having had my 2010 toyota prius self accelerate while driving on four occasions. this began occurring after i took my vehicle to toyota of clermont, florida for a routine service on 3/31/2014. while the vehicle was there, the dealership also performed a recall on the vehicle. this recall is referenced as: tech(s) : 20799 recall eoe motor generator and power management update perform software update for mg ecu and power management ecu agg09a 0.7 as of 8/5/2014 my vehicle has had unintended acceleration on 4 occasions. in 3 of the 4 i know it has occurred as i released the brake. this release is confirmed by the fact that it is necessary to reapply the brake to stop the acceleration. the 4th occurrence may also have occurred after a brake release. i have attempted to resolve this problem via both my local toyota dealer and toyota customer experience center at 1 800 331-4331. i am being told the problem is operator error. i have done the research to see if this is even possible. for me to apply the brake and fuel simultaneously would be both extremely difficult and very obvious. additionally if this diagnosis were correct the vehicle would stop accelerating when the brake was released. in fact the vehicle accelerates when the brake is released not while the brake is depressed. *tr
After driving for a combined time of 4 hours in a 5 hour period, my wife left a store she visited off zebulon road and i-475 near macon ga. when attempting to re-enter southbound i-475 the car failed and would not accelerate. a few seconds after the drive system shut down and would not restart. the dash indicators said check hybrid power system. the car was towed to a dealer rogers toyota in macon ga, where it now is. the dealer says that the problem was the engine control module though the inverter is being replaced under an existing recall issued last week. it is not clear if the engine control module is covered by the recall. *tr
Toyota release a recall for 2010 to 2014 toyota prius. recall was made to affected prius models to rectify software in two of the prius's electronic control units, one for the motor/generator and the other controlling the hybrid system.i took my car to the dealer to have the recall done, here is where my problems started, i saw a drop on mpg from 52 to 44. i waited hoping it just needed to reset, so after driving more than 10,000 miles, mpg still did not come back. i had this car for more than a year and commute has been the same. other prius owner has raised the same concerns as noted in http://priuschat.com/threads/who-has-done-their-recall.137632/ i taken my car back and they can find anything wrong with and that 44mpg is ok. having a recall mess up with the performance and not bee told so is no good business .please help. *tr
On monday february 24th 2014 my 2010 toyota prius, hybrid inverter failed while i was driving and my car suddenly stopped on the road. i looked on the instrument panel and the check hybrid system was illuminated. the car would not start. i decided to call a toll truck company to take me to the nearest toyota dealer. once i arrived the service advisor informed me, the 2010 toyota prius has two active safety recalls. i was never notified. the two safety recalls are the hybrid inverter & brake booster pump assembly. today is thursday february 27th 2014 and the toyota dealer has failed to repair and return my car. the toyota dealer stated this is a safety recall, they need permission from toyota headquarters to approve parts. i pleaded with the toyota dealer to provide me with a vehicle, while i wait, they refused. *tr
Driving on the highway in albany, ny area, slowed down to go through tollbooth as i began to accelerate to continue on highway, check hybrid light came on and engine abruptly stopped. i was able to coast the car from left lane over to the breakdown lane. turned off car and was unable to restart. toyota dealership found that the power inverter had failed and needed to be replaced. error codes listed by dealer: p0a94 dc/dc converter performance. *tr
Tl* the contact owns a 2010 toyota prius. the contact stated that the fuel sensor unit malfunctioned and caused the vehicle to stall while driving 65 mph. the vehicle was towed to the dealer, who diagnosed the vehicle has having a faulty fuel sensor gauge. the dealer replaced the fuel sensor gauge. the failure mileage was 54,047.
I was driving with the flow of traffic (around 30 mph) on a main surface street in a middle lane of a multilane street when suddenly the engine stopped, and i was unable to make the engine respond. the car immediately began to slow down; i could not make it accelerate to keep in the flow of traffic. i managed to carefully drift over to the right and maneuver through an intersection and glide to a stop on the right side of the road. i turned off the engine and repeatedly tried to restart it to no avail. i called for towing service and had the car towed to my toyota dealer, where the service people said it was an "internal failure" and replaced the inverter assembly. what has terrified me is that i could have been on the freeway driving at least 60 mph, where the consequences would be devastating to me and others. i asked if toyota would be reporting this to the nhtsa, and they said that was an internal determination. i asked if this had happened before to others and did not receive a clear answer. *tr
While driving at ca. 20 mph a sudden jolt and clunk occurred and the car was stalled. various dashboard lights came on, and the dash displayed "check hybrid system." towed to a toyota dealer, the problem was stated to be a failed inverter-converter that needed to be replaced. *tr
Our 2010 prius suffered a near total power failure on 5/10/13 when the car suddenly and without any advanced warning, lost power decelerating from about 35 mph to about 4 mph in less than 5 seconds. every idiot light came on at once on the dash panel and a "hybrid system failure" notice came up on the alphanumeric display. luckily, i was on a city street and not the highway when this happened. i was able to get the car safely off to the side of the road and call for a tow. our prius has approx. 44000 miles on it, is regularly maintained at the dealer, not mistreated in any way and gave no advanced warning indication that there was anything wrong with the electrical/propulsion system. the car lost almost total power, limped about 50 feet past parked cars and just died at the curb after i put it in park. it would light up across the dash, but never start the engine. we have had this car about 36 months. as this is my wife's car, i am greatly worried about the safety of the car and having this problem happening again, especially to her at high speed, multi-lane highway driving. it has been repaired at a local toyota dealership. they installed a new 12v battery and eventually the main fix, a inverter/converter. the car now runs like day one. however, how do we trust this car in the future if it did not give any warning of imminent propulsion failure ? i am getting nowhere with toyota about their providing some kind of advanced warning to get the car onto the shoulder of the road and keep it running for about 1 - 5 minutes. thank you *tr
The incident occurred when i attempted to accelerate onto a two-lane highway. because of a slow and sharp u-turn which precedes the short on-ramp, i disabled the eco mode for better acceleration. when i pressed down on the gas, the car immediately emitted a loud sound, became unresponsive and was unable to gain additional speed. even so, there was no other option but to merge onto the roadway while doing no more than 30 mph. in the meantime, the instrument panel showed a "check hybrid system" message along with several warning lights. i managed to avoid oncoming traffic (from behind) and safely pulled onto the grass. attempts to restart the vehicle were unsuccessful with the previous message reappearing each time. the car required a tow to the nearest toyota dealer. i received a call from them the next business day, and they explained the cause to be a defective inverter based on the diagnostic code. fortunately, the repair will be covered under toyota's hybrid warranty. it remains to be seen and i am hopeful this repair will fully resolve the issue. *tr
While carefully parking my prius 2010 at a hospital it accelerated suddenly and crashed over the cement curb. i say carefully because my prius had done this before but not enough damage was done to file with insurance. there followed another accident and another accident. then this evening while driving into my carport my prius accelerated again. it threw my dog that was in the front seat to the floor but i was able to avoid car damage as i was going to stop. i was barely moving, that is i still had my foot on the accelerator,maybe i could say coasting, when this acceleration suddenly occurred. this was the same type acceleration that caused all the prior accidents. i have reported this to toyota... and now you. hopefully you will help me. my prius is in the carport. it has not been moved. however, it is my only transportation. my prius' latest happening, before the one just stated, the hybrid system quit working during rush hour traffic on the interstate near a busy intersection. this was repaired before toyota sent some one to investigate the prior accidents. if more information is needed just let me know. this prius also had a battery replaced shortly after it was purchased as a new vehicle. this prius has wheel rim scratches. *tr
