general problems of the 2010 Toyota Prius - part 1

I own a 2010 Toyota Prius hybrid 4 door sedan. I am the second owner of the vehicle. I purchased it in 2018 from a used car dealer. The vehicle ran well up until 2022 where a “check hybrid warning would appear on the dashboard along with a yellow triangle and service engine light would come on and the vehicle accelerator would not respond and the car would have to glide to the side of the parkway. This problem would happen when the car speed is between 60-70mph. It is very dangerous to lose power on the highway because many times there is no where to pull over. In 2024 I changed the water pump because the fault code on the cars built in diagnostic code read error “p216b” which is the cars electrical water pump signal. I researched it on google and a lot of 2010 Prius owners are complaining of the same thing. Also the changed water pump from April 2024 died again in January 2025. It is very scary that the cars accelerator pedal goes unresponsive and all the fault lights come on. My vehicle has 155,000 miles runs great and my family loves the 40mpg it gets. However, this stalling problem is being ignored by Toyota and could lead to a fatal car accident if not recalled by the manufacturer. To conclude, I would like for your office to possibly conduct an investigation with the 2010 Toyota Prius hybrid for this ongoing problem that the company is ignoring. This is a serious issue and can possibly lead to a fatal accident. Thank you for hearing my complaint against Toyota.

The gas engine had internal destruction cylinder broke and car became unusable at 158k miles despite being a hybrid with al Toyota maintenance at al hendrickson Toyota of coconut creek, FL. This is unacceptable and demonstrate internal combustion engine failure that fortunately occurred near my house and not in the hiway. Please notify Toyota motor company because I had to buy a new car and we are seniors with limited budget. It is a severe safety concern.

The contact owns a 2010 Toyota Prius. The contact stated that while driving 60-65 mph, the vehicle lost motive power and went into limp mode. The coolant temperature and several unknown warning lights were illuminated, and the message "check hybrid system" was displayed. The contact pulled to the side of the road, where he disconnected and reconnected the battery in order to reset the hybrid system. The contact was able to drive to the residence; however, the failure recurred. The contact used an obd reader to retrieve diagnostic test code: p261b. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA campaign number: 18v684000 (hybrid propulsion system); however, the VIN was not included in the recall.  the manufacturer was not made aware of the failure. The failure mileage was approximately 148,469.

Car slows down to a stop when driving on the freeway. With no power to accelerate, it makes it hard to get to the side of the road to be towed. Been to the dealer twice to address the problem, and was told that if I don't pay $200, that there is nothing they can do. Then when I did pay the money for evaluation, they told me the problem could be one of several things that would start the never-ending process of repairs that will keep me paying until they solve it. I would think that with a $200 code reading, that the dealers software could narrow it down to the exact repair needed. I mentioned to the dealer about the jov update I had done earlier to the car, but dealer refuses to recognize that there is a recall on my vehicle, and that I needed to pay money(that I don't have) to do anything. My check hybrid system light and orange triangle comes on when the car dies.

I was driving home from work when all the warning light all came on at once. The car suddenly stopped accelerating and the “check hybrid system” was showing on my dash. I was lucky enough to be going down hill so I can make it to a shoulder to get off the road. Tried troubleshooting everything but to no avail and needed to get towed because the Prius would not move at all. Haven’t got the vehicle checked yet because the vehicle will not move and can only be moved if towed.

2010 Prius started up in the garage 3 hours after being shut down. I am certain the car was not still running while we unloaded groceries from hatchback and left the garage. * nothing was retrieved from the front seat so no accidental start could have occurred. * my son "heard it start" almost 3 hours after the vehicle had been shut off while in another room near the garage. * I heard nothing from the upstairs. * the Prius key fob was nowhere near the vicinity of the vehicle at the time it started nor was any person. In fact, both key fobs were upstairs and only the currently used 1 had a battery and was stored inside a tin so as to always know where it was. *Toyota executives were made aware of incident but essentially denied the Toyota could start without the key fob: "Toyota is not aware for any possible way for the vehicle to be started without the key. ".

Engine is taking in coolant problem.

Traveling at freeway speed just after midnight, the "check engine" light came on. Less than one minute later, the "check hybrid system" alert came on, with an exclamation mark inside of a yellow triangle symbol displayed. The vehicle instantly had no power when the accelerator was depressed. The vehicle coasted to a stop and would not shift into drive. The vehicle was towed to our home. Upon delivering the vehicle to our home, the tow driver used an emergency battery jump start device and the vehicle was able to shift into drive and be driven into the garage. The 12 volt battery was replaced the next day and the vehicle no longer exhibited any disfunction. This was an unexpected event with no warning that the 12 volt battery was in need of replacement. It could have resulted in a serious collision, if the freeway had been more congested, as the vehicle had been immediately driven 2 lanes over to the nearest exit, and came to a stop just after exiting, safely at the side of the road. This is a very dangerous safety condition that should have had some type of alert that the simple 12 volt battery system was in danger of failing, causing a catastrophic failure of the engine and power train. Or, the car should simply not be able to drive, if the 12 volt battery is that low, to ensure passenger and community safety. Prime example: Toyota Prius has a warning alert that the key fob battery is low. The warning gives you a couple of weeks to replace the battery, and repeatedly displays the warning whenever you power up the vehicle.

Last year on September 13, 2021 I purchase a used 2010 Toyota Prius ( vehicle VIN[xxx]) with 122414 miles on the odometer, I got my oil changed on October 29, 2021 so I can keep track of when my oil is due. My odometer reading on oil change was 123,268. I drove 2806 miles, when I woke up on December 08, 2021 with no oil in my engine. I thought that was very strange so after adding a quart of oil my husband got for me. I took the vehicle back to the shop ( good year tire & rubber company 1585- a island lane fleming island, FL 32003) I originally had my oil changed at, to have them check if there was some sort of leak. The odometer reading at that day/ service was 126,074. After a full inspection of the engine exterior componence, no leak was to be found. Then I decided to do some research only to find out that back in 2016 Toyota had a lawsuit against them for having manufacturer defects in the productions of engine between the years of 2006 - 2011. The manufacturer defect was the engine piston would eventually start having oil leaks into the engine causing engine excessive oil consumption. That same day I took my vehicle to the nearest Toyota dealership ( coggin Toyota at the avenues 11340 philips hwy jacksonville fl32256) for a engine oil consumption test to be serviced on my vehicle. This process takes place by filling oil to the full line marking it. . . Confirming there is no leaks. . . . Sealing everything and I was to return after driving 1200 miles ( odometer reading at service was 126,094). Upon returning the vehicle on December 30, 2021. . . My vehicle failed the engine oil consumption test because after driving 1221 miles my engine was low on oil by 1. 5 quart. This kind of engine oil consumption not only causes my engine to deuterate in time, but also my vehicle diminishes in value. After it was established that my vehicle engine consumes oil / failed the engine oil consumption test. Toyota advised me to get a new engine that would cost me $6987. 63 information redacted pursuant to the freedom of informati.

1. This 2010 Prius has a faulty design of the piston rings, which is allowing it to burn more than 1. 4 qts of engine oil. 2. Such high consumption of engine oil causing an environmental pollution. 3. Furthermore, I took it to the local Toyota dealer I. E. Maguire Toyota located in ithaca, NY, they never chose to diagnose it or repair it. 4. I reached out to the Toyota and the Toyota still isn’t helpful w. R. T this high consumption of engine oil.

My problem began when I pressed my brakes and instead it accelerated. I thought maybe my foot slipped and didn’t know what it meant. It happened again a few weeks later and then all of the dash lights went on that indicated that I had to have the big brake recall repair. Being that my car is past the 10 year warranty and past the extension for mileage, I had to pay out of pocket. This repair was done and upon receiving my car back, the gas mileage instantly began to drop. It went from averaging 42-48mpg in my town to 25-30mpg. I took it in the be looked at and they ensured me nothing was wrong with the car at all. The battery wasn’t holding charge on top of this and it wasn’t reading the same on the dash about the 0-100 current gas mileage you’re getting as you go (the lines scale thing) that goes up when you let off the gas, and I could feel a strange shift while I was driving so I took it in again. They told me this time it’d be $110 to diagnose even though it was the same issue that started after the brake system repair, so I left extremely upset. A few days later my cars steering went out while I was driving and the whole hybrid system died. The car now only works in power mode.

While driving at highway speed on interstate 87 in new york, the 2010 Toyota Prius suddenly lost power while multiple warning lights on the dashboard illuminated, along with a "check hybrid system" notification. The engine would operate but at significantly reduced power. I drove it to an independent garage to identify the diagnostic trouble codes, which included p0a94 and p324e, an inverter problem with the hybrid battery and a problem with the intelligent power module. The currently is currently awaiting a confirm diagnosis at a Toyota dealership in new jersey, but the problem is exactly what thousands of other 2010 - 2014 Prius owners have reported, yet Toyota has yet to issue a recall to replace the inverter.

My car's abs, traction, and brake lights are on. I took it to two shops and they both said my car was recalled and to have the dealership fix it. The recall is on the breaks. The brake pedal is also not fully working, there is an abnormal leak of brake fluid pressure. Both auto service places said to demand for the dealership to take car of this because there is a class action lawsuit going on for this car with this exact problem.

Bad rings in the motor. My dealer said he is seeing a lot of Prius's like this. He thinks Toyota will have a recall on the Prius soon. Camry and rav-4 has already been recalled for this reason. My Prius just started using a lot of oil @130,000. (1qt per 1200 miles) please enforce a recall for consumer protection.

Tl the contact owns a 2010 Toyota Prius. The contact stated that while depressing the brake pedal, the brake pedal was firm causing the braking distance to be extended. The vehicle was taken to Toyota of Lincoln park located at 1561 n fremont st, chicago, IL 60642 who diagnosed the vehicle and determined that the brake booster and master cylinder were defective and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 100,000. The VIN was not available.

Upon turning the vehicle on and starting to drive, the internal combustion engine then starts and experiences about 20 seconds of misfiring to the point the car is without smooth power. This happens at random. If the car was in the wrong situation when it happened it could cause an accident. The same thing will occasionally happen when parked after waiting for the engine to start.

I was driving on the hwy with 3 children when it cut off on me and my steering wheel was locked . I took it to four mechanics I saw the Toyota dealer and they told me that it was my battery and now I know that I have a recall on it . I have not driven my car in three months I'm also still paying payments on it . I also was told that it was my break. I bought a new brake booster and pay for the replacement and the problem was still hungry just.

The morning of 8/24/20, I attempted to start my car. A message appears, "check hybrid system". I found there had been a recall, in 2018, that involves a software issue. I had my 2010 Prius towed to kolar Toyota in hermantown minnesota, on, I believe 8/26/20. They gave me an estimate of $3200 to replace the inverter. I had read about the inverter failure being directly linked to software recall. They said they'd look in to it and later replied to me that, yes, the inverter would be included in the recall and repaired at no cost to me. They said they had ordered the part but my car would not be ready until 8/31/20, at the earliest. They said the part arrived and my car was in the process of being repaired. I contacted them and asked how things were going. The service manager, taylor, told me "for the first time ever we had two vehicles, of the same make but different years, in for the same repair". He went on to say, according to fedex tracking, the part had been shipped but tracking showed nothing else. I asked him if he was sure the tracking was for my part and not the part for the other vehicle. He told me he had no idea for which part the tracking was for. He then went on to tell me we would just have to "wait and see if the part shows up". He went on to say "it could take days or weeks or longer" before we know if the part was coming in. A few days later I called to see if any progress had been made and was told by taylor "the part has disappeared from tracking". I asked him if that meant it had been delivered and was possibly the part for the other vehicle. He basically replied he had no clue. He said we would just have to wait and see, once again. I've been calling every two or three days since then. Sometimes he returns my calls. Sometimes he doesn't. I don't know what to do at this point. My vehicle is a 2010 Toyota Prius.

I have �check the hybrid system �window on dashboard. Independent mechanic checked and told me that it has problems with inverter. Toyota has and had multiple recalls but they are doing some type of reprogramming which isn't helpful. It is expensive and common problem.

When the vehicle passed 100k miles, it start consuming oil excessively. Now it needs a quart every 200 miles. I found out from the net that this is a known problem that Toyota has not resolved.

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.

Tl-the contact owns a 2010toyota Prius. The contact stated that the while driving at 60 mph, the vehicle front wheel started to shake and the contact lost control of the wheel and was unable to control the steering of the vehicle. The contact crashed into anther vehicle causing the vehicle to hit a median head on. The airbags deployed. No injuries. A police report was filed. The vehicle was deemed totaled by triple-a who came out to the crash location. Towed the vehicle back to the contact resident which the contact is awaiting an investigation. No dealer was not contacted. The manufacturer was not made aware of the failure. The contact mentioned NHTSA campaign #18v684000 (hybrid propulsion system) as a possible solution to the failure. The failure mileage was approximately 120. 000. Ck.

A number of things have failed on this car. 1. The hybrid battery pack system shut down and warned that I needed to see a mechanic. My mechanic diagnosed that the hybrid invert was defective and causing the battery pack to fail. 2. When braking at both low and high speeds, the car increasingly struggles to come to a stop. When applying foot pressure, you can hear the pump winding - this occurs while at rest as well as when trying to slow the car down. There are times when applying the brake that the floor pedal will lock and cause the car to skid while barely reducing the speed of the car. I have had multiple near accident incidences as a result and put myself and others at risk. 3. The car ferociously vibrates every morning - discovered that the head gasket has failed prematurely and due to the car overcompensating for the failing hybrid battery that is being impacted by the failing hybrid inverter. All problems have been reproduced and diagnosed at independent service centers. Multiple codes, warning lights and messages have alerted me to engine and battery issues - all of which appeared after the various issues and failures.

The contact owns a 2010 Toyota Prius. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was no warning light illuminated. The vehicle was taken to the local dealer however, the vehicle was not diagnosed nor repaired. The manufacturer was contacted and informed of the failure. The approximate failure mileage was 220,000.

The contact owns a 2010 Toyota Prius. The contact stated that while operating the vehicle, the vehicle suddenly stalled without warning. The vehicle was towed to an independent mechanic who diagnosed that the engine had overheated and blown the head gasket. The engine was replaced, and the failure was remedied. The manufacturer and local dealer were notified of the failure. The failure mileage was 164,912,.

I have a 2010 Toyota Prius, it overheated and the red light or the warning temperature light never turned on, so now I the car has a cracked cylinder head, that means I have to replace the engine.

~tl the contact owns a 2010 Toyota Prius. While driving 35 mph, the vehicle shook. The contact coasted the vehicle over to the side of the road and powered off the engine. The vehicle was restarted, but the failure recurred. There was no warning indicator illuminated. The vehicle was towed to the contact's residence and later taken to an independent mechanic, but was not diagnosed or repaired. The contact received a recall notification for NHTSA campaign number: 18v684000 (hybrid propulsion system) and went to Toyota of downtown la (located at 1901 s figueroa st, los angeles, CA 90007, (213) 354-9999) without the vehicle. The contact was informed that the part was not available for the repair. The manufacturer was notified of the failure and did not assist. The approximate failure mileage was 97,400.

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.

Tl the contact owns a 2010 Toyota Prius. While driving various speeds for approximately 250 miles, the vehicle lost two quarts of oil. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 148,785.

The vehicle was in a parking lot. Upon starting the car, the dash displayed "check hybrid system" and the vehicle could not accelerate above 25 miles per hour.

While driving our 2010 Toyota Prius ii on the interstate we began noticing a burning smell. Then, the abs light illuminated on the dashboard. We pulled onto an off ramp and as we slowed the vehicle down smoke began coming from under the hood. We drove very slowly down the road and the smoke became more prevalent. We turned on a side street and my husband put the vehicle in park, got out, walked to the front, and noticed that the passenger front head lamp was melted and there was a flame. We quickly got our family out of the car (2 kids in carseats in the back). We moved away from the vehicle and the flames become larger and larger. We called 911 and the hood was engulfed in flames by the time the firefighters arrived. They were able to put the fire out quickly, so it did not spread into the front cabin or rear of the vehicle. We had not had any recent work done and the vehicle was fully operational until the time of the fire. We had not been experiencing any problems prior to this incident.

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.

My car completely shut down in traffic, engine, steering, transmission all quit and I was almost in a horrific accident as I could not control the car or get out of anyone's way. The check hybrid warning light was also on. It was towed and the garage said it was a software update that I was not made aware of that caused complete failure.

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?.
