In the past year I have had 2 occurrences of unintended acceleration. The first in February of 2016. I was exiting a parking ramp up hill and stepping on the accelerator. I was driving straight then turning to the left (90 degree turn). When I took my foot off the accelerator, the car continued to accelerate and I was unable to get it slowed/stopped for about ½ a block even though I was applying heavy brake pressure. The car was revving against the brake pressure. No damage or injuries occurred. I took the car to the dealership where I purchased it (purchase date 8/3/13). They checked the car over and found no apparent cause for the acceleration. I took the car home, and it drove normally until 11/26/16. On that date I was driving very slowly in a flat parking lot, and the car began accelerating without my pushing the gas pedal. I was driving straight and then turning to the right (90 degree. I got the car stopped in a few feet by pressing extremely hard on the brake. My car did not hit anything. Technicians from the dealership have not been able to find a cause and I have not been able to get past Toyota's customer service department to escalate the issue for more detailed diagnostics. I have attached the timeline of trying to get the car diagnosed and the issue escalated as well as why I don¿T think user error is a factor.

On Feb 19, 2016 I was driving my 2010 Prius. The sunroof exploded, without being hit by anything. It exploded upward. I called Toyota, but they said it was not their fault. I had to replace the glass. I have photographs.

While driving in boston, I attempted to beep the horn to warn a car that was cutting in front of me, but the horn did not work. Toyota diagnosed this as a bad clock spring in the steering wheel. The inability to use the horn is a safety issue. An online search seems to reveal that this is a common problem with multiple Toyota models.

In July, I was braking to a stop on a Suburban street but my brakes wouldn't allow me to come to a complete stop in time. It was raining. I finally came to a stop in the middle of the intersection, where I was hit on the drivers side by an oncoming car. Additionally, my side airbag (curtain) didn't deploy. I was traveling less than 15 mph at the time.

Intermittent failure of for door locking/unlocking mechanism. Apparently a fairly common occurrence in this make and model. Safety risk : inability to exit the vehicle in an emergency e.g. accident, fire, if the locks fail unexpectedly.

In Feb 2015 after owning the car for a few months, the sunroof exploded on the freeway at a speed of 60 mph. The break was directed up to the outside (not down as if something struck the window). The side windows were cracked so it was not an issue of the heat/cold change or too much cabin pressure. Now Aug 2016, the exact same thing happened again. This time Toyota is refusing to acknowledge there is an issue with the sunroof. In both instances, the sound was loud like a shotgun and extremely startling. Glass could have rained down on me or I could have been startled causing an accident. I do not understand how the sunroof can break twice in the same manner within 1 1/2 yrs owning the car. This seems like a dangerous issue and am concerned that it will happen again. I have pictures but am unable to load them. I also have a video camera in my car to show that there were no other cars near me at the time this happened.

  • 30,000 miles
A recall issued for an electronic component of my vehicle in February 2014. After searching the recall database by my VIN, I learned of the recall and made an appointment (March 8, 2014) to have my car serviced by the same dealership where I purchased it (North hollywood Toyota, 4606 lankershim blvd, North hollywood, ca 91602). When I went to pick up the vehicle, I was told by dealership employees that the recall did not apply to my car, and therefore no fix was made. The recall website shows that the recall remains to this day, and is marked incomplete. It is unacceptable (and dangerous) that I brought my car, with a known recall, to a Toyota dealership, and when I inquired about the recall, I was apparently lied to.

I along with an alarming amount of others have experienced the 2010 Prius begin to burn oil at an alarmingly high rate around 60-80K miles. This is accompanied with an emission into the cabin of noxious fumes during high oil burn rate (heavier acceleration) moments. We have all been told by the dealerships that this is "normal". this has led to burning over a quart of oil every 1000 miles, headaches from the fumes, and now I have found out there is substantial soot buildup in the engine resulting from the oil burning requiring very costly repairs. Toyota refuses to do anything to help or even acknowledge the costly issue.

Car would not drive, or reverse it shifts to neutral since first week I bought the car in Aug 2010. I bought a Toyota Prius III 2010 (from the dealership Toyota of kearney mesa in san diego) in 2010. The car from the beginning would shift back to neutral when I set it to drive or reverse. I bought the car and am the only owner). After I encounter this, within the week I took it to the dealership where I bought it (san diego kearny mesa) and they told me that it was not a problem. Yes, it was a problem and they refused to fix it. This has happen to my car from week 1. now 5 years later, today, the car would not engage in "D" or reverse. I tried at least for 10 minutes. I called a dealership now in seattle (since I take my car here for service) and I was told that they never heard about it. I searched online and I found that this problem/bug does happen. Today I could not set my car to drive or reverse for about 10-15 minutes. It's a safety issue. My steps: 1. depress power button (to turn on) 1.1. wait about 5-10 seconds 2. depress the break + engage in D (drive) or (R) reverse. 3. the car goes to "N" neutral and cannot be put in gear drive or reverse. 4. turn car off. Go back to step 1 until your car engages.

On May 30, 2015, our home burned to the ground. The firefighters are certain the cause of the fire was my 2010 Prius - they know the fire started in the rear of the garage, the only other item in that area was a bicycle. Arson, faulty wiring and accidents were ruled out. Investigations continue, but they have identified an arc between the battery and the relay switch. My homeowners insurance carrier (erie) is trying to decide whether they should expend the additional $1,500 to open the relay switch box to see if they can determine if the arc was the cause of the fire, or a result. From the video footage, it is obvious that the water being poured onto the garage increased the intensity of the fire, which was due to the magnesium battery. Thestarpress.com has all the video: www.thestarpress.com/videos/news/2015/06/03/28436619/ we were trapped in an upstairs bedroom for 40 minutes - and given up for dead before the 911 operators heard my labored breathing over the still-open phone line. A heroic firefighter threw himself through the wall of our second-story bedroom to rescue us. My husband was not breathing when he was removed from home, but we have both recovered. We had been out to dinner earlier in the evening, but the car had been parked in our garage for several hours. I have heard of many other Prius fires, and wanted to alert you to our experience.

I live in williamsburg, va. It was very humid in williamsburg this summer. The inside of the dashboard has fungus and mold growing in it. I understand that this is a problem with many 2010 priuses. Fungus and mold growing in the dashboard of the car is a major health hazard. I have contacted Toyota about this issue and they are not willing to fix it. The fungus and mold are present at all times. The dealer is quoting $2,000 as the cost to fix this defect in the 2010 Prius.

On February 27, 2015, our house burned in the middle of the night while we were asleep. The fire started in the near vicinity of the right front headlight of the 2010 Toyota Prius. The car had been serviced just before the fire on February 25, 2015 at the local Toyota dealership. The car was off at the time and the key was not in the car at the time of the fire. While we were sleeping, the car evidently caught fire spontaneously at approximately 2 a.M. while it was parked in the garage. The garage door was closed. By the time we woke up, the garage was fully engulfed in flames. We were able to escape the fire. However, our house was too severely damaged (fire, smoke and water) after the fire to be livable, and it is currently being rebuilt. Our family of four (husband, wife and two children, 15 and almost 11 years old) is currently living in a rental house. We lost all three of our cars (the other cars were a Dodge durango and a Honda Accord) and a majority of our possessions. Damages are estimated to be likely in excess of $500,000 including house, cars, damage to landscaping, personal property, furniture, clothing, etc. Our homeowner's insurance is seeking a subrogation claim against Toyota for the expenses incurred regarding our claim. The Prius is scheduled to have a deconstructive exam soon with multiple parties present and is currently being held as evidence.

The vehicle runs ok and a few minutes later the yellow triangle turns on, as well as the check engine light and the vehicle starts to lose power. After a few more minutes the red steering wheel light comes on along with the "check hybrid system" message and the rest of the lights and the vehicles loses all power and stops. It will normally turn back on but there was one occasion where it didn't and my husband had to push the car to a parking lot. I took the car in on the recall which should cover this but all they did was update the software and blame the issue on a car accident. I don't know if this is true as just purchased the vehicle but it sounds to me that they could have fixed the issue under the recall.

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.

Prius 4-cyl

  • 70,000 miles
On March 4th 2015 at 8:00 am, my wife was trying to change a parking spot into another about 50 feet away in the same church parking lot. She started the engine and the car was put on drive. Within a fraction of a second, the car accelerated beyond control. She could not steer or stop the car. The car jumped a curb, hit a light pool and landed on a grassy area. Tire marks reveal that the car experienced a sudden rush of acceleration beyond control ¿¿unintended acceleration.¿ my wife is still under doctor¿'s observation. The car front right; bumper, tire, fender, door, "a" pillar, and other parts were damaged. The car was towed to daytona Toyota and is still there since March 4th 2015. On March 6th 2015 a report was electronically filed with Toyota motor sales, U.S.a., Inc. On March 20th 2015, a "cdr" crash data retrieval was taken. The car has not been repaired. Even if the car is repairable, I would hesitate to drive it, let my wife drive it or with clear conscious sell it to any other human being. Please help us to mitigate the situation.

1 original recall did nothing concerning hitting a pothole and losing brakes for 20 +- feet..result..alway give yourself 20 extra feet and pray. 2 antilock on packed snow or ice results in total lost of brakes..result either drive into a snow bank or go through the red light and pray again. So I guess Toyota accepts the fact they choose to give you steering control to save yourself and hope you are not at a railroad crossing! there is no pulsating like other vehicles. 3 if you are stopped on ice /snow...without traction car does not rock..does not want to move... for study can a metal stud tire be made for priuses"?"would it help or sell car only in Florida..

The dash display mph and mileage totally went black. Looked it up on the internet and seems like it is a common problem for the 2010 Toyota Prius. Sounds like Toyota use to cover this before this year model, but not now, even though it is still happening. They may have done their dash alittle different, but it is still having the same problem.
