My wife opened the tailgate and the right side lift support exploded. A person standing across the parking lot thought it sounded like a gun shot. Small metal pieces flew about the cargo area in the car. When my wife then tried to close the tailgate the lift support bent. She was then able to disconnect it and close the tailgate. I included a picture of the remaining left side support plus the broken right side and where it was mounted.

I was parked in my driveway and put my 2014 Toyota Prius in reverse to back up and park in front of my late husband’s workshop about 15 ft. away,on Oct. 10, 2022. The car sped up so fast I could not brake fast enough (no warning).It stopped when it hit the large door of the workshop, and damaged it and the back of my car, costing about $2,000 to the car. I contacted my insurance agent right away, and the person above him at the company the next day, as well as the service manager at the Toyota dealer where we bought the car at the end of 2014. I expect an increase in my premium from my insurance company. I’ll take it to Toyota when it’s done at the auto body shop, but I don’t expect any flaw to be found b/c that is what happened when I had the same kind of accident with this car in Jan., 2022, when I put the car in reverse to back down my long driveway, (which I’d done many times before),and it sped up so fast (SUA) that I couldn’t stop it (no warning). It hit a maple tree in my yard, and it cost about $12,000 to fix the back of my car. I was not injured in either accident, but this flawed accelerator could have caused serious injury to me or others, as it has in many documented accidents in the last 20 years. From the reports I’ve read since my accident last week, thousands of people have experienced similar or worse accidents from a Sudden Unintended Acceleration in their Toyota vehicle. Also, I read in an excellent well-researched and independent report that NHTSA has not researched the accelerator problem thoroughly and has remained noncommittal as to its possible flaws. Toyota wanted to take the “black box” from my Prius in 2022 after my accident, but I didn’t trust them to take it, and tried hard to find an independent engineering group with advanced degrees to study it and identify the flaw in it. I will try again to find such a group. The floor mat was NOT an issue at all—it’s the original one, stuck to the floor about 4” from the accelerator.

I was driving home from work on 10/14/22. The traffic was moving very slowly because there was a wreck ahead and emergency crews were on the scene. I was having to break often while moving at a slow speed. All of the sudden multiple dash warning lights came on the vehicle and the vehicle no longer responded to my breaking in a normal manner. I pulled off of the hwy and drove to my local dealership on a side road at a slower than normal speed. I told the dealership to check my car for the recall I remember getting in the mail a while back that mentioned the car trouble I was experiencing. I was told that the recall did not apply to me because my car was over 150,000 miles. The local dealership indicated they could not assist me with having Toyota honoring the recall past the specified mileage. I contacted the national Toyota number and was told the problem was included in a "customer support program" not an actual recall from Toyota and that Toyota would not pay to fix my vehicle since it was over 150,000 miles. I see that some people have filed a class action lawsuit against Toyota in this matter. I was told the Brake Booster needed to be replaced and also a break pump assembly would be required with an estimated cost of $2,500. The car is not safe to drive as it is right now. Toyota is aware of the problem and I guess put the "support program" in place to try and get around a forced government recall and also in turn put a cap on the mileage out of the reach of many vehicle owners. I would like the government to make Toyota actually recall the vehicles that have this problem and pay to fix my vehicle with this issue.

My car stalled while I was driving it on 2 separate occasions. It is a 2014 w less than 70K miles: 1/2022 Within seconds of 2 or more warning lights going on, the engine stalled. I was able to steer, brake and drive on the electric motor towards home. The electric motor drove another .5 mile before it also died, leaving me with no power steering or brakes. I was on a slight incline and coasted most of the way off road. The car was towed to our local dealer, which said the intake manifold had failed. Dealer replaced IM and related hoses and gaskets. 6/2022 I was driving on a busy interstate at high speed in the passing lane. The car started to lose power and decelerate. I maneuvered to the side of the road and UP! the on ramp. Made it to roadside business on remaining battery power.

Hi my name is [XXX]. Toyota headquarter case # [XXX] Incident day July 6, 2018 I had a big technical problem with my 2014 Toyota Prius V where it caught on fire because one of the valve lifters fell into the engine head and broke the engine block while driving. When that happened, the oil began to leak into the muffler and the engine and hybrid wiring immediately caught on fire. Many of my colleagues who also bought the same vehicle for Taxi business use in San Francisco all have a similar issue as mine. A few of theirs caught on fire, and a few others mentioned to me that the head gasket for their same Toyota vehicle blew out and each of them had to replace it at around 120,000 miles. I believe that’s why they don’t manufacture these same vehicles anymore because of the defectiveness in the engine. I opened a case with Toyota Manufacturer back in July 2018 and they sent a specialist to inspect the vehicle after the fire. He found the piece that fell inside the engine and that damaged the engine. The Toyota specialist admit to me that the engine of my 2014 Toyota vehicle is very defective and must be covered under warranty. My mechanic replaced the engine for me with a used one with 28,000 miles. This entire case was documented under my name with Toyota Motors Manufacture. I contacted the highway safety and I tried to file a claim against Toyota at the time, but I never got a follow up on my case after I left various messages. All they said was that they will investigate but never gave me any information regarding the engine fire situation or honor any warranty. I hope this incident will be investigated by your department and have this vehicle under recall. Thank you.
