Loud Engine Noise Problems of Toyota Prius

I previously sent in a complaint but there have been developments and I needed to explain more clearly. Our Toyota has less than 18,000 miles and has been very well taken care of. Despite this, our vehicle has not been in operation since earlier this month. It started by flashing warning lights 2 weeks ago and then wouldn't start up. Saturday when I opened the driver door to get something out of the inoperable vehicle, this initiated a very lengthy terrible sound coming from under hood on driver's side. It sounded like something would explode under the hood. This horrible process appearantly drained the whole battery. It has absolutely no signs of life now. All of this happened while the vehicle was stationary.

We noticed the red triangle light and so we checked the engine oil. The dip stick was dry. I put oil in the engine and the red triangle went away. I kept an eye on the oil level occasionally I needed to put more oil in the engine. 3 months after taking the car for a regular oil change at the Toyota dealer the red triangle came up again and this time I spoke to the dealership about the issue. The response was that it would be expensive to repair the car and the best solution was to buy a new car. I was never told about the 2011 TSB for excess oil consumption that Toyota had issued. Today, July 17th, 2020,I called the dealer to ask about the TSB, and I was told that the TSB has been out for 10 years so I had had until 2017 to qualify. I do not believe I ever received a letter notifying me about the issue. Had I received the notification I would been the first person in line at the dealership. Also, my steering wheel feels like it is loose, if the speed is over 45 mph it feels unsafe, the slippery sensor light comes on when I am turning the wheel slightly on a dry road, and there is an excessive noise inside the car even with the windows closed. This happens during highway driving. I am about to donate the car so that it can be used for parts. I love the car now I know to check with NHTSA when I purchase my next car.

When comes to a stop and on acceleration vehicle won't move especially after rain and car wash. It happened 10 times since June 2017 and once a week lately. Every time it starts with loud noise from engine,right after that the battery bar dropped from full bar to one bar quickly in one second. If I have to stop at the traffic light when this happens it won't move. Early this year 01/12/2018,it 's being towed to puente hills Toyota dealer and service couldn't find any clue after 5hrs. On 06/01/2018 we brought it in again for same issues to the same dealer and being told no clue after 5 hrs again . On 06/06/2018 at 18. 38 pm pst, it happened again. . I feel so unsafe to drive, it might get me killed anytime when it happens,.

The contact owns a 2008 Toyota Prius. The contact stated that while driving at 35 mph, there was an abnormal noise coming from the front passengers side. The vehicle was taken to an independent mechanic, who diagnosed that the engine mount became loose and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 115,000.

On this date while driving on the interstate 5 near los angeles my Prius made a loud noise and started shutting down as I was driving on the far left lane. The car immediately slowed down and the vsc icon as well as the check engine light icon became visible, however the odometer was blank and I could not tell what speed I was traveling, the car was coming to a complete stop. Once I managed to get to the far right shoulder the car made a stop. I was almost rear ended by a big rig which had to swerve to the left side in order to avoid hitting my car. It wasn't until then that I noticed the red engine light icon displayed on the control panel not the odometer. I have never seen this warning light but after looking at the owner's manual it clearly stated that once this light appears you need to get the vehicle off the road as soon as possible or it will cause an accident. This was the first time I noticed this sign and it appeared after the fact. The car had no engine oil, which was ridiculous since I had not noticed any leaks and I take my car in every 2 months to the dealer for an oil change. The dealer had no explanation other than it did not have any leaks and they were not able to verify when the red engine oil came on. This happened on 5/30/14, my last visit to the dealer was on 4/12/14 and at the time they did not detect any problems with the oil leaking. This clearly makes no sense and they are refusing to take responsibility. Toyota owners should be very cautious as this should have never happened the sensor should have given me a warning prior to the car shutting down. This could have caused many fatalities being in a heavily populated highway.

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.

The car was not used for about 4 days or so. When I started it, it exhibited a "rough engine start" for the first time. This happened when the gas engine initiated and lasted for about 10 seconds. During this time the engine made a very loud noise as if the car was chocking and engine wanted to get out of the car's hood. This has happened only once. The car stopped making the noise after 10seconds or so.
