I took my vehicle to my mechanic at my independent service center because I experienced shaking/significant vibrating at 60 mph. I had also experienced a loud noise that only lasted about 2 miles. He found that the right rear brake unit, specifically the caliper, had seized. I contacted Toyota of America because there was no brake warning light to alert us of this situation. I received a call back from David from Sloane Toyota in Glenside, PA, who confirmed that the caliper seizing would not cause the brake warning light to appear. He also indicated that the caliper is not something that is routinely checked as part of state inspection, or the regular maintenance schedule. I am deeply concerned that this mechanical failure of the brake unit could have resulted in death(s). I request that Toyota vehicle owners and mechanics be alerted to this, specifically the fact that the brake warning light does not alert a driver of this brake part failure. Further, I request that an inspection of the calipers be included in the routine maintenance schedule and annual state inspection. Thank you for the work that you do to keep us safe!

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

While driving on highway the vehicle loses power causing it to locse speed quickly. This is extremely dangerous if you are in an area where it is hard to pull off. It will drive 42mph until the battery dies. This is more common than most issues with this model. Please make toyota replace the engines in these vehicles. "check hybrid system"

Excessive oil consumption LED to engine failure and replacement cost of approximately $5000.00 also excessive oil cost to constantly fill oil over the years. I purchased the vehicle new. And got stuck with it as I was going through divorce and not working it was unfortunately cheaper to pay for a used engine replacement through toyota. I have saved all receipts in hopes of recuperating money in the future

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.

I was aware the check engine light and alarm came on when I would make right or left hand turns. Took my vehicle in for a check. Was told there "was no oil on the dipstick" so had my oil changed on 2/21/2018 and my mileage was 72704. They did an oil consumption test at this time. When I returned at 73696 miles to have phase two of the test checked, the oil was at "full level". Now at 77,250 miles and am having to add oil again. Stopped at toyota service on 6/01/2018 for them to check the warning light. Vehicle was low on oil again. They topped off the oil at no charge. Thank you! When asked what else could be done about this problem, I was told I could replace the engine. Not going to happen with my 2010 prius. Not due for an oil change for quite some time. Guess I will check and add oil as needed in the interim.
