A few months ago i had the required software update to adjust the safety feature in the hybrid system in case of a failure. While driving on a side street on 3/1/19 i pressed the gas after being stopped, the car jerked, and the check hybrid system light came on. This was on railroad tracks but the car did drive on the gas engine a short distance to make it over the railroad tracks. I had the car towed to a toyota…

Went in to have the spark plugs and 2 coils(cylinders 1 & 2) started shaking, knocking and smoking at the time i picked it up. Check engine light is on and hasn't gone off. The mechanic i take the vehicle to says it is a problem with this model car, trying to determine this, since he stated it is now my head gasket that needs replacing.

Starting from a stop after engine shut-down, the car felt like it was going over rumble strips. This got worse over time until i realized that it was actually an engine mis-fire. The dealer traced the root cause to a leaking cylinder head gasket that is a common failure on high mileage 3rd generation prius cars. $4,000 repair. First car i've ever owned that cylinder head gaskets are routine maintenance items. Clear…

Excessive oil consumption of approximately 1 quart per 1,000 miles as of may 2019. Toyota agreed to do a oil consumption test in july 2017 but determined that 1 quart per 1,200 miles was within normal range. Consumption problem has gotten worse and will probably result in having the engine block replaced with a used one at a cost of approximately $5,000

It would use about 1 to 2 quarts between…

Prius started consuming oil around the 105,000 mile mark. Two months ago, i took it to the dealer and they had me come back after 1100 miles after my oil change. They said it was consuming oil because the piston rings were leaking. The lady tried to sell me a used engine for 3,000 or 5,000 dollars. I told her that is why i bought toyota because i didn't want to spend money after 100,000 miles. I have looked online…

In the event that the engine may cease if it runs out of oil. We previously have only had american vehicles, and were told that toyota is a much better product.. Well as of this past april, we had this brief light go on. It doesn't stay on very long and…

Found out the violent engine shaking and the mystery loss of coolant without any noticeable leaks is due to a leaking head gasket that his common to many owners. Car now runs rough and mileage is affected. Many other owners reporting the same issue http://priuschat.com/threads/new-service-bulletin-for-engine-knocking-at-startup-t-sb-0012-10.102200/page-40
