2014 Toyota Prius Engine Problems

“I was going down the highway at about 70 MPH when all the sudden the Prius lost power. The Prius dropped down to about 55 MPH. After a short period of time the power picked up. I got off the highway and took the back roads. It was a very hot day.”

“Headlights and cabin lights failed to turn off when remote lock was activated. Lights were then turned off manually. Five hours later, in the parking lot, the car was nearly completely dead. Last time it happened, we left it and it recharged itself. This time, it did not recharge itself; it was completely dead the next day. We had to have it towed to the dealership, who jumped it and let it sit overnight. They say it now has no problem.”

“Within the last six months, and about four times, I had experienced rough/high idling during hot days and after driving over 80 miles; using air conditioning. (I work over 70 miles from home.) I decided to take the car to the Toyota of redlands dealership on august 4, 2015, because the car was displaying the same conditions. While on the way to the dealership, and on the freeway, the car began to idle heavily. I merged to exit the freeway and while on the off ramp, stopped, the car completely shut off. The display read check hybrid engine. Stop park the car safely. …”

“While driving on the freeway at highway speeds a series of yellow triangles suddenly flashed on the dashboard along with some beeps. The engine then stalled and the gas pedal no longer responded to any inputs. Due to a combination of sheer luck and driver presence of mind the car was steered to the shoulder of the highway where it came to a halt. The experience of trying to control a car with a stalled engine and safely steer it to the shoulder in heavy traffic was terrifying to say the least. The car was taken straight to the dealer where it was left for service. …”

“Head gasket failure. No check, engine, light or warning. My car was very well maintained regularly. After research, I found this to be a very common problem. Yes it is available for inspection. Upon request. The problem was confirmed by chemical test, ignition vapors going into engine coolant. Other symptoms were misfiring on cylinder two and cylinder four. Severe engine knocking.”
