Very strange problem with the car. In the heat, an error on the hybrid system came on, and along with it the engine check, after which there was an upward climb, the engine was trembling and knocking heavily, it did not want to go. I stopped, removed the terminal from the battery and continued driving in the evening, there was no error and the motor worked perfectly. There is no error in the evening, but it appears on a hot day (Check Engine and Check Hybrid), Prius 30 2009. Now I also want to add that the battery was reviewed quite recently, all cells are 4 ampere hours and higher. On the advice of the technician, I replaced the main battery relay block. Did not help. Also, the second air conditioning compressor on the car burned out a month after it was installed on the car.
