2 Engine And Engine Cooling problem

Failure Date: 01/31/2012

If the Prius engine does not start immediately when the computer tells it to, the computer stops trying to start it and leaves you with only the battery power. . . Very dangerous when this happens in fast traffic or on an on-ramp. It can be restarted if one pulls off the road and shuts off the car and restarts it. After numerous incidents and attempts to determine the reason for the occasional non-starts, it turned out that the air intake flap in the engine can get dirty and stick, which causes the engine to sometimes take several tries to restart. (this was initially misdiagnosed as a computer problem, however that was not the cause. ) besides making the flap cleaning part of maintenance, the computer should also be fixed so that it will attempt to restart the engine while the vehicle is being driven, since things could cause the engine to not start on the first try (such as sloshing from low gas. ) I don't know if this is still a problem on newer Priuses, however as more of them have high mileage, this can be expected to be more of a problem.

3 Engine And Engine Cooling problem

Failure Date: 09/20/2006

My friend was driving my 2001 Toyota Prius on the highway, going 65 mph. I was in the passenger seat. A warning symbol with the triangle/exclamation mark appeared on my screen. The engine immediately died. We tried to get off of the road. Mack trucks were swerving into the exit lanes to get out of the way. <p> we were able to pull off onto the shoulder. This is extremely dangerous for me, my passengers and other drivers on the highway. <p> your agency has investigated this exact problem, which led to a recall by Toyota. Toyota blamed the problem on a "software glitch. " the problem is goes much deeper than a ã‚software glitchã‚쳜 -ã‚ it remains unresolved. I had my car serviced for this ã‚software glitchã‚쳜 recall (engine's computer (ecm) replaced and circuit open relay checked), but the problem still persists. The engine still cuts out at high speeds. My car has had this exact problem before and after getting it serviced based on the recall on three separate occasions. This life and death defect needs a better solution than simply attributing it to a "software glitch. ".

6 Engine And Engine Cooling problem

Failure Date: 08/02/2003

Twice now I have had warning lights appear on my 2001 Toyota Prius screen. The first time was three weeks ago while I was driving on a freeway in hot weather. I pulled over as I was losing power. The gas engine would not turn on. I was on battery power only. I limped to an exit and parked the car. I had the car towed to the nearest Toyota dealer. He fixed a steering recall part and thought it might be the problem. He could find no error codes. I drove off. Yesterday it happened again under the same conditions. I pulled over, waited twenty minutes and started the car again. The warning lights were then off and the power was now normal. I immediately took it to my home dealer. He tested it and today told me that he could find nothing. He said that if he could not recreate the problem in the shop, there was nothing he could do. There is no question that this is a significant safety hazard as the loss of power particularly during an acceleration onto a freeway could cause a major accident. My family will now not drive the car on a freeway.
