Combination meter intermittently not functioning. When turning the car on, sometimes the dash meter works, sometimes it's just black and continues the entire time the car is running. Then when trying to turn the car off, it will not turn off, which is a major safety concern. When this occurs, there are no dash lights at all to indicate fuel amount, odometer reading, door open signal, check engine, maintenance required and so on. The speed being driven is not showing either which is another major safety issue. Cruise control also does not function, the center touchscreen does not display hybrid motor information or mpg. The beeping when backing up does not function. Also the rear hatch will not open while car is running which is also a major safety issue in addition to all of the other functions not available. The odometer is not recording mileage during these times which makes it difficult to do proper maintenance that goes by mileage, such as oil changes.

While driving on the highway at 70 MPH, the following symptoms occurred on my 2005 toyota prius: (1) car would not accelerate, (2) engine light came on, (3) problem light came on, (4) battery went red, (5) car stalled and would not accelerate/drive any further. After turning off the car and restarting it, I was able to drive it back and the battery recharged itself to green. After taking it to the dealership and having this problem "fixed", the exact same situation happened two more times, again 6 months later and then 2 weeks after that. The second time I was driving again on the highway at 70 MPH, the third time I was driving at night at 40 MPH.

We were driving on the highway at night and suddenly, without warning, the engine stalled completely, the car died, and all of the warning lights came on, including a red triangle, check engine, brake, and some others. The prius lost power and I had to turn on the hazard lights and coast to the shoulder. We called the aaa towing service and 911 (as the shoulder was very narrow and we could not get out of the car). The officer and the tow truck driver checked for all possible driver errors, including gas, but did not find anything out of the ordinary (the gas gauge showed 5/8 full). The car was towed to the toyota dealership in sunnyvale who are working to determine the cause. This was a very dangerous situation as we were driving on a highway, with a child in the car, at highway speeds at night and the car suddenly died. It has left us shaken and we will be contacting toyota to see if they have a fix for this.

I was driving on the highway when my vehicle's check engine light came on. Shortly after I saw a large amount of smoke coming from the engine. I pulled over and shut off the car. Car smelled like burned plastic and smoke. I was worried that the car could catch on fire or blow up! I had the car towed to my nearest toyota dealership.toyota claimed that the three way coolant control valve had failed and the steam came from a ruptured line in the coolant system. The job cost me $422.32. I didn't mind paying the service but after careful research into the problem with the 3-way control valve on the prius I had learned that this is a wide spread problem.apparently the valve tends to stick causing no flow of the coolant fluid. I feel toyota should fix this problem before someone gets hurt either by getting burned from a ruptured line or the car catches on fire.

I drive a 2005 toyota prius. My car has 26,000 miles on it; which is very low mileages. While I was on the highway, my car`s lights on the dashboard starts to flash. The brake system warning light and buzzer comes on along with the ABS warning light and the malfunction indicator lamp. I had nowhere to pull aside. After two minutes the warning signs shut off so I kept driving. Five minutes later, all the warning lights come on so I decide to get off the highway to take it to the knoxville toyota dealer. As I`m exiting the highway, I immediately realized that I had no breaks (when I pressed the brake pedal with my foot it automatically touched the ground)! I remembered that my dad always told me that in case of a brake emergency to pump the paddle until the breaks work. I almost crashed into another car; the exit ramp was very steep. I was going about 50 miles per hr by then; luckily I managed to stop while I kept pumping my breaks. I took it to the dealer right away. They checked my car and replaced: pump assy. Water, super long life c, inverter coolant pump, sliding yoke, reflashed engine and hv ecu and shaft kit. Steeri. I found my case very dangerous and my life was at risk. Not only was my life at risk but as well as other individuals. I would hate for this to happen to someone else! It was scary and I felt like my life might have been over.

I am writing about an incident with my 2005 toyota prius. On july 20, 2009 as my wife was driving our prius the engine light went on. She immediately drove into the parking lot of a small business and stopped the car. We had it towed to a repair shop. The mechanics there diagnosed the problem. The inverter pump that supplies coolant to all the engine parts had malfunctioned. The mechanics told us that the toyota company was aware that this problem could occur on our 05 prius. If we had the car towed to a toyota dealer the defective inverter pump would be replaced with a more recent model free of charge. The next day we had the car towed to the dealership. They examined the car and verified that the problem was a defective inverter pump. Their codes as printed on their invoice number 524093 [21 july 2009] are "34352 pulled code poa93, sub code 346-inverter cooling system performance. Found tsb eg001-07 to correct this concern. Replaced inverter water pump as per stb." this catastrophic malfunction occurred without any prior warning. We have maintained the car with regular maintenance as per the schedule in the owners manual. We were very lucky that the malfunction occurred while we were in town. Since we live in new mexico the malfunction could have occurred out in one of our deserts or on one of our mountains. We are both 73 years of age and both cancer survivors. The last thing that we needed was to be stranded somewhere or to have the engine completely destroyed if we were not able to immediately stop the car. I do hope that toyota will be required to perform a recall on the prius models that have this type if inverter pump so that owners can continue to drive their cars safely.

I have an early 2005 prius which has "stalled" I.e. Lost al engine power on two occasions. I believe the "stalling" is intentionally designed into the software to protect the transmission. I think a design decision intended to protect the car is putting my life at risk. My early 2005 prius has "stalled" twice: once on the freeway at 80 MPH when I had to jam on the brakes (someone cut me off) and again on surface streets at 30 MPH when I floored it to accelerate suddenly. In each case the transmission's internal components would be under tremendous strain unless it disengaged. In each case all lights, headlights, indicators stayed on, the "check engine" light came on, the car continued coasting (as if put in neutral), and the car was unresponsive to the throttle and the gear shift. (in neither case did I hit the gear shift nor power button before the "stall"). In both cases I coasted to a safe spot (try crossing five lanes of 70+ MPH freeway traffic at night while coasting). Only after parking, turning off power, and restarting power would the car operate...at which point it operated fine. Dealer couldn't find anything wrong...in fact the second incident was two days after my 30,000 mile service! They apparently took no action regarding the concern I expressed to the service rep with respect to stalling...he assured me they would check for all available software updates, but corporate told me today there is at least one update (relating to the navigation system) which was not downloaded, so apparently the dealer is not responding to this life-threatening concern. I called corporate today to start a "case" and was told they are unaware that this is a recurrent issue. This despite discussions in the press and on hybridcars.com. I am contacting you in case I am killed or injured before toyota figures out that this is a serious and recurrent issue. The first incident was around january or february 2005, and the most recent was monday sept 19 2005.

2005 toyota prius, new nov. 2004, current mileage 11,100 miles, incident aug. 13, 2005, 9:10 pm. Driving for 30 minutes at a steady rate of 45 MPH on rte. 78, 11/12 tank of gas, no air conditioning or radio on. Auto hestitated. Dashboard symbols indicated problem: brake failure, check engine, hybrid system failure. Another symbol was on computer screen - car with line drawn vertically through it. Battery usage indicator was disappearing. This all occured within minute or less. Pulled into a noco gasoline station. Put car in park but couldn't get the power off that kept the dashboard lights, headlights, air conditioning, horn on. Couldn't restart my car. I could only put my car into nuetral or park. Auto towed to the closed toyota dealership. Dashboard lights remained on. Unable to start the car or to lock the door manually or with the keyless system. Sunday, checked the carand the dashboard lights were off but I still couldn't start the car or lock the doors. Monday, explained my problem to service manager. This is what was done: new battery installed. No reprogramming of the ecu because the computer memory was gone due to this failure. Manager did not seem to understand what I meant about reprogramming the computer although said received all service bulletins from toyota. Asked for a copy of the work order for my records but he said he had to still figure out hours and so would send me a copy at a later date. . He explained the replaced battery communicated with the hybrid system and was sure this was the cause of the power failure. I had hoped the ecu would have been reprogramed. It wasn't. Special service campaigns 40a or 40 d are unknown to me. My vehicle has shown no problems during the last five days. Can I get my computer reprogrammed? Is it necessary? Recall going to be issued? I'm not safe!
