Check Engine Light On problems of the 2005 Toyota Prius

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.

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 was driving my Toyota Prius on the freeway and the vehicle died at 55 mph. The engine light illuminated and there was no power to the accelerator. Fortunately, traffic was light and I was able to coast to a secure spot on the side of the road. This happened on the approach to the bay bridge, which would have been a potential disaster had it died on the bridge itself. The car did not start again on my first attempt, but it did start 5 minutes later. I took the car to the Toyota dealer and they said they installed new information into the computer. I want to know why, if they know it needs new information, did I not receive a letter asking me to come in for service? this could have been really disastrous, and I fear that it will be for someone else.

Driving 65 mph on the freeway, the low-fuel indicator light started blinking. Approximately 15 miles later, still driving 65 mph, the engine shut off. Dashboard warning light and check engine light illuminated. "consumption" was highlighted in red. The car continued to drive in electric mode at 52 mph for about 1. 5 miles. When the battery was drained, the car came to a stop. After 5 minutes, I hit the power button to turn off the car, then again to turn on the car. The engine started and we drove to the next gas station, 4 miles away. Toyota (1-800-331-4331) said to take it to the dealer. The Toyota dealer said there is nothing they can do and Toyota has not advised them on a remedy. Dealer refused to provide me with this agency's name (NHTSA). I left a message with "the Prius team" at Toyota 3 days ago and they have not returned my call.

I purchased a 2005 Prius in January 2005. At the time of the incident it had about 8500 miles on it. It had been performing well and I had been getting excellent gas mileage and the internal mileage indicators has proven to be very accurate. While driving on SC highway 31 at about 60-65 miles per hour the gasoline engine quit slowing me to about 40 miles per hour. The dashboard lit up with with warning signals including the red triangle, check engine, vsc, breaking system and I don't remember what else. A few miles before this happened, my fuel indicator started to blink, but was sure that the problem could not be gas since I have often gone many miles before finding gas in similar situation and knew from past experience, my milege,and fuel usage indicator that I had about two gallons left in the vehicle. This was an unfamiliar road to me so I continued to travel using the battery hoping that an exit would appear. The battery quickly became so depleted that I pulled to the side of the road. I tried to turn the vehicle off and found it unresponsive. After a few tries it did power down. I called aaa for assistance. During my wait, I was able to restart the engine, but it again failed within a couple of miles, but I was able to reach an exit and pull off. After the second failure, I tried to restart again and this time only got the red triangle and check engine light. Aaa did add gasoline to the car, but the fuel indicator continued to blink and the bar never rose. The car was towed to sparks Toyota in myrtle beach, SC who called to say that they believe that the problem is low fuel. I do not believe that it the case as this had not happened before when the low fuel indicator came on.

I have a 2005 Toyota Prius, purchased new in oct 2004. I was driving on I-57 in illinois at 65 mph. Temperature outside was 91ã‚âºf. Low fuel warning signal began to flash. Since I planned to gas up about 25 miles away, I continued driving. Should have had approximately 2 gallons of fuel left. About 5 minutes later at 65 mph, the engine suddenly stopped running. The "red triangle of death" and the yellow "check engine" warning lights came on. Realized that the electric motor drive system was still working. Noticed that I was approximately 1. 5 miles from an exit. Slowed to about 45 mph and continued to drive using the Prius' batteries and electric motors. Pulled into a shell station and turned the car off. Began to refuel. After about 4 gallons, the pump clicked off. Tried again - it clicked off. Tried again and was able to refuel normally. In all, I added 9. 767 gallons. If the car has 11. 9 gallon tank, there should have been 2. 1 gallons left when the engine shut off. Upon restart, same engine warning lights were on, but within a few seconds they went off. Digital fuel gauge increased, one block at a time, until it indicated full. Car seemed to be operating normally. Resumed 65 mph. Car has continued to operate normally since. The shutting off of the engine was abrupt and would have been a safety problem had someone been following me too closely, or if I had needed full power to avoid traffic or an obstacle. Had read about this happening to other Prius owners and that some had reported not being able to restart the car. For that reason, I chose not to pull off on the shoulder and stop the car (for fear that I would not be able to restart it), and was fortunate to be able to drive with the electric motors to a nearby exit. Have not yet taken the car to the dealer to have the problem corrected. Have not had any parts replaced or software upgraded. Would appreciate any advice or service information you may know of.

Bought a 2005 Toyota Prius on 5/16/05. On the second day it lost power on the highway at 60+mph. Engine light and ! light on. Car ran well enough to take to dealer after re-starting a few times. Lights remained on until re-started at dealer. Car remains at dealer.

Without warning the check engine light keeps coming on. Consumer has taken car to dealer four times for the same problem. Dealer replaced different parts and the problem was there after three attempts to fix it. Consumer just got vehicle back for the fourth time. Manufacturer will be called today. Consumer was told they have never seen this problem in any other car.

Reported incident to Toyota customer support -- incident: 050412-000111 responses received from Toyota was that the computer was fixed based on a technical service bulletin. No recurrence since the fix. Toyota customer support sir or madam: I bought my 2005 Prius new from mechanicsville Toyota on December 1, 2004 and generally was quite satisfied with the car and the great gas mileage it provides. However, last Thursday, 4/7/05, with 4738 miles on the odometer, while driving home from work, all the lights on the dash went on including the master warning light, check engine light, vsc light, and the multi information display is showing the red hybrid system warning light. The car lost power and I had to limp it home. The energy consumption display for the battery pack showed one red bar and the fuel gauge had two bars left. I called Toyota roadside assistance which promptly dispatched a tow truck and delivered the car to the dealer. The dealer did a diagnostic test the following morning, Friday, 4/8/05, and could not find anything wrong. The only explanation I got was that this is a known isssue with 2 bars of fuel left and the cause was that the engine sucked in air with stops or turns. Is there a further explanation or fix for this problem? I feel that this is a safety issue. I cross railroad tracks to and from work daily and definitely will not want this car to stall on the tracks or anywhere on the road. My wife and I are a multiple Toyota owners: 95 camry wagon and 93 previa. I used to own an 83 tercel and my wife and step daughter have and still own a 96 tercel. These cars have been extremely reliable so that my experience with the Prius comes as a shock. I look forward to hearing from you on this safety issue.

With approximately 7100 miles on my car on Friday March 25, 2005 I was driving on local roads between 20 to 40 miles per hour when the car began bucking very badly . . Shortly thereafter the check engine light turned on. Worried that the vehicle may completely stall and quit on the open road I returned home and called my local arlington Toyota dealer. I brought the car in the following morning (Saturday March 26,2005) to check out the problem. They had the car all day and still could not identify why the car was stalling. Since I was schedule to be away the following week (trip to las vegas). I gave permission for techs to keep car all week if necessary. On Monday of the following week, I recieved a call from tech at my hotel that they had fixed the problem. He claimed it was a misfire in #1 cyclinder. So they replaced spark plug #1. However, he also told me not get the car engine wet. He warned that if I ever returned the car with a wet engine again that my warranty would be voided. I told him that I never open the engine compartment and that I would never intentionally put water directly on the engine. Particullary on such a sophisticated car such as a hybrid. In the past 10,000 miles that I have owned the vehicle I have taken it through the car wash a total of three times. I picked up the car upon my return from las vegas on Friday April 1,2005. I am happy to report that the car has been running fine ever since. However, since the recent rash of news reports of complaints filed around the country of the Prius stalling I am wondering if the tech at arlington Toyota had misdiagnosed the problem I experience this past March.
