Check Engine Light On Problems of Toyota Prius - part 2

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.

2004 Toyota Prius died at 65 mph on I-395 carpool lanes. Multiple warning lights flashed on. Was able to coast it over and restart for a mile or two when it completely died again. Was towed to springfield va Toyota dealership were it was serviced. Error codes c2318 (low voltage error - power supply malfunction), battery code 8442 were reported. Also, check engine light on, found code p3791/engine won't start. Reprogrammed ecu dp0199. Cars shutting down in high speed traffic is a crash waiting to happen. We're not convinced that re-setting the engine code is enough to fix the problem. Has the original software problem been located and fixed? dealership couldn't give us that answer.

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.
