I am the owner of a 2004 prius. After buying my car used 2 years ago I noticed that once in awhile the display, including fuel consumption, speedometer, odometer, and more, would not light up and that the car would not turn off easily several times I have been in situations where I have little gas an am unable to see my gas gauge or know how fat iam going on the highway. I understand that this was once covered by toyota under the warranty extension but is not considered a safety concern. The warranty extension is expired. In what universe are a functioning fuel gauge and speedometer not considered a safety concern? I am also concerned that this will deteriorate further and cause an accident.

This occurred to me yesterday while traveling 60 MPH in 94 f heat on I-76 e just before the 676 / 76 split. I was traveling in the far left lane when the car suddenly lost power. Looking at the dash I noticed the shifter had moved itself into n (neutral), it would not move back into drive. I applied my hazard lights and began forced my way rightward across three lanes to the shoulder, speed rapidly decreasing and seemingly more sluggishly than a normal coast. I think the emergency brake was automatically being applied or I was fighting a braking system. One lane from the shoulder, a ups truck was headed for me from behind. Luckily, he was able to swerve into the shoulder and pass me there as he could not move left into other traffic. We only narrowly avoided a collision with me or the elevated barrier on the side of the road. I had only 10 MPH left and no ability to redirect my vehicle. Once on the side of the expressway, I was able to google this well-known issue with the vehicle. I let the vehicle cool off, turned off the air conditioning, though didn't want to risk turning the vehicle off. I was concerned I would have to wait until nightfall to get back into traffic (still flowing around 60 MPH and a very narrow shoulder) luckily during a small traffic backup up the road I was able to re-enter traffic at a modest speed. I crossed my fingers as the rest of my commute (another 2 miles or so) was 95% highway driving. Luckily the car held out for me to get home.

2004 toyota prius accelerates due to gas pedal getting stuck in the floor mat. This morning I was driving my toyota prius 2004 that I bought from the original owner who mentioned all recall issues were addressed by toyota dealership. He mentioned the dealer shaved off the gas pedal to make it shorter. But today, while on I 495 going eastwards just before entering the hov lane, I pressed the gas pedal all the way down to over take another slow vehicle. The car engine kept raising noise, and car started to accelerate on its own. I braked, the car slowed a bit but engine kept running fast... I realized this is potentially same issue that people reported on press and with lot of struggle trying to brake and slow down, realized and put the car into n, neutral position. I am lucky to know this from media reports, otherwise I would have been another dead guy on a prius! While I was still on highway, needing to maintain speed I put the car back on drive mode, d and the problem continued. I realized, I can lift the gas pedal with my left foot, and succeeded in untangling the pedal from the floor mat. After I did that it was fine. I arrived at work, but with extreme shock and disappointment. I am wondering how this problem can still remain after a recall repair is done on this vehicle. This is completely unacceptable and my life was in total risk and I survived today purely because of my technical skills and knowledge about this car issue. I am an engineer in profession, a mechanical engineer with a masters degree and I understood how to react. If it was for my other family members in this situation the outcome would have been totally different. I am very very disappointed with toyota corporation and also with you, the federal safety agency for not making sure that all prius out there are safety compliant. This is really terrible ! ...because its a known issue, and old issue that should have been corrected.

The fuel tank can not be filled up without spilling large amount of gas, which is a great fire hazard. It seems that the fuel tank gets too much air inside when filling up and the air pushes the gas gashing out.

Tl* the contact owns a 2004 toyota prius. While driving between 40-45 MPH the gasoline motor would fail, and then cause the vehicle to stall without warning.

Updated 01/12/10 *bf all of the alarm lights on the dashboard had illuminated when accelerating. When the consumer stopped the vehicle and switched to park, he was unable to shift the vehicle into neutral. After about 15 minutes, the consumer was able to shift to neutral.

Dt:two weeks ago, the consumer was driving her 2004 toyota prius at 50 MPH and it died. Luckily it was not during rush hour traffic and occurred near an exit ramp. The consumer was able to maneuver to an exit ramp where she coasted downhill into an off street. The vehicle was towed to a dealer and they have had it for 2 weeks now and they stated the inverter that ties the hybrid to the gas system was the problem. The consumer feel this is a design flaw and feels that she should have been notified by toyota of this problem. *jb
