2003 Toyota Prius Owner Comments

problem #2

Prius 4-cyl

  • Automatic transmission

2003 Toyota Prius gas engine stalled, warning lights came on all over the screen, and it would only drive on "battery power." After stopping, I turned the car off but it would not re-start immediately. After a few tries and then waiting, the gas engine started when I turned the key. During the time it was running on battery, air conditioner was blowing hot air. After gas engine re-started, air conditioner blew cold air. Toyota service said they had never seen anything like what was on the screen they diagnosed and said it was the computer and ordered parts. They were also thinking the battery had something to do with it. 1. they may not have diagnosed my car correctly since they do not know about this recall, and may not fix it correctly (including putting grease on certain wires). And 2. that news reports in the U.S. say it is 2004 and 2005 priuses which are affected, so 2003 owners may not get letters to take their car in on this recall. This could result in people being killed. I want service dept to understand that Prius 2003 owners may not be notified because Toyota may not be aware that they also have the problem. They should inform Toyota they have a 2003 in for repair with same problem as 2004-2005 cars. I am concerned they may not do repairs on my car in accordance with what is specified on the recall even if I did not get a letter. This upsets me and it also scares me. I am sure Toyota would notify service & owners if they were aware it also affects 2003 Prius'. so I want you to make them aware of it and be sure they send the 2003 owners letters too.
