2003 Toyota Prius Owner Comments

Prius 4-cyl

  • 115,000 miles


My 2003 Prius (first gen, from Japan), has been thru a few recalls - 1 was to seal the battery better early on (04ish), then it was given new pinion shaft nuts. Latest issue has been an issue all along, just not diagnosed/fixed til now. Sometimes the 'check engine' light would come on, with the car/! /triangle graphic on touch screen. This time it didn't go away. Long story short, it was the electric water pump that needed to be replaced. Dealer said it wasn't cycling properly, leaking antifreeze; also a big hybrid battery issue was showing up, but they suspected when fixing water pump it might clear up battery issue. Did research, found this has been a big issue for a lot of Prius owners. Saw the consumer reports & this story, from a Toyota news release. The following is exactly what I've experienced, & my car was part of the pinion shaft nuts/steering column recall, but not water pump recall!: "Toyota is recalling 670,000 of their popular Prius hybrids in the us to correct two safety issues. They say all of the vehicles will be inspected to see if a part in the steering shaft needs to be replaced due to an issue that could cause excessive wear. 350,000 of these same Prius vehicles (from 2001-2010 in Japan ) are also being recalled to replace the electric water pump for the hybrid system. Toyota says the pump could fail and cause the hybrid system to stop running. They said its dealers will inspect & replace any defects free of charge. Recall notices will go to owners in Dec. 2012. About 2.77M vehicles worldwide are affected."Toyota did not pay for my repair, $669; that was with a 15% off coupon! I am keeping my receipt. Toyota needs to include my VIN in the next batch of recalls for this defective water pump, which has been defective since day 1, but a slow diagnosis, that may have affected the overall function of the hybrid system battery permanently. No fun!

Toyota consumer safety advisory potential floor mat interference with accelerator pedal. I've had issues with the floor mats in my 2003 Prius almost from the beginning of owning my car. When I looked at the illustrations on the Toyota web site it was clear that the retaining mechanism it identical to that of the 2004 Prius. Yet the model is not being covered by the recall. Please consider expanding the recall to all affected models and model years.
