My 2003 Camry had been great since the date of purchase. Only had 2 problems with the car, one minor the other was major. I have 25000 miles on the car, and both the front tires were bare. I was able to see all the treads from the tires. The major problem I got was my Camry caught on fire and melted the entire engine. I'd pulled up to the parking lot at work, and 20 minutes later, I was notified that my engine was on fire. Spoke with fire department and they said it looks like faulty/malfunction wire/cables. Not sure if Toyota knows of this, but now I'm left w/o a car until m insurance figures everything out. Toyota should be notify in case there was a defect in the 2003 models.
