I have a 1999 Toyota Camry V6 with 34,000 miles and I am finding that all information about this being such a good car is not true. After reading some of the problems listed just on this
posting I am considering getting rid of this car. When I first bought this car it evidentially was out of alignment and I ended up buying new tires, the original tires were worn to the metal.
And it happened again and had to buy new tires again.

Several months ago, I took my car in for regular oil check and etc. They found some kind of fluid had been leaking and that oil change cost me $2,000..00. A month later the car would not start, called the Toyota people and I had to get the car to them. They said it needed a new battery. So $154.00 later by about two weeks, went to start the car and it would not start,. then it started. One night this week coming out of a restaurant from having dinner went to start the car and it made the most awful noise and rattling, I could not turn the car off. Thank goodness for two wonderful gentlemen who stopped and could not figure what was going on either. Could not get the battery cable ? off and the car started smoking,,,,,, Had to have the car towed to my house and then to the Toyota garage next day. And the final diagnosis from the serviceman was that he started the car 50 times and it always started..........I mentioned several people said it was probably the ignation or the starter motor? He said they could not do anything unless the car wouldn't start? Needless to say, I said my Goodbye to that
dealership and now I still have a car that I cannot trust to take me anywhere. I honestly have to say that this Toyota is a Lemon.
