Transmission failure after 10K miles
 After 10k miles the car start making a whining noise when accelerating over 30 mph. Searching online reveals that it's a common problem that leads to complete transmission failure, however the dealer refuses to fix the noise until the transmission fails completely. It's not a pleasant experience driving a car with kids inside waiting for transmission to fail. Now I need to talk to lawyers and file for the Lemon Law. The acceleration overall is very bad, the car feels like an under powered big box on wheels. The interior quality is very low, the car squeaks from everywhere. Fuel economy is awful, I get around 10 mpg in the city and the car drives really bad. If you think you buy it because it's a Toyota think again because they are no longer what they used to be.
