2: Kia Forte Koup
Kia is not shy when it comes to testing the waters with a new model. The company launched the Borego SUV in the middle of a recession. The Kia Forte Koup was the same concept, releasing a sports car when no one wants them. The naming of the car was bad enough, but the reliability of the car was even worse (via Cheers and Gears).
There were numerous transmission failures that affected this car when it was brand new. The warranty Kia offers was a big help, but not enough. Buyers were not convinced to get the Forte Koup and Kia quietly discontinued the model. Kia still sells a two-door model, but it isn’t called the Koup anymore.
