6. Renault Alliance Encore

Introduced in 1984, the Renault Encore was a hatchback variant of the Alliance, aiming to offer compact luxury with European flair. Despite its initial acclaim, including being named Motor Trend’s Car of the Year in 1983, the Encore faced significant reliability issues. Owners reported problems such as overheating, oil leaks, and interior components failing prematurely. These quality concerns led to a tarnished reputation and contributed to Renault’s decision to exit the U.S. market in 1987. (money.cnn.com)
