5: Chevrolet Uplander
The upright SUV-style minivans sold by GM in the mid-2000s have started to pique the interest of buyers lately. These vans never sold well when they were new, so it doesn’t make sense why consumers want these. The engines were notably unreliable and the vans had many issues that made them questionable (via Readers Digest).

The Uplander was a van with a faulty V6 engine. When it was running right, the overheating problem would arise. And if you could skip those problems, the transmission probably would fail on you. The Uplander was not the best-looking van and didn’t stand out from the crowd.
