12: Lincoln Zephyr
This interesting sedan was a breath of fresh air for Lincoln in 2006, but after the initial beauty wore off, you could tell that the Zephyr was nothing special. The look and feel of the car are two benefits of driving one, but the reliability is shaky at best. The engine has many issues with the head gaskets and timing chain (via Readers Digest).
The Zephyr has also been known to have premature fuel pump failures that are expensive to repair. You won’t find this car on any of the most reliable comparisons and that’s because maintenance on this car is expensive. That’s before drivers consider the fuses and interior items that tend to burn out as well.
