15: Ford F-150
The F-150 has been on the block for a long time but with that prestige comes a lot of reliability issues. On the V8 models, there have been known issues with the timing chain, as well as overheating. These trucks also have a lot of issues with the automatic starting system, and once this shorts out, it can cost thousands of dollars to get it diagnosed (via Readers Digest).

The F-150 has long been the best-selling truck in America, and that’s for a reason. But when it comes to it, the issues are costly. You will spend quite a bit to keep this truck on the road long-term, which is why many consumers have decided to move toward other truck brands.
