40: Jaguar S-Type
If you remember the Jaguar brand in the 2000s, then you remember seeing the S-Type. There wasn’t much that was different about this car from the X-Type, other than the styling. The problem was that this car was just as unreliable. The repair costs were so high that it would break the bank early on and this car didn’t have a good warranty from the factory (via Auto Trader).
There were a few V8 models that were released that were fun to drive when they were new, but the same problem persisted which surrounded the reliability. If the car spends more time in the shop than it does on the road, who wants it? That was the problem with the S-Type and it led to the sales of the Jaguar brand diminishing greatly.
