14: Jaguar X-Type
Sold right alongside the S-Type was the X-Type, which was also based on the same platform. Both were Ford products and also suffered from the same reliability problems. Ford was a confused company during this time and the X-Type was evidence of that because the car didn’t know if it was a sports sedan or a high-end luxury car (via Car and Driver).
Luckily, Jaguar would change the brand’s focus years later but the X-Type is still the butt of many Jaguar quality jokes to this day. The car would routinely spend a good deal of time in the repair shop and the repairs were often costlier than owners anticipated.
