7: Dodge Nitro
The Nitro was another compact SUV Chrysler released over the last decade. The Nitro had an upright look and it seemingly caught on with consumers. The problem is that the Nitro was also one of the more unreliable offerings. The transmission was the main problem as it is with most Dodge products (via Readers Digest).

If you were unlucky, then you’d have the transmission fail early in the ownership of the car. The reliability of the Nitro is also questionable at best. The head gasket tends to blow from time to time and the cooling system also fails.
