39: Hyundai Sonata
The Sonata has been a fixture of the Hyundai lineup for the last couple of decades. The current Sonata is not the most imaginative sedan, but its price tag and warranty are stellar. Nevertheless, the Sonata still has its fair share of reliability issues due to vital transmission problems. Few cars offer the intrinsic value that the Sonata does, but most consumers aren’t interested in replacing their vehicle’s transmission nonetheless.
Hyundai will only cover the repairs up to a certain point. Then, it becomes very expensive to do a replacement. Aside from the transmission reliability issues, the Sonata is lacking in other features as well, not to mention the extreme design. New car shoppers would be advised to avoid the Sonata altogether as there are other more reliable choices on the market.
