Mitsubishi has been in the auto industry for almost 100 years. They offer a 10-year, 100,000 mile powertrain warranty and a 7-year, 100,000 mile corrosion warranty, which are among the longest in the industry. However, their warranty has some drawbacks as technical issues may not be fully covered and problems not caused by the manufacturer are not covered. Overall, Mitsubishi provides excellent long-term warranty coverage but it may not cover all potential issues.
