Iowa Code § 322G.1
The general assembly recognizes that a motor vehicle is a major consumer acquisition and that a defective motor vehicle undoubtedly creates a hardship for the consumer. The general assembly further recognizes that a duly franchised motor vehicle dealer is an authorized service agent of the manufacturer. It is the intent of the general assembly that a good faith motor vehicle warranty complaint by a consumer be resolved by the manufacturer within a specified period of time. It is further the intent of the general assembly to provide the statutory procedures whereby a consumer may receive a replacement motor vehicle, or a full refund, for a motor vehicle which cannot be brought into conformity with the warranty provided for in this chapter. However, this chapter does not limit the rights or remedies which are otherwise available to a consumer under any other law.
