A warranty to or for the benefit of a consumer under this chapter, whether express or implied, extends to any natural person who is in the family or household of the consumer or who is a guest in the consumer's home if it is reasonable to expect that such person may use or be affected by the consumer goods and who is injured in person by breach of the warranty. This section does not displace principles of law and equity that extend a warranty to or for the benefit of a consumer to other persons. The operation of this section may not be excluded, modified or limited.
