Rules relating to defective motor vehicles are dealt with in Section 51:1941 et seq of Louisiana Revised Statutes, Title 51, Chapter 27 (Motor Vehicle Warranties).  Nonconformity is defined in Section 51:1941 to include both specific and generic defect or malfunction, or any defect or condition which substantially impairs the use, market value or both of a motor vehicle.

According to Section 51:1942, if a consumer reports any nonconformity to the manufacturer regarding the motor vehicle, within the prescribed time limit, the manufacturer, its agent, or its authorized dealer should make such repairs as are necessary to conform the vehicle to such warranty.  The prescribed time limit is either before the expiration of the warranty or during a period of one year following the date of the original delivery of the motor vehicle to a consumer, whichever is the earlier date.

As prescribed in Section 51:1944, if nonconformity in a motor home has not been repaired within the time period, then the consumer has a remedy against the manufacturer.  In those circumstances the manufacturer should either replace the motor vehicle with a comparable new motor vehicle or accept return and refund full purchase price plus any amounts paid by the consumer at the time of sale and all collateral costs, after deducting a reasonable allowance for use.
