conduct a safety recall on certain vehicles equipped with the Bendix Intellipark system. On Sept. 1, 2021,
the supplier provides a final list of units they were actually able to update. There were 12 units that they
did not update, thus increasing the recall population by 12.

Chapter 301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to
you. The Act states that failure to repair a vehicle within 60 days after tender for repair shall be prima facie
evidence of an unreasonable time. However, circumstances of a particular situation may reduce the 60 day
period. Failure to repair a vehicle within a reasonable time can result in either the obligation to (a) replace the
vehicle with an identical or reasonably equivalent vehicle, without charge, or (b) refund the purchase price in
full, less a reasonable allowance for depreciation. The Act further prohibits dealers from selling a vehicle unless
