Your new motor vehicle will be accompanied by a maintenance guide. The maintenance guide sets forth the manufacturer’s recommendation for how often the vehicle should be presented to a dealership for routine maintenance. This includes oil changes, fuel filters, air filters and fluids. Manufacturers frequently criticize consumers for not having their vehicle maintained in accordance with those recommendations. This is called the “lack of maintenance defense.” And even though the maintenance may not have anything to do with the customer’s concern, the manufacturer will raise it as a defense for why they should not have to repair your vehicle. You should protect yourself from these bogus arguments. The best way to do so is to have your vehicle regularly maintained. Keep records of all maintenance.
