“2005 Navigator has only 60,000 miles, spark plugs defected, dealer wants $1,500 to $2,500 to replace them, which is defect from manufacture. These spark plugs should be replaced due to defects from manufacture, and the recall only wants to pay $1,040 for the replacement of the spark plugs, why should I pay up front if they are manufacture fault and my Navigator only has 60,00 miles now and I purchased it new from the dealer in 2005.”
