To the consumer , 'bumper to bumper' warranty gives the impresssion that EVERY defective part is covered at no cost . Not so. The 2004 Santa Fe i bought my folks have had 2 license plate bulbs go bad within a 3 month period with just over 12,000 miles on the car. The Hyundai Dealer wanted $21 to change out the bulb because the 'bumper to bumper' warranty doesnt cover light bulbs. Light bulbs going bad (even the same one within a 3 month time frame) are not covered ; according to the Service Manager : " Light bulbs are considered a maintenance item". I say , thats fine if one goes out every 3 or 4 years...but the same one within 3 months at just over 12,000 miles ??? Come on.
I post this just so you are aware. There are other things which the 'bumper to bumper warranty' does not cover as well.
