We bought a brand new Ford Escape 3 years ago. The warranty booklet states that the car has to undergo maintenance every 3 months of 5,000 kilometers whichever comes first. Since we have 2 cars, obviously the 3 months became the rule. When we asked what would happen if we don't follow the 3 months schedule, the service advisor said it will void the warranty. What a coincidence, when the 3-year warranty expired this year, there was something wrong with the car's air conditioning system. I was dejected because we were spending so much for that 3-month maintenance schedule and this happens. I asked the tech secretly about the need for maintenance and the honest answer I got was 6 months - maintenance check of twice a year will suffice since the car is quite new. So there, if you want to save on maintenance and your car has no more warranty, get the twice a year maintenance checkup schedule.
