Since yours is a 2006 model, it doesn't have the infamous turbocharged and direct injected Ford EcoBoost engine. Good for you. The EcoBoost engine, in production since 2010, has had head gasket issues because of a design flaw in the cooling channels near the cylinder head. They fixed it in 2020. And since the displacement tends to be small relative to the power output, heat and mechanical strain can be issues in general.

One of our cars is a 2005 Mitsubishi Colt that runs without any problems apart from the infotainment system (the small digital display and the radio) being dead. It's gone through minor repairs only a couple of times apart from the usual wear and tear items but nothing costing more than €400 at the shop. The other is a 2012 Lexus 450h with a little shy of 200,000 km on the clock. I chose the make and model based on expected durability and reliability. It's got a naturally aspirated (no turbo) 3,5 l V6 with less power per liter of displacement than its European competition. Both direct and port injection meaning less chance of carbon buildup. I love the fuel economy and the smoothness of the hybrid power train. Only 6% of 15-year-old Toyota/Lexus hybrids have had their high-voltage batteries replaced - including cars that have been in accidents. Fingers crossed.

Today's trend is toward smaller turbocharged engines, which affects their durability. Even Lexus has caved. I really hope I won't have to buy a new car for a long time but when I do, I hope batteries have become much cheaper.
