Is the Ford Flex 3.5 a good engine?

The Ford Flex 3.5 engine has generally proven itself to be reliable. Many EcoBoost engines, including the 3.5-liter EcoBoost, have delivered hundreds of thousands of miles without a single breakdown. However, like any engine, it is not perfect and there are a few common problems that have been reported. These include timing chain problems, carbon build-up, and longevity issues with spark plugs and ignition coils. Overall, the 3.5 EcoBoost engine is considered to be reliable with an excellent balance of power, torque, and efficiency.
It’s worth noting that the Ford Flex offers two engine options: the base 3.5-liter V6 engine and the twin-turbocharged 3.5-liter V6 EcoBoost engine. The base engine provides adequate power for daily driving, but it may feel strained when the vehicle is fully loaded with passengers and cargo. On the other hand, the EcoBoost engine, available in the Limited trim, offers better acceleration and performance in certain driving situations. However, upgrading to the EcoBoost engine also requires adding all-wheel drive.
In conclusion, the Ford Flex 3.5 engine, whether it’s the base V6 or the EcoBoost V6, is generally considered to be a good engine with reliable performance.
