The 2.0 ecoboost motor has certainly proved to be far more reliable than the 1.6 and 1.5 four cylinder motors that Ford has used the past decade (the 3 cylinder 1.5 is new so we will see) But the 2.5 Duratec motor has a pretty good history as well and goes back to 2001 in North America. Which makes the level of problems - here on the forum - look greater than the reality. The reality appears to be people that have had a problem look for a forum to post up their problems. Reading here it's easy to worry that nearly every Maverick is at some moment going to be dead when you go out to start it. But as a member of this forum I do take comfort in CR s predictions and reviews. Since the Maverick is new it might be a few years to see if CR's predicted reliability is accurate. it took the surveys a couple of years to realize Hyundai greatly improved their quality in 1999 and it took a couple of years for surveys to reflect some Subaru models were having substantial engine and transmission problems. So in the past, CR's automotive surveys have been a bit slow to record brand improvements or brand slippage. Next is the fact that this is always data a year or two old. Considering that Ford is not a top 10 brand on reliability CR must have gotten what they felt were a sufficient number of responses. The Maverick is new so they probably were on the low end as there were not a lot of Mav's on the road. A typical low end sample size for a vehicle might only be a few hundred vehicles. CR says they don't report data on models they don't get enough responses on OR they combine that data with brand history. There are two potential problems that stand out. Both from the likelihood that another survey would get similar results and that the survey meets the test of surveying what it says it does. I could write a wall of text on it, but the short version is that CR's car reliability (as well as other products, since their annual survey to members asks about many products, not just cars) is statically valid. My degree is also in Poly Sci, which has a heavy emphasis on polling and statistics. I've been a subscriber to Consumer Reports for 40+ years.
