Is you Ford Explorer AWD?
As far as CX-5 goes, here we saw someone with major SkyActiv-MT manual transmission problem at 53,000 miles. We saw several who had failed SkyActiv-Drive automatic transmission at only several thousand miles. We saw guys had SkyActiv-G 2.5L engine replaced due to unfixable oil leak. We saw a guy fought with Mazda North American Operations to get his whole new CX-5 replaced due to unsolvable airbag warning. I understand these could be just isolated cases, but we also have to remember that there're more CX-5 owners who don't post here even if they have major problems! And consider there're only ⅓ number of CX-5 owner's for each CX-5 MY than Honda CR-V and Toyota RAV4, and with only 4 model years, we know these major problems, not related to complicated high tech issues for modern vehicles, are also likely under-reported as there're far less CX-5 owners than those Honda's and Toyota's. When I was with VW Passat forum for many years, and Passat is not well-known for good reliability, I'd seen all kind of problems but none of them involved engine or transmission replacement during warranty period!
On the other hand, we saw many CX-5 owners having good experience
so far. This makes me think that the reliability for Mazda is a hit and miss thing. Most people may get good quality CX-5 but a few others may not. This could be traced by the problems to be a small car manufacture like Mazda. They have less power to control suppliers who actually make parts for Mazda. So sometimes a bad batch of parts caused problems like some of the automatic transmissions installed in 2015.
