My 2013 Ford Edge had a transmission issue. It has 97000 miles on it. Took it to a dealer and they replaced 2 parts costing over $1800. After driving for 2 weeks, transmission locked up in 2nd gear. Then it just started skipping gears intermittently. Took it back to dealer and was told the transmission was just coming apart piece by piece and I needed to replace it at a cost of $8000! This is ridiculous!
