I have a 2014 Ford Focus ST with 34k miles on it. It sometimes has a rough idle at a stop or cold startup (almost stalls out), which I'm thinking could be from carbon build up since it's a GDI turbo engine. Is this car a maintenance nightmare? I've already had a ton of suspension, computer, and door latch issues luckily all covered by warranty.
Would you get rid of this car while it still has value left?? I'm very tempted to go get a 6-speed Corolla...
