I live in Central Florida and can count on one hand the number of times I have put it into four wheel drive since buying. I do not go off-road, but do travel about 450 miles per week on highways for work. I had a warning show up two days ago that said "4 wheel drive unavailable- service required". I drove to dealership, they kept overnight. Called me yesterday to tell me it needed a new transfer case, $3410. I asked if it was safe to drive in 2 wheel and they said the car would eventually "shut down".. they did not know if it would happen tomorrow, next week, or next year. I asked how I would know when it was going to happen and they said it would get loud and make grinding noises...but right now, I am not hearing anything like that. In researching online, I am seeing that there were similar issues with 2014-2017 models as well. I do not know a whole lot about the car, that's why I am here seeking some input. Thanks all,
