Can anyone let me know what are the most expensive repairs that an XTS owner is likely to encounter? I suppose that as with most potential Cadillac owners I know not to expect the perfect reliability that you might expect with a Lexus. I know that with some Fords and Lincolns there are water pump issues that might require you to spend $7K on a new engine. I love the XTS and right now a 2016-2019 is my my top choice for the new car that I expect to buy in the next month or so. I would just like to hear what might be the worst case problems, and how much they typically cost, that one might expect for this car. Basically how much should you expect to need to set aside to make sure you can always keep the car running?
