All of them!
Purchased in Nov 2019 at 169,000 miles. 4th owner. Was able to get copies of all warranty work and it looks like it had all the typical 6.4L issues. Many things replaced early on. Had the short block replaced at 95,000. Last owner recently had turbo chargers replaced. It had $26,500 of warranty work in it's first 3.5 yrs. Yikes! We are hopeful that the issues have been worked out and we are getting a good truck. Excellent condition inside and out and below market price. Fingers crossed!
