2018 Premier, 70K miles, original owner. Started slipping and engaging with a thud from a stop. Then same between shifts, then really whining from a stop. Dealer installed factory re-man for $5,000.00. And no loaner! Said they only had loaners for warranty work, what a crappy dealer. Said it would cost at least four grand to repair, 10K past warranty. Should I have taken it to an independent? I didn't have the luxury of another ride except one of my motorcycles. Only other time I have had a tranny go was in another GM product, worst POS I ever owned, Pontiac Montana, purchased new, tranny replaced under warranty. With 65K, threw a rod!! Who the heck throws a rod in a Mini Van! The only other time that has happened to me was in a 14 year old, $100.00 6 cyl, 59 Ford F-100 that used a quart every 100 miles, but a modern era car, seriously, WTF. Why do I keep buying American cars?
