Our 2015 nissan quest with 47500 miles on it started making a bad noise on sunday 3/26/18, and hesitating as i was driving with my 3 kids back from a short trip. it was a horrible sensation to not know if i could make it home safe with my kids. took it to nisssn to check it out on monday 3/27/18. i got a call today to tell me that the radiatior gar a leak into the transmission. the transmission is out. i need to replace the transmission, and radiator. total repair cost almost $6000. they submitted a claim under warranty, which was turned down by nissan because it was not the transmission that fail on it\\\\\\\'s own. but, provoked by the leak by radiator, which is not covered under warranty. i purchased this vehicle in aug. 17. and, cannot believe that nissan is getting away with not fixing this known issue on their faulty radiators on many of their vehicles. i cannot afford the 6k to fix it. so, i don't know what i will do.
