“Noticed transmission rumble. Took vehicle to local dealership where I was told there was cross-contamination between the radiator and transmission. Apparently a known issue with this make and model. Informed it would be over $6000 to repair. I have owned the vehicle since 2005 and was never informed of the defect or the pending class-action suit.”

NHTSA complaint #10607514, filed 2014-07, 119,950 miles

“In november 2010 my transmission failed and had to be replaced. 3 months after having the transmission replaced I started having problems with the new transmission, I discovered I had to have the radiator replaced but it was too late. The new transmission has been ruin due to a faulty radiator install in the 2005 frontiers by Nissan.”

NHTSA complaint #10454178, filed 2012-04, 154,000 miles

“Transmission cooler failing and contaminating the transmission, repaired transmission cost was more that I can paid, fixed anyway but still not 100% good, haven't bought a new radiator, don't want the same problem again. I hope this will be a recall so I can have my transmission repair by Nissan and a radiator replace.”

NHTSA complaint #10467768, filed 2012-07, 100,865 miles

“My transmission is slipping. I have been told by a dealer I have radiator fluid in my transmission fluid. Apparently, this is a known problem with certain model year Nissan vehicles, due to a break in a transmission line that runs through the radiator. Please force Nissan to recall and repair this issue!!!”

NHTSA complaint #10483751, filed 2012-11, 120,000 miles

“I was driving on the highway and my truck shutters like going over shallow rumble strips for about 3 weeks. I realized it was my transmission and searched on transmission issues with my truck and found the big one (coolant leaking into the transmission fluid). I immediately flushed the coolant and the transmission fluid, performed the at cooler bypass operation and refilled. I'm now saying my prayers, taking my vitamins, and exercising hoping for the best.”
